CHAPTER 1 Getting to Know the IES-1248

This chapter describes the system features, specifications and applications of your IES-1248.

The IES-1248 is an IP-based DSLAM (Internet Protocol Digital Subscriber Line Access Multiplexer) that connects ADSL subscribers to the Internet. As a high-performance but yet compact platform, it can conveniently deliver broadband Internet access to telephone company central offices, multi-tenant units (MTUs), hospitals, hotels, schools, university campuses and ISPs. The IES-1248's low cost and easy management make it a perfect DSL-provider solution.

The IES-1248 platform allows for convenient management and support of ADSL technology. Up to 48 ADSL subscribers can simultaneously utilize a wide range of powerful broadband services.

1.1 System Description

Four Telco-50 Connectors

There are four Telco-50 connectors for ADSL and POTS connections.

1000/100 Mbps Ethernet Ports

The IES-1248 has two 1000/100Mbps auto-sensing Ethernet ports.

They allow you to:

• Connect the IES-1248 to a second-level switch
• Daisy-chain other IES-1248

Two Slots for Mini GBIC Modules

The mini GBIC (Gigabit Interface Converter) module transceivers allow flexibility in connection options. You can use mini GBIC transceivers for fiber connections to backbone Ethernet switches.

Stacking

Daisy-chain up to three IES-1248 (or other Ethernet devices).

Integrated Splitters

The integrated DSL splitter eliminates the need to use external splitters that separate the voice-band and ADSL signals.

Console Port

Use the console port for local management of the IES-1248.

Fans

The fans cool the IES-1248 sufficiently to allow reliable operation of the IES-1248 in even poorly ventilated rooms or basements. To conserve energy and reduce noise, the fan speed depends on the temperature.

IP Protocols

• IP Host (No routing)
• Telnet for configuration and monitoring
  SNMP for management

SNMP MIB II (RFC 1213)
SNMP v1 RFC 1157
- SNMPv2, SNMPv2c or later version
- Bridge MIBs (RFC 1493, 2674)

ADSL2:G.992.3,G.992.4
ADSL2+: G.992.5

• Rate adaptation support

IEEE 802.1p Priority

Your IES-1248 uses IEEE 802.1p Priority to assign priority levels to individual PVCs.

Multiple PVC and ATM QoS

The IES-1248 allows you to use different channels (also called Permanent Virtual Circuits or PVCs) for different services or subscribers. Define channels¹ on each DSL port for different services or levels of service and assign each channel a priority. ATM Quality of Service (QoS) allows you to regulate the average rate and fluctuations of data transmission. This helps eliminate congestion to allow the transmission of real time data (such as audio and video).

IEEE 802.1x Port-based Authentication

The IES-1248 supports the IEEE 802.1x standard for centralized user authentication and accounting management through an optional network authentication (RADIUS) server.

2684 Routed Mode

The IES-1248 can handle 2684 routed mode traffic.

Downstream Broadcast

The IES-1248 can block downstream broadcast packets from being sent to specified VLANs on specified ports.

Management

• Remote configuration backup/restore and firmware upgrade
• SNMP manageable
• Text-based management locally via console port and remotely via telnet
• Editable plain text based configuration file

Security

• Password protection for system management
  VLAN

MAC (Media Access Control) Filter

Use the MAC filter to accept or deny incoming frames based on MAC (Media Access Control) address(es) that you specify. You may enable/disable the MAC filter on specific ports. You may specify up to ten MAC addresses per port.

MAC (Media Access Control) Count Filter

You can limit the number of MAC addresses that may be dynamically learned on a port. You may enable/disable the MAC count filter on individual ports.

Static Multicast

Use static multicast to allow incoming frames based on multicast MAC address(es) that you specify. This feature can be used in conjunction with IGMP snooping and IGMP proxy to allow multicast MAC address(es) that are not learned by IGMP snooping or IGMP proxy.

IGMP Proxy

In a simple tree network, the system can proxy multicast traffic in order to improve network performance.

IGMP Snooping

With IGMP snooping, group multicast traffic is only forwarded to ports that are members of that group. IGMP Snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through your IES-1248.

System Monitoring

• System status (link status, rates, statistics counters)
• Temperatures, voltage reports and alarms.

System Error Logging

The IES-1248's system error log will record error logs locally. These logs may be viewed again after a warm restart.

Alarm LED

An ALM (alarm) LED lights when the IES-1248 is overheated, the fans are not working properly, the voltage readings are outside the tolerance levels or an alarm has been detected on the ALARM input pins.

Bandwidth Control

The IES-1248 supports rate limiting in 32 Kbps increments allowing you to create different service plans

Quality of Service

• Four priority queues for ENET and eight priority queues for downstream PVC so you can ensure mission-critical data gets delivered on time.
• Follows the IEEE 802.1p priority setting standard.

STP (Spanning Tree Protocol) / RSTP (Rapid STP)

(R)STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows a switch to interact with other (R)STP -compliant switches in your network to ensure that only one path exists between any two stations on the network.

1.2 Applications

These are the main applications for the IES-1248:

• Internet access and multimedia services for Multiple Tenant Units (MTU).
• Other applications include telemedicine, surveillance systems, remote servers systems, cellular base stations and high-quality teleconferencing.

1.2.1 MTU Application

The following diagram depicts a typical application of the IES-1248 with ADSL modems, in a large residential building, or multiple tenant unit (MTU), that leverages existing phone line wiring to provide Internet access to all tenants. Note that ADSL service can coexist with voice service on the same line.

Figure 1 MTU Application

1.2.2 Curbside Application

The IES-1248 can also be used by an Internet Service Provider (ISP) in a street cabinet to form a "mini POP (Point-of-Presence)" to provide broadband services to residential areas that are too far away from the ISP to avail of DSL services. Residents need an ADSL modem, connected as shown in the previous figure.

Figure 2 Curbside Application

CHAPTER 2 Hardware Installation

This chapter explains how to install the IES-1248.

2.1 General Installation Instructions

3.2 1000/100M Auto-Sensing Ethernet

The IES-1248 has two 1000/100Mbps auto-sensing Ethernet ports. There are two factors related to Ethernet: speed and duplex mode. In 1000/100Mbps Fast Ethernet, the speed can be 100Mbps or 1000Mbps and the duplex mode can be half duplex or full duplex. The auto-negotiation capability makes one Ethernet port able to negotiate with a peer automatically to obtain the connection speed and duplex mode that both ends support.

When auto-negotiation is turned on, an Ethernet port on the IES-1248 negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer Ethernet port does not support auto-negotiation or turns off this feature, the IES-1248 determines the connection speed by detecting the signal on the cable and using half duplex mode. When the IES-1248's auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and duplex mode when making a connection, thus requiring you to make sure that the settings of the peer Ethernet port are the same in order to connect.

Use the Ethernet ports for subtending. You can daisy chain more IES-1248 or other Ethernet switches.

Use with the following copper Ethernet cables: 1000Base-T 4-pair UTP Cat. 5, up to 100m

Note: For better performance and lower radiation noise, use shielded Ethernet cables.

Each 1000/100M port is paired with a mini GBIC slot. The IES-1248 uses up to one connection for each pair for a total of two possible gigabit connections (one from each of the two pairs). The IES-1248 uses the mini GBIC transceiver whenever it has a connection.

3.2.1 Ethernet Default Settings

• Speed: Auto
• Duplex: Auto

3.3 SFP Mini GBIC Slots

The SFP slots can each house a mini GBIC (Gigabit Interface Converter) transceiver. A transceiver is a single unit that houses a transmitter and a receiver. The IES-1248 does not come with a transceiver. You must use a transceiver that complies with the Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See the SFF committee's INF-8074i specification Rev 1.0 for details.

You can change transceivers while the IES-1248 is operating. You can use different transceivers to connect to Ethernet switches with different types of fiber-optic connectors.

Note: To avoid possible eye injury, do not look directly into an operating fiber-optic module's connectors.

Figure 9 SFP Mini GBIC Slot

• Type: SFP connection interface
• Connection speed: 1 Gigabit per second (Gbps)

3.3.1 Transceiver Installation

Use the following steps to install a mini GBIC transceiver (SFP module) in the SFP slot.

Note: The SFP slot is at an angle. Do not attempt to straighten it.

1 Remove the dust cover from the transceiver.
2 For transceivers with a flip-up or flip-down latch, close the latch.
3 Insert the fiber-optic cables into the transceiver (you may need to remove cable dust covers).
4 Insert the transceiver into the IES-1248's SFP slot with the exposed section of PCB board facing down.
5 Press the transceiver firmly until it clicks into place.

Figure 10 Transceiver Installation

Figure 11 Installed Transceivers

3.3.2 Transceiver Removal

Use the following steps to remove a mini GBIC transceiver (SFP module) from the IES-1248.

1 Remove the fiber-optic cables from the transceiver.
2 Unlock the transceiver's latch (latch styles vary).
3 Pull the transceiver out of the slot.
4 Put the transceiver's dust cover on the transceiver.

Figure 12 Opening the Transceiver Latch

Figure 13 Removing the Transceiver

3.4 Console Port Connection

For local management, you can use a computer with terminal emulation software configured to the following parameters:

• VT100 terminal emulation
  9600 bps
• No parity, 8 data bits, 1 stop bit
• No flow control

Connect the mini-RJ-11 male end of the console cable to the console port of the IES-1248. Connect the female end to a serial port (COM1, COM2 or other COM port) of your computer.

3.5 ALARM Connections

A closed circuit on the ALARM input pins indicates an alarm. Pins 7 and 3 are alarm input one. Pins 8 and 4 are alarm input two. Pins 9 and 5 are alarm input 3.

The IES-1248 signals an alarm when it detects an alarm on the ALARM input pins or the IES-1248.

To signal an alarm, the IES-1248 opens the circuit for pins 1 and 6 (the common pin) and closes the circuit for pins 2 and 6.

Examples of an alarm on the IES-1248 are when the IES-1248's voltage or temperature is outside of the normal range.

Figure 14 ALARM Pins Layout

3.6 ADSL Connections

Connect the lines from the user equipment (ADSL modems) to the USER Telco-50 connector and the lines from the central office switch or PBX (Private Branch Exchange) to the CO Telco-50 connector. Make sure that the USER line and the CO lines are not shorted on the MDF (Main Distribution Frame).

The line from the user carries both the ADSL and the voice signals. For each line, the IES-1248 has a built-in splitter that separates the high frequency ADSL signal from the voice band signal and feeds the ADSL signal to the IES-1248, while the voice band signal is diverted to the CO port. See Chapter 4 on page 61 for more information on the Telco-50 connections.

CHAPTER 4

MDF Connections

This chapter shows you how to connect the Telco-50 connectors to an MDF.

4.1 MDF Connections Overview

Observe the following before you start:

• See Appendix B on page 445 for the gauge of telephone wire to use.
• Follow the pin assignments shown in Appendix C on page 449 to wire Telco-50 cables to Telco-50 connectors.
• See Chapter 1 on page 41 and Appendix C on page 449 for details on how to make the management connections.

4.2 MDF (Main Distribution Frame)

An MDF is usually installed between subscribers' equipment and the telephone company (CO) in a basement or telephone room. The MDF is the point of termination for the outside telephone company lines coming into a building and the telephone wiring in the building.

Figure 15 MDF (Main Distribution Frame) Wiring

• Connect wiring to end-user equipment to the lower ports of an MDF and connect wiring from the telephone company to the upper ports of an MDF (see the previous figure).

• Some MDFs have surge protection circuitry built in between the two banks; thus, do not connect telephone wires from the telephone company directly to your IES-1248.

• Use a punch-down tool to seat telephone lines into MDF blocks.

• Multiple upper and lower MDF port connections are shown as one line in the following figures.

4.3 Telco-50 Cables

Telco-50 cables are used for data and voice applications with MDFs (Main Distribution Frame), patch panels and distribution boxes. They can also be used as extension cables. Telco-50 cables are made up of 25 twisted-pair copper wires.

Connect a Telco-50 connector to one end of the cable (see Appendix C on page 449 for pin assignments) and connect the other end directly to an MDF; alternatively attach RJ-11 connectors and connect directly to DSL modem(s).

Figure 16 Telco-50 Cable with RJ-11 Connectors

4.4 Telco-50 Connections

The internal DSL splitters separate the voice signals from the DSL signals. They feed the DSL signals to the IES-1248 and divert the voice signals to the CO Telco-50 connectors.

Connect the CO Telco-50 connectors to the PBX or PSTN/ISDN switch.

Connect the USER Telco-50 connectors to the subscribers' telephone wiring. In most multi-tenant unit applications, the USER pins connect to the subscribers' telephone wiring via Main Distribution Frame (MDF).

See the pin assignments in Appendix C on page 449 and Section 4.5 on page 63 for details on Telco-50 connections.

4.5 MDF Scenarios

The following figure gives an overview on a possible installation scenario for the IES-1248. Data and voice signals can coexist on the same telephone wiring.

Figure 17 Installation Overview Example

You can also attach RJ-11 connectors to the Telco-50 cable and connect directly to a DSL modem(s) or patch panel. This chapter discusses connections using MDFs.

4.6 Typical MDF Scenarios

This section describes typical installation scenarios.

4.6.1 Installation Scenario A

You want to install the IES-1248 in an environment where there are no previously installed MDFs. There is no phone service and you want to install the IES-1248 for data-access only.

You may connect using an MDF or attach RJ-11 connectors to the non-IES-1248 end of the Telco-50 cable and then connect to DSL modems directly.

CHAPTER 8

Initial Configuration

This chapter describes initial configuration for the IES-1248. See Appendix A on page 443 for various default settings of the IES-1248.

8.1 Initial Configuration Overview

This chapter shows what you first need to do to provide service to ADSL subscribers.

8.2 Initial Configuration

This chapter uses the web configurator for initial configuration. See the CLI chapters for information on the commands. Use Internet Explorer 6 and later versions with JavaScript enabled.

1 Log in to the web configurator. See Section 7.3 on page 73 for instructions.
2 In the navigation panel, click Basic Setting, IP Setup. The IP Setup screen appears.

Figure 31 IP Setup

3 Use this screen to change the IP address, subnet mask, and default gateway IP address for your network. Apply the settings.

Note: If you change the IP address of the IES-1248, after you click Apply IP setting, you have to use the new IP address to log into the web configurator again.

4 If your subscribers use VPI 0 and VCI 33 (the default for all of the ADSL ports), go to step 13. Otherwise, use the following steps to change the VPI and VCI settings for all of the ADSL ports.

First, you will delete the default virtual channel from all of the ADSL ports. (You cannot edit it). Then, you will configure a new virtual channel for a port and copy it to the other ADSL ports.

Adding another virtual channel without deleting the default virtual channel is not recommended since you cannot set the new channel to be the port's super channel. The super channel can forward frames belonging to multiple VLAN groups (that are not assigned to other channels). A channel that is not the super channel can only forward frames with a single VLAN ID (that is configured on that channel). In this case, the IES-1248 drops any frames received from the subscriber that are tagged with another VLAN ID.

5 In the navigation panel, click Basic Setting, xDSL Port Setup. The xDSL Port Setup screen appears.

Figure 32 xDSL Port Setup

6 Click VC Setup. The following screen appears.

CHAPTER 13 Switch Setup

The Switch Setup screen allows you to set up and configure global device features.

13.1 GARP Timer Setup

GARP (Generic Attribute Registration Protocol) allows network devices to register and de-register attribute values with other GARP participants within a bridged LAN. GARP is a protocol that provides a generic mechanism for protocols that serve a more specific application, for example, GVRP (GARP VLAN Registration Protocol). GARP and GVRP are the protocols used to automatically register VLAN membership across switches.

Switches join VLANs by making a declaration. A declaration is made by issuing a Join message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All message terminates all registrations. GARP timers set declaration timeout values.

13.2 Switch Modes

The IES-1248 supports standalone and daisychain switch modes.

13.2.1 Standalone Switch Mode

"Standalone switch mode" relates to the IES-1248's operational behavior, not a standalone network topology. The standalone switch mode allows either or both of the IES-1248's Ethernet ports to connect to the backbone Ethernet network. You can also connect one of the IES-1248's Ethernet ports to the Ethernet network and the other to another IES-1248 (see Figure 52 on page 110 for an example). When the IES-1248 is in standalone mode, you can use it in a network topology that uses loops (you should also enable RSTP). You can have multiple IES-1248 connected on the same network and set both of them to use standalone mode in order to use them with a network topology that uses loops.

Standalone switch mode with port isolation enabled blocks communications between subscriber ports on an individual IES-1248. However, one IES-1248's subscribers can communicate with another IES-1248's subscribers if the two IES-1248's Ethernet ports are connected to each other (see Figure 52 on page 110 for an example). If you have multiple IES-1248 connected on the same network and set to standalone mode, they do not all need to have the same port isolation setting.

13.2.2 Port Isolation with Standalone Switch Mode Example

The following graphic shows IES-1248 1 and 2 connected to each other and the Ethernet backbone switch (3) in a network topology that creates a loop. The IES-1248 are using the standalone switch mode and have RSTP enabled.

In this example, both IES-1248 have port isolation turned on. Communications between A and B must first go through another switch (3 in the figure). However, A and B can communicate with C without their communications going through another switch or router.

Figure 52 Port Isolation with Standalone Switch Mode Example

13.2.3 Daisychain Switch Mode

Daisychain switch mode sets the IES-1248 to use Ethernet port one (ENET 1) as an uplink port to connect to the Ethernet backbone and Ethernet port two (ENET 2) to connect to another (daisychained or subtending) IES-1248. The daisychain switch mode is recommended for use in a network topology that does not have loops. When you daisychain multiple IES-1248 they must all be set to daisychain mode.

Daisychain switch mode with port isolation enabled blocks communications between subscriber ports on an individual IES-1248 and between the subscribers of any daisychained IES-1248 (see Figure 53 on page 111 for an example). Use the same port isolation setting on all IES-1248 that you set up in a daisychain.

13.2.4 Port Isolation with Daisychain Switch Mode Example

In the example below, the IES-1248 1 has its Ethernet port one (ENET 1) connected to the Ethernet backbone switch (3) and it's Ethernet port two (ENET2) connected to Ethernet port one (ENET 1) of the daisychained IES-1248 (2).

With port isolation turned on, communications between A and B must first go through another switch or router (3 in the figure). A and B also cannot communicate with C without their communications going through another switch or router.

The following table describes the labels in this screen.

Table 15 Switch Setup

LABEL	DESCRIPTION
MAC Address Learning Aging Time	Enter a time from 10 to 10,000 seconds. This is how long all dynamically learned MAC addresses remain in the MAC address table before they age out (and must be relearned). Enter 0 to disable the aging out of MAC addresses.
	GARP Timer: Switches join VLANs by making a declaration. A declaration is made by issuing a Join message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All message terminates all registrations. GARP timers set declaration timeout values. Click here for more information on VLANs.
Join Timer	Join Timer sets the duration of the Join Period timer for GVRP in milliseconds. Each port has a Join Period timer. The allowed Join Time range is between 100 and 65535 milliseconds; the default is 200 milliseconds.
Leave Timer	Leave Timer sets the duration of the Leave Period timer for GVRP in milliseconds. Each port has a single Leave Period timer. Leave Time must be two times larger than Join Timer; the default is 600 milliseconds.
Leave All Timer	Leave All Timer sets the duration of the Leave All Period timer for GVRP in milliseconds. Each port has a single Leave All Period timer. Leave All Timer must be larger than Leave Timer.
Port Isolation Active	Turn on port isolation to block communications between subscriber ports. When you enable port isolation you do not need to configure the VLAN to isolate subscribers.
MAC Anti-Spoofing	Select this if you want the IES-1248 to generate an alarm and issue a SNMP trap when an existing MAC address appears on another port.
Switch Mode	Select Standalone to use both of the IES-1248's Ethernet ports (ENET 1 and ENET 2) as uplink ports.Note: Standalone mode is recommended for network topologies that use loops.Use Daisychain mode to cascade (daisychain) multiple IES-1248. The IES-1248 uses Ethernet port one (ENET 1) as an uplink port to connect to the Ethernet backbone and uses Ethernet port two (ENET 2) to connect to another (daisychained or subtending) IES-1248.Note: Daisychain mode is recommended for network topologies that do not use loops.
Priority Queue Assignment	IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer frame that contains bits to define class of service. Frames without an explicit priority tag are given the default priority of the ingress port. Use the next two fields to configure the priority level-to-physical queue mapping.The device has 4 physical queues that you can map to the 8 priority levels for outgoing Ethernet traffic. The device has 8 physical queues that you can map to the 8 priority levels for outgoing ADSL traffic. Traffic assigned to higher index queues gets through the device faster while traffic in lower index queues is dropped if the network is congested.
Priority Level	The following descriptions are based on the traffic types defined in the IEEE 802.1d standard (which incorporates IEEE 802.1p).
Priority 7	Typically used for network control traffic such as router configuration messages.
Priority 6	Typically used for voice traffic that is especially sensitive to jitter (jitter is the variations in delay).
Priority 5	Typically used for video that consumes high bandwidth and is sensitive to jitter.
Priority 4	Typically used for controlled load, latency-sensitive traffic such as SNA (Systems Network Architecture) transactions.
Priority 3	Typically used for "excellent effort" or better than best effort and would include important business traffic that can tolerate some delay.
Priority 2	This is for "spare bandwidth".
Priority 1	This is typically used for non-critical "background" traffic such as bulk transfers that are allowed but that should not affect other applications and users.
Priority 0	Typically used for best-effort traffic.

Name	Enter a descriptive name that identifies this port. You can use up to 31 ASCII characters; spaces are not allowed.
Speed Mode	Select the type of Ethernet connection for this port. When you don't use auto-negotiation, you must make sure that the settings of the peer Ethernet port are the same in order to connect. Select Auto (auto-negotiation) to have the IES-1248 automatically determine the type of connection that the Ethernet port has. When the peer Ethernet device has auto-negotiation turned on, the IES-1248 negotiates with the peer to determine the connection speed. If the peer Ethernet port does not have auto-negotiation turned on, the IES-1248 determines the connection speed by detecting the signal on the cable and using full duplex. When an Ethernet port is set to Auto, the IES-1248 tries to make a fiber connection first and does not attempt to use the RJ-45 port if the fiber connection is successful. Select 100 Copper if the Ethernet port has a 100 MB electrical connection. Select 1000 Copper if the Ethernet port has a 1000 MB (1 gigabit) electrical connection. Select 1000 Fiber if the Ethernet port has a 1000 MB (1 gigabit) fiber optic connection.

CHAPTER 16 xDSL Port Setup

This chapter explains how to configure settings for profiles and individual ADSL ports. It also covers how to configure virtual channels and virtual channel profiles.

16.1 ADSL Standards Overview

These are the ADSL standards and rates that the IES-1248 supports at the time of writing. The actual transfer rates will vary depending on what the subscriber's device supports, the line conditions and the connection distance.

Table 18 ADSL Standards Maximum Transfer Rates

STANDARD	MAXIMUM DOWNSSTREAM	MAXIMUM UPSTREAM
G.dmt (IES-1248-51/51A)	8160 Kbps	1024 Kbps
G.dmt Annex B (IES-1248-53)	8160 Kbps	1024 Kbps
ETSI (IES-1248-53)	8160 Kbps	1024 Kbps
ANSI T1.413 issue 2 (IES-1248-51/51A)	8160 Kbps	1024 Kbps
ADSL2	12000 Kbps	1200 Kbps
ADSL2 Annex M (IES-1248-51/51A)	12000 Kbps	2400 Kbps
ADSL2+	25000 Kbps	1200 Kbps
ADSL2+ Annex M (IES-1248-51/51A)	25000 Kbps	2400 Kbps

16.2 Downstream and Upstream

Downstream refers to traffic going out from the IES-1248 to the subscriber's ADSL modem or router. Upstream refers to traffic coming into the IES-1248 from the subscriber's ADSL modem or router.

16.3 Profiles

A profile is a table that contains a list of pre-configured ADSL settings. Each ADSL port has one (and only one) profile assigned to it at any given time. You can configure multiple profiles, including profiles for troubleshooting. Profiles allow you to configure ADSL ports efficiently. You can configure all of the ADSL ports with the same profile, thus removing the need to configure the ADSL ports one-by-one. You can also change an individual ADSL port by assigning it a different profile.

For example, you could set up different profiles for different kinds of accounts (for example, economy, standard and premium). Assign the appropriate profile to an ADSL port and it takes care of a large part of the port's configuration maximum and minimum transfer rates. You still get to individually enable or disable each port, as well as configure its channels and operational mode.

16.4 Interleave Delay

Interleave delay is the wait (in milliseconds) that determines the size of a single block of data to be interleaved (assembled) and then transmitted. Interleave delay is used when transmission error correction (Reed-Solomon) is necessary due to a less than ideal telephone line. The bigger the delay, the bigger the data block size, allowing better error correction to be performed.

Reed-Solomon codes are block-based error correcting codes with a wide range of applications. The Reed-Solomon encoder takes a block of digital data and adds extra "redundant" bits. The Reed-Solomon decoder processes each block and attempts to correct errors and recover the original data.

16.4.1 Fast Mode

Fast mode means no interleaving takes place and transmission is faster (a "fast channel"). This would be suitable if you have a good line where little error correction is necessary.

16.5 Configured Versus Actual Rate

You configure the maximum rate of an individual ADSL port by modifying its profile (see Chapter 17 on page 137) or assigning the port to a different profile (see Section 16.7.1 on page 123). However, due to noise and other factors on the line, the actual rate may not reach the maximum that you specify.

Even though you can specify arbitrary numbers using the Edit Profile screen, the actual rate is always a multiple of 32 Kbps. If you enter a rate that is not a multiple of 32 Kbps, the actual rate will be the next lower multiple of 32Kbps. For instance, if you specify 60 Kbps for a port, the actual rate for that port will not exceed 32 Kbps, and if you specify 66 Kbps, the actual rate will not be over 64Kbps.

Regardless of a profile's configured upstream and downstream rates, the IES-1248 automatically limits the actual rates for each individual port to the maximum speeds supported by the port's ADSL operational mode. For example, if you configure a profile with a maximum downstream rate of 25000 Kbps, and apply it to a port set to use G.dmt, the IES-1248 automatically uses a maximum downstream rate of 8160 Kbps. This means that if you configure a profile with very high rates, you can still use it with any port. See Table 18 on page 119 for a list of the maximum rates supported by the different ADSL standards.

16.6 Default Settings

The default profile always exists and all of the ADSL ports use the default profile settings when the IES-1248 is shipped. The default profile's name is set to DEFVAL_MAX.

See Appendix A on page 443 for the settings of the default profile and ADSL port default settings.

IGMP Filter Profile	The IGMP filter profile defines which multicast groups a port can join. Select a profile of IGMP filter settings to assign to this port. Use the IGMP Filter Profile screen to configure IGMP filter profiles (see Section 17.8 on page 148).
ADSL2/2+ feature	These are features available with ADSL2/2+. The subscriber's ADSL device must also support the individual features in order to use them. At the time of writing these features have not been fully tested and their performance and interoperability cannot be guaranteed.
Annex L	This field is not available for the IES-1248-53. Enable Annex L to use reach extended ADSL2. This allows increased connection distances.
Annex M	This field is not available for the IES-1248-53. Enable Annex M to use double upstream mode. This has the upstream connection use tones 6 to 63.
Annex I	This field is not available for the IES-1248-53. Enable Annex I to use all digital mode. With Annex I, the ADSL connection uses the full spectrum of the physical line and the user can not use POTS or ISDN service. This increases the upstream data rate.Note: The subscriber cannot use POTS or ISDN services when you enable Annex I.
PMM	Enable the Power ManageMent (PMM) feature to reduce the amount of power used overall and reduce the instances of the connection going down. PMM increases or decreases the transmission power based on line conditions. PMM also decreases the number of service interruptions.Select L2 to have the ADSL connection use power saving mode and reduce the rate when there is no traffic. The rate comes back up when there is traffic SELECT L3 to use both power management modes L2 and L3. L3 puts the ADSL connection to sleep mode.L0 power mode uses no power reduction. See the ITU-T G.992.3 standard for more on PMM and the power modes (states).
SRA	Enable Seamless Rate Adaptation (SRA) to have the IES-1248 automatically adjust the connection's data rate according to line conditions without interrupting service.
	Sudden spikes in the line's noise level (impulse noise) can cause errors and result in lost packets. Set the impulse noise protection minimum to have a buffer to protect the ADSL physical layer connection against impulse noise. This buffering causes a delay that reduces transfer speeds. It is recommended that you use a non-zero setting for real time traffic that has no error correction (like videoconferencing).
US INP	Set the minimum upstream (US) impulse noise protection setting.
DS INP	Set the minimum downstream (DS) impulse noise protection setting.
Max US TX PSD	Specify the maximum upstream transmit power. The unit of measure is 0.1 dBm/Hz; for example, to set the maximum upstream transmit power to -10 dBm/Hz, set this value to -100.
Max DS TX PSD	Specify the maximum downstream transmit power. The unit of measure is 0.1 dBm/Hz; for example, to set the maximum downstream transmit power to -10 dBm/Hz, set this value to -100.
L0 Time	Set the minimum time (in seconds) that the ADSL line must stay in L0 power mode before changing to the L2 power mode.
L2 Time	Set minimum time (in seconds) that the ADSL line must stay in the L2 power mode before reducing the power again in the L2 power mode.
L2 ATPR	Set the maximum Aggregate Transmit Power Reduction (ATPR) in decibels (dB) that is permitted in a L2 power reduction. The system can gradually decrease the ADSL line transmission power while it is in the L2 power mode. This is the largest individual power reduction allowed in the L2 power mode.
L2 ATPRT	Set the maximum Aggregate Transmit Power Reduction Total (ATPRT) in decibels (dB) that is permitted in the L2 power mode. This is the total transmit power decrease that is allowed to occur in the L2 power mode.
Max L2 Rate	Set the maximum transfer rate (in Kilobits per second) that is permitted while the port is in the L2 power mode. The supported range is 32~4096 Kbps in 4 Kbps increments. If you enter a number that is not a multiple of 4, the system uses the next lower multiple of 4. If you enter 39, for example, the system will use 36.
Min L2 Rate	Set the minimum transfer rate (in Kilobits per second) that is permitted while the port is in the L2 power mode. The supported range is 32~4096 Kbps in 4 Kbps increments. If you enter a number that is not a multiple of 4, the system uses the next lower multiple of 4. If you enter 39, for example, the system will use 36.
L0 to L2 Rate	Set the down stream transfer rate (in Kilobits per second) that serves as the threshold for whether the port is to use the L0 or the L2 power mode. The system changes from L0 mode to L2 mode when the downstream transfer rate stays below this threshold for L0 Time. The system changes back from L2 mode to L0 mode when the downstream transfer rate goes above this threshold. This rate must be less than or equal to one half of the Min L2 Rate and at least 16 Kbps.
Use this part of the screen to mask carrier tones. Masking a carrier tone disables the use of that tone on the ADSL port. Do this to have the system not use an ADSL line's tones that are known to have a high noise level. Each mask can use up to 8 hexadecimal digits (00000000~FFFFFF). Each hexadecimal digit represents 4 tones. The hexadecimal digit is converted to binary and a '1' masks (disables) the corresponding tone. The most significant bit defines the lowest tone number in a mask.
US Carrier	Mask0 represents tones 0~31. Mask1 represents tones 32~63. The most significant bit defines Tone 0. In other words, 0x0000001 means tone 31. For example, you could use 0xFFFFFF00 to disable upstream carrier tones 0~19 and leave tones 20~31 enabled.
DS Carrier(32~255)	Mask1 represents tones 32~63 Mask2 represents tones 64~95 Mask3 represents tones 96~127 Mask4 represents tones 128~159 Mask5 represents tones 160~191 Mask6 represents tones 192~223 Mask7 represents tones 224~255 For example, use 0x01000000 in Mask2 to disable downstream carrier tone 71. Use 0x03000000 in Mask2 to disable downstream carrier tones 70 and 71.
DS Carrier(256~511)	Mask0 represents tones 256~287
	Mask1 represents tones 288~319
	Mask2 represents tones 320~351
	Mask3 represents tones 352~383
	Mask4 represents tones 384~415
	Mask5 represents tones 416~447
	Mask6 represents tones 448~479
	Mask7 represents tones 480~511
	For example, use 0x00001000 in Mask1 to disable downstream carrier tone 307. Use 0x0000f000 in Mask1 to disable downstream carrier tones 304 to 307.
Apply	Click Apply to save your changes to the IES-1248's volatile memory. The IES-1248 loses these changes if it is turned off or loses power, so use the Config Save link on the navigation panel to save your changes to the non-volatile memory when you are done configuring.

16.8 Virtual Channels

Defining virtual channels (also called Permanent Virtual Circuits or PVCs) allows you to set priorities for different services or subscribers. You can define up to eight channels on each DSL port and use them for different services or levels of service. You set the PVID that is assigned to untagged frames received on each channel. You also set an IEEE 802.1p priority for each of the PVIDs. In this way you can assign different priorities to different channels (and consequently the services that get carried on them or the subscribers that use them).

For example, you want to give high priority to voice service on one of the ADSL ports.

Use the Edit Static VLAN screen to configure a static VLAN on the IES-1248 for voice on the port.

Use the ADSL Edit Port Channel Setup screen to:

• Configure a channel on the port for voice service.
• Set the channel to use the PVID of the static VLAN you configured.
• Assign the channel a high priority.

16.8.1 Super Channel

The IES-1248 forwards frames belonging to VLAN groups that are not assigned to specific channels to the super channel. Enable the super channel option to allow a channel forward frames belonging to multiple VLAN groups (that are not assigned to other channels). The super channel functions in the same way as the channel in a single channel environment. One port can have only one super channel.

16.8.2 LLC

LLC is a type of encapsulation where one VC (Virtual Circuit) carries multiple protocols with each packet header containing protocol identifying information. Despite the extra bandwidth and processing overhead, this method may be advantageous if it is not practical to have a separate VC for each carried protocol, for example, if charging heavily depends on the number of simultaneous VCs.

16.8.3 VC Mux

VC Mux is a type of encapsulation where, by prior mutual agreement, each protocol is assigned to a specific virtual circuit, for example, VC1 carries IP, VC2 carries IPX, and so on. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical.

16.8.4 Virtual Channel Profile

Virtual channel profiles allow you to configure the virtual channels efficiently. You can configure all of the virtual channels with the same profile, thus removing the need to configure the virtual channels one-by-one. You can also change an individual virtual channel by assigning it a different profile.

The IES-1248 provides two default virtual channel profiles: DEFVAL (for LLC encapsulation) and DEFVAL_VC (for VC encapsulation). By default, all virtual channels are associated to DEFVAL.

16.10 Priority-based PVCs

A PPVC (Priority-based PVC) allows you to give different priorities to PVCs that are members of the same VLAN.

The IES-1248 uses eight priority queues (also called levels) for the member PVCs. The system maps frames with certain IEEE 802.1p priorities to a PVC with a particular priority queue. The following table gives the factory default mapping.

Down Shift SNR	The downstream down shift signal to noise margin (0-31 dB). When the channel's signal to noise margin goes below this number, the device shifts to a lower transfer rate. Configure the downstream down shift signal to noise margin to be less than or equal to the target downstream signal to noise margin and greater than or equal to the minimum downstream signal to noise margin.
Add	Click Add to save your changes to the IES-1248's volatile memory. The IES-1248 loses these changes if it is turned off or loses power, so use the Config Save link on the navigation panel to save your changes to the non-volatile memory when you are done configuring.

17.2 ATM QoS

ATM Quality of Service (QoS) mechanisms provide the best service on a per-flow guarantee. ATM network infrastructure was designed to provide QoS. It uses fixed cell sizes and built-in traffic management (see Section 17.3 on page 140). This allows you to fine-tune the levels of services on the priority of the traffic flow.

17.3 Traffic Shaping

Traffic shaping is an agreement between the carrier and the subscriber to regulate the average rate and fluctuations of data transmission over an ATM network. This agreement helps eliminate congestion, which is important for transmission of real time data such as audio and video connections.

Note: Traffic shaping controls outgoing (downstream) traffic, not incoming (upstream).

17.3.1 ATM Traffic Classes

These are the basic ATM traffic classes defined by the ATM Forum Traffic Management 4.0 Specification.

17.3.1.1 Constant Bit Rate (CBR)

Constant Bit Rate (CBR) is an ATM traffic class that provides fixed bandwidth. CBR traffic is generally time-sensitive (doesn't tolerate delay). CBR is used for connections that continuously require a specific amount of bandwidth. Examples of connections that need CBR would be high-resolution video and voice.

17.3.1.2 Variable Bit Rate (VBR)

The Variable Bit Rate (VBR) ATM traffic class is used with bursty connections. Connections that use the Variable Bit Rate (VBR) traffic class can be grouped into real time (rt-VBR) or non-real time (nrt-VBR) connections.

The rt-VBR (real-time Variable Bit Rate) type is used with bursty connections that require closely controlled delay and delay variation. An example of an rt-VBR connection would be video conferencing. Video conferencing requires real-time data transfers and the bandwidth requirement varies in proportion to the video image's changing dynamics.

The nrt-VBR (non real-time Variable Bit Rate) type is used with bursty connections that do not require closely controlled delay and delay variation. An example of an nrt-VBR connection would be non-time sensitive data file transfers.

17.3.1.3 Unspecified Bit Rate (UBR)

The Unspecified Bit Rate (UBR) ATM traffic class is similar to the ABR traffic class for bursty data transfers. However, while ABR gives subscribers a set amount of bandwidth, UBR doesn't guarantee any bandwidth and only delivers traffic when the network has spare bandwidth.

17.3.2 Traffic Parameters

These are the parameters that control the flow of ATM traffic.

17.3.2.1 Peak Cell Rate (PCR)

Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a maximum speed of 832Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is dependent on the line speed.

17.3.2.2 Sustained Cell Rate (SCR)

Sustained Cell Rate (SCR) is the mean cell rate of each bursty traffic source. It specifies the maximum average rate at which cells can be sent over the virtual connection. SCR may not be greater than the PCR.

17.3.2.3 Maximum Burst Size (MBS)

Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again. At this time, more cells (up to the MBS) can be sent at the PCR again.

Note: If the PCR, SCR or MBS is set to the default of "0", the system will assign a maximum value that correlates to your upstream line rate.

The following figure illustrates the relationship between PCR, SCR and MBS.

Figure 67 PCR, SCR and MBS in Traffic Shaping

17.3.2.4 Cell Delay Variation Tolerance (CDVT)

Cell Delay Variation Tolerance (CDVT) is the accepted tolerance of the difference between a cell's transfer delay and the expected transfer delay. CDVT controls the time scale over which the PCR is enforced. CDVT is used to determine if a cell arrived too early in relation to PCR.

17.3.2.5 Burst Tolerance (BT)

Burst Tolerance (BT) is the maximum number of cells that the port is guaranteed to handle without any discards. BT controls the time scale over which the SCR is enforced. BT is used to determine if a cell arrived too early in relation to SCR. Use this formula to calculate BT: (MBS - 1) x (1 / SCR - 1 / PCR) = BT.

17.3.2.6 Theoretical Arrival Time (TAT)

The Theoretical Arrival Time (TAT) is when the next cell (in an ATM connection's stream of cells) is expected to arrive. TAT is calculated based on the PCR or SCR.

The following figure illustrates the relationship between TAT, CDVT and BT. If a cell arrives at time A, then according to PCR or SCR, the next cell is expected to arrive at time B. If the next cell arrives earlier than time C, it is discarded or tagged for not complying with the TAT. Time C is calculated based on the CDVT or BT.

Figure 68 TAT, CDVT and BT in Traffic Shaping

17.4 Upstream Policing

Upstream policing is an agreement between the carrier and the subscriber to regulate the average rate and fluctuations of data transmission coming from the subscriber's device to the IES-1248.

Note: Upstream policing controls incoming (upstream) traffic, not outgoing (downstream).

The ATM traffic classes and parameters are identical with downstream shaping.

Upstream policing can control the upstream incoming traffic rate on specific PVCs. Upstream ATM cell traffic that violates the policing profile will be discarded. Traffic shaping must also be enabled on the subscriber's device in order to use upstream policing. If a subscriber attempts to enlarge his device's PVC shaping parameters in order to get more upstream traffic bandwidth, it will violate the IES-1248's upstream policing profile and the traffic will be discarded. Operators can use this feature to prevent subscribers from changing their device settings.

Note: Traffic shaping must also be enabled on the subscriber's device in order to use upstream policing.

Note that since the IES-1248 uses ATM QoS, if the subscriber device's upstream shaping rate is larger than the IES-1248's upstream policing rate, some ATM cells will be discarded. In the worst case, none of the Ethernet packets from the CPE will be able to be reassembled from AAL5, so no packets from the subscriber's device can be received by the IES-1248.

The upstream policing feature can be enabled/disabled per PVC. No matter which ATM traffic class is used for the PVC's upstream traffic (CBR, VBR, or UBR), the IES-1248 will drop any upstream traffic that violates the specified ATM VC profile.

17.7 IGMP Filtering

With the IGMP filtering feature, you can limit the multicast channel number of IGMP groups a subscriber on a port can join. This allows you to control the distribution of multicast services (such as content information distribution) based on service plans and types of subscription.

You can set the device to filter the multicast group join reports on a per-port basis by configuring an IGMP filtering profile and associating the profile to a port.

17.8 IGMP Filter Profile Screen

You can use the IGMP filter profiles to control access to a service that uses a specific multicast group (like a SIP server for example). Configure an IGMP filter profile that allows access to that multicast group. Then assign the IGMP filter profile to ADSL ports that are allowed to use the service.

The DEFVAL IGMP filter profile is assigned to all of the ADSL ports by default. It allows a port to join all multicast IP addresses (224.0.0.0~239.255.255.255). If you want to allow an ADSL subscriber access to only specific IGMP multicast groups, use the IGMP Filter Profile screen to configure a different profile and then assign it to the subscriber's ADSL port in the XDSL Port Setting screen (see Section 16.7.1 on page 123).

To open this screen, click Basic Setting, xDSL Profiles Setup, IGMP Filter Profile.

The top of the screen displays the configured IGMP filter profiles. Use the bottom part of the screen (with the Add and Cancel buttons) to add or edit alarm profiles.

18.3 xDSL Line Data Screen

This screen displays an ADSL port's line bit allocation.

Discrete Multi-Tone (DMT) modulation divides up a line's bandwidth into tones. This screen displays the number of bits transmitted for each tone. This can be used to determine the quality of the connection, whether a given sub-carrier loop has sufficient margins to support ADSL transmission rates, and possibly to determine whether certain specific types of interference or line attenuation exist. See the ITU-T G.992.1 recommendation for more information on DMT.

The better (or shorter) the line, the higher the number of bits transmitted for a DMT tone. The maximum number of bits that can be transmitted per DMT tone is 15.

CHAPTER 19

VLAN

This chapter shows you how to configure IEEE 802.1Q tagged VLANs.

19.1 Introduction to VLANs

A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Devices on a logical network belong to one group. A device can belong to more than one group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same group(s); the traffic must first go through a router.

In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security among the subscribers. When properly configured, VLAN prevents one subscriber from accessing the network resources of another on the same LAN, thus a user will not see the printers and hard disks of another user in the same building.

VLAN also increases network performance by limiting broadcasts to a smaller and more manageable logical broadcast domain. In traditional switched environments, all broadcast packets go to each and every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain.

Note that a VLAN is unidirectional, it only governs outgoing traffic.

19.2 Introduction to IEEE 802.1Q Tagged VLAN

Tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a frame across bridges - they are not confined to the device on which they were created. The VLANs can be created statically by hand or configured dynamically using GVRP.2 The VLAN ID associates a frame with a specific VLAN and provides the information that devices need to process the frame across the network. A tagged frame is four bytes longer than an untagged frame and contains two bytes of TPID (Tag Protocol Identifier, residing within the type/length field of the Ethernet frame) and two bytes of TCI (Tag Control Information, starts after the source address field of the Ethernet frame).

The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet switches. If a frame received at an Ethernet port has a CFI set to 1, then that frame should not be forwarded as it is to an untagged port. The remaining twelve bits define the VLAN ID, giving a possible maximum number of 4,096 (212) VLANs. Note that user priority and VLAN

ID are independent of each other. A frame with VID (VLAN Identifier) of null (0) is called a priority frame, meaning that only the priority level is significant and the default VID of the ingress port is given as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and value 4095 (FFF) is reserved, so the maximum possible VLAN configurations are 4,094.

TPID 2 Bytes

User Priority 3 Bits

CFI 1 Bit

VLAN ID 12 bits

The IES-1248 handles up to 4094 VLANs (VIDs 1-4094). The device accepts incoming frames with VIDs 1-4094.

19.2.1 Forwarding Tagged and Untagged Frames

Each port on the device is capable of passing tagged or untagged frames. To forward a frame from an 802.1Q VLAN-aware switch to an 802.1Q VLAN-unaware switch, the IES-1248 first decides where to forward the frame and then strips off the VLAN tag. To forward a frame from an 802.1Q VLAN-unaware switch to an 802.1Q VLAN-aware switch, the IES-1248 first decides where to forward the frame, and then inserts a VLAN tag reflecting the ingress port's default VID. The default PVID is VLAN 1 for all ports, but this can be changed.

The egress (outgoing) port(s) of a frame is determined on the combination of the destination MAC address and the VID of the frame. For a unicast frame, the egress port (based on the destination MAC address) must be a member of the VID, also; otherwise, the frame is blocked. For a broadcast frame, it is duplicated only on ports (except the ingress port itself) that are members of the VID, thus confining the broadcast to a specific domain.

Whether to tag an outgoing frame depends on the setting of the egress port on a per-VLAN, per-port basis (recall that a port can belong to multiple VLANs). If the tagging on the egress port is enabled for the VID of a frame, then the frame is transmitted as a tagged frame; otherwise, it is transmitted as an untagged frame.

CHAPTER 20 IGMP

This chapter describes the IGMP screens.

20.1 IGMP

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1 recipient) or Broadcast (1 sender to everybody on the network). Multicast delivers IP packets to just a group of hosts on the network.

IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a multicast group - it is not used to carry user data. See RFC 1112 and RFC 2236 for information on IGMP versions 1 and 2, respectively.

20.2 IP Multicast Addresses

In IPv4, a multicast address allows a device to send packets to a specific group of hosts (multicast group) in a different sub-network. A multicast IP address represents a traffic receiving group, not individual receiving devices. IP addresses in the Class D range (224.0.0.0 to 239.255.255.255) are used for IP multicasting. Certain IP multicast numbers are reserved by IANA for special purposes (see the IANA web site for more information).

20.2.1 IGMP Snooping

A layer-2 switch can passively snoop on IGMP Query, Report and Leave (IGMP version 2) packets transferred between IP multicast routers/switches and IP multicast hosts to learn the IP multicast group membership. It checks IGMP packets passing through it, picks out the group registration information, and configures multicasting accordingly. IGMP snooping allows the IES-1248 to learn multicast groups without you having to manually configure them.

The IES-1248 forwards multicast traffic destined for multicast groups (that it has learned from IGMP snooping or that you have manually configured) to ports that are members of that group. The IES-1248 discards multicast traffic destined for multicast groups that it does not know. IGMP snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through your device.

20.2.2 IGMP Proxy

To allow better network performance, you can use IGMP proxy instead of a multicast routing protocol in a simple tree network topology.

In IGMP proxy, an upstream interface is the port that is closer to the source (or the root of the multicast tree) and is able to receive multicast traffic. There should only be one upstream interface (also known as the query port) for one query VLAN on the IES-1248. A downstream interface is a port that connects to a host (such as a computer).

The following figure shows a network example where A is the multicast source while computers 1, 2 and 3 are the receivers. In the figure A is connected to the upstream interface and 1, 2 and 3 are connected to the downstream interface.

Figure 79 IGMP Proxy Network Example

The IES-1248 will not respond to IGMP join and leave messages on the upstream interface. The IES-1248 only responds to IGMP query messages on the upstream interface. The IES-1248 sends IGMP query messages to the hosts that are members of the query VLAN.

The IES-1248 only sends an IGMP leave messages via the upstream interface when the last host leaves a multicast group.

In daisychain mode, Ethernet interface 1 is set as the upstream interface and Ethernet interface 2 and the DSL ports are set as downstream interfaces.

20.7 IGMP Count Screen

Use this screen to limit the number of IGMP groups a subscriber on a port can join. This allows you to control the distribution of multicast services (such as content information distribution) based on service plans and types of subscription.

IGMP count is useful for ensuring the service quality of high bandwidth services like video or Internet Protocol television (IPTV). IGMP count can limit how many channels (IGMP groups) the subscriber connected to a DSL port can use at a time. If each channel requires 4~5 Mbps of download bandwidth, and the subscriber's connection supports 11 Mbps, you can use IGMP count to limit the subscriber to using just 2 channels at a time. This also effectively limits the subscriber to using only two IPTVs with the DSL connection.

CHAPTER 22

Multicast VLAN

This chapter describes the Multicast VLAN screens.

22.1 Multicast VLAN Overview

Multicast VLAN allows one single multicast VLAN to be shared among different subscriber VLANs on the network. This improves bandwidth utilization by reducing multicast traffic in the subscriber VLANs and simplifies multicast group management.

When the IES-1248 forwards traffic to a subscriber port, it tries to forward traffic to a normal PVC with the same VLAN ID. If this PVC does not exist, the IES-1248 uses the super channel instead. This applies to all downstream traffic, not just multicast traffic.

It is suggested to use a super channel for multicast VLAN. If a normal PVC is used and the multicast VLAN ID is not the same as the PVC's VID, the IES-1248 does not forward traffic to this PVC even if the subscriber's port has joined the multicast VLAN.

Since the IES-1248 might change the subscriber's VLAN ID to the multicast VLAN ID, both the subscriber's port and the Ethernet port should join the multicast VLAN.

PPPoE Pass through	Point-to-Point Protocol over Ethernet relies on PPP and Ethernet. It is a specification for connecting the users on an Ethernet to the Internet through a common broadband medium, such as a single DSL line, wireless device or cable modem.
IP Pass through	Internet Protocol. The underlying protocol for routing packets on the Internet and other TCP/IP-based networks.
ARP Pass through	Address Resolution Protocol is a protocol for mapping an Internet Protocol address (IP address) to a physical computer address that is recognized in the local network.
NetBios Pass through	NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that enable a computer to find other computers.
DHCP Pass through	Dynamic Host Configuration Protocol automatically assigns IP addresses to clients when they log on. DHCP centralizes IP address management on central computers that run the DHCP server program. DHCP leases addresses, for a period of time, which means that past addresses are "recycled" and made available for future reassignment to other systems.
EAPOL Pass through	EAP (Extensible Authentication Protocol, RFC 2486) over LAN. EAP is used with IEEE 802.1x to allow additional authentication methods (besides RADIUS) to be deployed with no changes to the access point or the wireless clients.
IGMP Pass through	Internet Group Multicast Protocol is used when sending packets to a specific group of hosts.

CHAPTER 25

Spanning Tree Protocol

This chapter introduces the Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP).

25.1 RSTP and STP

RSTP adds rapid reconfiguration capability to STP. The IES-1248 supports RSTP and the earlier STP. RSTP and STP detect and break network loops and provide backup links between switches, bridges or routers. They allow a device to interact with other RSTP or STP-aware devices in your network to ensure that only one path exists between any two stations on the network. The Integrated Ethernet Switch uses RSTP by default but can still operate with STP switches (although without RSTP's benefits).

The root bridge is the base of the spanning tree; it is the bridge with the lowest identifier value (MAC address). Path cost is the cost of transmitting a frame onto a LAN through that port. It is assigned according to the speed of the link to which a port is attached. The slower the media, the higher the cost, as illustrated in the following table.

Table 48 Path Cost

	LINK SPEED	RECOMMENDED VALUE	RECOMMENDED RANGE	ALLOWED RANGE
Path Cost	4Mbps	250	100 to 1000	1 to 65535
Path Cost	10Mbps	100	50 to 600	1 to 65535
Path Cost	16Mbps	62	40 to 400	1 to 65535
Path Cost	100Mbps	19	10 to 60	1 to 65535
Path Cost	1Gbps	4	3 to 10	1 to 65535
Path Cost	10Gbps	2	1 to 5	1 to 65535

On each bridge, the root port is the port through which this bridge communicates with the root. It is the port on this Integrated Ethernet Switch with the lowest path cost to the root (the root path cost). If there is no root port, then this Integrated Ethernet Switch has been accepted as the root bridge of the spanning tree network.

For each LAN segment, a designated bridge is selected. This bridge has the lowest cost to the root among the bridges connected to the LAN.

After a bridge determines the lowest cost-spanning tree with RSTP, it enables the root port and the ports that are the designated ports for the connected LANs, and disables all other ports that participate in RSTP. Network packets are therefore only forwarded between enabled ports, eliminating any possible network loops.

Figure 93 STP Root Ports and Designated Ports

RSTP-aware devices exchange Bridge Protocol Data Units (BPDUs) periodically. When the bridged LAN topology changes, a new spanning tree is constructed.

In RSTP, the devices send BPDUs every Hello Time. If an RSTP-aware device does not get a Hello BPDU after three Hello Times pass (or the Max Age), the device assumes that the link to the neighboring bridge is down. This device then initiates negotiations with other devices to reconfigure the network to re-establish a valid network topology.

In STP, once a stable network topology has been established, all devices listen for Hello BPDUs transmitted from the root bridge. If an STP-aware device does not get a Hello BPDU after a predefined interval (Max Age), the device assumes that the link to the root bridge is down. This device then initiates negotiations with other devices to reconfigure the network to re-establish a valid network topology.

RSTP assigns three port states to eliminate packet looping while STP assigns five (see Table 49 on page 188). A device port is not allowed to go directly from blocking state to forwarding state so as to eliminate transient loops.

Table 49 RSTP Port States

RSTP PORT STATE	STP PORT STATE	DESCRIPTION
Discarding	Disabled	RSTP or STP is disabled (default).
Discarding	Blocking	In RSTP, BPDUs are discarded. In STP, only configuration and management BPDUs are received and processed.
Discarding	Listening	In RSTP, BPDUs are discarded. In STP, all BPDUs are received and processed.
Learning	Learning	All BPDUs are received and processed. Information frames are submitted to the learning process but not forwarded.
Forwarding	Forwarding	All BPDUs are received and processed. All information frames are received and forwarded.

See the IEEE 802.1w standard for more information on RSTP. See the IEEE 802.1D standard for more information on STP.

Spanning Tree Protocol	This field displays On if STP is activated. Otherwise, it displays Off.
Bridge Status	If STP is activated, the following fields appear. If STP is not activated, Disabled appears.
Our bridge ID	This is the unique identifier for this bridge, consisting of bridge priority plus MAC address. This ID is the same in Designated root ID if the IES-1248 is the root switch.
Designated root ID	This is the unique identifier for the root bridge, consisting of bridge priority plus MAC address. This ID is the same in Our bridge ID if the IES-1248 is the root switch.
Topology change times	This is the number of times the spanning tree has been reconfigured.
Time since change	This is the time since the spanning tree was last reconfigured.
Cost to root	This is the path cost from the root port on this switch to the root switch.
Root port ID	This is the priority and number of the port on the switch through which this switch must communicate with the root of the Spanning Tree. "0x0000" displays when this device is the root switch.
Root max age (second)	This is the maximum time (in seconds) the root switch can wait without receiving a configuration message before attempting to reconfigure.
Root hello time (second)	This is the time interval (in seconds) at which the root switch transmits a configuration message. The root bridge determines Hello Time, Max Age and Forwarding Delay.
Root forward delay (second)	This is the time (in seconds) the root switch will wait before changing states (that is, listening to learning to forwarding).
Max age (second)	This is the maximum time (in seconds) the IES-1248 can wait without receiving a configuration message before attempting to reconfigure.
Hello time (second)	This is the time interval (in seconds) at which the IES-1248 transmits a configuration message. The root bridge determines Hello Time, Max Age and Forwarding Delay.
Forward delay (second)	This is the time (in seconds) the IES-1248 will wait before changing states (that is, listening to learning to forwarding).
Port Status	This identifies the IES-1248's ports that support the use of STP. If STP is activated, the following fields appear. If STP is not activated, Disabled appears.
State	This field displays the port's RSTP (or STP) state. With RSTP, the state can be discarding, learning or forwarding. With STP, the state can be disabled, blocking, listening, learning, or forwarding. Disabled appears when RSTP has not been turned on for the individual port or the whole device.

LABEL	DESCRIPTION
STP Status	Click STP Status to display the IES-1248's STP status (see Section 25.2 on page 189).
Active	Select this check box to turn on RSTP.Note: It is recommended that you only use STP when you use the IES-1248 in standalone mode with a network topology that has loops.
Bridge Priority	Bridge priority is used in determining the root switch, root port and designated port. The switch with the highest priority (lowest numeric value) becomes the STP root switch. If all switches have the same priority, the switch with the lowest MAC address will then become the root switch. The allowed range is 0 to 61440. The lower the numeric value you assign, the higher the priority for this bridge. Bridge Priority determines the root bridge, which in turn determines Hello Time, Max Age and Forwarding Delay.
Hello Time	This is the time interval in seconds between BPDU (Bridge Protocol Data Units) configuration message generations by the root switch. The allowed range is 1 to 10 seconds.
MAX Age	This is the maximum time (in seconds) a switch can wait without receiving a BPDU before attempting to reconfigure. All switch ports (except for designated ports) should receive BPDUs at regular intervals. Any port that ages out STP information (provided in the last BPDU) becomes the designated port for the attached LAN. If it is a root port, a new root port is selected from among the switch ports attached to the network. The allowed range is 6 to 40 seconds.
Forwarding Delay	This is the maximum time (in seconds) a switch will wait before changing states. This delay is required because every switch must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that would make it return to a blocking state; otherwise, temporary data loops might result. The allowed range is 4 to 30 seconds.As a general rule:Note: 2* (Forward Delay - 1) >= Max Age >= 2* (Hello Time + 1)
Port	This field identifies the Ethernet port.
Active	Select this check box to activate STP on this port.
Priority	Configure the priority for each port here.Priority decides which port should be disabled when more than one port forms a loop in a switch. Ports with a higher priority numeric value are disabled first. The allowed range is between 0 and 255 and default value is 128.
Path Cost	Path cost is the cost of transmitting a frame on to a LAN through that port. It is assigned according to the speed of the bridge. The slower the media, the higher the cost.
Apply	Click Apply to save your changes to the IES-1248's volatile memory. The IES-1248 loses these changes if it is turned off or loses power, so use the Config Save link on the navigation panel to save your changes to the non-volatile memory when you are done configuring.

CHAPTER 26 Port Authentication

This chapter describes the 802.1x authentication method and RADIUS server connection setup.

26.1 Introduction to Authentication

IEEE 802.1x is an extended authentication protocol³ that allows support of RADIUS (Remote Authentication Dial In User Service, RFC 2138, 2139) for centralized user profile management on a network RADIUS server.

26.1.1 RADIUS

RADIUS (Remote Authentication Dial-In User Service) authentication is a popular protocol used to authenticate users by means of an external server instead of (or in addition to) an internal device user database that is limited to the memory capacity of the device. In essence, RADIUS authentication allows you to validate an unlimited number of users from a central location.

CHAPTER 28 DHCP Relay

This chapter shows you how to set up DHCP relays for each VLAN.

28.1 DHCP Relay

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain TCP/IP configuration at start-up from a DHCP server. You can configure the IES-1248 to relay DHCP requests to one or more DHCP servers and the server's responses back to the clients. You can specify default DHCP servers for all VLAN, and you can specify DHCP servers for each VLAN.

28.2 DHCP Relay Agent Information Option (Option 82)

The IES-1248 can add information to DHCP requests that it relays to a DHCP server. This helps provide authentication about the source of the requests. You can also specify additional information for the IES-1248 to add to the DHCP requests that it relays to the DHCP server. Please see RFC 3046 for more details.

28.2.1 DHCP Relay Agent Circuit ID and Remote ID Sub-option Formats

The DHCP relay agent information feature adds an Agent Information field to the option 82 field of the DHCP headers of DHCP request frames that the IES-1248 relays to a DHCP server. The Agent Information field that the IES-1248 adds contains an "Agent Circuit-ID suboption" that includes the port number, VLAN ID and optional information about the port where the DHCP request was received.

The following figure shows the format of the Agent Circuit ID sub-option. The 1 in the first field identifies this as an Agent Circuit ID sub-option. The length N gives the total number of octets in the Agent Information Field. If the configuration request was received on a DSL port, a 2-byte Port No field specifies the ingress port number (the first byte is always 0, the second byte is in hexadecimal format). The next field is 2 bytes and displays the DHCP request packet's VLAN ID. The last field (A) can range from 0 to 24 bytes and is optional information (that you specify) about this relay agent.

The Agent Information field that the IES-1248 adds also contains an "Agent Remote-ID suboption" of information that you specify.

The following figure shows the format of the Agent Remote ID sub-option. The 2 in the first field identifies this as an Agent Remote ID sub-option. The length N gives the total number of octets in the Agent Information Field. Then there is the number of the port (in plain text format) upon which the DHCP client request was received. The next field (B in the figure) is 0 to 23 bytes of optional information that you specify. This is followed by the name and telephone number configured for the ADSL port. The port number, optional information (B in the figure), ADSL name and ADSL telephone number fields are separated by forward slashes.

CHAPTER 29 DHCP Snoop

This chapter shows you how to set up DHCP snooping settings on the subscriber ports.

29.1 DHCP Snoop Overview

DHCP snooping prevents clients from assigning their own IP addresses. The IES-1248 can store every (ADSL port, MAC address, IP address) tuple offered by the DHCP server. Then, it only forwards packets from clients whose MAC address and IP address are recorded. Packets from unknown IP addresses are dropped.

CHAPTER 30

2684 Routed Mode

This chapter shows you how to set up 2684 routed mode service.

30.1 2684 Routed Mode

Use the 2684 (formerly 1483) routed mode to have the IES-1248 add MAC address headers to 2684 routed mode traffic from a PVC that connects to a subscriber device that uses 2684 routed mode. You also specify the gateway to which the IES-1248 sends the traffic and the VLAN ID tag to add. See RFC-2684 for details on routed mode traffic carried over AAL type 5 over ATM.

• Use the 2684 Routed PVC Screen to configure PVCs for 2684 routed mode traffic.
• Use the 2684 Routed Domain Screen to configure domains for 2684 routed mode traffic. The domain is the range of IP addresses behind the subscriber's device (the CPE or Customer Premises Equipment). This includes the CPE device's LAN IP addresses and the IP addresses of the LAN computers.
• Use the RPVC Arp Proxy Screen to view the Address Resolution Protocol table of IP addresses of CPE devices using 2684 routed mode and configure how long the device is to store them.
• Use the 2684 Routed Gateway Screen to configure gateway settings.
• For upstream traffic: Since the subscriber's device will not send out a MAC address, after the IES-1248 reassembles the Ethernet packets from the AAL5 ATM cells, the IES-1248 will append the routed mode gateway's MAC address and the IES-1248's MAC address as the destination/source MAC address.
• For downstream traffic: When the IES-1248 sees the destination IP address is specified in the RPVC (or RPVC domain), the IES-1248 will strip out the MAC header and send them to the corresponding RPVC.

30.1.1 2684 Routed Mode Example

The following figure shows an example 2684 routed mode set up. The gateway server uses IP address 192.168.10.102 and is in VLAN 1. The IES-1248 uses IP address 192.168.20.101. The subscriber's device (the CPE) is connected to DSL port 1 on the IES-1248 and the 2684 routed mode traffic is to use the PVC identified by VPI 8 and VCI 35. The CPE device's WAN IP address is 192.168.10.200. The routed domain is the LAN IP addresses behind the CPE device. The CPE device's LAN IP address is 10.10.10.10 and the LAN computer's IP address is 10.10.10.1. This includes the CPE device's LAN IP addresses and the IP addresses of the LAN computers.

Figure 107 2684 Routed Mode Example

Note the following.

• The CPE device's WAN IP (192.168.10.200 in this example) must be in the same subnet as the gateway's IP address (192.168.10.102 in this example).
• The IES-1248's management IP address can be any IP address, it doesn't have any relationship to the WAN IP address or routed gateway IP address.
• The IES-1248's management IP address should not be in the same subnet as the one defined by the WAN IP address and netmask of the subscriber's device. It is suggested that you set the netmask of the subscriber's WAN IP address to 32 to avoid this problem.
• The IES-1248's management IP address should not be in the same subnet range of any RPVC and RPVC domain. It will make the IES-1248 confused if the IES-1248 receives a packet with this IP as destination IP.
• The IES-1248's management IP address also should not be in the same subnet as the one defined by the LAN IP address and netmask of the subscriber's device. Make sure you assign the IP addresses properly.
• In general deployment, the computer must set the CPE device's LAN IP address (10.10.10.10 in this example) as its default gateway.
• The subnet range of any RPVC and RPVC domain must be unique.

CHAPTER 31 PPPoA to PPPoE

This chapter shows you how to set up the IES-1248 to convert PPPoA frames to PPPoE traffic and vice versa.

31.1 PPPoA to PPPoE Overview

Before migrating to an Ethernet infrastructure, a broadband network might consist of PPPoA connections between the CPE devices and the DSLAM and PPPoE connections from the DSLAM to the Broadband Remote Access Server (BRAS). The following figure shows a network example.

Figure 112 Mixed PPPoA-to-PPPoe Broadband Network Example

In order to allow communication between the end points (the CPE devices and the BRAS), you need to configure the DSLAM (the IES-1248) to translate PPPoA frames to PPPoE packets and vise versa.

When PPPoA packets are received from the CPE, the ATM headers are removed and the IES-1248 adds PPPoE and Ethernet headers before sending the packets to the BRAS. When the IES-1248 receives PPPoE packets from the BRAS, PPPoE and Ethernet headers are stripped and necessary PVC information (such as encapsulation type) is added before forwarding to the designated CPE.

31.2 PPPoA to PPPoE Screen

Use this screen to set up PPPoA to PPPoE conversions on each port. This conversion is set up by creating a PAE PVC. See Chapter 16 on page 119 for background information about creating PVCs. To open this screen, click Advanced Application, PPPoA to PPPoE.

CHAPTER 33 TLS PVC

This chapter shows you how to set up Transparent LAN Service (VLAN stacking, Q-in-Q) on each port.

33.1 Transparent LAN Service (TLS) Overview

Transparent LAN Service (also known as VLAN stacking or Q-in-Q) allows a service provider to distinguish multiple customers VLANs, even those with the same (customer-assigned) VLAN ID, within its network.

Use TLS to add an outer VLAN tag to the inner IEEE 802.1Q tagged frames that enter the network. By tagging the tagged frames ("double-tagged" frames), the service provider can manage up to 4,094 VLAN groups with each group containing up to 4,094 customer VLANs. This allows a service provider to provide different services, based on specific VLANs, for many different customers.

A service provider's customers may require a range of VLANs to handle multiple applications. A service provider's customers can assign their own inner VLAN tags to traffic. The service provider can assign an outer VLAN tag for each customer. Therefore, there is no VLAN tag overlap among customers, so traffic from different customers is kept separate.

Before the IES-1248 sends the frames from the customers, the VLAN ID is added to the frames. When packets intended for specific customers are received on the IES-1248, the outer VLAN tag is removed before the traffic is sent.

33.1.1 TLS Network Example

In the following example figure, both A and B are Service Provider's Network (SPN) customers with VPN tunnels between their head offices and branch offices, respectively. Both have an identical VLAN tag for their VLAN group. The service provider can separate these two VLANs within its network by adding tag 37 to distinguish customer A and tag 48 to distinguish customer B at edge device 1 and then stripping those tags at edge device 2 as the data frames leave the network.

CHAPTER 34 ACL

This chapter shows you how to set up ACL profiles on each port.

34.1 Access Control Logic (ACL) Overview

An ACL (Access Control Logic) profile allows the IES-1248 to classify and perform actions on the upstream traffic. Each ACL profile consists of a rule and an action, and you assign ACL profiles to PVCs.

34.1.1 ACL Profile Rules

Each ACL profile uses one of 14 rules to classify upstream traffic. These rules are listed below by rule number.

1 etype vlan
2 etype smac
3 etype dmac
4 vlan smac
5 vlan dmac
6 smac dmac
7 vlan priority
8 etype
9 vlan
10smac
11dmac
12priority
13protocol
14{srcip 一 i p > / < m a s k > {|dstip 一 i p > / < m a s k > {|tos 一 s t o s > |etos> {|s r c p o r t } {dstport }}}

The input values for these values have the following ranges.

If you apply multiple profiles to a PVC, the IES-1248 checks the profiles by rule number. The lower the rule number, the higher the priority the rule (and profile) has. For example, there are two ACL profiles assigned to a PVC. Profile1 is for VLAN ID 100 (rule number 9) traffic, and Profile2 is for IEEE 802.1p priority 0 traffic (rule number 12). The IES-1248 checks Profile1 first. If the traffic is VLAN ID 100, the IES-1248 follows the action in Profile1 and does not check Profile2. You cannot assign profiles that have the same rule numbers to the same PVC.

34.1.2 ACL Profile Actions

The IES-1248 can perform the following actions after it classifies upstream traffic.

• rate < rate>: change the rate to the specified value (1~6535 kbps)
• rvlan : change the VLAN ID to the specified value (1~4094)
• rpri : change the IEEE 802.1p priority to the specified value (0~7)
• deny: do not forward the packet

The IES-1248 can apply more than one action to a packet, unless you select deny.

If you select the rvlan action, the IES-1248 replaces the VLAN ID before it compares the VLAN ID of the packet to the VID of the PVC. As a result, it is suggested that you replace VLAN ID on super channels, not normal PVC, since super channels accept any tagged traffic. If you replace the VLAN ID for a normal PVC, the IES-1248 drops the traffic because the new VLAN ID does not match the VID of the PVC. This is illustrated in the following scenario.

There is a normal PVC, and its PVID is 900. You create an ACL rule to replace the VLAN ID with 901. Initially, the traffic for the PVC belongs to VLAN 900. Then, the IES-1248 checks the ACL rule and changes the traffic to VLAN 901. When the IES-1248 finally compares the VLAN ID of the traffic (901) to the VID of the PVC (900), the IES-1248 drops the packets because they do not match.

37.3 SNMP

Simple Network Management Protocol is a protocol used for exchanging management information between network devices. SNMP is a member of TCP/IP protocol suite. A manager station can manage and monitor the IES-1248 through the network via SNMP version one (SNMPv1) and/or SNMP version 2c. The next figure illustrates an SNMP management operation. SNMP is only available if TCP/IP is configured.

Figure 125 SNMP Management Model

An SNMP managed network consists of two main components: agents and a manager.

An agent is a management software module that resides in a managed device (the IES-1248). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices.

The managed devices contain object variables/managed objects that define each piece of information to be collected about a device. Examples of variables include such as number of packets received, node port status etc. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects.

SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations:

Table 74 SNMP Commands

COMMAND	DESCRIPTION
Get	Allows the manager to retrieve an object variable from the agent.
GetNext	Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations.
Set	Allows the manager to set values for object variables within an agent.
Trap	Used by the agent to inform the manager of some events.

37.3.1 Supported MIBs

MIBs let administrators collect statistics and monitor status and performance. The IES-1248 supports the following MIBs:

• MIB II IF MIB and ADSL line MIB (RFC-2662)
  SNMP MIB II (RFC-1215)
  BRIDGE MIB: FDB status

The IES-1248 can also respond with specific data from the DSLAM private MIBs:

• dslam.mib
• dslam-AS-ATM.mib
• dslam-AS.mib
• dslam-AESCommon.mib
• dslam-iesCommon.mib
• ies1248.mib

37.3.2 SNMP Traps

The IES-1248 can send the following SNMP traps to an SNMP manager when an event occurs. ATUC refers to the downstream channel (for traffic going from the IES-1248 to the subscriber). ATUR refers to the upstream channel (for traffic coming from the subscriber to the IES-1248).

CHAPTER 38

Static Routing

This chapter shows you how to configure the static routing function.

Static routes tell the IES-1248 how to forward the IES-1248's own IP traffic when you configure the TCP/IP parameters manually. This is generally useful for allowing management of the device from a device with an IP address on a different subnet from that of the device's IP address (remote management).

To open this screen, click Routing Protocol, Static Routing.

CHAPTER 42 MAC Table

This chapter introduces the MAC Table.

42.1 Introduction to MAC Table

The MAC table lists device MAC addresses that are dynamically learned by the IES-1248. The table shows the following for each MAC address: the port upon which Ethernet frames were received from the device, to which VLAN groups the device belongs (if any) and to which channel it is connected (for devices connected to DSL ports).

The device uses the MAC table to determine how to forward frames. See the following figure.

Figure 141 MAC Table Filtering Flowchart

1 The device examines a received frame and learns the port on which this source MAC address came.
2 The device checks to see if the frame's destination MAC address matches a source MAC address already learned in the MAC table.
- If the device has already learned the port for this MAC address, then it forwards the frame to that port.
- If the device has not already learned the port for this MAC address, then the frame is flooded to all ports. Too much port flooding leads to network congestion.

• If the device has already learned the port for this MAC address, but the destination port is the same as the port it came in on, then it filters the frame.

42.2 MAC Table Screen

To open this screen, click Management, MAC Table.

CHAPTER 43 ARP Table

This chapter describes the ARP Table.

43.1 Introduction to ARP Table

Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address, also known as a Media Access Control or MAC address, on the local area network.

An IP (version 4) address is 32 bits long. In an Ethernet LAN, MAC addresses are 48 bits long. The ARP Table maintains an association between each MAC address and its corresponding IP address.

43.1.1 How ARP Works

When an incoming packet destined for a host device on a local area network arrives at the device, the device's ARP program looks in the ARP Table and, if it finds the address, sends it to the device.

If no entry is found for the IP address, ARP broadcasts the request to all the devices on the LAN. The device fills in its own MAC and IP address in the sender address fields, and puts the known IP address of the target in the target IP address field. In addition, the device puts all ones in the target MAC field (FF.FF.FF.FF.FF.FF is the Ethernet broadcast address). The replying device (which is either the IP address of the device being sought or the router that knows the way) replaces the broadcast address with the target's MAC address, swaps the sender and target pairs, and unicast the answer directly back to the requesting machine. ARP updates the ARP Table for future reference and then sends the packet to the MAC address that replied.

43.2 ARP Table Screen

The ARP table can hold up to 500 entries.

To open this screen, click Management, ARP Table.

CHAPTER 44 Commands

This chapter introduces the command line interface and lists the available commands.

44.1 Command Line Interface Overview

Note: See the previous chapters for background information on features configurable by the web configurator. The web configurator is the preferred configuration tool.

You can use text command lines for software configuration. The rules of the commands are listed next.

1 The command keywords are in courier new font.
2 Commands can be abbreviated to the smallest unique string that differentiates the command. For example, the "system date" command could be abbreviated to "sy d".
3 The optional fields in a command are enclosed in square brackets []. For instance, config [save] means that the save field is optional.
4 "Command" refers to a command used in the command line interface (CI command).
5 The symbol means "or".

Note: Using commands not documented in the User's Guide can damage the unit and possibly render it unusable.

44.2 Command Privilege Levels

There is a high, middle or low privilege level for each command.

High privilege commands are only available to administrators with high privilege access. High privilege commands include things like creating administrator accounts, restarting the system and resetting the factory defaults. Administrators with high privilege access can use all commands including the lower privilege commands.

Administrators with middle privilege access can use middle or low privilege commands.

Administrators with the low privilege level are restricted to using only low privilege commands. Low privilege commands are read only.

44.3 Saving Your Configuration

Use the following command to save your configuration when you are done with a configuration session.

ras> config save

Note: Do not turn off your IES-1248 while saving your configuration.

This command saves all system configurations to nonvolatile memory. You must use this command to save any configuration changes that you make, otherwise the IES-1248 returns to its default settings when it is restarted. Save your changes after each configuration session.

Nonvolatile memory refers to the IES-1248's storage that remains even if the IES-1248's power is turned off. Run-time (memory) is lost when the IES-1248's power is turned off.

44.4 Commands

47.1.2 Enable Command

Syntax:

ras> switch dhcpprelay enable 

This command turns on the DHCP relay feature.

47.1.3 Disable Command

Syntax:

ras> switch dhcpprelay disable

This command turns off the DHCP relay feature.

47.1.4 Server Set Command

Syntax:

ras> switch dhcpprelay server set <vid> <primary-server> [<secondary-server>] 

where

<vid> = The ID of the VLAN served by the specified DHCP server(s). 

<primary- = The IP address of one DHCP server. server> 

<secondary- = The IP address of a second DHCP server. server> 

This command specifies the DHCP server(s) that serve the specified VLAN. The primary server is required; the secondary server is optional. The IES-1248 routes DHCP requests to the specified DHCP server(s) according to the relaymode. See Section 47.1.7 on page 307.

Use VLAN ID 0 to set up the default DHCP server(s) for all non-listed VLAN.

47.1.5 Server Delete Command

Syntax:

ras> switch dhcpprelay server delete <vid> [<primary-server>] 

where

<vid> = The ID of the VLAN served by the specified DHCP server(s). 

<primary- = The IP address of one DHCP server. server> 

This command deletes all information about DHCP servers for the specified VLAN.

Afterwards, the specified VLAN can uses the default DHCP server(s) set up for VLAN ID 0, if any.

47.1.6 Server Active Command

Syntax:

ras> switch dhcpprelay server active <vid> <active-server> 

where

<vid> = The ID of the VLAN served by the specified DHCP server(s). 

<active-server> = 1: The primary DHCP server is active. 

2: The secondary DHCP server is active. 

This command has no effect if the relaymode is both. If the relaymode is auto, this command specifies to which DHCP server (the primary one or the secondary one) the IES-1248 should relay DHCP requests for the selected VLAN.

47.1.7 Relaymode Command

Syntax:

ras> switch dhcpprelay relaymode <mode> 

where

<mode> = relay process mode; it controls to which DHCP server(s) the IES-1248 relays DHCP requests. 

auto - the IES-1248 relays DHCP requests to the active server for each VLAN

both - the IES-1248 relays DHCP requests to the primary and secondary server for each VLAN, regardless of which one is active

This command controls how the IES-1248 routes DHCP requests. The IES-1248 can route DHCP requests to the active DHCP server for the VLAN, or it can route DHCP requests to all DHCP servers set up for the VLAN.

This command adds the specified information for the relay agent.

47.4 DHCP Snoop Commands

Use these commands to configure or show DHCP snooping settings on the subscriber ports. The system gets the client MAC-IP address information (in the reply from a DHCP server) and stores it in the DHCP snooping table. The system only forwards packets from the clients whose MAC-IP address is in the DHCP snooping table. Packets from unknown IP address(es) are not forwarded (dropped). This feature prevents clients from assigning their own static IP addresses.

CHAPTER 48

IEEE 802.1Q Tagged VLAN

Commands

This chapter describes the IEEE 802.1Q Tagged VLAN commands.

48.1 Introduction to VLANs

See Chapter 19 on page 157 for more background information on VLANs.

48.2 IEEE 802.1Q Tagging Types

There are two kinds of tagging:

• Explicit Tagging

A VLAN identifier is added to the frame header that identifies the source VLAN.

• Implicit Tagging

The MAC (Media Access Control) number, the port or other information is used to identify the source of a VLAN frame.

The IEEE 802.1Q Tagged VLAN uses both explicit and implicit tagging.

It is important for the IES-1248 to determine what devices are VLAN-aware and VLAN-unaware so that it can decide whether to forward a tagged frame (to a VLAN-aware device) or first strip the tag from a frame and then forward it (to a VLAN-unaware device).

48.3 Filtering Databases

A filtering database stores and organizes VLAN registration information useful for switching frames to and from the IES-1248. A filtering database consists of static entries (Static VLAN or SVLAN table).

48.3.1 Static Entries (SVLAN Table)

Static entry registration information is added, modified and removed by administrators only.

48.4 IEEE VLAN1Q Tagged VLAN Configuration Commands

These switch commands allow you to configure and monitor the IEEE 802.1Q Tagged VLAN.

48.4.1 VLAN Port Show Command

Syntax:

ras> switch vlan portshow [portlist] 

where

[portlist] = You can specify a single port <1> , all ports <* or a list of ports <1,3,enet1> . You can also include a range of ports <1,5,610,enet1,enet2> .

This command displays the port's IEEE 802.1Q VLAN tag settings.

The following example shows the settings for ADSL port 1.

Figure 161 VLAN Port Show Command Example

ras> switch vlan portshow 3  
port pvid priorityframetype  
3 1 0 all 

48.4.2 VLAN PVID Command

Syntax:

ras> switch vlan pvid <portlist> <pvid> 

where

= You can specify a single port <1> , all ports <^*> or a list of ports <1,3,enet1> . You can also include a range of ports <1,5,610,enet1,enet2> .

<p> = The VLAN ID. Valid parameter range = [1 - 4094].</p> 

This command sets a default VLAN ID for all untagged packets that come in through the specified port.

The following example sets the default VID of port 1 to 200.

Figure 162 VLAN PVID Command Example

ras> switch vlan pvid 1 200 

48.4.3 VLAN Priority Command

Syntax:

ras> switch vlan priority <portlist> <priority> 

where

= You can specify a single port: <1> , all ports: <^*> , a list of ports: <1,3,enet1> , you can also include a range of ports: <1,5,610,enet1,enet2> .

<priority> = This is the priority value (0 to 7) to use for incoming frames with an IEEE 802.1Q VLAN tag. 

This command sets the priority of incoming frames with an IEEE 802.1Q VLAN tag.

The following example sets a priority of three for frames (with an IEEE 802.1Q VLAN tag) that come in on ADSL port 2.

Figure 163 VLAN CPU Set Command Example

ras> switch vlan priority 2 3 

48.4.4 VLAN Set Command

Syntax:

ras> switch vlan set <vid> <portlist>:<F<T|U>|X|N> [<portlist>:<F<T|U>|X> ...][name] 

where

<vid> = The VLAN ID [1 - 4094]. 

= You can specify a single port: <1> , all ports: <^*> , a list of ports: <1,3,enet1> , you can also include a range of ports: <1,5,610,enet1,enet2> .

< F < T|U > ) = The < F> stands for a fixed registrar administration control flag and registers a port # to the static VLAN table with vid>. For a fixed port, you also have to specify < T|U> ,the tag control flag. T has the device add an IEEE 802.1Q tag to frames going out through this port(s). U has the device send frames out through this port(s) without an IEEE 802.1Q tag.
|X|N> = This is the registrar administration control flag. X stands for forbidden and blocks a port # from joining the static VLAN table with vid>. N stands for normal and confirms registration of the port # to the static VLAN table with vid>. This is used in GVRP applications.
[name] = A name to identify the SVLAN entry.

This command adds or modifies an entry in the static VLAN table. Use the switch vlan show command to display your configuration. An example of a configuration is shown next.

48.4.4.1 Modify a Static VLAN Table Example

The following is an example of how to modify a static VLAN table.

Figure 164 Modifying the Static VLAN Example

ras> switch vlan set 2000 1:FU  
ras> switch vlan set 2001 2:FU 

48.4.4.2 Forwarding Process Example

Tagged Frames

1 First the IES-1248 checks the VLAN ID (VID) of tagged frames or assigns temporary VIDs to untagged frames (see Section 48.4.2 on page 314).
2 The IES-1248 checks the frame's source MAC address against the MAC filter.
3 The IES-1248 then checks the VID in a frame's tag against the SVLAN table.
4 The IES-1248 notes what the SVLAN table says (that is, the SVLAN tells the IES-1248 whether or not to forward a frame and if the forwarded frames should have a tag).
5 Frames might be dropped if they are sent to a CPE (customer premises equipment) DSL device that does not accept tagged frames.

Untagged Frames

1 An untagged frame comes in from the LAN.
2 The IES-1248 checks the frame's source MAC address against the MAC filter.
3 The IES-1248 checks the PVID table and assigns a VID and IEEE 802.1Q priority.
4 The IES-1248 ignores the port from which the frame came, because the IES-1248 does not send a frame to the port from which it came. The IES-1248 also does not forward frames to "forbidden" ports.
5 If after looking at the SVLAN, the IES-1248 does not have any ports to which it will send the frame, it drops the frame.

48.4.5 VLAN Frame Type Command

Syntax:

ras> switch vlanframetype <portlist> <all|tag> 

where

You can specify a single DSL port < 1> , all DSL ports <^*> or a list of DSL ports < 1,3> . You can also include a range of DSL ports < 1,5,6 10> .

= Use tag to have the specified port(s) accept only incoming Ethernet frames that have a VLAN tag.

Use all to have the specified port(s) accept both tagged and untagged incoming Ethernet frames.

This command sets the specified DSL ports to accept VLAN tagged Ethernet frames, or both tagged and untagged Ethernet frames.

Note: The IES-1248 accepts both tagged and untagged incoming frames on the Ethernet ports.

The following example sets the IES-1248 to accept only VLAN tagged Ethernet frames on DSL port 3.

Figure 165 VLAN Frame Type Command Example

ras> switch vlanframetype 3 tag 

48.4.6 VLAN CPU Show Command

Syntax:

ras> switch vlan cpu show 

This command displays the management VLAN (CPU). You can only use ports that are members of this management VLAN in order to manage the IES-1248.

The following example sets VLAN ID 2 to be the CPU (management) VLAN.

Figure 166 VLAN CPU Set Command Example

ras> switch vlan cpu set 2 

48.4.7 VLAN CPU Set Command

Syntax:

ras> switch vlan cpu set <vid> 

where

<vid> = The VLAN ID. Valid parameter range = [1 - 4094]. 

This command sets the management VLAN (CPU). You can only use ports that are members of this management VLAN in order to manage the IES-1248.

The following example sets VLAN ID 2 to be the CPU (management) VLAN.

Figure 167 VLAN CPU Set Command Example

ras> switch vlan cpu set 2 

48.4.8 Configuring Management VLAN Example

Note: After the following example configuration, you must connect to the first Ethernet port through a VLAN aware device that is using the proper VLAN ID in order to perform management.

By default, the IES-1248's ADSL ports are members of the management VLAN (VID 1). The following procedure shows you how to configure a tagged VLAN that limits management access to just one Ethernet port.

Note: Use the console port to configure the IES-1248 if you misconfigure the management VLAN and lock yourself out.

1 Use the switch vlan set command to configure a VLAN ID (VID 3 in this example) for managing the IES-1248 (the "management" or "CPU" VLAN).

Figure 168 CPU VLAN Configuration and Activation Example

ras> switch vlan set 3 enet1:FT 

2 Use the switch vlan1q vlan cpu command to set VID 3 as the management VLAN.

Figure 169 删除Default VLANExample

ras> switch vlan cpu set 3

Figure 177 MAC Filter Delete Command Example

ras> switch mac filter delete 5 00:a0:c5:12:34:56 

49.3 MAC Count Commands

Use MAC count commands to limit how many MAC addresses may be dynamically learned. MAC count commands are listed next. When the MAC filter accept mode is enabled (see Section 49.2 on page 321), the IES-1248 ignores the MAC count setting and accepts all of the MAC addresses listed for the port in the MAC filter settings.

49.3.1 MAC Count Show Command

Syntax:

ras> switch mac count show [portlist] 

where

[portlist] = You can specify a single ADSL port < 1> , all ADSL ports <^*> or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .

This command displays the MAC count settings on the specified ADSL port(s) or on all ADSL ports if no port is specified.

This command disables the MAC filtering feature on the specified ADSL port(s).

The following example turns off the MAC count filter on ADSL port 4.

Figure 180 MAC Count Disable Command Example

ras> switch mac count disable 4 

49.3.4 MAC Count Set Command

Syntax:

ras> switch mac count set <portlist> <count> 

where

= You can specify a single ADSL port <1> , all ADSL ports <^*> or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .

<count> = Set the limit for how many MAC addresses that a port may dynamically learn. For example, if you are configuring port 2 and you set this field to "5", then only five devices with dynamically learned MAC addresses may access port 2 at any one time. A sixth device would have to wait until one of the five learned MAC addresses ages out. 

The valid range is from "1" to "128".

This command sets the limit for how many MAC addresses may be dynamically learned on the specified ADSL port(s).

The following example sets the MAC count filter to allow up to 50 MAC addresses to be dynamically learned on ADSL port 7.

Figure 181 MAC Count Set Command Example

ras> switch mac count set 7 50 

CHAPTER 50 IGMP Commands

This chapter describes the IGMP snooping and filtering commands.

50.3 IGMP Filter Commands

Use the IGMP filter commands to define IGMP filter profiles and assign them to ADSL ports.

IGMP filter profiles allow you to control access to IGMP multicast groups. You can have a service available to a specific IGMP multicast group. You can configure an IGMP filter profile for an IGMP multicast group that has access to a service (like a SIP server for example). Then you can assign the IGMP filter profile to ADSL ports that are allowed to use the service.

50.3.1 IGMP Filter Show Command

ras> switch igmpsnoop bandwidth default <bandwidth> 

where

<bandwidth> = Allowed bandwidth between 1 and 1000 000 kbps (kilo bits per second). 

This command sets the default bandwidth for multicast channels for which you have not configured bandwidth requirements yet. Multicast bandwidth settings on channels (using the switch igmpsnoop bandwidth set command) have higher priority over this default setting.

50.4.2 IGMP Bandwidth Set Command

Syntax:

ras> switch igmpsnoop bandwidth set <index> <start-mcast-ip> <end-mcast-ip> <bandwidth> 

where

<index> = 1..96; a unique number for this setting. <start-mcast-ip> = 224.0.0.0..239.255.255.255; the beginning of the multicast range. 

<end-mcast-ip> = 224.0.0.0..239.255.255.255; the end of the multicast range. It must be greater than <start-mcast-ip>. 

<bandwidth> = 1..100000, in units of kbps 

This command configures bandwidth allocation for the multicast channel(s). For multicast channel(s) for which you have not configured bandwidth settings, the default multicast bandwidth setting applies (see the switch igmpsnoop bandwidth default command).

50.4.3 IGMP Bandwidth Delete Command

Syntax:

ras> switch igmpsnoop bandwidth delete <index> 

where

<index> = 1..96; a unique number for this setting.

This command activates multicast bandwidth setting on the specified port.

50.5.3 IGMP Bandwidth Port Set Command

Syntax:

ras> switch igmpsnoop bandwidth port set <portlist> <bandwidth> 

where

= You can specify a single ADSL port < 1> , all ADSL ports < *> or a list of ADSL ports < 1,3,5> . You can also include a range of ports < 1,5,6 10> .

<bandwidth> = 1..100000, in units of kbps 

This command sets the bandwidth allowed for multicast traffic on the specified port(s). It does not automatically enable it, however.

50.5.4 IGMP Bandwidth Port Show Command

Syntax:

ras> switch igmpsnoop bandwidth port show <portlist> 

where

50.6 IGMP Count Limit Commands

Use these commands to limit the number of IGMP groups a subscriber on a port can join. This allows you to control the distribution of multicast services (such as content information distribution) based on service plans and types of subscription.

IGMP count is useful for ensuring the service quality of high bandwidth services like video or Internet Protocol television (IPTV). IGMP count can limit how many channels (IGMP groups) the subscriber connected to a DSL port can use at a time. If each channel requires 4 5 Mbps of download bandwidth, and the subscriber's connection supports 11 Mbps, you can use IGMP count to limit the subscriber to using just 2 channels at a time. This also effectively limits the subscriber to using only two IPTVs with the DSL connection.

50.6.1 IGMP Count Disable Command

Syntax:

ras> switch igmpsnoop igmpcount disable <portlist> 

where

= You can specify a single ADSL port < 1> , all ADSL ports < *> or a list of ADSL ports < 1,3,5> . You can also include a range of ports < 1,5,6 10> .

CHAPTER 51

Packet Filter Commands

This chapter describes the packet filter commands.

51.1 Packet Filter Commands

Use the following packet filter commands to filter out specific types of packets on specific ports.

51.1.1 Packet Filter Show Command

Syntax:

ras> switch pktfilter show [portlist] 

where

[portlist] 

= You can specify a single ADSL port < 1> , all ADSL ports < *> or a list of ADSL ports < 1,3,5> . You can also include a range of ports < 1,5,6 10> .

This command displays the packet type filter settings on the specified ADSL port(s) or on all ADSL ports if no port is specified.

The following example displays the packet type filter settings for ADSL ports 1 and 2. "V" displays for the packet types that the IES-1248 is to accept on the port. "-" displays for packet types that the IES-1248 is to reject on the port (packet types that are not listed are accepted). When you use PPPoE only, "#" appears for all of the packet types. With PPPoE only, the IES-1248 rejects all packet types except for PPPoE (packet types that are not listed are also rejected).

Figure 202 Packet Filter Show Command Example

ras> switch pktfilter show 9  
V: pass through, -- filter out, #:Don't care  
E: Enable, D: Disable  
port pppoe ip arp netbios dhcp eapol igmp | PPPoE-Only  
1 # # # # # # # # | E  
2 - V V - V V V V | D 

51.1.2 Packet Filter Set Command

Syntax:

ras> switch pktfilter set [filter]

where

= You can specify a single ADSL port <1> , all ADSL ports <^*> or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .

[filter]

= [pppoe] Reject PPPoE packets. (Point-to-Point Protocol over Ethernet) relies on PPP and Ethernet. PPPoE is a specification for connecting the users on an Ethernet to the Internet through a common broadband medium, such as a single DSL line, wireless device or cable modem.

[ip] Reject IP packets. Internet Protocol. The underlying protocol for routing packets on the Internet and other TCP/IP-based networks.

[arp] Reject ARP packets. Address Resolution Protocol is a protocol for mapping an Internet Protocol address (IP address) to a physical computer address that is recognized in the local network.

[netbios] Reject NetBIOS packets. (Network Basic Input/Output System) are TCP or UDP packets that enable a computer to connect to and communicate with a LAN.

[ dhcp] Reject DHCP packets. Dynamic Host Configuration Protocol automatically assigns IP addresses to clients when they log on. DHCP centralizes IP address management on central computers that run the DHCP server program. DHCP leases addresses, for a period of time, which means that past addresses are "recycled" and made available for future reassignment to other systems.

[eapol] Reject EAPol packets. EAP (Extensible Authentication Protocol, RFC 2486) over LAN. EAP is used with IEEE 802.1x to allow additional authentication methods (besides RADIUS) to be deployed with no changes to the access point or the wireless clients.

[igmp] Reject IGMP packets. Internet Group Multicast Protocol is used when sending packets to a specific group of hosts.

[none] Accept all packets.

This command sets the packet type filter for the specified ADSL port(s).

The following example sets ADSL port 9 to reject ARP, PPPoE and IGMP packets.

Figure 203 Packet Filter Set Command Example

ras> switch pktfilter set 9 arp pppoe igmp 

51.1.3 Packet Filter PPPoE Only Command

Syntax:

ras> switch pktfilter pppoeonly<portlist> 

This command sets the IES-1248 to allow only PPPoE traffic on the specified ADSL port(s). The system will drop any non-PPPoE packets.

The following example sets ADSL port 1 to accept only PPPoE packets.

Figure 204 Packet Filter PPPoE Only Command Example

ras> switch pktfilter pppoeonly 1 

CHAPTER 52 IP Commands

This chapter shows you how to use the (standard shell) IP commands to configure the IP (Internet Protocol) parameters.

52.1 IP Commands Introduction

Use the IES-1248's management IP addresses to manage it through the network.

52.2 IP Settings and Default Gateway

Use the following command sequence to set the IES-1248's IP settings for the Ethernet 1 and 2, and DSL ports, VID and default gateway. With the Ethernet 1 and 2, and DSL ports, you must connect to the IES-1248 through a port that is a member of the management (CPU) VLAN in order to perform in-band management.

Figure 205 IP Settings and Default Gateway Address Commands

ras>ip set <new ip address> [/netmask>] ras>ip gateway <ip> ras> config save 

where

<new ip = The IP address you want to configure for the IES-1248.

address>

The bit number of the subnet mask of the IP address you want to configure for IES-1248's uplink, downlink and IES-1248 DSL ports. To find the bit number, convert the subnet mask to binary and add all of the 1's together. Take "255.255.255.0" for example. 255 converts to eight 1's in binary. There are three 255's, so add three eights together and you get the bit number (24).

= The default gateway IP address you want to configure for the IES-1248.

The first command changes the IP settings for the IES-1248's uplink, downlink and IES-1248 DSL ports. If you don't enter the subnet mask, the system automatically computes the subnet mask.

The second command changes the default gateway (next hop). This tells the IES-1248 where to send packets that have a destination IP address that is not on the same subnet as the IES-1248's IP address.

The third command saves the new configuration to the nonvolatile memory.

For example, use the following command sequence sets the IES-1248 to have 192.168.1.3 as the IP address, 255.255.255.0 for the subnet mask and 192.168.1.233 for the default gateway.

Figure 206 IP Settings and Default Gateway Address Command Example

ras>ip set 192.168.1.3/24 ras>ip gateway 192.168.1.233 ras>config save 

The IES-1248 leaves the factory with a default management IP address of 192.168.1.1 and a subnet mask of 255.255.255.0, (ff:ff:ff:00 in hexadecimal notation), and the default gateway set at 192.168.1.254. Make sure that you configure the IP parameters correctly before you connect a IES-1248 to the network, otherwise, you may interrupt services already running.

52.3 General IP Commands

The following is a list of general IP commands that help with the management of the IP parameters.

52.3.1 Show

Syntax:

ras>ip show 

Use the command to display the current management IP settings.

52.3.2 Ping Command

Syntax:

ras>ip ping <ip> [count] 

This is an IP facility to check for network functionality by sending an echo request to another IP host and waiting for the reply.

52.3.3 Route Set Command

Syntax:

ras>ip route set <dst ip>/[netmask]<gateway ip>[metric]<name> ras>ip route set default <gateway ip><metric> 

where

<dst ip> = The destination IP address of packets that this static route is to route.  
[/netmask] = The destination subnet mask of packets that this static route is to route.  
<gateway ip> = The IP address of the gateway that you want to send the packets through.  
[metric] = The metric (hop count) of this static route.  
<name> = A name to identify this static route. Up to 31 ASCII characters. Spaces and tabs are not allowed.  
default = Use this to configure the IES-1248's default route. 

This command defines a new, static IP forwarding route or edits an existing one.

52.3.4 Route Delete Command

Syntax:

ras>ip route delete <dstip>/netmask] 

where

<dst ip> = The destination IP address of packets to which this static route applies. 

[/netmask] = The destination subnet mask of packets to which this static route applies. 

This command removes a static, IP forwarding route.

52.3.5 Route Show Command

Syntax:

ras>iprouteshow 

This command displays the IES-1248's routing table.

An example is shown next.

Figure 207 Route Show Command Example

ras> ip route show
index	dest	gateway	metric name
1	192.168.1.0/24	192.168.1.1	1
2	default	192.168.1.254	1

52.3.6 ARP Show Command

Syntax:

ras>ip arp show 

This command displays the IES-1248's IP Address Resolution Protocol table. This is the list of IP addresses and matching MAC addresses that the IES-1248 has resolved.

An example is shown next.

CHAPTER 53 Firmware and Configuration File Maintenance

This chapter tells you how to upload a new firmware and/or configuration file for the IES-1248.

53.1 Firmware and Configuration File Maintenance Overview

The IES-1248's built-in FTP server allows you to use any FTP client (for example, ftp.exe in Windows) to upgrade IES-1248 firmware or configuration files. The firmware or configuration file upgrade is done during operation (run-time).

Note: Do not turn off the power to the IES-1248 during the file transfer process, as it may permanently damage your IES-1248.

Note: The IES-1248 automatically restarts when the upgrade process is complete.

53.2 Filename Conventions

The configuration file (called config-0) contains the factory default settings in the menus such as password, IP address, VLANs and so on. The configuration file arrives with a "rom" filename extension.

The OS (Operating System) firmware (sometimes referred to as the "ras" file) has a "bin" filename extension. With many FTP and clients, the filenames are similar to those shown next.

Figure 210 FTP Put Configuration File Example

ftp> put firmware.bin ras

This is a sample from a FTP session to transfer the computer file firmware.bin to the IES-1248.

Figure 211 FTP Get Configuration File Example

ftp> get config-0 config.txt

This is a sample from a FTP session to transfer the IES-1248's current configuration file (including the configuration files of all the IES-1248) to the computer file config.txt.

If your FTP client does not allow you to have a destination filename different than the source, you will need to rename them as the IES-1248 only recognizes "config-0" and "ras". Be sure you keep unaltered copies of the files for later use.

The following table is a summary. Please note that the internal filename refers to the filename on the IES-1248 and the external filename refers to the filename not on the IES-1248, that is, on your computer, local network or FTP site and so the name (but not the extension) may vary. After uploading new firmware, use the sys version command on the IES-1248 to confirm that you have uploaded the correct firmware version.

Table 97 Filename Conventions

FILE TYPE	INTERNAL NAME	EXTERNAL NAME	DESCRIPTION
Configuration File	config-0	*.dat	This is the configuration filename for the IES-1248.
Firmware	ras	*.bin	This is the Operating System firmware on the IES-1248.

CHAPTER 54 SNMP

This chapter covers Simple Network Management Protocol (SNMP) with the IES-1248.

54.1 SNMP Commands

Use these commands to configure SNMP settings. See Chapter 37 on page 237 for more information about SNMP.

54.1.1 Get Community Command

Syntax:

ras> sys snmp getcommunity

where

= The password for the incoming Get- and GetNext- requests from the management station.

Enter this command with the community to set the password.

54.1.2 Set Community Command

Syntax:

ras> sys snmp setcommunity

where

= The password for the incoming Set-requests from the management station.

Enter this command with the community to set the password.

54.1.3 Trusted Host Set Command

Syntax:

ras> sys snmp trusthost

where

<ip> = The IP address of a trusted host. 

Use this command to add the host IP address to the list of trusted hosts. If you enter a trusted host, your IES-1248 will only respond to SNMP messages from this address. If you leave the trusted host set to 0.0.0.0 (default), the IES-1248 will respond to all SNMP messages it receives, regardless of source.

54.1.4 Trap Community Command

Syntax:

ras> sys snmp trapcommunity <community> 

where

<community> = The password sent with each trap to the SNMP manager. 

Enter this command with the community to set the password.

54.1.5 Trap Destination Set Command

Syntax:

ras> sys snmp trapdst set <index> <ip> [<port>] 

where

= The number of the trap server (1 4)

<ip> = The IP address of the trap server. 

[<port>] = The port number upon which the trap server listens for SNMP traps. The IES-1248 uses the default of 162 if you do not specify a trap port. 

Use this command specify the IP address (and port number) of a trap server to which the IES-1248 sends SNMP traps. If you leave the trap destination set to 0.0.0.0 (default), the IES-1248 will not send any SNMP traps.

54.1.6 Show SNMP Settings Command

Syntax:

ras> sys snmp show 

This command displays the current SNMP get community, set community, trap community, trusted hosts and trap destination settings.

CHAPTER 55 ADSL Commands

This chapter describes some of the ADSL commands that allow you to configure and monitor the ADSL ports.

55.1 ADSL Commands

Use these commands to configure the ADSL ports. See Chapter 16 on page 119 for background information on ADSL.

55.1.1 ADSL Show Command

Syntax:

= You can specify a single ADSL port < 1> , all ADSL ports <^*> or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .

This command shows the activation status, ADSL mode, maximum upstream and downstream rate settings, profile and name of each ADSL port.

The following example displays information on ADSL port 5.

Figure 225 ADSL Show Command Example

ras> ADS1 show 5  
port enable mode up/downstream profile name  
--- -- auto 512/ 2048 DEFVAL 

55.1.2 ADSL Enable Command

Syntax:

ras> adssl enable <portlist> 

where

= You can specify a single ADSL port <1> , all ADSL ports <^*> or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .

This command forcibly enables the specified ADSL port(s).

55.1.3 ADSL Disable Command

Syntax:

ras> adsl disable <portlist> 

where

= You can specify a single ADSL port <1> , all ADSL ports <^*> or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .

This command forcibly disables the specified ADSL port(s).

Note: The factory default of all ports is enabled.

55.1.4 ADSL Profile Show Command

Syntax:

ras> adsl profile show [profile] 

where

<profile> = A profile name. 

This command displays the specified ADSL profile or all ADSL profiles if you do not specify one.

The following example displays the ADSL DEFVAL profile.

Figure 226 ADSL Profile Show Command Example

ras> ADS1 profile show DEFVAL  
01. DEFVAL latency mode: interleave up stream down stream max rate (kbps): 512 2048 min rate (kbps): 32 32 latency delay (ms): 4 4 max margin (db): 31 31 min margin (db): 0 0 target margin (db): 6 6 up shift margin(db): 9 9 down shift margin(db): 3 3 

55.1.5 ADSL Profile Set Command

Syntax:
where

ras> adsl profile set <profile> <fast|interleave[=<up delay>,<down delay>]>
<up max rate> <down max rate>
[<up target margin> <up min margin> <up max margin> <up min rate>
<down target margin> <down min margin> <down max margin> <down min rate>
<up down-shift margin> <up up-shift margin>
<down down-shift margin> <down up-shift margin>] 

<profile> = The descriptive name for the profile.  
<fast|interleav e [=<up delay>,<down delay>] = The latency mode. With interleave, you must also define the upstream and downstream delay (1-255 ms). It is recommended that you configure the same delay for both upstream and downstream.  
<up max rate> = The maximum ADSL upstream transmission rate (64-4096 Kbps).  
<down max rate> = The maximum ADSL downstream transmission rate (64-32000 Kbps).  
<up target margin> = The target ADSL upstream signal/noise margin (0-31db).  
<up min margin> = The minimum acceptable ADSL upstream signal/noise margin (0-31db).  
<up max margin> = The maximum acceptable ADSL upstream signal/noise margin (0-31db).  
<up min rate> = The minimum ADSL upstream transmission rate (32-4096 Kbps). 

<down target = The target ADSL downstream signal/noise margin (0-31db).  
margin>  
<down min = The minimum acceptable ADSL downstream signal/noise margin (0-31db).  
margin>  
<down max = The maximum acceptable ADSL downstream signal/noise margin (0-31db).  
margin>  
<down min rate = The minimum ADSL downstream transmission rate (32-32000 Kbps).  
margin>  
<up down shift = The upstream down shift noise margin (0~31 in dB).  
margin>  
<up up shift = The upstream up shift noise margin (0~31 in dB).  
margin>  
<down down = The downstream down shift noise margin (0~31 in dB).  
shift margin>  
<down up shift = The downstream up shift noise margin (0~31 in dB).  
margin>] 

The profile is a table that contains information on ADSL line configuration. Each entry in this table reflects a parameter defined by a manager, which can be used to configure the ADSL line.

Note that the default value will be used for any of the above fields that are omitted.

The upstream rate must be less than or equal to the downstream rate.

Even though you can specify arbitrary numbers in the profile set command, the actual rate is always a multiple of 32 Kbps. If you enter a rate that is not a multiple of 32 Kbps, the actual rate will be the next lower multiple of 32Kbps. For instance, if you specify 60 Kbps for a port, the actual rate for that port will not exceed 32 Kbps, and if you specify 66 Kbps, the actual rate will not be over 64Kbps.

The ADSL up/down shift noise margins define the threshold that triggers rate adaptation. For example:

The target SNR is 6, and the up/down shift noise margins are 9/3 .

If the signal becomes better and the SNR is higher than 9, rate adaptation is triggered and the line rate becomes higher

If the signal becomes bad and the SNR is lower than 3, rate adaptation is triggered and the line rate becomes lower.

The following example creates a premium profile (named gold) for providing subscribers with very high connection speeds and no interleave delay. It also sets the upstream target signal/ noise margin to 5 db, the upstream minimum acceptable signal/noise margin to 0 db, the upstream maximum acceptable signal/noise margin to 30 db, the upstream minimum ADSL

transmission rate to 128 Kbps, the downstream target signal/noise margin to 5 db, the downstream minimum acceptable signal/noise margin to 0 db, the downstream maximum acceptable signal/noise margin to 30 db and the downstream minimum ADSL transmission rate to 256Kbps.

The upstream down shift noise margin is 0 dB. The upstream up shift noise margin is 6 dB. The downstream down shift noise margin is 0 dB. The downstream up shift noise margin is 6 dB.

Figure 227 ADSL Profile Set Command Example 1

ras> ads1 profile set gold fast 1200 24000 5 0 30 128 5 0 30 256 0 6 0 6 

This next example creates a similar premium profile (named goldi), except it sets an interleave delay of 16 ms for both upstream and downstream traffic.

Figure 228 ADSL Profile Set Command Example 2

ras> adsl profile set goldi interleave=16,16 1200 24000 5 0 30 128 5 0 30 256 0 6 0 6 

After you create an ADSL profile, you can assign it to any of the ADSL ports on the IES-1248.

55.1.6 ADSL Profile Delete Command

Syntax:

ras> ads1 profile delete <profile> 

where

<profile> = A profile name. 

This command allows you to delete an individual ADSL profile by its name. You cannot delete a profile that is assigned to any of the DSL ports in the IES-1248. Assign a different profile to any DSL ports that are using the profile that you want to delete, and then you can delete the profile.

The following example deletes the gold ADSL profile.

Figure 229 ADSL Profile Delete Command Example

ras> ADS1 profile delete gold 

55.1.7 ADSL Profile Map Command

Syntax: (IES-1248-51/51A)

ras> adsl profile map <portlist> <profile>
-> <glite|gdmt|t1413|auto|ads12|ads12+> 

Syntax: (IES-1248-53)

ras> adsl profile map <portlist> <profile>
-> <gdmt|etsi|auto|ads12|ads12+> 

where

= You can specify a single ADSL port <1> , all ADSL ports <^*> or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .

<profile> = The profile that will define the settings of this port. 

<glite|gdmt|lets = The ADSL operational mode. The IES-1248-51/51A and the i|t1413|auto|ad IES-1248-53 have different choices. sl2|ads12+> 

This command assigns a specific profile to an individual port and sets the port's ADSL mode (or standard). The profile defines the maximum and minimum upstream/downstream rates, the target upstream/downstream signal noise margins, and the maximum and minimum upstream/ downstream acceptable noise margins of all the ADSL ports to which you assign the profile.

When set to auto, the port follows whatever mode is set on the other end of the line.

Note: When the mode is set to auto, the connection rates are governed by the negotiated ADSL mode regardless of the rates configured in the profile. For example, if the profile is set to use a rate of 18000 Kbps, that speed is only supported if the negotiated ADSL mode is ADSL 2+ . Any other ADSL mode will limit the rate to what is supported by the specific ADSL standard.

When the mode is set to auto in the IES-1248-51/51A, the t1413 mode has been removed from the auto mode selection list. When a profile is assigned to a line in auto mode, the line will not go to showtime if the modem is configured in t1413 mode only or if it is an old modem that only supports t1413. You have to explicitly configure the line in t1413 mode to make the modem initialize.

The following example sets ADSL port 1 to have the gold profile in G.dmt mode.

Figure 230 ADSL Profile Delete Command Example

ras> ADS1 profile map 1 gold gdmt

55.1.8 ADSL Name Command

Syntax:

ras> ads1 name <portlist> <name> 

where

= You can specify a single ADSL port < 1> , all ADSL ports < *> or a list of ADSL ports < 1,3,5> . You can also include a range of ports < 1,5,6 10> .

<name> = A descriptive name for the port. You can use up to 31 printable ASCII characters (including spaces and hyphens). 

This command sets the name of an ADSL port(s).

The following example sets ADSL port 5 to have the name super.

Figure 231 ADSL Name Command Example

= You can specify a single ADSL port < 1> , all ADSL ports < *> or a list of ADSL ports < 1,3,5> . You can also include a range of ports < 1,5,6 10> .

<tel> = An ADSL subscriber's telephone number. You can use up to 15 ASCII characters (including spaces and hyphens). 

This command records the telephone number of an ADSL subscriber telephone number.

The following example records the telephone number 12345678 for ADSL port 5.

Figure 232 ADSL Tel Command Example

= You can specify a single ADSL port < 1> , all ADSL ports < *> or a list of ADSL ports < 1,3,5> . You can also include a range of ports < 1,5,6 10> .
< f5> = Use f5 to perform an OAMF5 loopback test on the specified DSL port. An Operational, Administration and Maintenance Function 5 test is used to test the connection between two DSL devices. First, the DSL devices establish a virtual circuit. Then the local device sends an ATM F5 cell to be returned by the remote DSL device (both DSL devices must support ATM F5 in order to use this test).
= When you perform an OAMF5 loopback test, specify a VPI/ VCI.

This command has the IES-1248 perform an OAMF5 loopback test on the specified ADSL port(s).

The following example has the IES-1248 perform an OAMF5 loopback test on ADSL port 1's PVC at VPI 0 and VCI 33.

Figure 233 ADSL Loopback Command Example

ras> ads1 loopback 1 f5 0 33  
port[1] OAM F5 loopback test: failed 

55.1.11 ADSL Upstream PSD Command

Syntax:

ras> adsl usnompsd <portNo> [<max nominal psd>] 

where

<max nominal = -400 ~ 40 (unit of measure is 0.1dBm/Hz) psd> 

This command displays or sets the upstream maximum nominal transmit PSD (Power Spectral Density).

The following example sets the upstream maximum nominal transmit PSD for port 7 to -10 dBm/Hz.

Figure 234 ADSL Upstream PSD Command Example

ras> adsl usnompsd 7 -100 

55.1.12 ADSL Downstream PSD Command

Syntax:

ras> adsl dsnompsd <portNo> [<max nominal psd>] 

where

<max nominal = -400 ~ 40 (unit of measure is 0.1dBm/Hz) psd> 

This command displays or sets the downstream maximum nominal transmit PSD (Power Spectral Density).

The following example sets the downstream maximum nominal transmit PSD for port 7 to -10 dBm/Hz.

Figure 235 ADSL Downstream PSD Command Example

ras> ads1 dsnompsd 7 -100 

55.1.13 ADSL Upstream Carrier Command

Syntax:

ras> ads1 uscarrierportNo> [m0<m1>] 

where

<m0> , m1 = The upstream subcarriers to be masked (disabled). Each <mx> can use up to 8 hexadecimal digits (00000000~FFFFFF). Each <mx> represents 32 carrier tones (each hexadecimal digit represents 4 tones).

< m0> = tones 0~31

<m1> = tones 32~63

The hexadecimal digit is converted to binary and a '1' disables the corresponding tone. Disabling a carrier tone turns it off so the system does not send data on it.

The hexadecimal digit is converted to binary and a '1' masks (disables) the corresponding tone. Disabling a carrier tone turns it off so the system does not send data on it.

This command displays or sets masks for upstream carrier tones from 0 to 63. Masking a carrier tone disables the use of that tone on the specified ADSL port. Use this command to have the system not use an ADSL line's tones that are known to have a high noise level. The most significant bit defines the lowest tone number in a mask.

The most significant bit defines the first tone sequentially. For example, in m0 , 0x00000001 means tone 31. For example, you could use 0xFFFFFF0000 for m0 to disable upstream carrier tones 0~15 and leave tones 16~31 enabled.

The following example disables upstream carrier tones 0 15 for ADSL port 5.

Figure 236 ADSL Upstream Carrier Command Example

ras> adsl uscarrier 5 ffff0000 00000000 

The following example displays the results.

55.1.14 ADSL Downstream Carrier0 Command

Syntax:

ras> ads1 dscarrier0 <port number> [<ml> <m2> <m3> <m4> <m5> <m6> <m7>] 

where

<m1> - <m7> = The downstream carrier tones to be masked (disabled). Each <mx> can use up to 8 hexadecimal digits (0~FFFFFF). Each <mx> represents 32 carrier tones (each hexadecimal digit represents 4 tones).

< m1> = tones 32~63 < m2> = tones 64~95 < m3> = tones 96~127 < m4> = tones 128~159

< m5> = tones 160~191 < m6> = tones 192~223 < m7> = tones 224~255

The hexadecimal digit is converted to binary and a '1' masks (disables) the corresponding tone. Disabling a carrier tone turns it off so the system does not send data on it.

This command displays or sets masks for downstream carrier tones from 33 to 255. Masking a carrier tone disables the use of that tone on the specified ADSL port. The most significant bit defines the lowest tone number in a mask.

The following example disables downstream carrier tone 71 for ADSL port 5.

55.1.15 ADSL Downstream Carrier1 Command

Syntax:

ras> ads1 dscarrier1 <port number> [<m0> <m1> <m2> <m3> <m4> <m5> <m6> <m7>] 

where

<m0> - m7 = The downstream carrier tones to be masked (disabled). Each <mx can use up to 8 hexadecimal digits (0~FFFFFF). Each <mx represents 32 carrier tones (each hexadecimal digit represents 4 tones).

< m0> = tones 256~287 < m1> = tones 288~319 < m2> = tones 320~351 < m3> = tones 352~383 < m4> = tones 384~415 < m5> = tones 416~447 < m6> = tones 448~479 < m7> = tones 480~511

The hexadecimal digit is converted to binary and a '1' masks (disables) the corresponding tone. Disabling a carrier tone turns it off so the system does not send data on it.

This command displays or sets masks for downstream carrier tones from 256 to 511 on the specified ADSL2+ port(s). Use this command to have the system not use an ADSL line's tones that are known to have a high noise level.

The following example disables downstream carrier tone 307 for ADSL2+ port 5.

55.1.16 PMM Parameters Command

Syntax:

ras> ads1 pmm param <portlist> [<10time> <12time> <12atpr> <12atprt>]  
[<max_l2rate> <min_l2rate> <10tol2_rate>] 

where

= You can specify a single ADSL port <1> , all ADSL ports <^*> or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .

<10time> = Set the minimum time in seconds (10~65535) that the ADSL line must stay in L0 power mode before changing to the L2 power mode. 

<12time> = Set minimum time in seconds (10~65535) that the ADSL line must stay in the L2 power mode before reducing the power again in the L2 power mode. 

<12atpr> = Set the maximum Aggregate Transmit Power Reduction (ATPR) in decibels (dB) that is permitted in a L2 power reduction. The system can gradually decrease the ADSL line transmission power while it is in the L2 power mode. This is the largest individual power reduction allowed in the L2 power mode. The range is 0~15(dB). 

<12atprt> = Set the maximum Aggregate Transmit Power Reduction Total (ATPRT) in decibels (dB) that is permitted in the L2 power mode. This is the total transmit power decrease that is allowed to occur in the L2 power mode. The range is 0~15(dB). 

<max_l2rate> = Set the maximum transfer rate (in Kilobits per second) that is permitted while the port is in the L2 power mode. The supported range is 32~4096 Kbps in 4 Kbps increments. If you enter a number that is not a multiple of 4, the system uses the next lower multiple of 4. If you enter 39 for example, the system will use 36. 

<min_l2rate> = Set the minimum transfer rate (in Kilobits per second) that is permitted while the port is in the L2 power mode. The supported range is 32~4096 Kbps in 4 Kbps increments. If you enter a number that is not a multiple of 4, the system uses the next lower multiple of 4. If you enter 39 for example, the system will use 36. 

<10tol2_rate> = Set the down stream transfer rate (in Kilobits per second) that serves as the threshold for whether the port is to use the L0 or the L2 power mode. The system changes from L0 mode to L2 mode when the downstream transfer rate stays below this threshold for L0 Time. The system changes back from L2 mode to L0 mode when the downstream transfer rate goes above this threshold. This rate must be less than or equal to one half of the Min L2 Rate and at least 16 Kbps. 

Use this command to display or set Power ManageMent (PMM) parameters for the specified ADSL port(s).

The following example sets ADSL port 5 to use the following PMM settings.

• Stay in the L0 power mode for 180 seconds before a change to the L2 power mode is permitted.
• Once in L2 power mode, wait for 90 seconds before further reducing the transmission power.

55.1.17 Impulse Noise Protection Command

Syntax:

ras> adsl inp <portlist> [<usINP> [,<dsINP>] ] 

where

= Sets the minimum upstream (us) impulse noise protection setting. Use 0~3 to define a number of DMT symbols. 0 = 0 DMT symbols, 1 = 0.5 DMT symbols, 2 = 1 DMT symbols, 3 = 2 DMT symbols.

<dsINP> = Sets the minimum downstream (ds) impulse noise protection setting. Use 0~3 to define a number of DMT symbols. 0 = 0 DMT symbols, 1 = 0.5 DMT symbols, 2 = 1 DMT symbols, 3 = 2 DMT symbols. 

This command sets the upstream (us) and downstream (ds) impulse noise protection minimum setting on the specified ADSL port(s). Sudden spikes in the line's noise level (impulse noise) can cause errors and result in lost packets. Set the impulse noise protection minimum to have a buffer to protect the ADSL physical layer connection against impulse noise. This buffering causes a delay that reduces transfer speeds. It is recommended that you use a non-zero setting for real time traffic that has no error correction (like videoconferencing).

The following example sets the impulse noise protection minimum to 1 DMT symbols for upstream and 0.5 DMT symbols for downstream for ADSL port 5.

55.2.1 ADSL Show Command

Syntax:

ras> statistics ADS1 show [portlist] 

where

[portlist] = You can specify a single ADSL port < 1> , all ADSL ports < *> or a list of ADSL ports < 1,3,5> . You can also include a range of ports < 1,5,6 10> .

55.2.2 Linedata Command

Syntax:

ras> statistics adsl linedata <portlist> 

where

= You can specify a single ADSL port <1> , all ADSL ports <^*> or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .

This command shows the line bit allocation of an ADSL port.

Discrete Multi-Tone (DMT) modulation divides up a line's bandwidth into tones. This command displays the number of bits transmitted for each tone. This can be used to determine the quality of the connection, whether a given sub-carrier loop has sufficient margins to support ADSL transmission rates, and possibly to determine whether certain specific types of interference or line attenuation exist. See the ITU-T G.992.1 recommendation for more information on DMT.

The better (or shorter) the line, the higher the number of bits transmitted for a DMT tone. The maximum number of bits that can be transmitted per DMT tone is 15.

"upstream carrier load" displays the number of bits transmitted per DMT tone for the upstream channel (from the subscriber's DSL modem or router to the IES-1248).

"downstream carrier load" displays the number of bits received per DMT tone for the downstream channel (from the IES-1248 to the subscriber's DSL modem or router).

The bit allocation contents are only valid when the link is up.

In the following example, the upstream channel is carried on tones 7 to 39 and the downstream channel is carried on tones 53 to 259 (space is left between the channels to avoid interference).

where

<portlist> 

= You can specify a single ADSL port <1> , all ADSL ports <^*> or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .

This command shows the line operating values of an ADSL port.

An example is shown next.

The service type in operation is the ADSL standard that the port is using: G.dmt (IES-1248-51/51A), G.dmt Annex B (IES-1248-53), ETSI (IES-1248-53), Glite (IES-1248-51/51A), ANSI T1.413 issue 2 (IES-1248-51/51A), ADSL2, or ADSL2+.

Trellis coding helps to reduce the noise in ADSL transmissions. Trellis may reduce throughput but it makes the connection more stable.⁴

The numbers of milliseconds of interleave delay for downstream and upstream transmissions are listed. The total output power of the transceiver varies with the length and line quality. The farther away the subscriber's ADSL modem or router is or the more interference there is on the line, the higher the power will be. "DS" refers to the power output of the IES-1248 "US" refers to the power output of the subscriber's ADSL modem or router.

Information obtained prior to training to steady state transition will not be valid or will be old information.

The atuc information fields show data acquired from the ATUC (ADSL Termination Unit – Central), in this case IES-1248, during negotiation/provisioning message interchanges.

The atrur information fields show data acquired from the ATUR (ADSL Termination Unit - Remote), in this case the subscriber's ADSL modem or router, during negotiation/provisioning message interchanges. This information can help in identifying the subscriber's ADSL modem or router.

The vendor ID, vendor version number and product serial number are obtained from vendor ID fields (see ITU-T G.994.1) or R-MSGS1 (see T1.413).

55.2.12 Tone Diagnostics 992.3 Command

Syntax:

ras> adsl linediag toneDiag <port number> 

Use this command to display the tone diagnostics for a port in the format defined in the ITU-T G.992.3 standard. You do not need to use the line diagnostics set command first. Use the tone diagnostics to analyze problems with the physical ADSL line.

The following example displays the tone diagnostics results for ADSL port 8.

Figure 263 Tone Diagnostics Command Example

The following table lists the tone diagnostic parameters. See the ITU-T's G.992.3 for more information.

Table 102 ToneDiag Command

LABEL	DESCRIPTION
number_of_subcarries	Discrete Multi-Tone (DMT) modulation divides up a line's bandwidth into sub-carriers (sub-channels) of 4.3125 KHz each.This number indicates how many upstream and downstream DMT sub-carriers the ADSL connection is using.
hlinScale:	The channel characteristics function is represented in linear format by a scale factor and a complex number. This is the maximum upstream and downstream scale factor used in producing the channel characteristics function.
latn:	This is the upstream and downstream Line Attenuation (in dB).
satn:	This is the upstream and downstream Signal Attenuation (in dB).
snrm:	This is the upstream and downstream Signal-to-Noise Ratio Margin (in dB). A DMT sub-carrier's SNR is the ratio between the received signal power and the received noise power. The signal-to-noise ratio margin is the maximum that the received noise power could increase with the IES-1248 still being able to meet its transmission targets.
attndr:	This is the upstream and downstream Attainable Net Data Rate (in bit/s).
farEndActatp:	This is the upstream and downstream Far End Actual Aggregate Transmit Power (in dBm)
i	This is the index number of the DMT sub-carrier.
log (dB)	This is a format for providing channel characteristics. It provides magnitude values in a logarithmic scale. This can be used in analyzing the physical condition of the ADSL line.
QLN (dBm)	The Quiet Line Noise for a DMT sub-carrier is the rms (root mean square) level of the noise present on the line, when no ADSL signals are present. It is measured in dBm/Hz. The QLN can be used in analyzing crosstalk.
SNR (dB)	This is the upstream and downstream Signal-to-Noise Ratio (in dB). A DMT sub-carrier's SNR is the ratio between the received signal power and the received noise power. The SNR can be used in analyzing time dependent changes in crosstalk levels and line attenuation (such as those caused by temperature variations and moisture).

55.3 Alarm Profile Commands

Configure alarm profiles to set alarm settings and thresholds for the ADSL ports.

55.3.1 Alarm Profile Show Command

Syntax:

ras> adssl alarmprofile show [profile]

where

[profile] = The name of an alarm profile.

Displays the settings of the specified alarm profile (or all of them if you do not specify one).

55.3.2 Alarm Profile Set Command

Syntax:

ras> adsl alarmprofile set [ ]

where

= A name for the alarm profile (up to 31 ASCII characters).
atuc = Upstream. These parameters are for the connection (or traffic) coming from the subscriber's device to the IES-1248.
atur = Downstream. These parameters are for the connection (or traffic) going from the IES-1248 to the subscriber's device.

<atuc ess> = The number of Errored Seconds that are permitted to occur within 15 minutes.  
<atur ess> = A rate in kilobits per second (kbps). If a fast mode connection's upstream transmission rate increases by more than this number, then a trap is sent.  
<atuc fast rateup> <atur fast rateup> = A rate in kilobits per second (kbps). If an interleave mode connection's upstream transmission rate increases by more than this number, then a trap is sent.  
<atuc interleave rateup> <atur interleave rateup> = A rate in kilobits per second (kbps). If a fast mode connection's downstream transmission rate decreases by more than this number, then a trap is sent.  
<atuc fast ratedown> <atur fast ratedown> = A rate in kilobits per second (kbps). If an interleave mode connection's upstream transmission rate decreases by more than this number, then a trap is sent.  
<atuc interleave ratedown> <atur interleave ratedown> = A rate in kilobits per second (kbps). If an interleave mode connection's upstream transmission rate decreases by more than this number, then a trap is sent.  
<init fail enable> = "1" sets the profile to trigger an alarm for an initialization failures trap. "2" sets the profile to not trigger an alarm for an initialization failures trap.  
<atuc fail fast> = The number of failed fast retrans that are permitted to occur within 15 minutes.  
<atuc ses> = The number of Severely Errored Seconds that are permitted to occur within 15 minutes.  
<atur ses> = The number of UnAvailable Seconds that are permitted to occur within 15 minutes. 

This command configures settings and thresholds that define when the IES-1248 is to send an alarm trap and generate a syslog entry.

Configure alarm profiles first and then use the alarmprofile map command to set the IES-1248 to use them with specific ADSL ports.

The following example sets an alarm profile named SESalarm that has the IES-1248 send an alarm trap and generate a syslog whenever the upstream connection's number of severely errored seconds exceeds three within a 15 minute period.

CHAPTER 56

Virtual Channel Management

This chapter shows you how to use commands to configure virtual channels.

56.1 Virtual Channel Management Overview

See Chapter 16 on page 119 for background information on virtual channels and ATM QoS.

56.2 Virtual Channel Profile Commands

Use the following commands to configure virtual channel profiles.

56.2.1 Show Virtual Channel Profile Command

Syntax:

ras> ads1 vcprofile show [vcprofile]

where

[vcprofile] = The name of the virtual channel profile (up to 31 ASCII characters).

Displays the settings of the specified virtual channel profile (or all of them if you do not specify one).

56.2.2 Set Virtual Channel Profile Command

Syntax:

ras> adsl vcprofile set <vcprofile> <vc|llc> <ubr|cbr> <pcr> <cdvt> ras> adsl vcprofile set <vcprofile> <vc|llc> <vbr(rt-vbr)|nrt-vbr> <pcr> <cdvt> <scr> <bt> 

where

<vcprofile> = The name of the virtual channel profile (up to 31 ASCII characters). You cannot change the DEFVAL or DEFVAL_VC profiles. 

<vc|11c> = The type of encapsulation (vc or llc). 

<ubr|cbr> = The ubr (unspecified bit rate) or cbr (constant bit rate) or ATM traffic class.  
<pcr> = Peak Cell Rate (150 to 300000), the maximum rate (cells per second) at which the sender can send cells.  
[cdvt] = Cell Delay Variation Tolerance is the accepted tolerance of the difference between a cell's transfer delay and the expected transfer delay (number of cells). 0 to 255 cells or * (means 0).  
<vbr(rt-vbr)|nrt-vbr> = The real-time (vbr) or non real-time (nrt-vbr) Variable Bit Rate ATM traffic class.  
<scr> = The Sustained Cell Rate sets the average cell rate (long-term) that can be transmitted (cells per second). SCR applies with the vbr traffic class.  
<bt> = Burst Tolerance this is the maximum number of cells that the port is guaranteed to handle without any discards (number of cells). BT applies with the vbr traffic class. 

This command creates a virtual channel profile. After you create a virtual channel profile, you can assign it to any of the ADSL ports on any of the ADSL IES-1248 in the IES-1248.

The following example creates a virtual channel profile named gold that uses LLC encapsulation. It uses constant bit rate and has the maximum rate (peak cell rate) set to 300,000 cells per second. The acceptable tolerance of the difference between a cell's transfer delay and the expected transfer delay (CDVT) is set to 5 cells.

Figure 269 Set Virtual Channel Profile Command Example 1

ras> adsl vcprofile set gold llc cbr 300000 5 

The following example creates a virtual channel profile named silver that uses VC encapsulation. It uses real-time variable bit rate and has the maximum rate (peak cell rate) set to 250,000 cells per second. The acceptable tolerance of the difference between a cell's transfer delay and the expected transfer delay (CDVT) is set to 5 cells. The average cell rate that can be transmitted (SCR) is set to 100,000 cells per second. The maximum number of cells that the port is guaranteed to handle without any discards (BT) is set to 200.

Figure 270 Set Virtual Channel Profile Command Example 2

ras> adsl vprofile set silver vc vbr 250000 5 100000 200 

The following example creates a virtual channel profile named economy that uses LLC encapsulation. It uses unspecified bit rate and has the maximum rate (peak cell rate) set to 50,000 cells per second. The acceptable tolerance of the difference between a cell's transfer delay and the expected transfer delay (CDVT) is set to 100 cells.

Figure 271 Set Virtual Channel Profile Command Example 3

ras> adsl vprofile set gold l1c cbr 50000 100 

56.2.3 Delete Virtual Channel Profile Command

Syntax:

ras> adsl vprofile delete <vcprofile> 

where

<vcprofile> = The name of the virtual channel profile (up to 31 ASCII characters). You cannot delete the DEFVAL or DEFVAL_VC profiles. 

You cannot delete a virtual channel profile that is assigned to any of the ADSL ports. Assign a different profile to any ADSL ports that are using the profile that you want to delete, and then you can delete the profile.

The following example deletes the silver virtual channel profile.

Figure 272 Delete Virtual Channel Profile Command Example

ras> adsl vprofile delete silver 

56.3 PVC Channels

Channels (also called Permanent Virtual Circuits or PVCs) let you set priorities for different services or subscribers. You can define up to eight channels on each DSL port and use them for different services or levels of service. You set the PVID that is assigned to untagged frames received on each channel. You also set an IEEE 802.1p priority for each of the PVIDs. In this way you can assign different priorities to different channels (and consequently the services that get carried on them or the subscribers that use them). Use the following commands to define channels.

56.3.1 PVC Show Command

Syntax:

ras> adsl pvc show [portlist] [<vpi><vci>] 

where

= You can specify a single ADSL port <1> , all ADSL ports <^* or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .

<vpi> < vci> = The VPI and VCI of an individual PVC.

This command allows you to display the PVC parameters of the specified ADSL port(s) or all of the ADSL ports if you do not specify any.

56.3.2 PVC Set Command

Syntax:

ras> adsl pvc set > ]

where

= You can specify a single ADSL port < 1> , all ADSL ports < *> or a list of ADSL ports < 1,3,5> . You can also include a range of ports < 1,5,6 10> .

= The VPI setting can be 0 to 255.

= The VCI setting can be 32 to 65535 if the vpi is 0 or 1 to 65535 if the vpi is not 0.
<super | vid = Enable the super channel option to allow a channel forward frames belonging to multiple VLAN groups (that are not assigned to other channels). The IES-1248 forwards frames belonging to VLAN groups that are not assigned to specific channels to the super channel. The super channel functions in the same way as the channel in a single channel environment. One port can have only one super channel.
The default VID (1 to 4094). Each PVC must have a unique VID since the IES-1248 forwards traffic back to the subscribers based on the VLAN ID.
= This is the priority value (0 to 7) to add to incoming frames without a (IEEE 802.1p) priority tag.
DS vcprofile = Assign a VC profile to use for this channel's downstream traffic shaping.

[,US = Assign a VC profile to use for policing this channel's upstream traffic. The IES-1248 does not perform upstream traffic policing if you do not specify an upstream VC profile. 

This command allows the configuration of a PVC (permanent virtual circuit) for one or a range of ADSL ports.

The following example sets a PVC on ADSL port 1 with VPI 1, VCI 34, default VID 100 priority 3. It sets the "platinum" profile for downstream traffic shaping and a VC profile named "plus" for upstream traffic policing.

Figure 273 PVC Set Command Example

ras> ads1 pvc set 1 1 34 100 3 platinum,plus 

56.3.3 PVC Delete Command

Syntax:

ras> adsl pvc delete <portlist> <vpi> <vci> 

where

= You can specify a single ADSL port <1> , all ADSL ports <^*> or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .

[ \left[ <\mathrm{vpi}> <\mathrm{vci}> \right] = \text{The VPI and VCI of an individual PVC.} ] 

This command deletes the specified PVC channel.

56.4 Priority-based PVCs

A PPVC (Priority-based PVC) allows you to give different priorities to PVCs that are members of the same VLAN.

The IES-1248 uses eight priority queues (also called levels) for the member PVCs. The system maps frames with certain IEEE 802.1p priorities to a PVC with a particular priority queue. See Chapter 16 on page 119 for the factory default mapping.

Use these commands to configure PPVCs and add and remove member PVCs.

56.4.1 PPVC Set Command

Syntax:

ras> adsl ppvc set

where

= You can specify a single ADSL port <1> , all ADSL ports <* or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .
= The VPI setting can be 0 to 255.
= The VCI setting can be 32 to 65535 if the vpi is 0 or 1 to 65535 if the vpi is not 0. This PVC channel is for internal use. The operator does not need to create this PVC on the subscriber's device (the CPE).
= The type of encapsulation: llc, vcmux
= Type a PVID (Port VLAN ID) to assign to untagged frames received on this PPVC.
= This is the priority value (0 to 7) to add to incoming frames without a (IEEE 802.1p) priority tag.

This command creates a PPVC.

The following example creates a PPVC with VPI 8 and VCI 35 for port 5. The PPVC uses llc encapsulation and default VID 25. Any frames received without an IEEE 802.1p priority tag will be assigned a priority of 3. The IES-1248 uses this PVC channel internally. This PVC is not needed on the subscriber's device.

Figure 274 PPVC Set Command Example

ras> ads1 ppvc set 5 8 35 11c 25 3 

56.4.2 PPVC Member Set Command

Syntax:

ras> adsl ppvc member set

where
= The port(s) of the PPVC.
You can specify a single ADSL port <1> , all ADSL ports <* or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .
= The VPI of the PPVC.
= The VCI of the PPVC. This PVC channel is for internal use. The subscriber does not need to create this PVC.
= The VPI of the individual PVC that you are adding to the PPVC. The VPI setting can be 0 to 255.
= The VCI of the individual PVC that you are adding to the PPVC. The VCI setting can be 32 to 65535 with a VPI of 0 or 1 to 65535 if the VPI is not 0. The subscriber's device must create this PVC.
DS vcprofile = Assign a VC profile to use for this channel's downstream traffic shaping.
[,US vcprofile>] = Assign a VC profile to use for policing this channel's upstream traffic. The IES-1248 does not perform upstream traffic policing if you do not specify an upstream VC profile.
= The priority queue (0 7) to use for this PVCs traffic. 7 is the highest priority.

This command adds a member PVC to a PPVC. You must create the PPVC before you use this command to add a member.

Note: Only the member PVCs need to be created on the subscriber's device.

The following example adds a PVC to a PPVC with VPI 8 and VCI 35 for port 5. The PVC uses VPI 8 and VCI 36. It sets the DEFVAL profile for downstream traffic shaping and for upstream traffic policing. It uses priority queue 2.

Figure 275 PPVC Member Set Command Example

ras> ads1 ppvc member set 5 8 35 8 36 DEFVAL,DEFVAL 2 

56.5 PPVC Member Delete Command

Syntax:

ras> adsl ppvc member delete <portlist> <vpi> <vci> <member vpi> <member vci> 

where

= The port(s) of the PPVC.
You can specify a single ADSL port <1> , all ADSL ports <* > or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .
= The VPI of the PPVC.
= The VCI of the PPVC.
= The VPI of the individual PVC that you are removing from the PPVC.
= The VCI of the individual PVC that you are removing from the PPVC.

This command removes a PVC from a PPVC.

The following example removes a PVC that uses VPI 8 and VCI 36 from a PPVC with VPI 8 and VCI 35 for port 5.

You can specify a single ADSL port <1> , all ADSL ports <串> or a list of ADSL ports <1,3,5> . You can also include a range of ports <1,5,6 10> .
= The VPI of the PPVC.
= The VCI of the PPVC.
= The VPI of the individual PVC that you are displaying.
= The VCI of the individual PVC that you are displaying.

This command displays the PVCs that are members of a PPVC.

The following example displays the PVCs that are members of a PPVC for port 5.

ras> ads1 ppvc delete 5 8 35 

56.7 2684 Routed Mode Commands

Use the 2684 routed mode to have the IES-1248 add MAC address headers to 2684 routed mode traffic from a PVC that connects to a subscriber device that uses 2684 routed mode. You can also specify the gateway to which the IES-1248 sends the traffic and the VLAN ID tag to add. See RFC-2684 for details on routed mode traffic carried over AAL type 5 over ATM.

Use the commands in the following order to set up a 2684 routed mode PVC.

1 Use the ads1 rpvc gateway commands to configure gateway settings.
2 Use the ads1 rpvc set command to configure RPVCs (2684 routed mode PVCs) for 2684 routed mode traffic.
3 Use the adsl rpvc route set command to configure domains for 2684 routed mode traffic. The domain is the range of IP addresses behind the subscriber's device (the CPE or Customer Premises Equipment). This includes the CPE device's LAN IP addresses and the IP addresses of the LAN computers.
4 Use the ads1 rpvc arp commands to view the Address Resolution Protocol table of IP addresses of CPE devices using 2684 routed mode and configure how long the device is to store them.
5 For upstream traffic: Since the subscriber's device will not send out a MAC address, after the IES-1248 reassembles the Ethernet packets from the AAL5 ATM cells, the IES-1248 will append the routed mode gateway's MAC address and the IES-1248's MAC address as the destination/source MAC address.
6 For downstream traffic: When the IES-1248 sees the destination IP address is specified in the RPVC (or RPVC domain), the IES-1248 will strip out the MAC header and send them to the corresponding RPVC.

56.7.1 2684 Routed Mode Example

The following figure shows an example RFC 2684 (formerly RFC 1483) routed mode set up. The gateway server uses IP address 192.168.10.102 and is in VLAN 1. The IES-1248 uses IP address 192.168.20.101. The subscriber's device (the CPE) is connected to DSL port 1 on the IES-1248 and the 2684 routed mode traffic is to use the PVC identified by VPI 8 and VCI 35. The CPE device's WAN IP address is 192.168.10.200. The routed domain is the LAN IP addresses behind the CPE device. The CPE device's LAN IP address is 10.10.10.10 and the LAN computer's IP address is 10.10.10.1. This includes the CPE device's LAN IP addresses and the IP addresses of the LAN computers.

Figure 280 2684 Routed Mode Example

Note the following.

• The CPE device's WAN IP (192.168.10.200 in this example) must be in the same subnet as the gateway's IP address (192.168.10.102 in this example).
• The IES-1248's management IP address can be any IP address, it doesn't have any relationship to the WAN IP address or routed gateway IP address.
• The IES-1248's management IP address should not be in the same subnet as the one defined by the WAN IP address and netmask of the subscriber's device. It is suggested that you set the netmask of the subscriber's WAN IP address to 32 to avoid this problem
• The IES-1248's management IP address should not be in the same subnet range of any RPVC and RPVC domain. It will make the IES-1248 confused if the IES-1248 receives a packet with this IP as destination IP.

• The IES-1248's management IP address also should not be in the same subnet as the one defined by the LAN IP address and netmask of the subscriber's device. Make sure you assign the IP addresses properly.

• In general deployment, the computer must set the CPE device's LAN IP address (10.10.10.10 in this example) as its default gateway.

• The subnet range of any RPVC and RPVC domain must be unique.

Use the following command sequence to configure the IES-1248 for this example set up.

56.7.2 RPVC Gateway Set Command

Syntax:

ras> adsl rpvc gateway set <gateway ip> <vlan id> [<priority>] 

where

<gateway ip> = The IP address of the gateway to which you want to send the traffic that the system receives from this PVC. Enter the IP address in dotted decimal notation. 

<vlan id> = The VLAN Identifier to add to Ethernet frames that the system routes to this gateway. 

[<priority>] = Set the IEEE 802.1p priority (0~7) to add to the traffic that you send to this gateway. 

This command adds a gateway IP address to use for 2684 routed mode traffic.

<ip> = The subscriber's CPE WAN IP address in dotted decimal notation.  
</netmask> = The bit number of the subnet mask of the subscriber's IP address. To find the bit number, convert the subnet mask to binary and add all of the 1's together. Take “255.255.255.0” for example. 255 converts to eight 1's in binary. There are three 255's, so add three eights together and you get the bit number (24).  
Make sure that the routed PVC's subnet does not include the IES-1248's IP address.  
<gateway ip> = The IP address of the gateway to which you want to send the traffic that the system receives from this PVC. Enter the IP address in dotted decimal notation. 

This command adds a PVC to handle 2684 routed mode traffic.

Note: You must use the rpvc gateway set command to configure the gateway's settings before you use the rpvc set command.

The following example adds a PVC for 2684 routed mode traffic. It is for DSL port 1, VPI 8, VCI 35. It sets the DEFVAL profile for downstream traffic shaping and for upstream traffic policing.

CHAPTER 57 ACL Commands

An ACL (Access Control Logic) profile allows the system to classify and perform actions on the upstream traffic. Use the ACL Profile commands to set up ACL profiles and the ACL Assignment commands to apply them to PVCs.

57.1 ACL Profile Commands

Use these commands to set up ACL profiles.

57.1.1 ACL Profile Set Command

Syntax:

ras> switch acl profile set <name> <rule> <action> 

where

<name> = The name of the ACL profile. 

<rule> = The rule that classifies traffic flows. See below. 

<action> = One or more actions to perform on the classified packets. You can select one or more of the following actions. 

• rate = Sets the transmission rate (1~65535 in kbps) for the matched traffic.
• rvlan = Replaces the VLAN ID with this VLAN ID (1~4094).
• rpri = Replaces the priority with this priority (0 ~7) of the matched packets.
• deny = Drops the packets.

This command configures an ACL rule to classify the upstream traffic and perform action(s) on the classified traffic.

The following lists the set of criteria you can configure for rules in ACL profiles. The rules are listed in sequence from highest priority to lowest priority. The criteria within a rule are position-independent.

• etype vlan
• etype smac
• etype dmac

- vlan < vid > smac <mac>
- vlan < vid > dmac <mac>
- smac < mac > dmac <mac>
- vlan < vid > priority <priority>
- etype <etype>
- vlan <vid>
- smac <mac>
- dmac <mac>
- priority <priority>
- protocol <protocol>
- srcip <ip>/<mask> [dstip <ip>/<mask> [tos <tos> [srcport <sport> [dstport <sport> <eport>] ]] 

where

• etype = Ethernet type (0~65535).
• vlan = VLAN ID (1~4094).
• smac = Source MAC address.
• dmac = Destination MAC address.
• priority = Priority (0 ~ 7)
• protocol = Protocol type: tcp, udp, ospf, igmp, ip, gre, icmp or user specified IP protocol number < 0 255> .
• srcip / = Source IP address and subnet mask (0~32).
• dstip / = Destination IP address and subnet mask (0~32).
• tos = Sets the ToS (Type of Service) range between 0 and 255.
• srcport = Source port range (0~65535).
• dstport = Destination port range (0~65535).

The following guidelines apply to classifiers.

• You can apply one classifier for a protocol on a port's PVC.
• You cannot create a classifier that contains matching criteria for layer 2 and layer 3 fields. For example switch acl profile set test protocol tcp vlan 15 deny is not allowed as protocol type and VLAN do not belong to the same network layer.
• Each type of criteria can only be used once in a classifier. For example, profile acl set test protocol tcp protocol udp deny is not allowed. For this example, you need to create a separate classifier for each protocol and apply them to the same PVC(s).

The following example creates an ACL rule example named test for traffic from VLAN 10 with a priority level of 2. This rule limits the rate on the classified traffic to 1000 kbps and changes the priority level to 7.

Figure 300 ACL Profile Set Command Example

ras> switch acl profile set test vlan 10 priority 2 rate 1000 rpri 7

3	The LED itself or the unit may be faulty; contact your vendor.

58.2 The ALM LED Is On

The ALM (alarm) LED lights when the IES-1248 is overheated, the fans are not working properly, the voltage readings are outside the tolerance levels or an alarm has been detected on the ALARM input pins.

Table 104 ALM LED Troubleshooting

STEP	CORRECTIVE ACTION
1	Use the statistics monitor command to verify the cause of the alarm. See step 2 if the unit is overheated, step 3 if the problem is with the fans and step 4 if the voltages are out of the allowed ranges.
2	Ensure that the IES-1248 is installed in a well-ventilated area and that normal operation of the fans is not inhibited. Keep the bottom, top and all sides clear of obstructions and away from the exhaust of other equipment.
3	Make sure you can feel and/or hear the fans working - working fans emit a low buzz and blow air.
4	If the voltage levels are outside the allowed range, take a screen shot of the statistics monitor command display and contact your vendor.

58.3 SFP LNK LEDs Do Not Turn On

The LEDs for one of the SFP slots do not turn on.

Table 105 SFP LNK LED Troubleshooting

STEPS	CORRECTIVE ACTION
1	Make sure that the Ethernet port's mode is set to match that of the peer Ethernet device.
2	Check the cable and connections between the SFP slot and the peer Ethernet device.
3	Check the mini GBIC transceiver.
4	Make sure that the peer Ethernet device is functioning properly. If the cable, transceiver and peer Ethernet device are all OK and the LEDs stay off, there may be a problem with the SFP slot. Contact the distributor.

58.4 100/1000 LEDs Do Not Turn On

A 100/1000 Ethernet port's LEDs do not turn on.

Table 106 100/1000 LED Troubleshooting

STEPS	CORRECTIVE ACTION
1	Each 100/1000M RJ-45 Ethernet port is paired with a mini GBIC slot. The IES-1248 uses one connection per pair.
2	Check the Speed Mode settings in the ENET Port Setup screen. Make sure that the 100/1000 Ethernet port's connection speed is set to match that of the port on the peer Ethernet device. When an Ethernet port is set to Auto, the IES-1248 tries to make a fiber connection first and does not attempt to use the RJ-45 port if the fiber connection is successful.
3	Check the Ethernet cable and connections between the 100/1000 Ethernet port and the peer Ethernet device. Use 1000Base-T 4-pair (8 wire) UTP Cat. 5 Ethernet cables with the RJ-45 interface.
4	Make sure that the peer Ethernet device is functioning properly. If the Ethernet cable and peer Ethernet device are both OK and the LEDs still stay off, there may be a problem with the port. Contact the distributor.

58.5 100/1000 Ethernet Port Data Transmission

The Ethernet port's LED is on, but data cannot be transmitted.

Table 107 Troubleshooting Data Transmission

STEPS	CORRECTIVE ACTION
1	Make sure that the Ethernet port has the appropriate mode setting.
2	Make sure that the IES-1248's IP settings are properly configured.
3	Check the VLAN configuration.
4	Ping the IES-1248 from a computer behind the peer Ethernet device.
5	If you cannot ping, check the Ethernet cable and connections between the Ethernet port and the Ethernet switch or router.
6	Check the switch mode. In daisychain mode, if you have a loop topology and enable RSTP, it is possible for RSTP to disable Ethernet port 1 (the uplink port).Note: It is not recommended to use daisychain mode in a loop topology.

58.6 DSL Data Transmission

The DSL link is up, but data cannot be transmitted.

Table 108 DSL Data Transmission Troubleshooting

STEPS	CORRECTIVE ACTION
1	Check the switch mode and port isolation settings. Check to see that the VPI/VCI and multiplexing mode (LLC/VC) settings in the subscriber's ADSL modem or router match those of the ADSL port. If the subscriber is having problems with a video or other high-bandwidth services, make sure the IES-1248's ADSL port's data rates are set high enough.
2	Check the VLAN configuration.
3	Ping the IES-1248 from the computer behind the ADSL modem or router.
4	If you cannot ping, connect a DSL modem to an ADSL port (that is known to work). If the ADSL modem or router works with a different ADSL port, there may be a problem with the original port. Contact the distributor.
5	If using a different port does not work, try a different ADSL modem or router with the original port.

58.7 There Is No Voice on an ADSL Connection

The IES-1248 has internal POTS (Plain Old Telephone Service) splitters and CO side Telco-50 connectors that allow the telephone wiring used for ADSL connections to also simultaneously carry normal voice conversations.

Table 109 ADSL Voice Troubleshooting

STEP	CORRECTIVE ACTION
1	Make sure the subscriber has a POTS splitter properly installed.
2	Check the ADSL line pin assignments shown in Appendix C on page 449.
3	Check the telephone wire connections between the subscriber and the MDF(s).
4	Check the telephone wire and connections between the MDF(s) and USER port(s).
5	Check the telephone wire and connections between the MDF(s) and the CO connector(s). Check the connection from the MDF(s) to the telephone company or the PBX.
6	Check the telephone wire mapping on the MDF(s).
7	Make sure the in-house wiring works and is connected properly.
8	Repeat the steps above using a different ADSL port.

58.8 Testing Wiring

Use the following tests if there is no voice.

Systematically test wiring using a functioning telephone to determine if there is a wiring problem. If the connection is good, the telephone will return a dial tone. Letters in the figure shown next indicate the systematic tests to be done. Suppose you're using installation scenario "B" as shown in the chapter on MDF connections. The logic for other scenarios should be similar.

Use steps A-D if there is no voice but you can transmit data. Use all of the steps if there is no voice and you cannot transmit data.

Table 110 Wiring Tests

TEST	DESCRIPTION
A.	Test A determines if there is a wiring problem between the TELCO (telephone company) and MDF 1.
B.	Test B determines if there is a wiring problem between MDF 1 and MDF 2.
C.	Test C determines if there is a wiring problem between MDF 2 and your device.
D.	Test D determines if there is a problem with your device's internal splitter.
E.	Test E determines if there is a wiring problem between your device and MDF 3.
F.	Test F determines if there is a building-wiring problem between the subscriber's wall jack and MDF 3.

Figure 305 Testing In-house Wiring

Table 111 Testing In-house Wiring

STEP	TEST
A	Connect a standard telephone to MDF 1. If there is no dial tone, then a problem with the wire or wire connections between MDF 1 and the TELCO exists. Contact your telephone company for troubleshooting.
B	Connect a telephone to the upper port of MDF 2. If there is no dial tone, then the problem is between MDF 1 and MDF 2. Check the telephone wire and connections between MDFs 1 and 2.
C	Disconnect the telephone wire from CO. Connect a telephone to the telephone wire. If there is no dial tone, then the problem is between your device and MDF 2. Check the telephone wire's pin assignments (see Appendix C on page 449 for the proper pin assignments). Replace the telephone wire if the pin assignments are OK and there is still no dial tone.
D	Reconnect the telephone wire to CO. Disconnect the telephone wire from USER. Connect a telephone to USER (see Appendix C on page 449 for the proper pin assignments). If there is no dial tone, your device's internal splitter may be faulty, contact your vendor.
E	Reconnect the telephone wire to USERConnect a telephone to a lower port of MDF 3. If there is no dial tone, then the problem is between your device and MDF 3. Check the pin assignments of the telephone wire's connector that connects to USER. Replace the telephone wire connecting your device to MDF 3.If there is no dial tone, then MDF 3 may be faulty. Contact the telephone company if that is the case.
F	Disconnect the DSL modem from the wall jack and connect the telephone to the wall jack. If there is no dial tone, then there is a problem with the building wiring between the DSL subscriber's home and the MDF. Contact your telephone company for troubleshooting.

58.9 Local Server

The computer behind a DSL modem or router cannot access a local server connected to the IES-1248.

Table 112 Troubleshooting a Local Server

STEPS	CORRECTIVE ACTION
1	See Section 58.6 on page 433 to make sure that the subscriber is able to transmit to the IES-1248.
2	Make sure the computer behind the DSL device has the correct gateway IP address configured.
3	Check the VLAN configuration (see Chapter 19 on page 157).
4	Check the cable and connections between the IES-1248 and the local server.
5	Try to access another local server. If data can be transmitted to a different local server, the local server that could not be accessed may have a problem.

58.10 Data Rate

The SYNC-rate is not the same as the configured rate.

Table 113 Troubleshooting the SYNC-rate

STEPS	CORRECTIVE ACTION
1	Connect the ADSL modem or router directly to the ADSL port using a different telephone wire.
2	If the rates match, the quality of the telephone wiring that connects the subscriber to the ADSL port may be limiting the speed to a certain rate. If they do not match when a good wire is used, contact the distributor.

58.11 Configured Settings

The configured settings do not take effect.

Table 114 Troubleshooting the IES-1248's Configured Settings

CORRECTIVE ACTION

Use the “config save” command after you finish configuring to save the IES-1248’s settings.

58.12 Password

If you forget your password, you will need to use the console port to reload the factory-default configuration file (see Section 58.16 on page 438).

58.13 System Lockout

Any of the following could also lock you and others out from using in-band management (managing through the data ports).

1 Deleting the management VLAN (default is VLAN 1).
2 Incorrectly configuring the CPU VLAN.
3 Incorrectly configuring the access control settings.
4 Disabling all ports.

Note: Be careful not to lock yourself and others out of the system.

If you lock yourself (and others) out of the system, you can try using the console port to reconfigure the system. See Section 58.16 on page 438.

58.14 SNMP

The SNMP manager server cannot get information from the IES-1248.

Table 115 Troubleshooting the SNMP Server

STEPS	CORRECTIVE ACTION
1	Ping the IES-1248 from the SNMP server. If you cannot, check the cable, connections and IP configuration.
2	Check to see that the community (or trusted host) in the IES-1248 matches the SNMP server's community.
3	Make sure that your computer's IP address matches a configured trusted host IP address (if configured).
4	Incorrectly configuring the access control settings may lock you out from using in-band management. Try using the console port to reconfigure the system.

58.15 Telnet

I cannot telnet into the IES-1248.

Table 116 Troubleshooting Telnet

STEPS	CORRECTIVE ACTION
1	Make sure that the number of current telnet sessions does not exceed the maximum allowed number. You cannot have more than five telnet sessions at one time.
2	Make sure that your computer's IP address matches a configured secured client IP address (if configured). The IES-1248 immediately disconnects the telnet session if secured host IP addresses are configured and your computer's IP address does not match one of them.
3	Make sure that you have not disabled the Telnet service or changed the server port number that the IES-1248 uses for Telnet.
4	Ping the IES-1248 from your computer. If you are able to ping the IES-1248 but are still unable to telnet, contact the distributor. If you cannot ping the IES-1248, check the cable, connections and IP configuration.
5	Incorrectly configuring the access control settings may lock you out from using in-band management. Try using the console port to reconfigure the system.

58.16 Resetting the Defaults

If you lock yourself (and others) from the IES-1248, you will need to reload the factory-default configuration file. Uploading the factory-default configuration file replaces the current configuration file with the factory-default configuration file. This means that you will lose all previous configurations and the speed of the console port will be reset to the default of 9600bps with 8 data bit, no parity, one stop bit and flow control set to none. The user name will be reset to "admin" and the password will be reset to "1234" and the IP address to 192.168.1.1.

58.16.1 Resetting the Defaults Via Command

If you know the password, you can reload the factory-default configuration file via Command Line Interface (CLI) command. Use the following procedure.

1 Connect to the console port using a computer with terminal emulation software. See chapters 2-6 for details.

2 Enter your password.
3 Type config restore.
4 Type Y at the question "Do you want to restore default ROM file(y/n)?"
5 The IES-1248 restarts.

Figure 306 Resetting the Switch Via Command

ras> config restore   
System will reboot automatically after restoring default configuration. Do you want to proceed(y/n)? >   
restoring configuration...   
saving configuration to flash... 

The IES-1248 is now reinitialized with a default configuration file including the default user name of "admin" and the default password of "1234".

58.16.2 Uploading the Default Configuration File

If you forget your password or cannot access the IES-1248, you will need to reload the factory-default configuration file. Uploading the factory-default configuration file replaces the current configuration file with the factory-default configuration file. This means that you will lose all previous configurations and the speed of the console port will be reset to the default of 9600bps with 8 data bit, no parity, one stop bit and flow control set to none. The password will also be reset to "1234" and the IP address to 192.168.1.1.

Note: Uploading the factory default configuration file erases the IES-1248's entire configuration.

Obtain the default configuration file, unzip it and save it in a folder. Use a console cable to connect a computer with terminal emulation software to the IES-1248's console port. Turn the IES-1248 off and then on to begin a session. When you turn on the IES-1248 again you will see the initial screen. When you see the message Press any key to enter Debug Mode within 3 seconds press any key to enter debug mode.

To upload the configuration file, do the following:

1 Type atlc after the Enter Debug Mode message.
2 Wait for the Starting XMODEM upload message before activating XMODEM upload on your terminal.
