Introduction

Overview

The Vi30208 PoE switch, next generation network solutions, is an affordable managed switch that provides a reliable infrastructure for your business network. These switches deliver more intelligent features you need to improve the availability of your critical business applications, protect your sensitive information, and optimize your network bandwidth to deliver information and applications more effectively. Easy to set up and use,

it provides the ideal combination of affordability and capabilities for entry-level networking, including small business or enterprise applications. It also helps you create a more efficient and better-connected workforce.

The Vi30208 is an easy-to-implement managed Ethernet switch that provides ideal flexibility to design a suitable network infrastructure for business requirements. However, unlike other entry-level switching solutions that provide advanced managed network capabilities only in the most expensive models, all of Vigitron's series switches support the advanced security management capabilities and network features to support data, voice, security, and wireless technologies. These switches are easy to deploy and configure. They provide stable and quality performance network services your business needs.

The switch performs a wire-speed, non-blocking switching fabric. This allows wire-speed transport of multiple packets at low latency on all ports simultaneously. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

This switch uses store-and-forward technology to ensure maximum data integrity. With this technology, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.

The switch can also be managed over the network with a web browser or a Telnet application. The switch includes a built-in network management agent that allows it to be managed in-band by using SNMP or RMON (Groups 1, 2, 3, 9) protocols. It also has an RJ-45 console port connector on the front panel for out-of-band management.

Description of Hardware

The switch contains 8/10 1000BASE-T RJ-45 ports. All RJ-45 ports support automatic MDI/MDI-X operation, auto-negotiation, and IEEE 802.3x auto-negotiation of flow control, so the optimum data rate, and transmission can be selected automatically.

Vi30210 supports the Small Form Factor Pluggable (SFP) transceiver slots. The SFP transceiver slots are shared with RJ-45 port 9 to 10. In the default configuration, if an SFP transceiver (purchased separately) is installed in a slot and has a valid link on the port, the associated RJ-45 port is disabled.

The following table shows a list of transceiver types that have been tested with the switch. For an updated list of vendors supplying these transceivers, contact your local dealer. For information on the recommended standards for fiber optic cabling, see "1000 Mbps Gigabit Ethernet Collision Domain".

Network Planning

Introduction to Switching

A network switch allows simultaneous transmission of multiple packets. It can partition a network more efficiently than bridges or routers. Therefore, the switch has been recognized as one of the most important devices for today's networking technology.

When performance bottlenecks are caused by congestion at the network access point such as file server, the device can be connected directly to a switched port. By using the full-duplex mode, the bandwidth of the dedicated segment can be doubled to maximize throughput.

When networks are based on repeater (hub) technology, the distance between end stations is limited by a maximum hop count. However, a switch can subdivide the network into smaller and more manageable segments, and link them to the larger network. It then turns the hop count back to zero and removes the limitation.

A switch can easily be configured in any Ethernet, Fast Ethernet, or Gigabit Ethernet network to significantly increase bandwidth while using conventional cabling and network cards.

The Vi30208 has auto MDIX and 2 slots for the removable SFP module which support comprehensive types of fiber connection, such as LC and BiDi-LC modules. It is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below.

The switch is suitable for the following applications:

• Remote site application is used in enterprise or SMB.
• Peer-to-peer application is used in two remote offices.
• Office network.
  • High-performance requirement environment.
• Advance security for network safety application.
• Suitable for data/voice and video conference applications.

NOTE: Ports 5 and 6 are UTP ports capable of providing PoE and subject to all programmable features. Ports and 8 are fiber ports and provides transmission up to 2.5Gbps

Installing the Switch

Selecting a Site

The switch can be mounted using DIN Rail mounts equipment or operated using the rack mount kit or on a flat surface. Be sure to follow the guidelines below when choosing a location.

The site should:

• Be at the center of all the devices that you want to link and near a power outlet.
• Be able to maintain its temperature within -30^ to 70C (-30°C to 158^ ) and its humidity within 10% to 90% , non-condensing.
• Be accessible for installing, cabling, and maintaining the devices.
• Allow the status LEDs to be clearly visible.

Make sure the twisted-pair Ethernet cable is always routed away from power lines, radios, transmitters, or any other electrical interference.

Make sure the power supply that Vi30208 is connected to a separate grounded power supply that provides 100 to 240 VAC, 50 to 60 Hz.

Make sure the power supply you are using can provides the required power for your connected devices.

Ethernet Cabling

To ensure proper operation when installing the switch into a network, make sure that the current cables are suitable for 100BASE-TX or 1000BASE-T operation.

Check the following criteria against the current installation of your network:

Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cable with RJ-45 connectors; Category 5 or Category 5e with a maximum length of 100 meters is recommended 100BASE-TX, and Category 5e or 6 with a maximum length of 100 meters is recommended for 1000BASE-T.

Protection from radio frequency interference emissions.

Electrical surge suppression.

Separation of electrical wires and data-based network wiring.

Safe connections with no damaged cables, connectors, or shields.

Installing an Optional SFP Transceiver

You can install or remove a mini-GBIC SFP from a mini-GBIC slot without having to power off the switch. Use only manufacture mini-GBIC.

NOTE:

• The mini-GBIC slots are shared with the two 10/100/1000Base-T RJ-45 ports. If a mini-GBIC is installed in a slot, the associated RJ-45 port is disabled and cannot be used.
  • The mini-GBIC ports operate only at full-duplex. Half-duplex operation is not supported.
  • Ensure the network cable is NOT connected when you install or remove a mini-GBIC.
  •

CAUTION:

Use only supported genuine manufacture mini- GBICs with your switch. Non-manufacture mini-GBIC might have compatibility issues, and may result in product malfunction. SFPs should conform to the MSA standards.

Note: SFP transceivers are not provided in the switch package.

Connecting to the Console Port

The RJ-45 serial port on the switch's front panel is used to connect to the switch for out-of-band console configuration. The command-line-driven configuration program can be accessed from a terminal or a PC running a terminal emulation program. The pin assignments used to connect to the serial port are provided in the following table.

Making Network Connections

Connecting Network Devices

The switch is designed to be connected to 10, 100, or 1000Mbps network cards in PCs and servers, as well as, to other switches and hubs. It may also be connected to remote devices using optional SFP transceivers.

Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category or CAT 5e, or 6 cables for 1000BASE-T connections, and Category 5 or better for 100BASE-TX connections.

Cabling Guidelines- UTP Copper Cabling

The RJ-45 ports on the switch support automatic MDI/MDI-X pin-out configuration, so you can use standard straight-through or cross twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).

See Appendix B for further information on cabling.

CAUTION: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with RJ-45 connectors that conform to FCC standards.

Connecting to PCs, Servers, Hubs and Switches

Step 1: Attach one end of a Ethernet Cable to the device's RJ-45 connector.

Making Twisted-Pair Connections

Step 2: If the device is a network card and the switch is in the wiring closet, attach the other end of the Ethernet cable segment to a modular wall outlet that is connected to the wiring closet. See the section "Network Wiring Connections." Otherwise, attach the other end to an available port on the switch.

Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.

i

NOTE: Avoid using flow control on a port connected to a hub, unless it is actually required to solve a problem. Otherwise, back pressure jamming signals may degrade overall performance for the segment attached to the hub.

Step 3: The green LED notes both link and activity. When the link is 1G the amber LED will be lit.".

Network Wiring Connections

Today, the punch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment are as follows.

Step 1: Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel.

Step 2: If it's not already in place, attach one end of a cable segment to the back of the patch panel where the punch-down block is located and the other end to a modular wall outlet.

Step 3: Label the cables to simplify future troubleshooting. See "Cable Labeling and Connection Records" on page 29.

Making Fiber Port Connections

An optional Gigabit SFP transceiver can be used as a backbone connection between switches, or as a connection to a high-speed server.

Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends. Each multimode fiber optic port requires 50/125- or 62.5/125-micron multimode fiber optic cabling with an LC connector at both ends.

[Non-Text]

WARNING: This switch uses lasers to transmit signals over a fiber optic cable. The lasers are inherently eye-safe in normal operation. However, the user should never look directly at a transmit port when it is powered on.

[Non-Text]

WARNING: Considering safety, when selecting a fiber SFP device, please make sure that it can function at a temperature that is not less than the recommended maximum operating temperature of the product. You must also use an approved laser SFP transceiver.

Step 1: Remove and keep the LC port's rubber plug. When it's not connected to a fiber cable, the rubber plug should be replaced to protect the optics.

Step 2: Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.

Step 3: Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation.

Step 4: As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the connection is valid.

The fiber optic ports operate at 1 Gbps. The maximum length for fiber optic cable operating at Gigabit speed will depend on the fiber type as listed under "1000 Mbps Gigabit Ethernet Collision Domain" on page 27.

Connectivity Rules

1000Base-T Cable Requirements

When adding hubs to your network, please note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.

All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, provided that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations,

Category 5e or Category 6 cable should be used. The Category 5e and 6 specifications include test parameters that are only recommendations for

Category 5. Therefore, the first step in preparing the existing Category 5 cable to run 1000BASE-T is to make sure that it complies with the IEEE 802.3-2005 standards.

Cable Labeling and Connection Records

When planning a network installation, it is essential to label the opposing ends of cables and record where each cable is connected. This will allow the user to easily locate inter-connected devices, isolate faults, and change the topology without the need for unnecessary time consumption.

To best manage the physical implementations of your network, follow these guidelines:

• Clearly label the opposing ends of each cable.
• Use your building's floor plans to draw a map of the locations of all network-connected equipment. For each piece of equipment, identify the devices to which it is connected.
  • Note the length of each cable and the maximum cable length supported by the switch ports.
  • For ease of understanding, use a location-based key when assigning prefixes to your cable labeling.
  • Use sequential numbers for cables that originate from the same equipment.
• Differentiate between racks by naming accordingly.
• Label each separate piece of equipment.
  • Display a copy of your equipment map, including keys to all abbreviations at each equipment rack.

Basic Troubleshooting Tips

Most problems are caused by the following situations. Check for these items first when starting your troubleshooting:

Connecting to devices that have a fixed full-duplex configuration.

The RJ-45 ports are configured as "Auto". When connecting to the attached devices, the switch will operate in one of two ways to determine the link speed and the communication mode (half-duplex or full-duplex):

• If the connected device is also configured to "Auto", the switch will automatically negotiate both link speed and communication mode.
• If the connected device has a fixed configuration (e.g., 100Mbps at half or full duplex), the switch will automatically sense the link speed but will default to a communication mode of half-duplex.

Because the series Vi30208 behave in this way (in compliance with the IEEE802.3 standard), if a device connected to the switch has a fixed configuration at full duplex, the device will not connect correctly to the switch. The result will be high error rates and very inefficient communications between the switch and the device. Make sure all devices connected to the Vi30208 are configured to auto negotiate, or are configured to connect at half-duplex (e.g. all hubs are configured this way).

• Faulty or loose cables. Look for loose or faulty connections. If they appear to be OK, make sure the connections are snug. If that does not correct the problem, try a different cable.
• Non-standard cables. Non-standard and miswired cables may cause network collisions and other network problems, and can seriously impair network performance. Use a new correctly-wired cable for pin-outs and correct cable wiring. A category 5 cable tester is a recommended tool for every 100Base-TX and 1000Base-T network installation.
• Improper Network Topologies. It is important to make sure you have a valid network topology. If you no longer experience the problems, the new topology is probably at fault. In addition, you should make sure that your network topology contains no data path loops.
• Check the port configuration. A port on your switch may not be operating as you expect because it has been put into a "blocking" state by the Spanning Tree, the GVRP (automatic VLANs), or the LACP (automatic trunking). Note that the normal operation of the Spanning Tree, GVRP, and LACP features may put the port into a blocking state. Or, the port just may have been configured as
• "Disabled" through software.

Basic Troubleshooting Chart

Symptom	Action
POWER LED is Off	○ Check connections between the switch, the power cord, and the wall outlet.○ Contact your dealer for assistance.
Link LED is Off	○ Verify that the switch and attached device are powered on.○ Be sure the cable is plugged into the switch and corresponding device.○ If the switch is installed in a rack, check theconnections to the punch-down block and the patch panel.○ Verify that the proper cable type is used and its length does not exceed specified limits.○ Check the adapter on the attached device and cable○ connections for possible defects. Replace the defective adapter or cable if necessary.

If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses, or surges at the power outlet. If you still cannot isolate the problem, the internal power supply may be defective. Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (e.g. the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

You can access the management agent in the switch from anywhere within the attached network using Telnet, a web browser. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you've entered the correct IP address. Also, be sure the port that you are connecting to the switch has not been disabled. If it has not been disabled, then check the network cabling that runs between your remote location and the switch.

IP Addressing: In order to access the Vi30208's GUI, your connected computer must be on the same network as the switch. As the default IP address is 192.168.1.130, the computer you use can be addressed as 192.168.1.xxx (any number except (130).

Power and Cooling Problems

Installation

The Vi30208 can operate under high temperature ranging from -30C to 70C. The unit is not weatherproof and requires installation in weatherproof housing. Consideration must be given to the possibility of the Vi30208 internal temperature exceeding the ratings specified in the users manual.

The Vi30208 does provide operation settings which monitor the switches internal temperature and will affect individual port shut downs based on the actual settings. It is recommended these settings not exceed 115C.

Cables

Twisted-Pair Cable and Pin Assignment

For 10/100BASE-TX connections, the twisted-pair cable must have two pairs of wires. For 1000BASE-T connections, the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.

CAUTION: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

CAUTION: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.

The figure below illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.

Diagram of two Ethernet connectors with labeled pins (no text or symbols beyond labels)

Figure 19: RJ-45 Connector Pin Numbers

10BASE-T/100Base-Tx Pin Assignments

Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also, be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).

The RJ-45 ports on the switch base unit support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable. When using any RJ-45 port on this switch, you can use either a straight-through or crossover cable.

Pin	MDI Signal Name	MDI-X Signal Name
1	Transmit Data plus (TD+)	Receive Data plus (RD+)
2	Transmit Data minus (TD-)	Receive Data minus (RD-)
3	Receive Data plus (RD+)	Transmit Data plus (TD+)
6	Receive Data minus (RD-)	Transmit Data minus (TD-)
4,5,7,8	Not used	Not used

NOTE: The "+" and "-" signs represent the polarity of the wires that make up each wire pair.

EIA/TIA 568B RJ-45 Wiring Standard

Straight-Through Wiring

If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through (when auto-negotiation is enabled for any RJ-45 port on this switch, you can use either straight-through or crossover cable to connect to any device type).

You must connect all four wire pairs as shown in the following diagram to support Gigabit Ethernet.

If your existing Category 5 installation does not meet one of the test parameters for 1000Base-T, there are three measures that can be applied to try and correct the problem:
Replace any Category 5 patch cables with high-performance Category 5e or Catgory 6 cables. Reduce the number of connectors used in the link. Reconnect some of the connectors in the link.

1000BASE-T MDI and MDI-X Port Pin-Out
All 1000BASE-T ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs.
The table below shows the 1000BASE-T MDI and MDI-X port pin outs. These ports require that all four pairs of wires be connected. Note that for 1000BASE-T operation, all four pairs of wires are used for both transmit and receive.
Use 100-ohm Category 5, 5e, or 6 unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for 1000BASE-T connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 ft).

(NEXT), and Far-End Crosstalk (FEXT). This cable testing information is specified in the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test

parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, "The Additional Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.

NOTE: That when testing your cable installation, be sure to include all patch cables between switches and end devices.

Fiber Standards

Important Note: Fiber SFPs have no standards regarding interface with network switches with the exception of the Multi standard Agreement (MSA) with is limited to the physical interface between the SFP and a switch port. Data transmission may require adjusting port bandwidth settings on your switch.

When installing SFP match certain the SFP matches the installed fiber and are the same on both ends of the cable

The International Telecommunication Union (ITU-T) has standardized various fiber types for data networks. These are summarized in the following table.

Fiber Standards

2.2.2 Port Power Savings

Port Power Savings Configuration

Port Configuration

Port Power Saving Configuration Dialog

• Port Power Saving Configuration:

- Optimize EEE for: The devise can be set for Optimize EEE, to achieving the best power saving or lowest traffic delays.

Power Enable the EEE function. This's defaulted setting.

- Latency: Disable the EEE function.

- Port Configuration

- ② ActiPHY: t's working by reducing the port power without a connection. The port is started within a short time to check whether the ethernet cable is inserted. It also can save power for those ports that aren't cable-connected.

③ EEE (Green ethernet): EEE is a power saving option. It can reduce the power use under the condition of low or no traffic. EEE is developed by ieee802.3 az team of IEEE. It works to close the circuit when there's no traffic. All the circuits are started when one port gets data transmission. The started time for circuit is called arousing time. The arousing time is defaulted as 17-connected of 1Gbit and 30-connected speed. To make sure all the circuits can be supplied from the switch transceiver, EEE devise must be consistent with the value of arousing time. These devises can transmit the arousing time information via LLDP. The port is negotiated for 1G or 100Mbit full-duplex mode while EEE is working in the mode of auto-negotiation. The EEE cannot be started and the related check box is gray when the port without EEE. When one port is closed to save power, the output traffic is saved in the buffer until the port is restarted. Some traffic will be happened while closing the port and upping, that'll save more power to transmit mass traffic if it can be buffered. The buffered traffic will be result in some transmission delay. Traffic that should not be blocked can be assigned in urgent queue to reduce delay, but still saving power generally.

- ⑤ EEE Emergency Queue: It minimizes the delay for a particular frame and then marks the queue as an emergency one by mapping a frame to a specific queue (using QOS). When an emergency queue obtains data transmission, the circuit will start immediately and the delay will be shortened to arousing time. Once the data is available, the queue set will activate the transmission of the frame. Otherwise, the queue will delay transmission until the Frame can be transmitted.

Ports Configuration

Port Configuration

A. Description: The description of the port. It is an ASCII string no longer than 256 characters.
B. Link: The current link state is displayed graphically. Green indicates the link is up and red that it is down.
C. Speed: The working modes of the configured ports are as below:

a. Disabled
b. Auto: The Auto mode is defaulted by system.
c. 10Mbps HDX
d. 10Mbps FDX100Mbps HDX
e. 100Mbps FDX
f. 1Gbps FDX

D. 2.5Gbps FDX. Only the fiber port can configure 2.5Gbps FDX.

E. Adv Duplex: When duplex is set as auto i.e auto negotiation, the port will only advertise the specified duplex as either Fdx or Hdx to the link partner. By default, port will advertise all the supported duplexes if the Duplex is Auto.
F. Adv speed: When Speed is set as auto i.e auto negotiation, the port will only advertise the specified speeds (10M100M1G) to the link partner. By default, port will advertise all the supported speeds if speed is set as Auto.
G. Flow Control: When Auto Speed is selected on a port, this section indicates the flow control capability that is advertised to the link partner.

When a fixed-speed setting is selected, that is what is used. The Current Rx column indicates whether pause frames on the port are obeyed, and the Current Tx column indicates whether pause frames on the port are transmitted. The Rx and Tx settings are determined by the result of the last Auto Negotiation.

Check the configured column to use flow control. This setting is related to the setting for Configured Link Speed. NOTICE: The 100FX standard doesn't support Auto Negotiation, so when in 100FX mode the flow control capabilities will always be shown as "disabled".

H. Maximum Frame Size: Enter the maximum frame size allowed for the switch port, including FCS. The range is 1518-9600 bytes.

a. Excessive Collision Mode Configure port transmit collision behavior.
b. Discard : Discard frame after 16 collisions (default).
c. Restart : Restart backoff algorithm after 16 collisions.

I. Frame Length Check: Configures if frames with incorrect frame length in the EtherType/Length field shall be dropped. An Ethernet frame contains a field EtherType which can be used to indicate the frame payload size (in bytes) for values of 1535 and below. If the EtherType/Length field is above 1535, it indicates that the field is used as an EtherType (indicating which protocol is encapsulated in the payload of the frame). If "frame length check" is enabled, frames with payload size less than 1536 bytes are dropped, if the EtherType/Length field doesn't match the actually payload length. If "frame length check" is disabled, frames are not dropped due to frame length mismatch. Note: No drop counters count frames dropped due to frame length mismatch.

Save | Reset

System Configuration

A. Mode: Enable or disable the Global Port Security Limit Control.

a. If globally disabled, other modules may still use the underlying function, but the limit check and corresponding actions are disabled.

B. Aging Enabled: If enabled, the safe MAC address will get ager as it ages.

a. As the growing of age, the timer will be enabled as soon as the end host is protected. When the timer is expired, the switch begins looking for Frames from the end host. If such a Frame is not visible in the next aging cycle, the end host is considered to be disconnected and the corresponding resource is released on the switch.

C. Aging Period: If Aging Enabled is checked, then the aging period is controlled with this input. If other modules are using the underlying port security for securing MAC addresses, they may have other requirements to the aging period. The underlying port security will use the shorter requested aging period of all modules that use the functionality.

a. The Aging Period can be set to a number between 10 and 10,000,000 seconds.

b. To understand why aging may be desired, consider the following scenario: Suppose an end-host is connected to a 3rd party switch or hub, which in turn is connected to a port on this switch on which Limit Control is enabled. The end-host will be allowed to forward if the limit is not exceeded. Now suppose that the end-host logs off or powers down. If it wasn't for aging, the end-host would still take up resources on this switch and will be allowed to forward. To overcome this situation, enable aging. With aging enabled, a timer is started once the end-host gets secured. When the timer expires, the switch starts looking for frames from the end-host, and if such frames are not seen within the next Aging Period, the end-host is assumed to be disconnected, and the corresponding resources are freed on the switch.

Port Configuration

A. Port: It indicates the port number.

B. Mode: Enable or disable Port Security Limit Control on each port. In order to let it work, the Port Security Limit Control needs to be enabled globally and on the port.

C. Limit: It indicates that the max number of MAC addresses that can be protected on this port. This number cannot exceed 1024.

a. If the limitation is exceeded, take the appropriate action.

D. Action: If Limit is reached, the switch can take one of the following actions:

E. None: Do not allow more than Limit MAC addresses on the port, but take no further action.

F. Trap: If Limit + 1 MAC addresses is seen on the port, send an SNMP trap. If Aging is disabled, only one SNMP trap will be sent, but with Aging enabled, new SNMP traps will be sent every time the limit gets exceeded.

G. shutdown: If Limit + 1 MAC addresses is seen on the port, shut down the port. This implies that all secured MAC addresses will be removed from the port, and no new address will be learned. Even if the link is physically disconnected and reconnected on the port (by

disconnecting the cable), the port will remain shut down. There are three ways to re-open the port:

1. Boot the switch,
2. Disable and re-enable Limit Control on the port or the switch,
3. Click the Reopen button.

H. Trap & Shutdown: If Limit + 1 MAC addresses is seen on the port, both the "Trap" and the "Shutdown" actions described above will be taken.

I. State: This column shows the current state of the port as seen from the Limit Control's point of view. The state takes one of four values:

1. Disabled: Limit Control is either globally disabled or disabled on the port
2. Ready: The limit is not yet reached. This can be shown for all actions
3. Limit Reached: Indicates that the limit is reached on this port. This state can only be shown if Action is set to None or Trap.
4. Shutdown: Indicates that the port is shut down by the Limit Control module. This state can only be shown if Action is set to Shutdown or Trap & Shutdown

NAS configuration

System Configuration

Mode

Indicates if NAS is globally enabled or disabled on the switch. If globally disabled, all ports are allowed forwarding of frames.

Reauthentication Enabled

If checked, successfully authenticated supplicants/clients are reauthenticated after the interval specified by the Reauthentication Period. Reauthentication for 802.1X-enabled ports can be used to detect if a new device is plugged into a switch port or if a supplicant is no longer attached. For MAC-based ports, reauthentication is only useful if the RADIUS server configuration has changed. It does not involve communication between the switch and the client, and therefore doesn't imply that a client is still present on a port (see Aging Period below).

Reauthentication Period

Determines the period, in seconds, after which a connected client must be reauthenticated. This is only active if the Reauthentication Enabled checkbox is checked. Valid values are in the range 1 to 3600 seconds.

EAPOL Timeout

Determines the time for retransmission of Request Identity EAPOL frames.

Valid values are in the range 1 to 65535 seconds. This has no effect for MAC-based ports.

Aging Period

This setting applies to the following modes, i.e. modes using the Port Security functionality to secure MAC addresses:

- Single 802.1X

- Multi 802.1X

- MAC-Based Auth.

When the NAS module uses the Port Security module to secure MAC addresses, the Port Security module needs to check for activity on the MAC address in question at regular intervals and free resources if no activity is seen within a given period of time. This parameter controls exactly this period and can be set to a number between 10 and 1000000 seconds.

If reauthentication is enabled and the port is in an 802.1X-based mode, this is not so critical, since supplicants that are no longer attached to the port will get removed upon the next reauthentication, which will fail. But if reauthentication is not enabled, the only way to free resources is by aging the entries.

For ports in MAC-based Auth. mode, reauthentication doesn't cause direct communication between the switch and the client, so this will not detect whether the client is still attached or not, and the only way to free any resources is to age the entry.

Hold Time

This setting applies to the following modes, i.e. modes using the Port Security functionality to secure MAC addresses:

- Single 802.1X

- Multi 802.1X

- MAC-Based Auth.

If a client is denied access - either because the RADIUS server denies the client access or because the RADIUS server request times out (according to the timeout specified on the

"Configuration→Security→AAA" page) - the client is put on hold in the Unauthorized state. The hold timer does not count during an on-going authentication.

In MAC-based Auth. mode, the switch will ignore new frames coming from the client during the hold time.

The Hold Time can be set to a number between 10 and 1000000 seconds.

RADIUS-Assigned QoS Enabled

RADIUS-assigned QoS provides a means to centrally control the traffic class to which traffic coming from a successfully authenticated supplicant is assigned on the switch. The RADIUS server must be configured to transmit special RADIUS attributes to take advantage of this feature (see RADIUS-Assigned QoS Enabled below for a detailed description).

The "RADIUS-Assigned QoS Enabled" checkbox provides a quick way to globally enable/disable RADIUS-server assigned QoS Class functionality. When checked, the individual ports' ditto setting determines whether RADIUS-assigned QoS Class is enabled on that port. When unchecked, RADIUS-server assigned QoS Class is disabled on all ports.

RADIUS-Assigned VLAN Enabled

RADIUS-assigned VLAN provides a means to centrally control the VLAN on which a successfully authenticated supplicant is placed on the switch. Incoming traffic will be classified to and switched on the RADIUS-assigned VLAN. The RADIUS server must be configured to transmit special RADIUS attributes to take advantage of this feature (see RADIUS-Assigned VLAN Enabled below for a detailed description).

The "RADIUS-Assigned VLAN Enabled" checkbox provides a quick way to globally enable/disable RADIUS-server assigned VLAN functionality. When checked, the individual ports' ditto setting determines whether RADIUS-assigned VLAN is enabled on that port. When unchecked, RADIUS-server assigned VLAN is disabled on all ports.

Guest VLAN Enabled

A Guest VLAN is a special VLAN - typically with limited network access - on which 802.1X-unaware clients are placed after a network administrator-defined timeout. The switch follows a set of rules for entering and leaving the Guest VLAN as listed below.

The "Guest VLAN Enabled" checkbox provides a quick way to globally enable/disable Guest VLAN functionality. When checked, the individual ports' ditto setting determines whether the port can be moved into Guest VLAN. When unchecked, the ability to move to the Guest VLAN is disabled on all ports.

Guest VLAN ID

This is the value that a port's Port VLAN ID is set to if a port is moved into the Guest VLAN. It is only changeable if the Guest VLAN option is globally enabled.

Valid values are in the range [1; 4095].

Max. Reauth. Count

The number of times the switch transmits an EAPOL Request Identity frame without response before considering entering the Guest VLAN is adjusted with this setting. The value can only be changed if the Guest VLAN option is globally enabled.

Valid values are in the range [1; 255].

Allow Guest VLAN if EAPOL Seen

The switch remembers if an EAPOL frame has been received on the port for the life-time of the port. Once the switch considers whether to enter the Guest VLAN, it will first check if this option is enabled or disabled. If disabled (unchecked; default), the switch will only enter the Guest VLAN if an EAPOL frame has not been received on the port for the life-time of the port. If enabled (checked), the switch will consider entering the Guest VLAN even if an EAPOL frame has been received on the port for the life-time of the port.

The value can only be changed if the Guest VLAN option is globally enabled.

Port Configuration

Port

The port number for which the configuration below applies.

Admin State

If NAS is globally enabled, this selection controls the port's authentication mode. The following modes are available:

- Force Authorized

In this mode, the switch will send one EAPOL Success frame when the port link comes up, and any client on the port will be allowed network access without authentication.

- Force Unauthorized

In this mode, the switch will send one EAPOL Failure frame when the port link comes up, and any client on the port will be disallowed network access.

- Port-based 802.1X

In the 802.1X-world, the user is called the supplicant, the switch is the authenticator, and the RADIUS server is the authentication server. The authenticator acts as the man-in-the-middle, forwarding requests and responses between the supplicant and the authentication server. Frames sent between the supplicant and the switch are special 802.1X frames, known as EAPOL (EAP Over LANs) frames. EAPOL frames encapsulate EAP PDUs (RFC3748). Frames sent between the switch and the RADIUS server are RADIUS packets. RADIUS packets also encapsulate EAP PDUs together with other attributes like the switch's IP address, name, and the supplicant's port number on the switch. EAP is very flexible, in that it allows for different authentication methods, like MD5-Challenge, PEAP, and TLS. The important thing is that the authenticator (the switch) doesn't need to know which authentication method the supplicant and the authentication server are using, or how many information exchange frames are needed for a particular method. The switch simply encapsulates the EAP part of the frame into the relevant type (EAPOL or RADIUS) and forwards it.

When authentication is complete, the RADIUS server sends a special packet containing a success or failure indication. Besides forwarding this decision to the supplicant, the switch uses it to open up or block traffic on the switch port connected to the supplicant.

Note: Suppose two backend servers are enabled and that the server timeout is configured to X seconds (using the AAA configuration page), and suppose that the first server in the list is currently down (but not considered dead). Now, if the supplicant retransmits EAPOL Start frames at a rate faster than X seconds, then it will never get authenticated because the switch will cancel on-going backend authentication server requests whenever it receives a new EAPOL Start frame from the supplicant. And since the server hasn't yet failed (because the X seconds haven't expired), the same server will be contacted upon the next backend authentication server request from the switch. This scenario will loop forever. Therefore, the server timeout should be smaller than the supplicant's EAPOL Start frame retransmission rate.

- Single 802.1X

In port-based 802.1X authentication, once a supplicant is successfully authenticated on a port, the whole port is opened for network traffic. This allows other clients connected to the port (for instance through a hub) to piggy-back on the successfully authenticated client and get network access even though they really aren't authenticated. To overcome this security breach, use the Single 802.1X variant.

Single 802.1X is really not an IEEE standard, but features many of the same characteristics as does port-based 802.1X. In Single 802.1X, at most one supplicant can get authenticated on the port at a time. Normal EAPOL frames are used in the communication between the supplicant and the switch. If more than one supplicant is connected to a port, the one that comes first when the port's link comes up will be the first one considered. If that supplicant doesn't provide valid credentials within a certain amount of time, another supplicant will get a chance. Once a supplicant is successfully authenticated, only that supplicant will be allowed access. This is the most secure of all the supported modes. In this mode, the Port Security module is used to secure a supplicant's MAC address once successfully authenticated.

- Multi 802.1X

- Multi 802.1X is - like Single 802.1X - not an IEEE standard, but a variant that features many of the characteristics. In Multi 802.1X, one or more supplicants can get authenticated on the same port at the same time. Each supplicant is authenticated individually and secured in the MAC table using the Port Security module.

In Multi 802.1X it is not possible to use the multicast BPDU MAC address as destination MAC address for EAPOL frames sent from the switch towards the supplicant, since that

would cause all supplicants attached to the port to reply to requests sent from the switch. Instead, the switch uses the supplicant's MAC address, which is obtained from the first EAPOL Start or EAPOL Response Identity frame sent by the supplicant. An exception to this is when no supplicants are attached. In this case, the switch sends EAPOL Request Identity frames using the BPDU multicast MAC address as destination - to wake up any supplicants that might be on the port.

The maximum number of supplicants that can be attached to a port can be limited using the Port Security Limit Control functionality.

- MAC-based Auth.

Unlike port-based 802.1X, MAC-based authentication is not a standard, but merely a best-practices method adopted by the industry. In MAC-based authentication, users are called clients, and the switch acts as the supplicant on behalf of clients. The initial frame (any kind of frame) sent by a client is snooped by the switch, which in turn uses the client's MAC address as both username and password in the subsequent EAP exchange with the RADIUS server. The 6-byte MAC address is converted to a string on the following form "xx-xx-xx-xx-xx-xx", that is, a dash (-) is used as separator between the lower-cased hexadecimal digits. The switch only supports the MD5-Challenge authentication method, so the RADIUS server must be configured accordingly.

When authentication is complete, the RADIUS server sends a success or failure indication, which in turn causes the switch to open up or block traffic for that particular client, using the Port Security module. Only then will frames from the client be forwarded on the switch. There are no EAPOL frames involved in this authentication, and therefore, MAC-based Authentication has nothing to do with the 802.1X standard.

The advantage of MAC-based authentication over 802.1X-based authentication is that the clients don't need special supplicant software to authenticate. The disadvantage is that MAC addresses can be spoofed by malicious users - equipment whose MAC address is a valid RADIUS user can be used by anyone. Also, only the MD5-Challenge method is supported. The maximum number of clients that can be attached to a port can be limited using the Port Security Limit Control functionality.

RADIUS-Assigned QoS Enabled

When RADIUS-Assigned QoS is both globally enabled and enabled (checked) on a given port, the switch reacts to QoS Class information carried in the RADIUS Access-Accept packet transmitted by the RADIUS server when a supplicant is successfully authenticated. If present and valid, traffic received on the supplicant's port will be classified to the given QoS Class. If (re-)authentication fails or the RADIUS Access-Accept packet no longer carries a QoS Class or it's invalid, or the supplicant is otherwise no longer present on the port, the port's QoS Class is immediately reverted to the original QoS Class (which may be changed by the administrator in the meanwhile without affecting the RADIUS-assigned).

This option is only available for single-client modes, i.e.

• Port-based 802.1X
- Single 802.1X

RADIUS attributes used in identifying a QoS Class:

The User-Priority-Table attribute defined in RFC4675 forms the basis for identifying the QoS Class in an Access-Accept packet.

Only the first occurrence of the attribute in the packet will be considered, and to be valid, it must follow this rule:

- All 8 octets in the attribute's value must be identical and consist of ASCII characters in the range '0' - '7', which translates into the desired QoS Class in the range [0; 7].

RADIUS-Assigned VLAN Enabled

When RADIUS-Assigned VLAN is both globally enabled and enabled (checked) for a given port, the switch reacts to VLAN ID information carried in the RADIUS Access-Accept packet transmitted by the RADIUS server when a supplicant is successfully authenticated. If present and valid, the port's Port VLAN ID will be changed to this VLAN ID, the port will be set to be a member of that VLAN ID, and the port will be forced into VLAN unaware mode. Once assigned, all traffic arriving on the port will be classified and switched on the RADIUS-assigned VLAN ID.

If (re-)authentication fails or the RADIUS Access-Accept packet no longer carries a VLAN ID or it's invalid, or the supplicant is otherwise no longer present on the port, the port's VLAN ID is immediately reverted to the original VLAN ID (which may be changed by the administrator in the meanwhile without affecting the RADIUS-assigned).

This option is only available for single-client modes, i.e.

• Port-based 802.1X
• Single 802.1X

For trouble-shooting VLAN assignments, use the "Monitor→VLANs→VLAN Membership and VLAN Port" pages. These pages show which modules have (temporarily) overridden the current Port VLAN configuration.

RADIUS attributes used in identifying a VLAN ID:

RFC2868 and RFC3580 form the basis for the attributes used in identifying a VLAN ID in an Access-Accept packet. The following criteria are used:

• The Tunnel-Medium-Type, Tunnel-Type, and Tunnel-Private-Group-ID attributes must all be present at least once in the Access-Accept packet.
• The switch looks for the first set of these attributes that have the same Tag value and fulfil the following requirements (if Tag == 0 is used, the Tunnel-Private-Group-ID does not need to include a Tag):

○ Value of Tunnel-Medium-Type must be set to "IEEE-802" (ordinal 6).
○ Value of Tunnel-Type must be set to "VLAN" (ordinal 13).
Value of Tunnel-Private-Group-ID must be a string of ASCII chars in the range '0' - '9', which is interpreted as a decimal string representing the VLAN ID. Leading '0's are discarded. The final value must be in the range [1; 4095].

Guest VLAN Enabled

When Guest VLAN is both globally enabled and enabled (checked) for a given port, the switch considers moving the port into the Guest VLAN according to the rules outlined below.

This option is only available for EAPOL-based modes, i.e.:

• Port-based 802.1X
• Single 802.1X
• Multi 802.1X

For trouble-shooting VLAN assignments, use the "Monitor→VLANs→VLAN Membership and VLAN Port" pages. These pages show which modules have (temporarily) overridden the current Port VLAN configuration.

Guest VLAN Operation:

When a Guest VLAN enabled port's link comes up, the switch starts transmitting EAPOL Request Identity frames. If the number of transmissions of such frames exceeds Max. Reauth. Count and no EAPOL frames have been received in the meanwhile, the switch considers entering the Guest VLAN. The interval between transmission of EAPOL Request Identity frames is configured with EAPOL Timeout. If Allow Guest VLAN if EAPOL Seen is enabled, the port will now be placed in the Guest VLAN. If disabled, the switch will first check its history to see if an EAPOL frame has previously been received on the port (this history is cleared if the port link goes down or the port's Admin State is changed), and if not, the port will be placed in the Guest VLAN. Otherwise, it will not move to the Guest VLAN, but continue transmitting EAPOL Request Identity frames at the rate given by EAPOL Timeout.

Once in the Guest VLAN, the port is considered authenticated, and all attached clients on the port are allowed access on this VLAN. The switch will not transmit an EAPOL Success frame when entering the Guest VLAN.

While in the Guest VLAN, the switch monitors the link for EAPOL frames, and if one such frame is received, the switch immediately takes the port out of the Guest VLAN and starts authenticating the supplicant according to the port mode. If an EAPOL frame is received, the port will never be able to go back into the Guest VLAN if the "Allow Guest VLAN if EAPOL Seen" is disabled.

Port State

The current state of the port. It can undertake one of the following values:

• Globally Disabled: NAS is globally disabled.

• Link Down: NAS is globally enabled, but there is no link on the port.
• Authorized: The port is in Force Authorized or a single-supplicant mode and the supplicant is authorized.
• Unauthorized: The port is in Force Unauthorized or a single-supplicant mode and the supplicant is not successfully authorized by the RADIUS server.
• X Auth/Y Unauth: The port is in a multi-supplicant mode. Currently X clients are authorized and Y are unauthorized.

Restart

Two buttons are available for each row. The buttons are only enabled when authentication is globally enabled and the port's Admin State is in an EAPOL-based or MAC-based mode.

Clicking these buttons will not cause settings changed on the page to take effect.

• Reauthenticate: Schedules a reauthentication whenever the quiet-period of the port runs out (EAPOL-based authentication). For MAC-based authentication, reauthentication will be attempted immediately.
  The button only has effect for successfully authenticated clients on the port and will not cause the clients to get temporarily unauthorized.
  • Reinitialize: Forces a reinitialization of the clients on the port and thereby a reauthentication immediately. The clients will transfer to the unauthorized state while the reauthentication is in progress.

Aggregation

2.7 Aggregation

Compared to adding extra cables to increase redundancy and link speed, link aggregation is a relatively inexpensive way to build a high-speed main network that transmits more datas than any portor device can transmit. Link aggregation uses multiple ports to increase link speed in parallel. It aggregates multiple physical ports into one logical channel, you can use static aggregation or negotiate with the LACP protocol. There are two types of aggregations, "static" and "LACP". And two main icons under the aggregate heading, they are static and LACP.

The LACP protocol is used, the port aggregation is performed only the peer and port connected to the port negotiates with the local port. The first condition for a port to be aggregated is that the port must be Linkup, and the port negotiates a full-duplex mode. During the aggregation process, the speeds of all physical member ports must be the same. That is, if one physical port has been successfully aggregated, the speed of the second physical port must be the same as the speed of the physical port that has been successfully aggregated. Similarly, the VALN attributes of all physical ports and aggregated ports must also be consistent. LACP provides two aggregation methods, one is Active and the other is Passive. In Active mode, the switch initiates the aggregation negotiation process, and the Passive mode passively accepts the aggregation negotiation process. When selecting LACP aggregation, if the Passive modes are used on both sides of the port aggregation, the aggregation will not succeed because both sides will wait for the peer to initiate the aggregation negotiation process.

Port

The switch port number.

LACP Enabled

Controls whether LACP is enabled on this switch port. LACP will form an aggregation when 2 or more ports are connected to the same partner.

Key

The Key value incurred by the port, range 1-65535. The Auto setting will set the key as appropriate by the physical link speed, 10Mb = 1 , 100Mb = 2 , 1Gb = 3 . Using the Specific setting, a user-defined value can be entered. Ports with the same Key value can participate in the same aggregation group, while ports with different keys cannot.

Role

The Role shows the LACP activity status. The Active will transmit LACP packets each second, while Passive will wait for a LACP packet from a partner (speak if spoken to).

Timeout

The Timeout controls the period between BPDU transmissions. Fast will transmit LACP packets each second, while Slow will wait for 30 seconds before sending a LACP packet.

Prio

The Prio controls the priority of the port, range 1-65535. If the LACP partner wants to form a larger group than is supported by this device then this parameter will control which ports will be active and which ports will be in a backup role. Lower number means greater priority.

Port

The switch port number.

OAM Enabled

Controls whether Link OAM is enabled on this switch port. Enabling Link OAM provides the network operators the ability to monitor the health of the network and quickly determine the location of failing links or fault conditions.

OAM Mode

Configures the OAM Mode as Active or Passive. The default mode is Passive.

• Active mode

DTE's configured in Active mode initiate the exchange of Information OAMPDUs as defined by the Discovery process. Once the Discovery process completes, Active DTE's are permitted to send any OAMPDU while connected to a remote OAM peer entity in Active mode. Active DTE's operate in limited respect if the remote OAM entity is operating in Passive mode. Active devices should not respond to OAM remote loopback commands and variable requests from a Passive peer.

- Passive mode

DTE's configured in Passive mode do not initiate the Discovery process. Passive DTE's react to the initiation of the Discovery process by the remote DTE. This eliminates the possibility of passive-to-passive links. Passive DTE's shall not send Variable Request or Loopback Control OAMPDUs.

Loopback Support

Controls whether the loopback support is enabled for the switch port. Link OAM remote loopback can be used for fault localization and link performance testing. Enabling the loopback support will allow the DTE to execute the remote loopback command that helps in the fault detection.

Link Monitor Support

Controls whether the Link Monitor support is enabled for the switch port. On enabling the Link Monitor support, the DTE supports event notification that permits the inclusion of diagnostic information.

MIB Retrieval Support

Controls whether the MIB Retrieval Support is enabled for the switch port. On enabling the MIB retrieval support, the DTE supports polling of various Link OAM based MIB variables' contents.

Spanning Tree

2.10 Spanning Tree

For some web services, an always-online connection is required to ensure the online activity of end-useris not interrupted by unexpected interruptions. In this case, multiple active paths between network nodes are established to prevent interruptions.

However, there are high trends in the interconnection of multipaths, resulting in network instability and making the network disabled in the worst case. For example, a MAC address table that used by a switch or bridge may fail because the same MAC address (and the same Web host) is visible on multiple ports. Second, a broadcast storm occurs. This is caused by broadcast packets transmitted in an endless loop between switches. A broadcast storm can consume all available CPU resources and bandwidth. To solve the problem caused by the bridging loop, the spanning tree allows the network design to contain redundant links, if the active link fails, the risk of bridging loops is not required, or the backup links need to be manually enabled/disabled to provide an automatic backup path.

The Spanning Tree Protocol (STP) is defined from IEEE Standard 802.1 that can create a spanning tree in the mesh network of the connected Layer-2 bridge (usually it's an Ethernet switch) and disable links that do not belong to the tree. An active path is left between any two network nodes. In order to provide faster spanning tree convergence after the topological changes, the evolution of the cross-tree protocol "Rapid Spanning Tree Protocol (RSTP)" was introduced by IEEE 802.1 w. RSTP is an improvement of STP; therefore, it has basic operational characteristics. This fundamentally creates a chain effect. From Root Bridge, each designated bridge makes recommendations to its neighbors to determine whether it can make a quick transition.

This is one of the main factors that allow RSTP to achieve a faster convergence rate than STP. Another extension of RSTP is the IEEE 802.1s Multiple Spanning Tree Protocol (MSTP), which allows different VLANs to propagate in different spanning tree instances. Unlike STP and RSTP, MSTP eliminates the need to use different STPs for each VLAN.

Therefore, in a large network environment that many VLANs used, MSTP may be more useful than traditional STP.

2.10.1 Bridge Settings

Protocol Version

The MSTP / RSTP / STP protocol version setting. Valid values are STP, RSTP and MSTP.

Bridge Priority

Controls the bridge priority. Lower numeric values have better priority. The bridge priority plus the MSTI instance number, concatenated with the 6-byte MAC address of the switch forms a Bridge Identifier.

For MSTP operation, this is the priority of the CIST. Otherwise, this is the priority of the STP/RSTP bridge.

Hello Time

The interval between sending STP BPDU's. Valid values are in the range 1 to 10 seconds, default is 2 seconds.

Note: Changing this parameter from the default value is not recommended, and may have adverse effects on your network.

Forward Delay

The delay used by STP Bridges to transit Root and Designated Ports to Forwarding (used in STP compatible mode). Valid values are in the range 4 to 30 seconds.

Max Age

The maximum age of the information transmitted by the Bridge when it is the Root Bridge. Valid values are in the range 6 to 40 seconds, and MaxAge must be <= (FwdDelay-1)*2.

Maximum Hop Count

This defines the initial value of remaining Hops for MSTI information generated at the boundary of an MSTI region. It defines how many bridges a root bridge can distribute its BPDU information to. Valid values are in the range 6 to 40 hops.

Transmit Hold Count

The number of BPDU's a bridge port can send per second. When exceeded, transmission of the next BPDU will be delayed. Valid values are in the range 1 to 10 BPDU's per second.

Advanced Settings

Edge Port BPDU Filtering

Control whether a port explicitly configured as Edge will transmit and receive BPDUs.

Control whether a port explicitly configured as Edge will disable itself upon reception of a BPDU. The port will enter the error-disabled state, and will be removed from the active topology.

Port Error Recovery

Control whether a port in the error-disabled state automatically will be enabled after a certain time. If recovery is not enabled, ports have to be disabled and re-enabled for normal STP operation. The condition is also cleared by a system reboot.

Port Error Recovery Timeout

The time to pass before a port in the error-disabled state can be enabled. Valid values are between 30 and 86400 seconds (24 hours).

2.10.2 MSTI Mapping

Configuration Identification

Configuration Name

The name identifying the VLAN to MSTI mapping. Bridges must share the name and revision (see below), as well as the VLAN-to-MSTI mapping configuration in order to share spanning trees for MSTI's (Intra-region). The name is at most 32 characters.

Configuration Revision

The revision of the MSTI configuration named above. This must be an integer between 0 and 65535.

- MSTI Mapping

MSTI

The bridge instance. The CIST is not available for explicit mapping, as it will receive the VLANs not explicitly mapped.

VLANs Mapped

The list of VLANs mapped to the MSTI. The VLANs can be given as a single (xx, xx being between 1 and 4094) VLAN, or a range (xx-yy), each of which must be separated with a comma and/or space. A VLAN can only be mapped to one MSTI. An unused MSTI should just be left empty. (i.e. not having any VLANs mapped to it.) Example: 2,5,20-40.

2.10.3 MSTI Priorities

MSTI Configuration

MSTI

The bridge instance. The CIST is the default instance, which is always active.

STP CIST Port Configuration

Port

The switch port number of the logical STP port.

STP Enabled

Controls whether STP is enabled on this switch port.

Path Cost

Controls the path cost incurred by the port. The Auto setting will set the path cost as appropriate by the physical link speed, using the 802.1D recommended values. Using the Specific setting, a user-defined value can be entered. The path cost is used when establishing the active topology of the network. Lower path cost ports are chosen as forwarding ports in favour of higher path cost ports. Valid values are in the range 1 to 200000000.

Priority

Controls the port priority. This can be used to control priority of ports having identical port cost. (See above).

operEdge (state flag)

Operational flag describing whether the port is connecting directly to edge devices. (No Bridges attached). Transition to the forwarding state is faster for edge ports (having operEdgetrue) than for other ports. The value of this flag is based on AdminEdge and AutoEdge fields. This flag is displayed as Edge in Monitor->Spanning Tree -> STP Detailed Bridge Status.

AdminEdge

Controls whether the operEdge flag should start as set or cleared. (The initial operEdge state when a port is initialized).

AutoEdge

Controls whether the bridge should enable automatic edge detection on the bridge port. This allows operEdge to be derived from whether BPDU's are received on the port or not.

Restricted Role

If enabled, causes the port not to be selected as Root Port for the CIST or any MSTI, even if it has the best spanning tree priority vector. Such a port will be selected as an Alternate Port after the Root Port has been selected. If set, it can cause lack of spanning tree connectivity. It can be set by a network

administrator to prevent bridges external to a core region of the network influence the spanning tree active topology, possibly because those bridges are not under the full control of the administrator. This feature is also known as Root Guard.

Restricted TCN

If enabled, causes the port not to propagate received topology change notifications and topology changes to other ports. If set it can cause temporary loss of connectivity after changes in a spanning tree's active topology as a result of persistently incorrect learned station location information. It is set by a network administrator to prevent bridges external to a core region of the network, causing address flushing in that region, possibly because those bridges are not under the full control of the administrator or the physical link state of the attached LANs transits frequently.

BPDU Guard

If enabled, causes the port to disable itself upon receiving valid BPDU's. Contrary to the similar bridge setting, the port Edge status does not affect this setting.

A port entering error-disabled state due to this setting is subject to the bridge Port Error Recovery setting as well.

Point-to-Point

Controls whether the port connects to a point-to-point LAN rather than to a shared medium. This can be automatically determined, or forced either true or false. Transition to the forwarding state is faster for point-to-point LANs than for shared media.

Port

The switch port number of the corresponding STP CIST (and MSTI) port.

Path Cost

Controls the path cost incurred by the port. The Auto setting will set the path cost as appropriate by the physical link speed, using the 802.1D recommended values. Using the Specific setting, a user-defined value can be entered. The path cost is used when establishing the active topology of the network. Lower path cost ports are chosen as forwarding ports in favor of higher path cost ports. Valid values are in the range 1 to 200000000.

Priority

Controls the port priority. This can be used to control priority of ports having identical port cost. (See above).

2.12 IPMC

The IPMC menu includes the IGMP Snooping and its submenu. Select the appropriate menu to set up the detailed configuration.

2.12.1 IGMP Snooping

Internet Group Management Protocol (IGMP) is a telecommunication protocol that used to manage multicast group members of the Internet Protocol. IGMP is used by IP hosts and neighboring multicast routers to establish multicast group membership.

It can be used more effectively when supporting activities, such as online streaming videos and games. IGMP Snooping is the process of monitoring IGMP traffic. IGMP Snooping, as its name implies, it's a feature that allows "monitoring" in an IGMP session between a host and a router by processing Layer 3 packets of IGMP packets sent over the multicast network.

When IGMP Snooping is enabled in the switch, it analyzes all IGMP packets between the switch connected to the network and the host of the multicast router. When a switch receives an IGMP report from a given multicast group of the host, the switch adds the host's port number to the group's multicast list. When the departure of an IGMP is monitored by the switch, the switch will remove the host's port from the table entry. IGMP Snooping can be more effectively reduce multicast traffic for streaming media and other bandwidth-intensive IP applications. A switch that uses IGMP Snooping will only forward the multicast traffic to the host of this traffic. The switch is generated where it reduces multicast traffic and packet processing (it needs additional memory to handle multicast cost tables), and also reduces the workload of the host network card (or operating system) which does not accept and filter all multicast traffic networks.

2.12.1.1 Basic Configuration

Enable the Global IGMP Snooping.

LLDP

2.13 LLDP

LLDP is a proximity discovery protocol. It defines a standard way for Ethernet network devices, such as switches, routers, and WLAN access points, to advertise their presence to other nodes in the network and to store discovery information for neighboring devices. Details such as device configuration and device identification can be advertised using this protocol. Specifically, LLDP defines a general announcement information set, a protocol for transmitting announcements, and a method for storing received announcement information. A device that advertises its own information may transmit multiple pieces of announcement information in a LAN packet, in the form of a Type Length Value (TLV) field.

LLDP is a one-way protocol. An LLDP agent can send its own system status and its own functions through the associated MSAP, and can also receive the current system status and functions of neighboring devices. However, the LLDP agent cannot request any information from the other party through this protocol. The LLDP proxy does not affect the sending and receiving of information. It can be configured to implement only the sending or receiving functions, or both.

Tx Interval

The switch periodically transmits LLDP frames to its neighbors for having the network discovery information up-to-date. The interval between each LLDP frame is determined by the Tx Interval value. Valid values are restricted to 5 - 32768 seconds.

Tx Hold

Each LLDP frame contains information about how long time the information in the LLDP frame shall be considered valid. The LLDP information valid period is set to Tx Hold multiplied by Tx Interval seconds. Valid values are restricted to 2 - 10 times.

Tx Delay

If some configuration is changed (e.g. the IP address) a new LLDP frame is transmitted, but the time between the LLDP frames will always be at least the value of Tx Delay seconds. Tx Delay cannot be larger than 1/4 of the Tx Interval value. Valid values are restricted to 1 - 8192 seconds.

Tx Reinit

When an interface is disabled, LLDP is disabled or the switch is rebooted, a LLDP shutdown frame is transmitted to the neighboring units, signaling that the LLDP information isn't valid anymore. Tx Reinit controls the number of seconds between the shutdown frame and a new LLDP initialization. Valid values are restricted to 1 - 10 seconds.

Interface

The switch interface name of the logical LLDP interface.

Mode

Select LLDP mode.

• Rx only the switch will not send out LLDP information, but LLDP information from neighbor units is analyzed.
  • Tx only the switch will drop LLDP information received from neighbors, but will send out LLDP information.
  • Disabled The switch will not send out LLDP information, and will drop LLDP information received from neighbors.
• Enabled The switch will send out LLDP information, and will analyze LLDP information received from neighbors.

CDP Aware

Select CDP awareness.

The CDP operation is restricted to decoding incoming CDP frames (The switch doesn't transmit CDP frames). CDP frames are only decoded if LLDP on the interface is enabled.

Only CDP TLVs that can be mapped to a corresponding field in the LLDP neighbors' table are decoded. All other TLVs are discarded (Unrecognized CDP TLVs and discarded CDP frames are not shown in the LLDP statistics.). CDP TLVs are mapped onto LLDP neighbors' table as shown below. CDP TLV "Device ID" is mapped to the LLDP "Chassis ID" field.

CDP TLV "Address" is mapped to the LLDP "Management Address" field. The CDP address TLV can contain multiple addresses, but only the first address is shown in the LLDP neighbors table. CDP TLV "Port ID" is mapped to the LLDP "Port ID" field.

CDP TLV "Version and Platform" is mapped to the LLDP "System Description" field. Both the CDP and LLDP support "system capabilities", but the CDP capabilities cover capabilities that are not part of the LLDP. These capabilities are shown as "others" in the LLDP neighbors' table. If all interfaces have CDP awareness disabled the switch forwards CDP frames received from neighbor devices. If at least one interface has CDP awareness enabled all CDP frames are terminated by the switch.

Note: When CDP awareness on an interface is disabled the CDP information isn't removed immediately, but gets removed when the hold time is exceeded.

Port Descr

Optional TLV: When checked the "port description" is included in LLDP information transmitted.

• Fast Start Repeat count: Quick Start and Emergency Call Service Location Identification Discovering endpoints is a critical aspect of VoIP systems.
In addition, it is best to have only that information that advertises, especially with regard to specific endpoint types (for example, only advertising voice network policies allow devices), in order to save limited LLDPU space and reduce security and system integrity issues. With this in mind, LLDP-MED defines a quick-start interaction between the protocol and the application layer to implement these related attributes.
With Quick Start Repeat Count, you can specify the number of quick starts transfer repetitions. The recommended value is 4 times. When the LLDP framework for new information is received, the 4 LLDP frame will be transmitted and a 1 second interval will be transmitted too.
It is worth noting that the LLDP-MED and LLDP-MED fast-start mechanisms are only suitable for running on links between LLDP-MED network-connected devices and endpoint

devices, and therefore do not apply to links between LAN infrastructure elements, including Network connected devices, or other types of links.

2.14 PoE

Reserved Power determined by: There are three modes for configuring how the ports/PDs may reserve power.

1. Allocated mode: In this mode the user allocates the amount of power that each port may reserve. The allocated/reserved power for each port/PD is specified in the Maximum Power fields.
2. Actual Consumption: In this mode the ports are shut down when the actual power consumption for all ports exceeds the amount of power that the maximum power supply can deliver or if the actual power consumption for a given port exceeds the maximum power for that port. The ports are shut down according to the port's priority. If two ports have the same priority the port with the highest port number is shut down.
3. Reserved Power: Close Port Priority Function Same as Actual Consumption
4. PoE Power Supply Configuration: For being able to determine the amount of power the PD may use, it must be defined what amount of power a power source can deliver. Valid values are in the range 0 to 480 Watts.
5. PoE Port Configuration: Port: This is the logical port number for this row. Ports that are not PoE-capable are grayed out and thus impossible to configure PoE for.
   o PoE Mode: The PoE Mode represents the PoE operating mode for the port.
6. Disabled: PoE disabled for the port.
   o PoE: Enables PoE IEEE 802.3af (Class 3 PDs limited to 15.4W)
   PoE+: Enables PoE+ IEEE 802.3bt(at) (Class 1-6 PSE 30-90W/Class8 PD 71W)

Priority: The Priority represents the port's priority. There are three levels of power priority named Low, High, and Critical. The priority is used in the case where the remote devices require more power than the power supply can deliver. In this case, the port with the lowest priority will be turn off starting from the port with the highest port number.

Maximum Power: The Maximum Power value contains a numerical value that indicates the maximum power in watts that can be delivered to a remote device.

The maximum allowed value is 90 W.

VLAN Translation

2.19 VLAN Translation

VLAN switching is especially useful for users who want to convert the original VLAN ID to a new VLAN ID to exchange data between different VLANs and improve VLAN expansion.

VLAN conversion replaces incoming c-VLAN tags with s-VLAN tags instead of adding extra tags. When configuring VLAN translation, both ends of the link must usually be able to properly replace the tag.

In other words, both endpoints must be configured to properly convert the c-vlan tag to the s-vlan tag and the s-vlan tag to the c-vlan tag in the network.

Note that only the access port supports VLAN translation. It is not recommended to configure VLAN translation on the trunk port. The "VLAN Conversion" menu contains the following submenus. Choose the appropriate configuration settings or view their status.

2.20.1 Membership

Private VLAN Membership Configuration

This page is used to configure a private VLAN. You can add a new private VLAN here, you can modify the existing VLAN. The private VLAN is based on the source port mask and has no connection to the VLAN, which means that the VLAN id and private VLAN id can be the same. The port must be a member of the VLAN and private VLAN to be able to forward packets. By default, all ports are unknown to the VLAN and are members of VLAN 1 and private VLAN 1. A port that the VLAN does not know can only be a member of a VLAN, but it can be a member of multiple private VLANs.

PVLAN ID: Specifies the PVLAN ID, which is called PVID. Valid values are 1 to 8.

Port Members: Select the checkbox, if you want a port to belong to a private VLAN, cancel checkbox and remove a port from a private VLAN.

2.20.2 port Isolation

Port Isolation Configuration

Private VLANs are used to group ports to prevent communication in the PVLAN. Port isolation is used to prevent communication between client ports in the same private VLAN.

A port isolated from others cannot forward any single, multicast, or broadcast traffic to any other port in the same PVLAN. Provide a check box for each port of a private VLAN.

Port isolation is enabled on this port when checking. If not restricted, port isolation is disabled on this port. By default, port isolation is disabled on all ports.

2.21.1

MAC-based VLAN

The MAC-based VLAN configuration page is based on the source MAC address setting VLAN. When a port receives an untagged frame, the source MAC address is processed to determine which VLAN these unmarked frames belong to.

When the source MAC address does not match the created rule, the untagged frame is assigned to the local VLAN ID (PVID) of the receiving port.

MAC-based VLAN Membership Configuration

• MAC address: Indicates the source MAC address. Note that the source MAC address can only be mapped to one VLAN ID.
• VLAN ID: Map this MAC address to the associated VLAN ID.
• Port Members: The port that belongs to this VLAN. For the 8GbE+2 SFP, it shows 10 ports.
- Click "Add New Entry" Create a new rule.
- Click "Save" The changes will be saved and the newly entered rules will be enabled after clicking the "Save" button.
- Click "Reset" Restore the default configuration.

2.21.2

Protocol-based VLAN

• Network devices required to support multiple protocols cannot simply be grouped into a common VLAN. This may require non-standard devices to pass traffic between different vlans to include all devices participating in a particular protocol. This configuration leaves users without the basic benefits of VLANs, including security and accessibility. To avoid these problems, you can configure this switch using a protocol-based VLAN that divides the physical network into logical VLAN groups for each required protocol. When a frame is received on a port, its VLAN members can be determined based on the type of protocol used by the inbound packet.

2.21.2.1 Protocol to Group

Protocol to Group Mapping Table

• Frame Type: There are three types of frameworks to choose from; these are "Ethernet", "SNAP" and "LLC".
- Ethernet: ether type (etype) value. By default, it is set to 0x0800. The allowed range is 0x0600 to 0xffff.
• SNAP: This includes the OUI (Organization's Unique Identifier) and PID (Protocol ID) values.
• LLC: A value in the xx-x-xx format, each pair (xx) in the string is a hexadecimal value in the range 0x00-0xff.
• f the pair is hex 000000, then the protocol ID is the field value of the Ethernet type of the protocol running on top of SNAP.

If it is a specific organization, the protocol ID is the value assigned by the organization, which is the protocol running on top of SNAP.

In other words, if the value of OUI is 000000, then the value of PID will be the ether type (0x0600-0xffff), if the value of OUI is 00-0000,

Then the valid value of the PID will be any value from 0x0000 to 0xffff. (Logical Link Control): This includes DSAP (Target Service Access Point) and SSAP (Source Service Access Point) values. By default, the value is 0xff. The valid range is 0x00 to 0xff.

• Value: This field clearly indicates the type of protocol. This value field varies depending on the type of frame you choose.
• Group Name: Indicates the descriptive name of the entry. This field only allows 16 alphabetic characters (a-z; a - z) or integers (0 - 9).

IP-based VLAN configuration, if the source address is found in the IP subnet to VLAN mapping table, the unlabeled ingress frame is mapped to a specific VLAN. When IP-based VLAN classification is enabled, the source address of the unlabeled ingress framework will be checked on the IP sub-net-to-VLAN mapping table. If an entry is found for the subnet, these frames are assigned to the VLAN specified in the entry.

If there is no matching IP subnet, the untagged frame is divided into VLAN IDs (PVIDs) belonging to the receiving port.

QoS

2.24 QoS

Network traffic is always unpredictable. The only basic guarantee that can be provided is the best traffic delivery. QoS has been applied throughout the network to overcome this challenge. This ensures that network traffic is sorted according to specified criteria and is prioritized. QoS allows you to assign different levels of web services for different types of communication, such as multimedia, video, protocol-specific, time critical, and file backup communications. To set the priority of a packet in this switch, go to the "Port Classification" page.

QoS menu contains the submenus below.

Port

The port number for which the configuration below applies.

CoS

Controls the default class of service. All frames are classified to a CoS. There is a one-to-one mapping between CoS, queue and priority. A CoS of 0 (zero) has the lowest priority.

If the port is VLAN aware, the frame is tagged and Tag Class. is enabled, then the frame is classified to a CoS that is mapped from the PCP and DEI value in the tag. Otherwise, the frame is classified to the default CoS.

The classified CoS can be overruled by a QCL entry.

Note: If the default CoS has been dynamically changed, then the actual default CoS is shown in parentheses after the configured default CoS.

DPL

Controls the default drop precedence level.

All frames are classified to a drop precedence level.

If the port is VLAN aware, the frame is tagged and Tag Class. is enabled, then the frame is classified to a DPL that is mapped from the PCP and DEI value in the tag. Otherwise, the frame is classified to the default DPL.

The classified DPL can be overruled by a QCL entry.

PCP

Controls the default PCP value.

All frames are classified to a PCP value.

If the port is VLAN aware and the frame is tagged, then the frame is classified to the PCP value in the tag. Otherwise, the frame is classified to the default PCP value.

DEI

Controls the default DEI value.

All frames are classified to a DEI value.

If the port is VLAN aware and the frame is tagged, then the frame is classified to the DEI value in the tag. Otherwise, the frame is classified to the default DEI value.

Tag Class.

Shows the classification mode for tagged frames on this port.

- Disabled: Use default CoS and DPL for tagged frames.

- Enabled: Use mapped versions of PCP and DEI for tagged frames.

Click on the mode in order to configure the mode and/or mapping.

Note: This setting has no effect if the port is VLAN unaware. Tagged frames received on VLAN unaware ports are always classified to the default CoS and DPL.

2.24.11 QoS Control List

The QoS Control List is used to establish a policy for processing packets based on frame type, MAC address, Vader, PCP, and DEI values.

Once the QCE is mapped to a port, traffic matching the first entry in the QoS Control List is assigned to the QoS class, drop priority, and the DSCP value defined by the entry.

Traffic that doesn't match any QCEs is divided into the default QoS level of the port.

2.24.12 Storm

Policing

Storm control prevents network degradation or complete shutdown by setting thresholds for traffic such as broadcast, unicast, and multicast.

When a device on the network fails or the application is poorly designed or configured incorrectly, a storm can occur and can degrade network performance and can even lead to complete outages. By setting thresholds for the specified traffic in the device, you can protect your network from storms.

Any specified packet that exceeds the specified threshold will be deleted

Global Storm Policer Configuration

Frame Type	Enable	Rate	Unit
Unicast		1	fps √
Multicast		1	fps √
Broadcast		1	fps √

Enable

Enable or disable the global storm policer for the given frame type.

Rate

Controls the rate for the global storm policer. This value is restricted to 1-1024000 when "Unit" is fps, and 1-1024 when "Unit" is kfps. The rate is internally rounded up to the nearest value supported by the global storm policer.

Unit

Controls the unit of measure for the global storm policer rate as fps or kfps.

Mirroring

2.25 Mirroring

To facilitate management of the switch, you can configure port mirroring and use one port of the switch to observe traffic flowing through a group of ports.

Mirroring&Remote Mirroring Configuration

• Mode: Disabled\Enabled
• Type:

Mirror

The switch is running on mirror mode.

The source port(s) and destination port are located on this switch.

Source

The switch is a source node for monitor flow.

The source port(s), reflector port and intermediate port(s) are located on this switch.

Intermediate

The switch is a forwarding node for monitor flow and the switch is an option node.

The object is to forward traffic from source switch to destination switch.

The intermediate ports are located on this switch.

Destination

The switch is an end node for monitor flow.

The destination port(s) and intermediate port(s) are located on this switch.

VLAN ID: The VLAN ID points out where the monitor packet will copy to. The default VLAN ID is 200.

Reflector Port:

The reflector port is a method to redirect the traffic to Remote Mirroring VLAN. Any device connected to a port set as a reflector port loses connectivity until the Remote Mirroring is disabled.

In the stacking mode, you need to select switch ID to select the correct device.

If you shut down a port, it cannot be a candidate for reflector port.

If you shut down the port which is a reflector port, the remote mirror function cannot work.

Note1: The reflector port needs to select only on Source switch type.

Note2: The reflector port needs to disable MAC Table learning and STP.

Note3: The reflector port only supports on pure copper ports.

Source VLAN(s) Configuration:

The switch can support VLAN-based Mirroring. If you want to monitor some VLANs on the switch, you can set the selected VLANs on this field.

Note: The Mirroring session shall have either ports or VLANs as sources, but not both.

Remote Mirroring Port Configuration:

The following table is used for port role selecting.

Port

The logical port for the settings contained in the same row.

Source

Select mirror mode.

• Disabled Neither frames transmitted nor frames received are mirrored.
• Both Frames received and frames transmitted are mirrored on the Intermediate/Destination port.
- Rx only Frames received on this port are mirrored on the Intermediate/Destination port. Frames transmitted are not mirrored.
• Tx only Frames transmitted on this port are mirrored on the Intermediate/Destination port. Frames received are not mirrored.

Intermediate

Select intermediate port.

This checkbox is designed for Remote Mirroring.

The intermediate port is a switched port to connect to other switch.

Note: The intermediate port needs to disable MAC Table learning.

Destination

Select destination port.

This checkbox is designed for mirror or Remote Mirroring.

The destination port is a switched port that you receive a copy of traffic from the source port.

Note1: On mirror mode, the device only supports one destination port.

Note2: The destination port needs to disable MAC Table learning.

UPnP

2.26 UPnP

2.26.1 UPnP Configuration

UPnP Configuration

Mode

Indicates the UPnP operation mode. Possible modes are:

• Enabled: Enable UPnP mode operation.
• Disabled: Disable UPnP mode operation.

When the mode is enabled, two ACEs are added automatically to trap UPNP related packets to CPU. The ACEs are automatically removed when the mode is disabled.

TTL

The TTL value is used by UPnP to send SSDP advertisement messages. Valid values are in the range 1 to 255.

Advertising Duration

The duration, carried in SSDP packets, is used to inform a control point or control points how often it or they should receive an SSDP advertisement message from this switch. If a control point does not receive any message within the duration, it will think that the switch no longer exists. Due to the unreliable nature of UDP, in the standard it is recommended that such refreshing of advertisements to be done at less than one-half of the advertising duration. In the implementation, the switch sends SSDP messages periodically at the interval one-half of the advertising duration minus 30 seconds. Valid values are in the range 100 to 86400.

GRPRP (GARP VLAN Registration Protocol) is a specific application based on the GARP (Generic Attribute Registration Protocol) protocol.

It uses the working mechanism of the GARP protocol to maintain VLAN information in the switch. All switches that support GVRP can receive VLAN registration information from other switches and update dynamically.

Local VLAN registration information includes the current VLAN membership. And these VLAN members can be reaching by which port. At the same time, all the switches that support the GVRP feature can transmit the local VLAN registration information (including the dynamic VLAN information and the statically configured VLAN information) propagates to other switches to achieve the same VLAN information of all GVRP-enabled devices in the same switching network.

Please enable GVRP globally before enabling GVRP, Otherwise, the GVRP function doesn't work. GVRP can be configured only on the trunk port. Otherwise, the GVRP function will not work too. Port GVRP is closed in the default status.

sFlow is a network monitoring technology co-developed by InMon, HP and FoundryNetworks in 2001. It uses data flow random sampling technology to provide complete Layer 2 to Layer 4, and even network-wide traffic information, which can adapt to traffic analysis in environments with large network traffic (eg, greater than 10 Gbit/s), allowing users to analyze the performance, trends, and problems of network transport flow detailedly in real-time.

2.29 UDLD

UDLD (UniDirectional Link Detection): A Cisco proprietary Layer 2 protocol for monitoring the physical configuration of Ethernet links connected by fiber or twisted pair.

UDLD can detect this situation when a unidirectional link occurs (can only be transmitted in one direction, for example, I can send the data to you, you can also receive it, but I can't receive the data you sent to me.)

Close the corresponding interface and send a warning message. A unidirectional link can cause a lot of problems, especially spanning trees, which can cause loopbacks. Note: UDLD requires both devices at both ends of the link to support normal operation.

Port: Device port number. "*" configuration applies to all ports.

UDLD Mode

Configures the UDLD mode on a port. Valid values are Disable, Normal and Aggressive. Default mode is Disable.

• Disable: In disabled mode, UDLD functionality doesn't exist on port.
• Normal :In normal mode, if the link state of the port was determined to be unidirectional, it will not affect the port state.
• Aggressive: In aggressive mode, unidirectional detected ports will get shutdown. To bring back the ports up, need to disable UDLD on that port.

Message Interval

Configures the period of time between UDLD probe messages on ports that are in the advertisement phase and are determined to be bidirectional. The range is from 7 to 90 seconds (Default value is 7 seconds) (Currently default time interval is supported, due to lack of detailed information in RFC 5171).

3.7.4 Port Security Switch Status

This feature shows the Port Security status. Port Security is a module with no direct configuration. Configuration comes indirectly from other modules - the user modules. When a user module has enabled port security on a port, the port is set-up for software-based learning. In this mode, packets from unknown MAC addresses are passed on to the port security module, which in turn asks all user connected devices whether to allow this new MAC address to forward or block it. For a MAC address to be set in the forwarding state, all enabled user devices must unanimously agree on allowing the MAC address to forward. If only one feature chooses to block it, it will be blocked until that user programmed feature decides otherwise.

The status page is divided into two sections - one with a legend of user modules and one with the actual port status.

NAS is an acronym for Network Access Server. The NAS is meant to act as a gateway to guard access to a protected source. A client connects to the NAS, and the NAS connects to another resource asking whether the client's supplied credentials are valid. Based on the answer, the NAS then allows or disallows access to the protected resource. An example of a NAS implementation is IEEE 802.1X.

Spanning Tree

3.10 Spanning Tree

Spanning tree protocol (STP) is a Layer 2 network protocol used to prevent looping within a network topology. STP was created to avoid the problems that arise when computers compete for the ability to use the shared data path on a local area network (LAN). When too many computers try to send at the same time, overall network performance is affected and can bring all traffic to a near halt.

The Bridge is a snapshot of the current STP state and connections

5.4.7 Appendix 5 Glossary

ACE

ACE is an acronym for Access Control Entry. It describes access permission associated with a particular ACE ID. There are three ACE frame types (Ethernet Type, ARP, and IPv4) and two ACE actions (permit and deny). The ACE also contains many detailed, different parameter options that are available for individual application.

ACL

ACL is an acronym for Access Control List. It is the list table of ACEs, containing access control entries that specify individual users or groups permitted or denied to specific traffic objects, such as a process or a program. Each accessible traffic object contains an identifier to its ACL. The privileges determine whether there are specific traffic object access rights. ACL implementations can be quite complex, for example, when the ACEs are prioritized for the various situation. In networking, the ACL refers to a list of service ports or network services that are available on a host or server, each with a list of hosts or servers permitted or denied to use the service. ACL can generally be configured to control inbound traffic, and in this context, they are similar to firewalls.

AES

AES is an acronym for Advanced Encryption Standard. The encryption key protocol is applied in 802.1i standard to improve WLAN security. It is an encryption standard by the U.S. government, which will replace DES and 3DES. AES has a fixed block size of 128 bits and a key size of 128, 192, or 256 bits.

AMS

AMS is an acronym for Auto Media Select. AMS is used for dual media ports (ports supporting both copper (cu) and fiber (SFP) cables. AMS automatically determines if a SFP or a CU cable is inserted and switches to the corresponding media. If both SFP and cu cables are inserted, the port will select the preferred media.

APS

APS is an acronym for Automatic Protection Switching. This protocol is used to secure that switching is done bidirectional in the two ends of a protection group, as defined in G.8031.

ARP

ARP is an acronym for Address Resolution Protocol. It is a protocol that used to convert an IP address into a physical address, such as an Ethernet address. ARP allows a host to communicate with other hosts when only the Internet address of its neighbors is known. Before using IP, the host sends a broadcast ARP request containing the Internet address of the desired destination system.

ARP Inspection

ARP Inspection is a secure feature. Several types of attacks can be launched against a host or devices connected to Layer 2 networks by "poisoning" the ARP caches. This feature is used to block such attacks. Only valid ARP requests and responses can go through the switch device.

CC

CC is an acronym for Continuity Check. It is a MEP functionality that is able to detect loss of continuity in a network by transmitting CCM frames to a peer MEP.

CCM

CCM is an acronym for Continuity Check Message. It is a OAM frame transmitted from a MEP to its peer MEP and used to implement CC functionality.

CDP

CDP is an acronym for Cisco Discovery Protocol.

DEI

DEI is an acronym for Drop Eligible Indicator. It is a 1-bit field in the VLAN tag.

DES

DES is an acronym for Data Encryption Standard. It provides a complete description of a mathematical algorithm for encrypting (enciphering) and decrypting (deciphering) binary coded information.

DHCP

DHCP is an acronym for Dynamic Host Configuration Protocol. It is a protocol used for assigning dynamic IP addresses to devices on a network.

DHCP Relay

DHCP Relay is used to forward and to transfer DHCP messages between the clients and the server when they are not on the same subnet domain.

DHCP Snooping

DHCP Snooping is used to block intruder on the untrusted ports of the switch device when it tries to intervene by injecting a bogus DHCP reply packet to a legitimate conversation between the DHCP client and server.

DNS

DNS is an acronym for Domain Name System. It stores and associates many types of information with domain names. Most importantly, DNS translates human-friendly domain names and computer hostnames into computer-friendly IP addresses. For example, the domain name www.example.com might translate to 192.168.0.1.

DoS

DoS is an acronym for Denial of Service. In a denial-of-service (DoS) attack, an attacker attempts to prevent legitimate users from accessing information or services. By targeting at network sites or network connection, an attacker may be able to prevent network users from accessing email, web sites, online accounts (banking, etc.), or other services that rely on the affected computer.

DSCP

DSCP is an acronym for Differentiated Services Code Point. It is a field in the header of IP packets for packet classification purposes.

EEE

EEE is an abbreviation for Energy Efficient Ethernet defined in IEEE 802.3az.

EPS

EPS is an abbreviation for Ethernet Protection Switching defined in ITU/T G.8031.

Ethernet Type

Ethernet Type, or EtherType, is a field in the Ethernet MAC header, defined by the Ethernet networking standard. It is used to indicate which protocol is being transported in an Ethernet frame.

FTP

FTP is an acronym for File Transfer Protocol. It is a transfer protocol that uses the Transmission Control Protocol (TCP) and provides file writing and reading. It also provides directory service and security features.

Fast Leave

Multicast snooping Fast Leave processing allows the switch to remove an interface from the forwarding-table entry without first sending out group specific queries to the interface. The VLAN interface is pruned from the multicast tree for the multicast group specified in the original leave message. Fast-leave processing ensures optimal bandwidth management for all hosts on a switched network, even when multiple multicast groups are in use simultaneously. This processing applies to IGMP and MLD.

HTTP

HTTP is an acronym for Hypertext Transfer Protocol. It is a protocol that used to transfer or convey information on the World Wide Web (WWW). HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested

WEB

Web page. The other main standard that controls how the World Wide Web works is HTML, which covers how Web pages are formatted and displayed.

Any Web server machine contains, in addition to the Web page files it can serve, an HTTP daemon, a program that is designed to wait for HTTP requests and handle them when they arrive. The Web browser is an HTTP client, sending requests to server machines. An HTTP client initiates a request by establishing a Transmission Control Protocol (TCP) connection to a particular port on a remote host (port 80 by default). An HTTP server listening on that port waits for the client to send a request message.

HTTPS

HTTPS is an acronym for Hypertext Transfer Protocol over Secure Socket Layer. It is used to indicate a secure HTTP connection. HTTPS provide authentication and encrypted communication and is widely used on the World Wide Web for security-sensitive communication such as payment transactions and corporate logins. HTTPS is really just the use of Netscape's Secure Socket Layer (SSL) as a sublayer under its regular HTTP application layering. (HTTPS uses port 443 instead of HTTP port 80 in its interactions with the lower layer, TCP/IP.) SSL uses a 40-bit key size for the RC4 stream encryption algorithm, which is no longer considered an adequate degree of encryption for commercial exchange.

ICMP

ICMP is an acronym for Internet Control Message Protocol. It is a protocol that generated the error response, diagnostic or routing purposes. ICMP messages generally contain information about routing difficulties or simple exchanges such as time-stamp or echo transactions. For example, the PING command uses ICMP to test an Internet connection.

IEEE 802.1X

IEEE 802.1X is an IEEE standard for port-based Network Access Control. It provides authentication to devices attached to a LAN port, establishing a point-to-point connection or preventing access from that port if authentication fails. With 802.1X, access to all switch ports can be centrally controlled from a server, which means that authorized users can use the same credentials for authentication from any point within the network.

IGMP

IGMP is an acronym for Internet Group Management Protocol. It is a communications protocol used to manage the membership of Internet Protocol multicast groups. IGMP is used by IP hosts and adjacent multicast routers to establish multicast group memberships. It is an integral part of the IP multicast specification, like ICMP for unicast connections. IGMP can be used for online video and gaming, and allows more efficient use of resources when supporting these uses.

IGMP Querier

A router sends IGMP Query messages onto a particular link. This router is called the Querier. There will be only one IGMP Querier that wins Querier election on a particular link.

IMAP

IMAP is an acronym for Internet Message Access Protocol. It is a protocol for email clients to retrieve email messages from a mail server. IMAP is the protocol that IMAP clients use to communicate with the servers, and SMTP is the protocol used to transport mail to an IMAP server. The current version of the Internet Message Access Protocol is IMAP4. It is similar to Post Office Protocol version 3 (POP3), but offers additional and more complex features. For example, the IMAP4 protocol leaves your email messages on the server rather than downloading them to your computer. If you wish to remove your messages from the server, you must use your mail client to generate local folders, copy messages to your local hard drive, and then delete and expunge the messages from the server.

IP

IP is an acronym for Internet Protocol. It is a protocol used for communicating data across an internet network. IP is a "best effort" system, which means that no packet of information sent over is assured to reach its destination in the same condition it was sent. Each device connected to a Local Area Network (LAN) or Wide Area Network (WAN) is given an Internet Protocol address, and this IP address is used to identify the device uniquely among all other devices connected to the extended network. The current version of the Internet protocol is IPv4, which has 32-bits Internet Protocol addresses allowing for in excess of four billion unique addresses. This number is reduced drastically by the practice of webmasters taking addresses in large blocks, the bulk of which remain unused. There is a rather substantial movement to adopt a new

version of the Internet Protocol, IPv6, which would have 128-bits Internet Protocol addresses. This number can be represented roughly by a three with thirty-nine zeroes after it. However, IPv4 is still the protocol of choice for most of the Internet.

IPMC

IPMC is an acronym for IP MultiCast. IPMC supports IPv4 and IPv6 multicasting. IPMCv4 denotes multicast for IPv4. IPMCv6 denotes multicast for IPv6.

IPMC Profile

IPMC Profile is an acronym for IP MultiCast Profile. IPMC Profile is used to deploy the access control on IP multicast streams.

IP Source Guard

IP Source Guard is a secure feature used to restrict IP traffic on DHCP snooping untrusted ports by filtering traffic based on the DHCP Snooping Table or manually configured IP Source Bindings. It helps prevent IP spoofing attacks when a host tries to spoof and use the IP address of another host.

LACP

LACP is an IEEE 802.3ad standard protocol. The Link Aggregation Control Protocol, allows bundling several physical ports together to form a single logical port.

LLC

The IEEE 802.2 Logical Link Control (LLC) protocol provides a link mechanism for upper layer protocols. It is the upper sub-layer of the Data Link Layer and provides multiplexing mechanisms that make it possible for several network protocols (IP, IPX) to coexist within a multipoint network. LLC header consists of 1-byte DSAP (Destination Service Access Point), 1 byte SSAP (Source Service Access Point), 1 or 2 bytes Control field followed by LLC information.

LLDP

LLDP is an IEEE 802.1ab standard protocol. The Link Layer Discovery Protocol (LLDP) specified in this standard allows stations attached to an IEEE 802 LAN to advertise, to other stations attached to the same IEEE 802 LAN, the major capabilities provided by the system incorporating that station, the management address or addresses of the entity or entities that provide management of those capabilities, and the identification of the stations point of attachment to the IEEE 802 LAN required by those management entity or entities. The information distributed via this protocol is stored by its recipients in a standard Management Information Base (MIB), making it possible for the information to be accessed by a Network Management System (NMS) using a management protocol such as the Simple Network Management Protocol (SNMP).

LLDP-MED

LLDP-MED is an extension of IEEE 802.1ab and is defined by the telecommunication industry association (TIA-1057).

LLQI

LLQI (Last Listener Query Interval) is the maximum response time used to calculate the Maximum Response Code inserted into Specific Queries. It is used to detect the departure of the last listener for a multicast address or source. In IGMP, this term is called LMQI (Last Member Query Interval).

LOC

LOC is an acronym for Loss of Connectivity and is detected by a MEP and is indicating lost connectivity in the network. Can be used as switch criteria by EPS

MAC Table

Switching of frames is based upon the DMAC address contained in the frame. The switch builds up a table that maps MAC addresses to switch ports for knowing which ports the frames should go to (based upon the DMAC address in the frame). This table contains both static and dynamic entries. The static entries are configured by the network administrator if the administrator wants to do a fixed mapping between the DMAC address and switch ports.

The frames also contain a MAC address (SMAC address), which shows the MAC address of the equipment sending the frame. The SMAC address is used by the switch to automatically update the MAC table with these dynamic MAC

addresses. Dynamic entries are removed from the MAC table if no frame with the corresponding SMAC address have been seen after a configurable age time.

MEP

MEP is an acronym for Maintenance Entity Endpoint and is an endpoint in a Maintenance Entity Group (ITU-T Y.1731).

MD5

MD5 is an acronym for Message-Digest algorithm 5. MD5 is a message digest algorithm, used cryptographic hash function with a 128-bit hash value. It was designed by Ron Rivest in 1991. MD5 is officially defined in RFC 1321 - The MD5 Message-Digest Algorithm.

Mirroring

For debugging network problems or monitoring network traffic, the switch system can be configured to mirror frames from multiple ports to a mirror port. (In this context, mirroring a frame is the same as copying the frame.)

Both incoming (source) and outgoing (destination) frames can be mirrored to the mirror port.

MLD

MLD is an acronym for Multicast Listener Discovery for IPv6. MLD is used by IPv6 routers to discover multicast listeners on a directly attached link, much as IGMP is used in IPv4. The protocol is embedded in ICMPv6 instead of using a separate protocol.

MLD Querier

A router sends MLD Query messages onto a particular link. This router is called the Querier. There will be only one MLD Querier that wins Querier election on a particular link.

MSTP

In 2002, the IEEE introduced an evolution of RSTP: the Multiple Spanning Tree Protocol. The MSTP protocol provides for multiple spanning tree instances, while ensuring RSTP and STP compatibility. The standard was originally defined by IEEE 802.1s, but was later incorporated in IEEE 802.1D-2005.

MVR

Multicast VLAN Registration (MVR) is a protocol for Layer 2 (IP)-networks that enables multicast-traffic from a source VLAN to be shared with subscriber-VLANs.

The main reason for using MVR is to save bandwidth by preventing duplicate multicast streams being sent in the core network, instead the stream(s) are received on the MVR-VLAN and forwarded to the VLANs where hosts have requested it/them (Wikipedia).

NAS

NAS is an acronym for Network Access Server. The NAS is meant to act as a gateway to guard access to a protected source. A client connects to the NAS, and the NAS connects to another resource asking whether the client's supplied credentials are valid. Based on the answer, the NAS then allows or disallows access to the protected resource. An example of a NAS implementation is IEEE 802.1X.

NetBIOS

NetBIOS is an acronym for Network Basic Input/Output System. It is a program that allows applications on separate computers to communicate within a Local Area Network (LAN), and it is not supported on a Wide Area Network (WAN).

The NetBIOS giving each computer in the network both a NetBIOS name and an IP address corresponding to a different host name, provides the session and transport services described in the Open Systems Interconnection (OSI) model.

NFS

NFS is an acronym for Network File System. It allows hosts to mount partitions on a remote system and use them as though they are local file systems.

NFS allows the system administrator to store resources in a central location on the network, providing authorized users continuous access to them, which means NFS supports sharing of files, printers, and other resources as persistent storage over a computer network.

NTP

NTP is an acronym for Network Time Protocol, a network protocol for synchronizing the clocks of computer systems. NTP uses UDP (datagrams) as transport layer.

OAM

OAM is an acronym for Operation Administration and Maintenance.

It is a protocol described in ITU-T Y.1731 used to implement carrier Ethernet functionality. MEP functionality like CC and RDI is based on this.

Optional TLVs.

A LLDP frame contains multiple TLVs. For some TLVs it is configurable if the switch shall include the TLV in the LLDP frame. These TLVs are known as optional TLVs. If an optional TLVs is disabled the corresponding information is not included in the LLDP frame.

OUI

OUI is the organizationally unique identifier. An OUI address is a globally unique identifier assigned to a vendor by IEEE. You can determine which vendor a device belongs to according to the OUI address which forms the first 24 bits of a MAC address.

PCP

PCP is an acronym for Priority Code Point. It is a 3-bit field storing the priority level for the 802.1Q frame. It is also known as User Priority.

PD

PD is an acronym for Powered Device. In a PoE system the power is delivered from a PSE (power sourcing equipment) to a remote device. The remote device is called a PD.

PHY

PHY is an abbreviation for Physical Interface Transceiver and is the device that implements the Ethernet physical layer (IEEE-802.3).

PING

Ping (Packet InterNet Grouper) is a program that sends a series of packets over a network or the Internet to a specific computer in order to generate a response from that computer. The other computer responds with an acknowledgment that it received the packets. Ping was created to verify whether a specific computer on a network or the Internet exists and is connected. Ping uses Internet Control Message Protocol (ICMP) packets. The PING Request is the packet from the origin computer, and the PING Reply is the packet response from the target.

PoE

PoE is an acronym for Power Over Ethernet. Power over Ethernet is used to transmit electrical power, to remote devices over standard Ethernet cable. It could for example be used for powering IP telephones, wireless LAN Access Points (AP), IP cameras and other equipment, where it would be difficult or expensive to connect the equipment to main power supply.

Policer

A policer can limit the bandwidth of received frames. It is located in front of the ingress queue.

POP3

POP3 is an acronym for Post Office Protocol version 3. It is a protocol for email clients to retrieve email messages from a mail server.

POP3 is designed to delete mail on the server as soon as the user has downloaded it. However, some implementations allow users or an administrator to specify that mail be saved for some period of time. POP can be thought of as a "store-and-forward" service.

An alternative protocol is Internet Message Access Protocol (IMAP). IMAP provides the user with more capabilities for retaining e-mail on the server and for organizing it in folders on the server. IMAP can be thought of as a remote file server.

POP and IMAP deal with the receiving of e-mail and are not to be confused with the Simple Mail Transfer Protocol (SMTP). You send e-mail with SMTP, and a mail handler receives it on your recipient's behalf. Then the mail is read using POP or IMAP. IMAP4 and POP3 are the two most prevalent Internet standard protocols for e-mail retrieval. Virtually all modern e-mail clients and servers support both.

PPPoE

PPPoE is an acronym for Point-to-Point Protocol over Ethernet. It is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It is used mainly with ADSL services where individual users connect to the ADSL transceiver (modem) over Ethernet and in plain Metro Ethernet networks (Wikipedia).

QoS

QoS is an acronym for Quality of Service. It is a method to guarantee a bandwidth relationship between individual applications or protocols.

A communications network transports a multitude of applications and data, including high-quality video and delay-sensitive data such as real-time voice. Networks must provide secure, predictable, measurable, and sometimes guaranteed services.

Achieving the required QoS becomes the secret to a successful end-to-end business solution. Therefore, QoS is the set of techniques to manage network resources.

QoS class

Every incoming frame is classified to a QoS class, which is used throughout the device for providing queuing, scheduling and congestion control guarantees to the frame according to what was configured for that specific QoS class. There is a one-to-one mapping between QoS class, queue and priority. A QoS class of 0 (zero) has the lowest priority.

Standard IEEE 802.1D-2004 now incorporates RSTP and obsoletes STP, while at the same time being backwards-compatible with STP.

SAMBA

Samba is a program running under UNIX-like operating systems (not the Brazilian dance) that provides seamless integration between UNIX and Microsoft Windows machines. Samba acts as file and print servers for Microsoft Windows, IBM OS/2, and other SMB client machines. Samba uses the Server Message Block (SMB) protocol and Common Internet File System (CIFS), which is the underlying protocol used in Microsoft Windows networking.

Samba can be installed on a variety of operating system platforms, including Linux, most common Unix platforms, OpenVMS, and IBM OS/2.

Samba can also register itself with the master browser on the network so that it would appear in the listing of hosts in Microsoft Windows "Neighborhood Network".

sFlow

sFlow is an industry standard technology for monitoring switched networks through random sampling of packets on switch ports and time-based sampling of port counters. The sampled packets and counters (referred to as flow samples and counter samples, respectively) are sent as sFlow UDP datagrams to a central network traffic monitoring server. This central server is called an sFlow receiver or sFlow collector.

Additional information can be found at http://sflow.org.

SHA

SHA is an acronym for Secure Hash Algorithm. It designed by the National Security Agency (NSA) and published by the NIST as a U.S. Federal Information Processing Standard. Hash algorithms compute a fixed-length digital representation (known as a message digest) of an input data sequence (the message) of any length.

Shaper

A shaper can limit the bandwidth of transmitted frames. It is located after the ingress queues.

Stack Protocol using ROUting Technology. An advanced protocol for almost instantaneous discovery of topology changes within a stack as well as election of a master switch. SPROUT also calculates parameters for setting up each switch to perform shortest path forwarding within the stack.

SSID

Service Set Identifier is a name used to identify the particular 802.11 wireless LANs to which a user wants to attach. A client device will receive broadcast messages from all access points within range advertising their SSIDs, and can choose one to connect to based on pre-configuration, or by displaying a list of SSIDs in range and asking the user to select one (wikipedia).

SSH

SSH is an acronym for Secure SHell. It is a network protocol that allows data to be exchanged using a secure channel between two networked devices. The encryption used by SSH provides confidentiality and integrity of data over an insecure network. The goal of SSH was to replace the earlier rlogin, TELNET and rsh protocols, which did not provide strong authentication or guarantee confidentiality (Wikipedia).

Tag Priority

Tag Priority is a 3-bit field storing the priority level for the 802.1Q frame. The 3-bits provide 8 priority levels (0\~7).

TCP

TCP is an acronym for Transmission Control Protocol. It is a communications protocol that uses the Internet Protocol (IP) to exchange the messages between computers.

The TCP protocol guarantees reliable and in-order delivery of data from sender to receiver and distinguishes data for multiple connections by concurrent applications (for example, Web server and e-mail server) running on the same host.

The applications on networked hosts can use TCP to create connections to one another. It is known as a connection-oriented protocol, which means that a connection is established and maintained until such time as the message or messages to be exchanged by the application programs at each end have been exchanged. TCP is responsible for ensuring that a message is divided into the packets that IP manages and for reassembling the packets back into the complete message at the other end. Common network applications that use TCP include the World Wide Web (WWW), e-mail, and File Transfer Protocol (FTP).

TELNET

TELNET is an acronym for TELetype NETwork. It is a terminal emulation protocol that uses the Transmission Control Protocol (TCP) and provides a virtual connection between TELNET server and TELNET client.

TELNET enables the client to control the server and communicate with other servers on the network. To start a Telnet session, the client user must log in to a server by entering a valid username and password. Then, the client user can enter commands through the Telnet program just as if they were entering commands directly on the server console.

TFTP

TFTP is an acronym for Trivial File Transfer Protocol. It is transfer protocol that uses the User Datagram Protocol (UDP) and provides file writing and reading, but it does not provide directory service and security features.

ToS

ToS is an acronym for Type of Service. It is implemented as the IPv4 ToS priority control. It is fully decoded to determine the priority from the 6-bit ToS field in the IP header. The most significant 6 bits of the ToS field are fully decoded into 64 possibilities, and the singular code that results is compared against the corresponding bit in the IPv4 ToS priority control bit (0\~63).

TLV

TLV is an acronym for Type Length Value. A LLDP frame can contain multiple pieces of information. Each of these pieces of information is known as TLV.

TKIP

TKIP is an acronym for Temporal Key Integrity Protocol. It used in WPA to replace WEP with a new encryption algorithm. TKIP comprises the same encryption engine and RC4 algorithm defined for WEP. The key used for encryption in TKIP is 128 bits and changes the key used for each packet.

UDP

UDP is an acronym for User Datagram Protocol. It is a communications protocol that uses the Internet Protocol (IP) to exchange the messages between computers.

UDP is an alternative to the Transmission Control Protocol (TCP) that uses the Internet Protocol (IP). Unlike TCP, UDP does not provide the service of dividing a message into packet datagrams, and UDP doesn't provide reassembling and sequencing of the packets. This means that the application program that uses UDP must be able to make sure that the entire message has arrived and is in the right order. Network applications that want to save processing time because they have very small data units to exchange may prefer UDP to TCP.

UDP provides two services not provided by the IP layer. It provides port numbers to help distinguish different user requests and, optionally, a checksum capability to verify that the data arrived intact.

Common network applications that use UDP include the Domain Name System (DNS), streaming media applications such as IPTV, Voice over IP (VoIP), and Trivial File Transfer Protocol (TFTP).

UPnP

UPnP is an acronym for Universal Plug and Play. The goals of UPnP are to allow devices to connect seamlessly and to simplify the implementation of networks in the home (data sharing, communications, and entertainment) and in corporate environments for simplified installation of computer components.

User Priority is a 3-bit field storing the priority level for the 802.1Q frame. It is also known as PCP.

VLAN

Virtual LAN.A method to restrict communication between switch ports. VLANs can be used for the following applications:

VLAN unaware switching: This is the default configuration. All ports are VLAN unaware with Port VLAN ID 1 and members of VLAN 1. This means that MAC addresses are learned in VLAN 1, and the switch does not remove or insert VLAN tags.

VLAN aware switching: This is based on the IEEE 802.1Q standard. All ports are VLAN aware. Ports connected to VLAN aware switches are members of multiple VLANs and transmit tagged frames. Other ports are members of one VLAN, set up with this Port VLAN ID, and transmit untagged frames. Provider switching: This is also known as Q-in-Q switching. Ports connected to subscribers are VLAN unaware, members of one VLAN, and set up with this unique Port VLAN ID. Ports connected to the service provider are VLAN aware, members of multiple VLANs, and set up to tag all frames. Untagged frames received on a subscriber port are forwarded to the provider port with a single VLAN tag. Tagged frames received on a subscriber port are forwarded to the provider port with a double VLAN tag.

VLAN ID

VLAN ID is a 12-bit field specifying the VLAN to which the frame belongs.

Voice VLAN

Voice VLAN is VLAN configured specially for voice traffic. By adding the ports with voice devices attached to voice VLAN, we can perform QoS-related configuration for voice data, ensuring the transmission priority of voice traffic and voice quality.

WEP

WEP is an acronym for Wired Equivalent Privacy. WEP is a deprecated algorithm to secure IEEE 802.11 wireless networks. Wireless networks broadcast messages using radio, and are more susceptible to eavesdropping than wired networks. When introduced in 1999, WEP was intended to provide confidentiality comparable to that of a traditional wired network (Wikipedia).

WiFi

WiFi is an acronym for Wireless Fidelity. It is meant to be used generically when referring of any type of 802.11 network, whether 802.11b, 802.11a, dual-band, etc. The term is promulgated by the Wi-Fi Alliance.

WPA

WPA is an acronym for Wi-Fi Protected Access. It was created in response to several serious weaknesses researchers had found in the previous system, Wired Equivalent Privacy (WEP). WPA implements the majority of the IEEE 802.11i standard, and was intended as an intermediate measure to take the place of WEP while 802.11i was prepared. WPA is specifically designed to also work with pre-WPA wireless network interface cards (through firmware upgrades), but not necessarily with first generation wireless access points. WPA2 implements the full standard, but will not work with some older network cards (Wikipedia).

WPA-PSK

WPA-PSK is an acronym for Wi-Fi Protected Access - Pre-Shared Key. WPA was designed to enhance the security of wireless networks. There are two flavors of WPA: enterprise and personal. Enterprise is meant for use with an IEEE 802.1X authentication server, which distributes different keys to each user. Personal WPA utilizes less scalable 'pre-shared key' (PSK) mode, where every allowed computer is given the same passphrase. In PSK mode, security depends on the strength and secrecy of the passphrase. The design of WPA is based on a Draft 3 of the IEEE 802.11i standard (Wikipedia)

WPA-Radius

WPA-Radius is an acronym for Wi-Fi Protected Access - Radius (802.1X authentication server). WPA was designed to enhance the security of wireless networks. There are two flavors of WPA: enterprise and personal. Enterprise is meant for use with an IEEE 802.1X authentication server, which distributes different keys to each user. Personal WPA utilizes less scalable 'pre-shared key' (PSK) mode, where every allowed computer is given the same passphrase. In PSK mode

security depends on the strength and secrecy of the passphrase. The design of WPA is based on a Draft 3 of the IEEE 802.11i standard (Wikipedia).

WPS

WPS is an acronym for Wi-Fi Protected Setup. It is a standard for easy and secure establishment of a wireless home network. The goal of the WPS protocol is to simplify the process of connecting any home device to the wireless network (Wikipedia).

WRED

WRED is an acronym for Weighted Random Early Detection. It is an active queue management mechanism that provides preferential treatment of higher priority frames when traffic builds up within a queue. A frame's DP level is used as input to WRED. A higher DP level assigned to a frame results in a higher probability that the frame is dropped during times of congestion.

WTR

WTR is an acronym for Wait To Restore. This is the time a fail on a resource has to be 'not active' before restoration back to this (previously failing) resource is done.
