Features and Applications

Part I Features And Applications

This part acquaints you with the features and applications of the ES-3024.

Dimension ES-3024 Ethernet Switch

Chapter 1 Getting to Know the ES-3024

This chapter describes the key features, benefits and applications of the ES-3024.

The ES-3024 is a stand-alone Ethernet switch with 24 10/100Mbps ports, two slots for electrical or optical uplink modules and one slot for a stacking module.

With its built-in web configurator, managing and configuring the switch is easy. From cabinet management to port- level control and monitoring, you can visually configure and manage your network via the web browser. Just click your mouse instead of typing cryptic command strings. In addition, the switch can also be managed via Telnet, the console port, or third-party SNMP management.

The next two sections describe the hardware and firmware features of the ES-3024.

1.1.1 Hardware Features

The ES-3024 DC model requires DC power supply input of -48 VDC to -60 VDC, 1.84A Max. The ES-3024 AC model requires 100-240VAC/1.5A power.

24 10/100 Mbps Fast Ethernet Ports

Connect up to 24 computers or switches to the 10/100Mbps auto-negotiating, automatic cable sensing (auto-MDIX) Ethernet RJ-45 ports. All Ethernet ports support:

> IEEE 802.3/3u/3z/3ab standards > Back pressure flow control in half duplex mode > IEEE 802.3x flow control in full duplex mode Two Slots for Uplink Modules The modules allow the ES-3024 to connect to another WAN switch or daisy-chain to other switches. One Slot for Stacking Module Up to eight switches may be stacked using stacking modules. Console Port Use the console port for local management of the switch.

The fans cool the ES-3024 sufficiently to allow reliable operation of the switch in even poorly ventilated rooms or basements.

Port Link Aggregation

The ES-3024 adheres to the 802.3ad standard for static and dynamic port link aggregation.

1-2 Getting to Know the ES-3024

Dimension ES-3024 Ethernet Switch

> The ES-3024 supports rate limiting in 1Kbps increments allowing you to create different service plans

> The ES-3024 supports IGMP snooping enabling group multicast traffic to be only forwarded to ports that are members of that group; thus allowing you to significantly reduce multicast traffic passing through your switch.

> Broadcast storm control

> Four priority queues so you can ensure mission-critical data gets delivered on time.

> Follows the IEEE 802.1p priority setting standard based on source/destination MAC addresses. STP (Spanning Tree Protocol) / RSTP (Rapid STP)

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

Cluster Management allows you to manage switches through one switch, called the cluster manager. The switches must be directly connected and be in the same VLAN group so as to be able to communicate with one another.

This section shows a few examples of using the ES-3024 in various network environments.

1.2.1 Backbone Application In this application, the switch is an ideal solution for small networks where rapid growth can be expected in the near future.

The switch can be used standalone for a group of heavy traffic users. You can connect computers directly to the switch’s port or connect other switches to the ES-3024.

In this example, all computers connected directly or indirectly to the ES-3024 can share super high-speed applications on the Gigabit server.

To expand the network, simply add more networking devices such as switches, routers, firewalls, print servers etc.

Getting to Know the ES-3024 1-3

Dimension ES-3024 Ethernet Switch

1.2.2 Bridging Example

In this example application the switch is the ideal solution for different company departments to connect to the corporate backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All users that need high bandwidth can connect to high-speed department servers via the switch. You can provide a super- fast uplink connection by selecting from an array of uplink modules compatible with the ES-3024.

Moreover, the switch eases supervision and maintenance by allowing network managers to centralize multiple servers at a single location.

1-4 Getting to Know the ES-3024

Dimension ES-3024 Ethernet Switch

Figure 1-2 Bridging Application

Full-duplex mode operation only applies to point-to-point access (for example, when attaching the switch to a workstation, server, or another switch). When connecting to hubs, use a standard cascaded connection set at half-duplex operation.

1.2.3 High Performance Switched Workgroup Example

The switch is ideal for connecting two power workgroups that need high bandwidth. In the following example, use trunking to connect these two power workgroups.

Switching to higher-speed LANS such as FDDI or ATM is not feasible for most people due to the expense of replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance.

The ES-3024 can provide the same bandwidth as FDDI and ATM at much lower cost while still being able to use existing adapters and switches. Moreover, the current LAN structure can be retained as all ports can freely communicate with each other.

Getting to Know the ES-3024 1-5

Dimension ES-3024 Ethernet Switch

Figure 1-3 High Performance Switched Workgroup Application

1.2.4 IEEE 802.1Q VLAN Application Examples

This section shows a workgroup and a shared server example using 802.1Q tagged VLANSs. For more information on VLANS, see the Switch Setup and VLAN Setup chapters in this User’s Guide. A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical network belong to one group. A station can belong to more than one group. With VLAN, a station cannot directly talk to or hear from stations that are not in the same group(s) unless such traffic first goes through a router.

Tag-based VLAN Workgroup Example

Ports in the same VLAN group share the same broadcast domain thus increase network performance through reduced broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without any re-cabling.

1-6 Getting to Know the ES-3024

Dimension ES-3024 Ethernet Switch

VLAN Shared Server Example

Shared resources such as a server can be used by all ports in the same VLAN as the server, as shown in the following example. In this example, only ports that need access to the server need belong to VLAN 3 while they

can belong to other VLAN groups too.

Hardware Installation & Connections

Part II Hardware Installation & Connections

| This part acquaints you with installation scenarios of the ES-3024, instructs you on how to make | the hardware connections including installing/removing modules, shows some stacking/uplink examples and explains the front panel LEDs.

Dimension ES-3024 Ethernet Switch

Chapter 2 Hardware Installation

This chapter shows two switch installation scenarios.

2.1 Installation Scenarios

The switch can be placed on a desktop or rack-mounted on a standard EIA rack. Use the rubber feet in a desktop installation and the brackets in a rack-mounted installation.

For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4 inches (8 cm) at the back of the switch. This is especially important for enclosed rack installations.

2.1.1 Desktop Installation Procedure

Step 1. Make sure the switch is clean and dry.

Step 2. Set the switch on a smooth, level surface strong enough to support the weight of the switch and the connected cables. Make sure there is a power outlet nearby.

Step 3. Make sure there is enough clearance around the switch to allow air circulation and the attachment of cables and the power cord.

Step 4. Remove the adhesive backing from the rubber feet.

Step 5. Attach the rubber feet to each corner on the bottom of the switch. These rubber feet help protect the switch from shock or vibration and ensure space between switches when stacking.

Figure 2-1 Attaching Rubber Feet

Do not block the ventilation holes. Leave space between switches when stacking.

Hardware Installation 2-1

Dimension ES-3024 Ethernet Switch

2.1.2 Rack-Mounted Installation The switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other equipment. Follow the steps below to mount your switch on a standard EIA rack using a rack-mounting kit.

Step 1. Align one bracket with the holes on one side of the switch and secure it with the bracket screws smaller than the rack-mounting screws.

Step 2. Attach the other bracket in a similar fashion.

Figure 2-2 Attaching Mounting Brackets and Screws

Step 3. After attaching both mounting brackets, position the switch in the rack by lining up the holes in the brackets with the appropriate holes on the rack. Secure the switch to the rack with the rack-mounting

> The length of exposed (bare) power wire should not exceed 7mm.

> Do not use this product near water, for example, in a wet basement.

> Only a qualified technician should service or disassemble this device.

The following figure shows the front panel of the ES-3024. The front panel contains a console port for local switch management, switch LEDs, 24 RJ-45 Ethernet ports and two (optional) uplink modules.

Console Port Ethernet Parts Uplink Modules (optional)

CONNECTOR DESCRIPTION Console The console port is for local configuration of the ES-3024 switch.

24 10/100 Mbps RJ-45 | Connect these ports to a computer, a hub, an Ethernet switch or router. Ethernet connectors

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

Dimension ES-3024 Ethernet Switch

Connect the male 9-pin end of the console cable to the console port of the ES-3024 switch. Connect the female end to a serial port (COMI, COM2 or other COM port) of your computer.

3.2.2 Ethernet Ports

The ES-3024 has 10/100Mbps auto-negotiating, auto-crossover Ethernet ports. In 10/100Mbps Fast Ethernet, the speed can be 10Mbps or 100Mbps and the duplex mode can be half duplex or full duplex (100 Mbps only).

When auto-negotiation is turned on, an Ethernet port on the ES-3024 switch negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer Ethernet port does not support auto-negotiation or turns off this feature, the ES-3024 switch determines the connection speed by detecting the signal on the cable and using half duplex mode. When the ES-3024 switch’s auto-negotiation is turned off, an Ethernet port uses the pre- configured speed and duplex mode when making a connection, thus requiring you to make sure that the settings of the peer Ethernet port are the same in order to connect.

Default Ethernet Negotiation Settings

The factory default negotiation settings for the Ethernet ports on the ES-3024 switch are:

o Speed: Auto o Duplex: Auto o Flow control: On o Link Aggregation: Disabled

All ports are auto-crossover, that is auto-MDIX ports (Media Dependent Interface Crossover), so you may use either a straight through Ethernet cable or crossover Ethernet cable for all Ethernet port connections. Auto- crossover ports automatically sense whether they need to function as crossover or straight ports, so crossover cables can connect both computers and switches/hubs.

LEDs in the (optional) uplink modules are described in the corresponding module manual.

3.3.1 Installing Modules

You can install one stacking module and up to two (optional) uplink modules separately to meet the needs of your network. See your module manual for module specifications.

Modules are NOT hot swappable!

Follow these steps to install the optional modules.

Step 1. Make sure the power cord is not connected to the switch.

Loosen the thumbscrews from the cover plate and remove the cover plate from the optional slot. Do not discard the cover plate. You can put the cover plate back on if you remove the new module.

Figure 3-2 Loosening the Screws and Removing the Cover Plate

You should wear an anti-static wrist strap or touch any grounded or metal objects to discharge any bodily static electricity before you continue.

Remove the optional module from its protective anti-static packaging. Avoid touching the onboard circuit components by holding it by the edge.

Insert the optional module into an available expansion slot on the switch. Press it firmly until the optional module snaps into place.

Secure it to the switch with the retaining screws.

Slide the optional module into the expansion slot until

it snaps into place.

Never force, bend or twist the optional modules into the expansion slots.

Hardware Connections 3-3

Step7. See section 3.4.1 for instructions on connecting the power. The switch automatically detects the installed optional module. Connect any necessary network cables to the optional module and check the LEDs to verify that it is functioning properly.

The following figure shows the rear panel of the ES-3024. The rear panel contains the slot for the stacking module and the power receptacle. See section 3.3.1 for information on inserting and removing modules.

100-240VAC 50/40Ha 1.SAMAX FUSE T2ZA250VAC DC POWER INPUT Figure 3-5 ES-3024 DC Unit Rear Panel

3.4.1 Power Connector

Make sure you are using the correct power source as shown on the panel.

To connect the power to the ES-3024 AC unit, insert the female end of power cord to the power receptacle on the rear panel. Connect the other end of the supplied power cord to a 100-240VAC/1.5A power outlet. Make sure that no objects obstruct the airflow of the fans (located on the side of the unit).

The ES-3024 DC unit requires DC power supply input of 48 VDC to -60 VDC, 1.84A Max. To connect the power to the unit, insert the one end of the supplied power cord to the power receptacle on the rear panel and the other end to a power outlet.

3.5 Front Panel LEDs

After you connect the power to the switch, view the LEDs to ensure proper functioning of the switch and as an aid in troubleshooting. The front panel LEDs are as follows.

Q STACKING Figure 3-10 Uplink Example

3.8 Configuring the ES-3024

You may use the embedded web configurator or command line interface to configure the ES-3024. If you're using the web configurator, you need Internet Explorer 5.5 and later or Netscape Navigator 6 and later.

You can access the command line interface using a terminal emulation program on a computer connected to the switch console port (see section 3.2.1) or access the switch via an Ethernet port using Telnet.

You can use the “config save” command to save 802.1Q, STP, Cluster and IP configuration changes to non-volatile memory (Flash). These changes are effective after you restart the switch.

However you cannot use “config save” for all other line command configurations. These are saved in volatile memory (DRAM), so are not effective after you restart the switch.

The next part of this guide discusses configuring the ES-3024 using the web configurator.

Please record your new password whenever you change it. The system will lock you out if you have forgotten your password.

User Name Password Retype to confirm

You are locked out from managing the switch if another administrator is currently logged in. You must wait until

he/she has logged out before you can log in. Moreover, you could lock yourself (and all others) out from the switch by:

1. Deleting the management VLAN (default is VLAN 1).

2. Deleting all port-based VLANS with the CPU port as a member. The “CPU port” is the management port of

Dimension ES-3024 Ethernet Switch

3. Filtering all traffic to the CPU port. 4. Disabling all ports.

5. Assigning minimum bandwidth to the CPU port. If you limit bandwidth to the CPU port, you may find that the switch performs sluggishly or not at all.

Be careful not to lock yourself and others out of the switch.

4.5 Resetting the Switch

If you lock yourself (and others) from the switch or forget the ES-3024 password, you will need to reload the factory-default configuration file.

Uploading the factory-default configuration file replaces the current configuration file with the factory-default configuration file. This means that you will lose all previous configurations and the speed of the console port will be reset to the default of 9600bps with 8 data bit, no parity, one stop bit and flow control set to none. The password will also be reset to “1234” and the IP address to 192.168.1.1.

To upload the configuration file, do the following:

Step 1. Connect to the console port using a computer with terminal emulation software. See the chapter on hardware connections for details.

Step 2. Disconnect and reconnect the switch’s power to begin a session. When you reconnect the switch’s power, you will see the initial screen.

Step 3. When you see the message “Press any key to enter Debug Mode within 3 seconds” press any key to enter debug mode.

Step 4. Type atlc after the “Enter Debug Mode” message.

Step 5. Wait for the “Starting XMODEM upload” message before activating XMODEM upload on your terminal.

Step 6. After a successful configuration file upload, type at go to restart the switch.

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

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

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

Note that VLAN is unidirectional; it only governs outgoing traffic.

Dimension ES-3024 Ethernet Switch

See the VLAN chapter for information on port-based and 802.1Q tagged VLANSs.

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

A layer-2 switch can passively snoop on IGMP Query, Report and Leave (IGMP version 2) packets transferred between IP multicast routers/switches and IP multicast hosts to learn the IP multicast group membership. It checks IGMP packets passing through it, picks out the group registration information, and configures multicasting accordingly.

Without IGMP snooping, multicast traffic is treated in the same manner as broadcast traffic, that is, it is forwarded to all ports. With IGMP snooping, group multicast traffic is only forwarded to ports that are members of that group. IGMP Snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through your switch.

6.6 Switch Setup Screen

Click Basic Setting and then Switch Setup in the navigation panel display the screen as shown. The VLAN setup screens change depending on whether you choose 802.1Q or Port Based in the VLAN Type field in this screen. Refer to the chapter on VLANSs.

Table 6-3 Switch Setup

LABEL DESCRIPTION EXAMPLE GARP Timer: Switches join VLANSs by making a declaration. À declaration is made by issuing a Join message using GARP. Declarations are withdrawn by issuing a Leave message. À Leave All message terminates all registrations. GARP timers set declaration timeout values. See the chapter on VLAN setup for more background information.

Join Timer|Join Timer sets the duration of the Join Period timer for GVRP in milliseconds. 200 milliseconds Each port has a Join Period timer. The allowed Join Time range is between 100 (default) and 65535 milliseconds; the default is 200 milliseconds. See the chapter on VLAN setup for more background information.

Leave Timer|Leave Timer sets the duration of the Leave Period timer for GVRP in 600 milliseconds milliseconds. Each port has a single Leave Period timer. Leave Time must be two (default) times larger than Join Timer; the default is 600 milliseconds.

Leave All' Leave All Timer sets the duration of the Leave All Period timer for GVRP in 1000 Timer|milliseconds. Each port has a single Leave All Period timer. Leave All Timer must milliseconds be larger than Leave Timer; the default is 1000 milliseconds. (default)

Priority Queue Assignment

IÉEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer frame that contains bits to define class of service. Frames without an explicit priority tag are given the default priority of the ingress port. Use the next two fields to configure the priority level-to-physical queue mapping.

The switch has 4 physical queues that you can map to the 8 priority levels. On the switch, traffic assigned to higher index queues gets through faster while traffic in lower index queues is dropped if the network is congested.

See also Queuing Method and 802.1p Priority in Port Setup for related information.

Priority Level (The following descriptions are based on the traffic types defined in the IEEE 802.1d standard (which incorporates the 802.1p).

Level 7|Typically used for network control traffic such as router configuration messages.

Level 6|Typically used for voice traffic that is especially sensitive to jitter (jitter is the variations in delay).

Level 5|Typically used for video that consumes high bandwidth and is sensitive to jitter.

Typically used for controlled load, latency-sensitive traffic such as SNA (Systems Network

Level4 Architecture) transactions.

Typically used for “excellent effort” or better than best effort and would include important business

Level 3 traffic that can tolerate some delay.

Level 2|This is for “spare bandwidth”.

This is typically used for non-critical “background” traffic such as bulk transfers that are allowed but

Level 1 that should not affect other applications and users.

Level 0|Typically used for best-effort traffic.

The following table describes the fields in this screen.

This is the port index number.

Select this check box to enable a port. The factory default for all ports is enabled. A port must be enabled for data transmission to occur.

Enter a descriptive name that identifies this port.

This field displays 10/100M for an Ethernet/Fast Ethernet connection and 1000M for Gigabit connections.

Select the speed and the duplex mode of the Ethernet connection on this port. Choices are Auto, 10M/Half Duplex, 10M/Full Duplex, 100M/Half Duplex, 100M/Full Duplex and 1000M/Full Duplex (for gigabit ports only).

Selecting Auto (auto-negotiation) makes one Ethernet port able to negotiate with a peer automatically to obtain the connection speed and duplex mode that both ends support. When auto- negotiation is turned on, an Ethernet port on the switch negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer Ethernet port does not support auto- negotiation or turns off this feature, the switch determines the connection speed by detecting the signal on the cable and using half duplex mode. When the switch’s auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and duplex mode when making a connection, thus requiring you to make sure that the settings of the peer Ethernet port are the same in order to connect.

A concentration of traffic on a port decreases port bandwidth and overflows buffer memory causing packet discards and frame losses. Flow Control is used to regulate transmission of signals to match the bandwidth of the receiving port.

The switch uses IEEE802.3x flow control in full duplex mode and backpressure flow control in half duplex mode.

IEEE802.3x flow control is used in full duplex mode to send a pause signal to the sending port, causing it to temporarily stop sending signals when the receiving port memory buffers fill.

Back Pressure flow control is typically used in half duplex mode to send a "collision" signal to the sending port (mimicking a state of packet collision) causing the sending port to temporarily stop sending signals and resend later. Select Flow Control to enable it.

This priority value is added to incoming frames without a (802.1p) priority queue tag. See Priority Queue Assignment in Table 6-3 for more information. See also Priority Queue Assignment in Switch Setup and Queuing Method for related information.

VLAN The type of screen you see here depends on the VLAN Type you selected in the Switch Setup screen. This chapter shows you how to configure 802.1Q tagged and port-based VLANSs. See the General, Switch and IP Setup chapter for more information.

7.1 Introduction to IEEE 802.1Q Tagged VLAN Tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a frame across bridges - they are not confined to the switch on which they were created. The VLANS can be created statically by hand or dynamically through GVRP. The VLAN ID associates a frame with a specific VLAN and provides the information that switches need to process the frame across the network. A tagged frame is four bytes longer than an untagged frame and contains two bytes of TPID (Tag Protocol Identifier, residing within the type/length field of the Ethernet frame) and two bytes of TCI (Tag Control Information, starts after the source address field of the Ethernet frame).

The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet switches. If a frame received at an Ethernet port has a CFI set to 1, then that frame should not be forwarded as it is to an untagged port. The remaining twelve bits define the VLAN ID, giving a possible maximum number of 4,096 (212) VLANSs. Note that user priority and VLAN ID are independent of each other. A frame with VID (VLAN Identifier) of null (0) is called a priority frame, meaning that only the priority level is significant and the default VID of the ingress port is given as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and value 4095 (FFF) is reserved, so the maximum possible VLAN configurations are 4,094

TPID User Priority CFI [VLANID 2 Bytes |3 Bits 1 Bit |12 bits

7.1.1 Forwarding Tagged and Untagged Frames

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

7.1.2 Automatic VLAN Registration

GARP and GVRP are the protocols used to automatically register VLAN membership across switches.

Dimension ES-3024 Ethernet Switch

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

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

GVRP GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for switches to register necessary VLAN members on ports across the network. Enable this function to permit VLANSs groups beyond the

Please refer to the following table for common GARP terminology.

7.1.3 Port VLAN Trunking

Enable VLAN Trunking on a port to allow frames belonging to unknown VLAN groups to pass through that port. This is useful if you want to set up VLAN groups on end devices without having to configure the same VLAN groups on intermediary devices.

Refer to the following figure. Suppose you want to create VLAN groups 1 and 2 (VI and V2) on devices A and B. Without VLAN Trunking, you must configure VLAN groups 1 and 2 on all intermediary switches C, D and E; otherwise they will drop frames with unknown VLAN group tags. However, with VLAN Trunking enabled on a port(s) in each intermediary switch you only need to create VLAN groups in the end devices (A and B). C, D and E automatically allow frames with VLAN group tags 1 and 2 (VLAN groups that are unknown to those switches) to pass through their VLAN trunking port(s).

7.3 Introduction to Port-based VLANS Port-based VLANSs are VLANSs where the packet forwarding decision is based on the destination MAC address and its associated port.

Port-based VLANSs require allowed outgoing ports to be defined for each port. Therefore, if you wish to allow two subscriber ports to talk to each other, for example, between conference rooms in a hotel, you must define the egress (an egress port is an outgoing port, that is, a port through which a data packet leaves) for both ports.

Port-based VLANS are specific only to the switch on which they were created.

The port-based VLAN setup screen is shown next. The CPU management port forms a VLAN with all Ethernet ports.

All connected means all ports can communicate with each other, that is, there are no virtual LANSs. All incoming and outgoing ports are selected (Figure 7-8). This option is the most flexible but also the least secure.

Port isolation means that each port can only communicate with the CPU management port and cannot communicate with each other. All incoming ports are selected while only the CPU outgoing port is selected (Figure 7-9). This option is the most limiting but also the most secure.

After you make your selection, click Apply (top right of screen) to display the screens as mentioned above. You can still customize these settings by adding/deleting incoming or outgoing ports, but you must also click Apply at the bottom of the screen.

These are the ingress ports; an ingress port is an incoming port, that is, a port through which a data packet enters. If you wish to allow two subscriber ports to talk to each other, you must define the ingress port for both ports. The numbers in the top row denote the incoming port for the corresponding port listed on the left (its outgoing port). CPU refers to the switch management port. By default it forms a VLAN with all Ethernet ports. If it does not form a VLAN with a particular port then the switch cannot be managed from that port.

These are the egress ports; an egress port is an outgoing port, that is, a port through which a data packet leaves. If you wish to allow two subscriber ports to talk to each other, you must define the egress port for both ports. CPU refers to the switch management port.

Chapter 8 Static MAC Forward Setup

Use these screens to configure static MAC address forwarding.

8.1 Introduction to Static MAC Forward Setup

A static MAC address entry is an address that has been manually entered in the MAC address learning table. Static MAC addresses do not age out. When you set up static MAC address rules, you are setting static MAC addresses for a port. Devices that match static MAC address rules on a port can only receive traffic on that port

and cannot receive traffic on other ports. This may reduce unicast flooding.

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

10.1.1 STP Terminology

The root bridge is the base of the spanning tree: it is the bridge with the lowest identifier value (MAC address).

Path cost is the cost of transmitting a frame onto a LAN through that port. It is assigned according to the speed of the link to which a port is attached. The slower the media, the higher the cost - see the next table.

Table 10-1 STP Path Costs

LINK SPEED | RECOMMENDED VALUE RECOMMENDED RANGE ALLOWED RANGE Path Cost | 4Mbps 250 100 to 1000 1 to 65535 Path Cost | 10Mbps 100 50 to 600 1 to 65535 Path Cost | 16Mbps 62 40 to 400 1 to 65535 Path Cost | 100Mbps 19 10 to 60 1 to 65535 Path Cost | 1Gbps 3 to 10 1 to 65535 Path Cost | 10Gbps 1to5 1 to 65535

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

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

bridges connected to the LAN.

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

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

Spanning Tree Protocol

Once a stable network topology has been established, all bridges listen for Hello BPDUSs (Bridge Protocol Data Units) transmitted from the root bridge. If a bridge does not get a Hello BPDU after a predefined interval (Max Age), the bridge assumes that the link to the root bridge is down. This bridge then initiates negotiations with other bridges to reconfigure the network to re-establish a valid network topology.

10.1.3 STP Port States

STP assigns five port states (see next table) to eliminate packet looping. A bridge port is not allowed to go directly from blocking state to forwarding state so as to eliminate transient loops.

Table 10-2 STP Port States

PORT STATE DESCRIPTION Disabled STP is disabled (default). Blocking Only configuration and management BPDUSs are received and processed. Listening All BPDUSs are received and processed. Learning All BPDUSs are received and processed. Information frames are submitted to the learning process but not forwarded. Forwarding All BPDUSs are received and processed. All information frames are received and forwarded.

Click Advanced Application and then Spanning Tree Protocol in the navigation panel to display the STP status as shown in the screen next.

The following table describes the labels in this screen.

Table 10-3 Spanning Tree Protocol: Status

LABEL DESCRIPTION Spanning Tree Protocol |This field displays Running if STP is activated. Otherwise, it displays Down.

Bridge Root refers to the base of the spanning tree (the root bridge). Our Bridge is this switch. This switch may also be the root bridge.

Bridge ID This is the unique identifier for this bridge, consisting of bridge priority plus MAC address. This ID is the same for Root and Our Bridge if the switch is the root switch.

Hello Time (second) This is the time interval (in seconds) at which the root switch transmits a configuration message. The root bridge determines Hello Time, Max Age and Forwarding Delay

Max Age (second) This is the maximum time (in seconds) a switch can wait without receiving a configuration message before attempting to reconfigure.

Spanning Tree Protocol 10-3

This is the time (in seconds) the root switch will wait before changing states (that is, listening to learning to forwarding).

This is the path cost from the root port on this switch to the root switch.

Port ID This is the priority and number of the port on the switch through which this switch must communicate with the root of the Spanning Tree.

Click Stop to halt STP statistic polling.

Active Bridge Priority

The following table describes the labels in this screen.

Table 10-4 Spanning Tree Protocol: Configuring

LABEL DESCRIPTION Active

Select this check box to activate STP.

Bridge priority is used in determining the root switch, root port and designated port. The switch with the highest priority (lowest numeric value) becomes the STP root switch. If all switches have the same priority, the switch with the lowest MAC address will then become the root switch. The allowed range is 0 to 65535.

The lower the numeric value you assign, the higher the priority for this bridge.

Bridge Priority determines the root bridge, which in turn determines Hello Time, Max Age and Forwarding Delay.

Hello Time This is the time interval in seconds between BPDU (Bridge Protocol Data Units) configuration message generations by the root switch. The allowed range is 1 to 10 seconds.

Max Age This is the maximum time (in seconds) a switch can wait without receiving a BPDU before attempting to reconfigure. AIl switch ports (except for designated ports) should receive BPDUSs at regular intervals. Any port that ages out STP information (provided in the last BPDU) becomes the designated port for the attached LAN. [fit is a root port, a new root port is selected from among the switch ports attached to the network. The allowed range is 6 to 40 seconds.

Forwarding This is the maximum time (in seconds) a switch will wait before changing states. This delay is

Delay required because every switch must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that would make it return to a blocking state; otherwise, temporary data loops might result. The allowed range is 4 to 30 seconds.

As a general rule: 2 * (Forward Delay - 1) >= Max Age >= 2 * (Hello Time + 1)

Port This field displays the port number.

Active Select this check box to activate STP on this port.

Priority Configure the priority for each port here.

Priority decides which port should be disabled when more than one port forms a loop in a switch. Ports with a higher priority numeric value are disabled first. The allowed range is between 0 and 255 and default value is 128.

Path Cost Path cost is the cost of transmitting a frame on to a LAN through that port. lt is assigned according to the speed of the bridge. The slower the media, the higher the cost - see Table 10-1 for more information.

Chapter 14 Link Aggregation

This chapter shows you how to logically aggregate physical links to form one logical, higher-bandwidth link.

14.1 Introduction to Link Aggregation

Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity link. You may want to trunk ports if for example, it is cheaper to use multiple lower-speed links than to under-utilize a high-speed, but more costly, single-port link.

However, the more ports you aggregate then the fewer available ports you have. A link aggregation group is one logical link containing multiple ports.

The first port must be physically connected when forming a trunk group.

Table 14-1 Link Aggregation Groups

LINK AGGREGATION BEGINNING-TO-END PORT RANGE GROUP 1 1to8 2 9 to 16 3 17 to 24 4 25 and 26 (the uplink ports) 5 S1 and S2 (the stacking ports)

141.1 Dynamic Link Aggregation

The ES-3024 adheres to the 802.3ad standard for static and dynamic (LACP) port trunking.

The ES-3024 supports the link aggregation IEEE802.3ad standard. This standard describes the Link Aggregate Control Protocol (LACP), which is a protocol that dynamically creates and manages trunk groups.

When you enable LACP link aggregation on a port, the port can automatically negotiate with the ports at the remote end of a link to establish trunk groups. LACP also allows port redundancy, that is, if an operational port fails, then one of the “standby” ports become operational without user intervention

You must connect all ports point-to-point to the same Ethernet switch and configure the ports for LACP trunking.

LACP only works on full-duplex links.

All ports in the same trunk group must have the same media type, speed, duplex mode and flow control settings.

Link Aggregation 14-1

15.1Introduction to Authentication

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

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

Figure 15-1 RADIUS Server

15.2Configuring Port Authentication

To enable port authentication, first activate IEEE802.1x security (both on the ES-3024 and the port(s)) then configure the RADIUS server settings.

Click Port Authentication under Advanced Application in the navigation panel to display the screen as shown.

? At the time of writing, Windows XP of the Microsoft operating systems supports 802.1x. See the Microsoft web site for information on other Windows operating system support. For other operating systems, see its documentation. If your operating system does not support 802.1x, then you may need to install 802.1x client software.

Chapter 16 Port Security

This chapter shows you how to set up port security.

16.1 About Port Security

Port security allows only packets with dynamically learned MAC addresses and/or configured static MAC addresses to pass through a port on the switch. The switch can learn up to 16K MAC addresses in total with no limit on individual ports other than the sum cannot exceed 16K.

For maximum port security, enable this feature, disable MAC address learning and configure static MAC address(es) for a port. It is not recommended you disable Port Security together with MAC address learning as this will result in many broadcasts.

16.2Port Security Setup

Click Port Security in the navigation panel to display the screen as shown.

The following table describes the labels in this screen.

Select this check box to enable MAC address learning on this port.

MAC address learning reduces outgoing broadcast traffic. For MAC address learning to occur on a port, the port itself must be active with address learning enabled.

Learned MAC Use this field to limit the number of (dynamic) MAC addresses that may be learned on a port. For example, if you set this field to "5" on port 2, then only the devices with these five learned

Address MAC addresses may access port 2 at any one time. À sixth device would have to wait until one of the five learned MAC addresses aged out. MAC-address aging out time can be set in the Switch Setup screen. The valid range is from “0” to “254”. “0” means this feature is disabled, so the switch will learn MAC addresses up to the global limit of 16K.

17.3About SNMP Simple Network Management Protocol is a protocol used for exchanging management information between network switches. SNMP is a member of TCP/IP protocol suite. À manager station can manage and monitor the ES-3024 through the network via SNMP version one (SNMPv1) and/or SNMP version 2c. The next figure illustrates an SNMP management operation. SNMP is only available if TCP/IP is configured.

MANAGER SNMP AGENT AGENT AGENT Managed Device Managed Device Managed Device

Figure 17-3 SNMP Management Model An SNMP managed network consists of two main components: agents and a manager.

An agent is a management software module that resides in a managed switch (the ES-3024). An agent translates the local management information from the managed switch into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices.

The managed devices contain object variables/managed objects that define each piece of information to be collected about a switch. Examples of variables include such as number of packets received, node port status etc. A

Dimension ES-3024 Ethernet Switch

Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects.

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

Table 17-2 SNMP Commands

COMMAND DESCRIPTION Get Allows the manager to retrieve an object variable from the agent. GetNext Allows the manager to retrieve the next object variable from a table or list within an agent. In

SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations.

Set Allows the manager to set values for object variables within an agent.

Trap Used by the agent to inform the manager of some events.

17.3.1 Supported MIBs

MIBs let administrators collect statistics and monitor status and performance.

The ES-3024 supports the following MIBs:

> SNMP MIBII (RFC 1213) > RFC 1157 SNMP vl

> RFC 1493 Bridge MIBs > RFC 1643 Ethernet MIBs

> RFC 1757 RMON > SNMPv2, SNMPv2c or later version, compliant with RFC 2011

SNMPv2 MIB for IP, RFC 2012 SNMPv2 MIB for TCP, RFC 2013 SNMPv2 MIB for UDP

The ES-3024 sends traps to an SNMP manager when an event occurs. SNMP traps supported are outlined in the following table.

Table 17-3 SNMP Traps

GENERIC TRAP SPECIFIC TRAP DESCRIPTION

0 (Cold Start) [0] This trap is sent when the ES-3024 is turned on.

1 (WarmStart) [0] This trap is sent when the ES-3024 restarts.

2 (linkDown) [0] This trap is sent when the Ethernet link is down.

3 (linkUp) [0] This trap is sent when the Ethernet link is up.

4 [o] This trap is sent when an SNMP request comes from non- (authenticationFailure) authenticated hosts.

This chapter introduces SPQ and WFQ.

18.1Introduction to Queuing

Queuing is used to help solve performance degradation when there is network congestion. Use the Queuing Method screen to configure queuing algorithms for outgoing traffic. See also Priority Queue Assignment in Switch Setup and 802.1p Priority in Port Setup for related information.

Queuing algorithms allow switches to maintain separate queues for packets from each individual source or flow and prevent a source from monopolizing the bandwidth.

The switch has four physical queues, Q0 to Q3. Q3 has the highest priority and Q0 has the lowest.

Table 18-1 Physical Queue Priority

QUEUE PRIORITY Q3 1 (Highest) Q2 2 Q1 3 Q0 4 (Lowest)

18.1.1 Strict Priority Queuing (SPQ)

Strict Priority Queuing (SPQ) services queues based on priority only. As traffic comes into the switch, traffic on the highest priority queue, Q3 is transmitted first. When that queue empties, traffic on the next highest-priority queue, Q2 is transmitted until Q2 empties, and then traffic is transmitted on Q1 and so on. If higher priority queues never empty, then traffic on lower priority queues never gets sent. SPQ does not automatically adapt to changing network requirements.

18.12 Weighted Fair Queuing (WFQ)

Weighted Fair Queuing (WFQ) services queues based on their priority and queue weight (the number you configure in the % field — see Figure 18-1). WFQ is activated only when a port has more traffic than it can handle. Queues with larger weights get more service than queues with smaller weights. This queuing mechanism is highly efficient in that it divides any available bandwidth across the different traffic queues.

This parameter specifies the IP network address of the final destination. Routing is always based on network number. If you need to specify a route to a single host, use a subnet mask of 255.255.255.255 in the subnet mask field to force the network number to be identical to the host ID.

IP Subnet Mask |Enter the subnet mask for this destination.

Gateway IP Enter the IP address of the gateway. The gateway is an immediate neighbor of your switch that

Address will forward the packet to the destination. The gateway must be a router on the same segment as your switch.

Metric The metric represents the “cost” of transmission for routing purposes. IP routing uses hop count as the measurement of cost, with a minimum of 1 for directly connected networks. Enter a number that approximates the cost for this link. The number need not be precise, but it must be between 1 and 15. In practice, 2 or 3 is usually a good number.

Add Click Add to save the new rule to the switch. It then displays in the summary table at the bottom of the screen.

20.7Command Line FTP This section shows some examples of uploading to or downloading files from the switch using FTP commands. First, understand the filename conventions.

20.7.1 Filename Conventions

The configuration file (often called the romfile or rom-0) contains the factory default settings in the screens such as password, switch setup, IP Setup, etc. It arrives from ZyXEL with a “rom” filename extension. Once you have customized the switch's settings, they can be saved back to your computer under a filename of your choosing.

ZyNOS (ZyXEL Network Operating System sometimes referred to as the “ras” file) is the system firmware and has a “bin” filename extension.

Table 20-1 Filename Conventions

FILE TYPE INTERNAL | EXTERNAL DESCRIPTION NAME NAME Configuration File | Rom-0 *rom This is the configuration filename on the switch. Uploading the

rom-0 file replaces the entire ROM file system, including your switch configurations, system-related data (including the default password), the error log and the trace log.

Firmware Ras *.bin This is the generic name for the ZyNOS firmware on the switch.

Example FTP Commands

ftp> put firmware.bin ras

This is a sample FTP session showing the transfer of the computer file " firmware.bin" to the switch .

ftp> get rom-0 config.cfq This is a sample FTP session saving the current configuration to a file called “config.cfg” on your computer.

If your (T)FTP client does not allow you to have a destination filename different than the source, you will need to rename them as the switch only recognizes “rom-0” and “ras”. Be sure you keep unaltered copies of both files for later use.

Be sure to upload the correct model firmware as uploading the wrong model firmware may damage your device.

20.7.2 FTP Command Line Procedure

Step 1. Launch the FTP client on your computer.

Step 2. Enter “open”, followed by a space and the IP address of your switch.

Dimension ES-3024 Ethernet Switch

Step 3. Press [ENTER] when prompted for a username. Step 4. Enter your password as requested (the default is 1234”). Step 5. Enter “bin” to set transfer mode to binary.

Step 6. Use “put” to transfer files from the computer to the switch, for example, “put firmware.bin ras” transfers the firmware on your computer (firmware.bin) to the switch and renames it “ras”. Similarly, “put config.rom rom-0” transfers the configuration file on your computer (config.rom) to the switch and renames it “rom-0”. Likewise “get rom-0 config.rom” transfers the configuration file on the switch to your computer and renames it “config.rom.” See earlier in this chapter for more information on filename conventions.

Step 7. Enter “quit” to exit the ftp prompt.

20.7.3 GUl-based FTP Clients

The following table describes some of the commands that you may see in GUI-based FTP clients.

Table 20-2 General Commands for GUl-based FTP Clients

COMMAND DESCRIPTION Host Address Enter the address of the host server. Login Type Anonymous.

This is when a user I.D. and password is automatically supplied to the server for anonymous access. Anonymous logins will work only if your ISP or service administrator has enabled this option.

The server requires a unique User ID and Password to login.

Transfer Type Transfer files in either ASCII (plain text format) or in binary mode. Configuration and firmware files should be transferred in binary mode.

Initial Remote Directory Specify the default remote directory (path).

Initial Local Directory Specify the default local directory (path).

20.7.4 FTP over WAN Restrictions

FTP over WAN will not work when: e Telnet service is disabled in Secured Client Sets.

e The IP address(es) in the Secured Client Sets menu does not match the client IP address. If it does not match, the switch will disconnect the Telnet session immediately.

23.1Introduction to Filtering Database

The Filtering Database shows how frames are forwarded or filtered across the switch’s ports. It shows what device

MAC address, belonging to what VLAN group (if any) is forwarded to which port(s) and whether the MAC address is dynamic (learned by the switch) or static (manually entered in Static MAC Forwarding).

The switch uses the Filtering Database to determine how to forward frames. See the following figure. 1. The switch examines a received frame and learns the port on which this source MAC address came.

2. The switch checks to see if the frame's destination MAC address matches a source MAC address already learned in the Filtering Database.

> _Ifthe switch has already learned the port for this MAC address, then it forwards the frame to that port.

> Ifthe switch has not already learned the port for this MAC address, then the frame is flooded to all ports. Too much port flooding leads to network congestion.

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

24.1Introduction to ARP Table

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

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

24.1.1 How ARP Works

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

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

Introduction to CLI This chapter introduces line commands and gives a summary of commands available.

25.1 Command Line Interface Overview

In addition to the web configurator, you can use line commands to configure the switch. It is recommended that you use the web configurator for everyday management of the switch and that you use line commands for advanced switch diagnosis and troubleshooting. If you have problems with your switch, customer support may request that you issue some of these commands to assist them in troubleshooting.

You can use the “config save” command to save 802.1Q, STP, Cluster and IP configuration changes to non-volatile memory (Flash). These changes are effective after you restart the switch.

However you cannot use “config save” for all other line command configurations. These are saved in volatile memory (DRAM), so are not effective after you restart the switch.

25.1.1 Accessing the Command Line Interface

There are two ways to access the command line interface on the ES-3024: e Telnet to the switch

e Connect a computer to the console port and use terminal emulation software configured to the following parameters:

"__ VT100 terminal emulation "9600 bps

"No parity, 8 data bits, 1 stop bit “__Noflow control 25.1.2 Command Conventions

The system uses a one-level command structure. You must type the full command every time, as follows. 192.168.1.1> <command>

For instance, the following example shows how to enable GVRP.

192.168.1.1> sys sw gvrp enable

The conventions for typing in most CI commands are shown next.

command <interface|device> subcommand [parameter]

command subcommand [parameter]

Type all commands as displayed on the screen.

Dimension ES-3024 Ethernet Switch

25.1.3 Command Syntax Conventions

1. Command keywords are in courier new font. 2. The | symbol means “or

3. Required fields in a command are enclosed in angle brackets <>. Use the following command to turn the system monitor on or off.

sys monitor enable <on/off>

4. Optional fields in a command are enclosed in square brackets [], for example, year, month and day are optional in the following command. This command just displays the date if you don’t specify the year, month and day parameters.

sys date [year month day]

5. Commands can be abbreviated to the smallest unique string that differentiates the command. For example the “system date” command could be abbreviated to “s d”.

Type “help” or “?” to display a list of valid commands or type a command followed by “help” or “?” to display a list of associated subcommands.

The following figure shows a sample help information.

ES-3024> ? Valid commands are: sys exit ip

This chapter describes the IEEE 802.1Q Tagged VLAN and associated commands. Use the “config save” command to save configuration changes.

27.1IÈEE 802.1Q Tagged VLAN Overview

See the VLAN chapter for more information on VLANSs. There are two kinds of tagging: 1. Explicit Tagging

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

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

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

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

27.2Filtering Databases

A filtering database stores and organizes VLAN registration information useful for switching frames to and from a switch. À filtering database consists of a static entries (Static VLAN or SVLAN table) and dynamic entries (Dynamic VLAN or DVLAN table).

27.2.1 Static Entries (SVLAN Table)

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

27.2.2 Dynamic Entries (DVLAN Table)

Dynamic entries are learned by the switch and cannot be created or updated by administrators. The switch learns this information by observing what port, source address and VLAN ID (or VID) is associated with a frame. Entries are added and deleted using GARP VLAN Registration Protocol (GVRP), where GARP is the Generic Attribute Registration Protocol.

27.3Configuring Tagged VLAN IÉEE 802.1Q Tagged VLAN 27-1

Dimension ES-3024 Ethernet Switch

The following procedure shows you how to configure tagged VLAN.

Step 1. Use the IEEE 802.1Q tagged VLAN commands to configure tagged VLAN for the switch.

e Usethesys sw vlanlq svlan setentry command to configure a VLAN ID for each port on the switch.

e Usethesys sw vlanlq svlan active command when you are finished configuring the VLAN (see the last step).

e Usethesys sw vlanla port defaultVID command to set the VLAN ID you created for a port to that specific port in the PVID table.

e Usethesys sw vlanlq svlan active command to activate the VLAN IDs.

ES-3024> sys sw vlanlq svlan setentry upl 2000 24 fixed tag for newly create VLAN, please use svlan active <VID> to activate this entry

Figure 27-1 Tagged VLAN Configuration and Activation Example Step 2. Configure your management VLAN.

e Usethesys sw vlanlq svlan setentry command to configure a VLAN ID (VID 3 in this example) for managing the switch (the “management” or “CPU” VLAN).

e Usethesys sw vlanlq svlan active command to activate the new management VLAN ID.

ES-3024> sys sw vlanlq svlan setentry example 3 24 fixed tag

Figure 27-2 CPU VLAN Configuration and Activation Example Step 3. Perform the procedure below to complete the VLAN setup. a. Telnet to the operational IP address of the switch. b. Usethesys sw vlanlq svlan cpu command to set VID 3 as the management VLAN. c. Usethesys sw svlan delentry command to remove the default VLAN ID (1).

27.4IEEE VLAN1Q Tagged VLAN Configuration Commands

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

Syntax: sys sw garp status This command shows the switch’s GARP timer settings, including the join, leave and leave all timers.

sys sw garp timer timer <join timer(ms)> <leave timer(ms)> <leave all timer<ms>

This sets the duration of the Join Period timer for GVRP in milliseconds. Each port has a Join Period timer. The allowed Join Time range is between 100 and 32767 milliseconds; the default is 200 milliseconds.

This sets the duration of the Leave Period timer for GVRP in milliseconds. Each port has a single Leave Period timer. Leave Time must be two times larger than Join Timer; the default is 600 milliseconds.

<leave all timer<ms>= This sets the duration of the Leave All Period timer for GVRP in milliseconds. Each port has a single Leave All Period timer. Leave All Timer must be larger than Leave Timer; the default is 10000 milliseconds.

IÉEE 802.1Q Tagged VLAN 27-3

Dimension ES-3024 Ethernet Switch

This command sets the switch’s GARP timer settings, including the join, leave and leave all timers.

Switches join VLANSs by making a declaration. A declaration is made by issuing a Join message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All message terminates all registrations. GARP

timers set declaration timeout values.

The following example sets the Join Timer to 300 milliseconds, the Leave Timer to 800 milliseconds and the Leave All Timer to 11000 milliseconds.

Figure 27-5 garp timer Command Example

Syntax: sys sw gvrp status This command shows the switch’s GVRP settings.

This command turns on GVRP in order to propagate VLAN information beyond the switch.

Syntax: sys sw gvrp disable

This command turns off GVRP so that the switch does not propagate VLAN information to other switches.

27.4.6 vlan1q port status

The following example shows the settings for port 1.

Syntax: sys sw vlanlq port defaultVID <port> <VID> where <port> = À port number <VID> = The VLAN ID. Valid parameter range = [1 — 4094].

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

The following example sets the default VID of port 1 to 2000.

ES-3024> sys sw vlanlq port defaultVID 1 2000

The following example sets port 2 to accept only tagged frames.

The following example turns off GVRP for port 2.

<VID> = The VLAN ID. Valid parameter range = [1 — 40941].

This command sets the management VLAN (CPU). You can only use ports that are members of this management

VLAN in order to manage the switch.

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

ES-3024> sys sw vlanlq svlan cpu 2

Figure 27-11 vlan1q svlan cpu Command Example

À name to identify the SVLAN entry. The VLAN ID [1 — 4094]. This is the switch port number.

This is the registrar administration control flag. Valid parameters = [fixed, forbidden, normal].

Enter fixed to register a <port #> to the static VLAN table with <vid>. Enter normal to confirm registration ofthe <port #> to the static VLAN table with <vid>.

Enter forbidden to block a <port #> from joining the static VLAN table with <vid>.

This is the tag control flag. Valid parameters = [tagluntag].

Enter tag to tag outgoing frames. Enter untag to send outgoing frames without a tag.

This command adds or modifies an entry in the static VLAN table. Display your configuration by using the sys sw vlaniq svlan list command. An example of a configuration is shown next.

Modify a Static VLAN Table Example

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

vlanigq svlan setentry vlanigq svlan setentry

Figure 27-12 Modifying the Static VLAN Example

Forwarding Process Example

First the switch checks the VLAN ID (VID) of tagged frames or assigns temporary VIDs to untagged frames (see Section 27.4.7).

The switch then checks the VID in a frame’s tag against the SVLAN table.

The switch notes what the SVLAN table says (that is, the SVLAN tells the switch whether or not to forward a frame and if the forwarded frames should have tags).

Then the switch applies the port filter to finish the forwarding decision. This means that frames may be dropped even if the SVLAN says to forward them. Frames might also be dropped if they are sent to a CPE (customer premises equipment) DSL device that does not accept tagged frames.

IÉEE 802.1Q Tagged VLAN

Dimension ES-3024 Ethernet Switch

Untagged Frames Step 1. An untagged frame comes in from the LAN. Step 2. The switch checks the PVID table and assigns a temporary VID of 1.

Step 3. The switch ignores the port from which the frame came, because the switch does not send a frame to the port from which it came. The switch also does not forward frames to “forbidden” ports.

Step 4. Ifafter looking at the SVLAN, the switch does not have any ports to which it will send the frame, it won’t check the port filter.

27.4.12 vlan1q svlan delentry

Syntax: sys sw vlanlq svlan delentry <VID> where <VID> = The VLAN ID [1 — 4094]. This command deletes the specified VLAN ID entry from the static VLAN table

The following example deletes entry 2 in the static VLAN table.

vlanlgq svlan delentry 2

Figure 27-13 vlan1q svlan delentry Command Example

27.5vlan1q svlan active

Syntax: sys sw vlanlq svlan active <VID>

This command shows the IEEE 802.1Q Tagged SVLAN (Static VLAN) table.

27-8 IÉEE 802.1Q Tagged VLAN Dimension ES-3024 Ethernet Switch

An example is shown next. For the AdCt1 section of the last column, “-“ is a port set to normal, “x” is a forbidden port and “F” is a fixed port.

For the TagCt1 section of the last column, “T“ is a tagged port, “U” is an untagged port.

ES-3024> sys sw vlanlq svlan list

<all1|VID|start Specify either all of the VLAN entries (a11), a single VLAN ID (VID) ora _VIDIend_VID>= range of VLAN IDs starting from a certain VID (start_VID) or a range of VLAN Ids ending at a specific VID (end_VID).

This command shows the current IEEE 802.1Q Tagged VLAN table or a specific part ofit. An example is shown next.

For the EgressPort section of the last column, “E” is an egress port for this VLAN, “-“ is not an egress port for this VLAN.

Figure 27-15 vlan1q svlan list Command Example

See the following example shows the default VLAN settings. The default VLAN allows all ports to connect to each other and sets them to send untagged packets.
