SMC may, at its own discretion, repair or replace any product not operating as warranted with a similar or functionally equivalent product, during the applicable warranty term. SMC will endeavor to repair or replace any product returned under warranty within 30 days of receipt of the product.
The standard limited warranty can be upgraded to a Limited Lifetime* warranty by registering new products within 30 days of purchase from SMC or its Authorized Reseller. Registration can be accomplished via the enclosed product registration card or online via the SMC web site. Failure to register will not affect the standard limited warranty. The Limited Lifetime warranty covers a product during the Life of that Product, which is defined as the period of time during which the product is an “Active” SMC product. A product is considered to be “Active” while it is listed on the current SMC price list. As new technologies emerge, older technologies become obsolete and SMC will, at its discretion, replace an older product in its product line with one that incorporates these newer technologies. At that point, the obsolete product is discontinued and is no longer an “Active” SMC product.

All products that are replaced become the property of SMC. Replacement products may be either new or reconditioned. Any replaced or repaired product carries either a 30-day limited warranty or the remainder of the initial warranty, whichever is longer. SMC is not responsible for any custom software or firmware, configuration information, or memory data of Customer contained in, stored on, or integrated with any products returned to SMC pursuant to any warranty. Products returned to SMC should have any customer-installed accessory or add-on components, such as expansion modules, removed prior to returning the product for replacement. SMC is not responsible for these items if they are returned with the product.
Customers must contact SMC for a Return Material Authorization number prior to returning any product to SMC. Proof of purchase may be required. Any product returned to SMC without a valid Return Material Authorization (RMA) number clearly marked on the outside of the package will be returned to customer at customer’s expense. For warranty claims within North America, please call our toll-free customer support number at (800) 762-4968. Customers are responsible for all shipping charges from their facility to SMC.

Required Connections

The switch provides an RS-232 serial port that enables a connection to a PC or terminal for monitoring and configuring the switch. A null-modem console cable is provided with the switch.
Attach a VT100-compatible terminal, or a PC running a terminal emulation program to the switch. You can use the console cable provided with this package, or use a null-modem cable that complies with the wiring assignments shown in Appendix B.
To connect a terminal to the console port, complete the following steps:
1. Connect the console cable to the serial port on a terminal, or a
PC running terminal emulation software, and tighten the captive retaining screws on the DB-9 connector.
2. Connect the other end of the cable to the RS-232 serial port on
the switch.
3. Make sure the terminal emulation software is set as follows:
Select the appropriate serial port (COM port 1, or COM port 2).
Set the data rate to 9600 baud.
Set the data format to 8 data bits, 1 stop bit, and no parity.
Set flow control to none.
Set the emulation mode to VT100.
When using HyperTerminal, select Terminal keys, not Windows keys.

WITCH MANAGEMENT
Note: When using HyperTerminal with Microsoft® Windows®
2000, make sure that you have Windows 2000 Service Pack 2 or later installed. Windows 2000 Service Pack 2 fixes the problem of arrow keys not functioning in HyperTerminal’s VT100 emulation. See www.microsoft.com for information on Windows 2000 service packs.
4. Once you have set up the terminal correctly, the console login screen will be displayed.
Note: Refer to “IGMP Snooping Commands” on page 3-61 for a
complete description of console configuration options.
For a description of how to use the CLI, see “Using the Command Line Interface” on page 3-1. For a list of all the CLI commands and detailed information on using the CLI, refer to “Command Groups” on page 3-10.

Remote Connections

Prior to accessing the switch’s onboard agent via a network connection, configure it with a valid IP address, subnet mask, and default gateway using a console connection, DHCP or BOOTP protocol.
The IP address for this switch is unassigned by default. To manually configure this address or enable dynamic address assignment via DHCP or BOOTP, see “Setting an IP Address” on page 1-7.
Note: This switch supports four concurrent Telnet sessions.
After configuring the switch’s IP parameters, you can access the onboard configuration program from anywhere within the attached network. The onboard configuration program can be accessed using Telnet from any computer attached to the network. The switch can also be managed by any computer using a Web

ASIC CONFIGURATION
browser (Internet Explorer 5.0 or above, or Netscape Navigator 6.2 or above), or from a network computer using network management software.
Note: The onboard program only provides access to basic
configuration functions. To access the full range of SNMP management functions, you must use SNMP-based network management software.

Basic Configuration

Console Connection

The CLI program provides two different command levels — normal access level (Normal Exec) and privileged access level (Privileged Exec). The commands available at the Normal Exec level are a limited subset of those available at the Privileged Exec level and only allow you to display information and use basic utilities. To fully configure switch parameters, you must access the CLI at the Privileged Exec level.
Access to both CLI levels are controlled by user names and passwords. The switch has a default user name and password for each level. To log into the CLI at the Privileged Exec level using the default user name and password, perform these steps:
1. To initiate your console connection, press <Enter>. The “User Access Verification” procedure starts.
2. At the Username prompt, enter “admin.”
3. At the Password prompt, also enter “admin.” (The password characters are not displayed on the console screen.)
4. The session is opened and the CLI displays the “Console#” prompt indicating you have access at the Privileged Exec level.

WITCH MANAGEMENT

Setting Passwords

Note: If this is your first time to log into the CLI program, you
should define new passwords for both default user names using the “username” command, record them and put them in a safe place.
Passwords can consist of up to 8 alphanumeric characters and are case sensitive. To prevent unauthorized access to the switch, set the passwords as follows:
1. Open the console interface with the default user name and password “admin” to access the Privileged Exec level.
2. Type “configure” and press <Enter>.
3. Type “username guest password 0 password,” for the Normal Exec level, where password is your new password. Press <Enter>.
4. Type “username admin password 0 password,” for the Privileged Exec level, where password is your new password. Press <Enter>.

ASIC CONFIGURATION

Setting an IP Address

You must establish IP address information for the switch to obtain management access through the network. This can be done in either of the following ways:
Manual — You have to input the information, including IP address and subnet mask. If your management station is not in the same IP subnet as the switch, you will also need to specify the default gateway router.
Dynamic — The switch sends IP configuration requests to BOOTP or DHCP address allocation servers on the network.
Note: Only one VLAN interface can be assigned an IP address
(the default is VLAN 1). This defines the management VLAN, the only VLAN through which you can gain management access to the switch. If you assign an IP address to any other VLAN, the new IP address overrides the original IP address and this becomes the new management VLAN.
Manual Configuration
You can manually assign an IP address to the switch. You may also need to specify a default gateway that resides between this device and management stations that exist on another network segment. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods. Anything outside this format will not be accepted by the CLI program.
Note: The IP address for this switch is unassigned by default.
Before you can assign an IP address to the switch, you must obtain the following information from your network administrator:
IP address for the switch

WITCH MANAGEMENT
Default gateway for the network
Network mask for this network
To assign an IP address to the switch, complete the following steps:
1. From the Privileged Exec level global configuration mode prompt, type “interface vlan 1” to access the interface-configuration mode. Press <Enter>.
2. Type “ip address ip-address netmask,” where “ip-address” is the switch IP address and “netmask” is the network mask for the network. Press <Enter>.
3. Type “exit” to return to the global configuration mode prompt. Press <Enter>.
4. To set the IP address of the default gateway for the network to which the switch belongs, type “ip default-gateway gateway,” where “gateway” is the IP address of the default gateway. Press <Enter>.
Console(config)#interface vlan 1 Console(config-if)#ip address 192.168.1.5 255.255.255.0 Console(config-if)#exit Console(config)#ip default-gateway 192.168.1.254 Console(config)#
Dynamic Configuration
If you select the “bootp” or “dhcp” option, IP will be enabled but will not function until a BOOTP or DHCP reply has been received. You therefore need to use the “ip dhcp restart” command to start broadcasting service requests. Requests will be sent periodically in an effort to obtain IP configuration information. (BOOTP and DHCP values can include the IP address, subnet mask, and default gateway.)
1-8
B
ASIC CONFIGURATION
If the “bootp” or “dhcp” option is saved to the startup-config file (step 6), then the switch will start broadcasting service requests as soon as it is powered on.
To automatically configure the switch by communicating with BOOTP or DHCP address allocation servers on the network, complete the following steps:
1. From the Global Configuration mode prompt, type “interface vlan 1” to access the interface-configuration mode. Press <Enter>.
2. At the interface-configuration mode prompt, use one of the following commands:
To obtain IP settings via DHCP, type “ip address dhcp” and press <Enter>.
To obtain IP settings via BOOTP, type “ip address bootp” and press <Enter>.
3. Type “end” to return to the Privileged Exec mode. Press <Enter>.
4. Type “ip dhcp restart” to begin broadcasting service requests. Press <Enter>.
5. Wait a few minutes, and then check the IP configuration settings by typing the “show ip interface” command. Press <Enter>.

Enabling SNMP Management Access

The switch can be configured to accept management commands from Simple Network Management Protocol (SNMP) applications. You can configure the switch to (1) respond to SNMP requests or (2) generate SNMP traps.
When SNMP management stations send requests to the switch (either to return information or to set a parameter), the switch provides the requested data or sets the specified parameter. The switch can also be configured to send information to SNMP managers (without being requested by the managers) through trap messages, which inform the manager that certain events have occurred.
Community Strings
Community strings are used to control management access to SNMP stations, as well as to authorize SNMP stations to receive trap messages from the switch. You therefore need to assign community strings to specified users or user groups, and set the access level.
1-10
B
ASIC CONFIGURATION
The default strings are:
public - with read-only access. Authorized management stations are only able to retrieve MIB objects.
private - with read-write access. Authorized management stations are able to both retrieve and modify MIB objects.
Note: If you do not intend to utilize SNMP, it is recommended
that you delete both of the default community strings. If there are no community strings, then SNMP management access to the switch is disabled.
To prevent unauthorized access to the switch via SNMP, it is recommended that you change the default community strings.
To configure a community string, complete the following steps:
1. From the Privileged Exec level global configuration mode
prompt, type “snmp-server community string mode,” where “string” is the community access string and “mode” is rw (read/write) or ro (read only). Press <Enter>.
2. To remove an existing string, simply type “no snmp-server
community string,” where “string” is the community access string to remove. Press <Enter>.
Console(config)#snmp-server community abc rw Console(config)#snmp-server community private Console(config)#

WITCH MANAGEMENT
Trap Receivers
You can also specify SNMP stations that are to receive traps from the switch.
To configure a trap receiver, complete the following steps:
1. From the Privileged Exec level global configuration mode prompt, type “snmp-server host host-address community-string,” where “host-address” is the IP address for the trap receiver and “community-string” is the string associated with that host. Press <Enter>.
2. In order to configure the switch to send SNMP notifications, you must enter at least one snmp-server enable traps command. Type “snmp-server enable traps type,” where “type” is either authentication or link-up-down. Press <Enter>.
Console(config)#snmp-server enable traps link-up-down Console(config)#

Saving Configuration Settings

Configuration commands only modify the running configuration file and are not saved when the switch is rebooted. To save all your configuration changes in nonvolatile storage, you must copy the running configuration file to the start-up configuration file using the “copy” command.
To save the current configuration settings, enter the following command:
1. From the Privileged Exec mode prompt, type “copy running-config startup-config” and press <Enter>.

Managing System Files

The switch’s flash memory supports three types of system files that can be managed by the CLI program, Web interface, or SNMP. The switch’s file system allows files to be uploaded and downloaded, copied, deleted, and set as a start-up file.
The three types of files are:
Configuration — This file stores system configuration information and is created when configuration settings are saved. Saved configuration files can be selected as a system start-up file or can be uploaded via TFTP to a server for backup. A file named “Factory_Default_Config.cfg” contains all the system default settings and cannot be deleted from the system. See “Saving or Restoring Configuration Settings” on page 2-22 for more information.
Operation Code — System software that is executed after boot-up, also known as run-time code. This code runs the switch operation and provides the CLI and Web management interfaces. See “Managing Firmware” on page 2-20 for more information.
Diagnostic Code — Software that is run during system boot-up, also known as POST (Power On Self-Test). This code
1-13
S
WITCH MANAGEMENT
also provides a facility to upload firmware files to the system directly through the console port. See “Upgrading Firmware via the Serial Port” on page B-1.
Due to the size limit of the flash memory, the switch supports only one operation code file, and two diagnostic code files. However, you can have as many configuration files as available flash memory space allows.
In the system flash memory, one file of each type must be set as the start-up file. During a system boot, the diagnostic and operation code files set as the start-up file are run, and then the start-up configuration file is loaded. Configuration files can also be loaded while the system is running; however, this will automatically reboot the switch.

System Defaults

The switch’s system defaults are provided in the configuration file “Factory_Default_Config.cfg.” To reset the switch defaults, this file should be set as the startup configuration file (page 2-22).

Using the Web Interface

This switch provides an embedded HTTP Web agent. Using a Web browser you can configure the switch and view statistics to monitor network activity. The Web agent can be accessed by any computer on the network using a standard Web browser (Internet Explorer 5.0 or above, or Netscape Navigator 6.2 or above).
Note: You can also use the Command Line Interface (CLI) to
manage the switch over a serial connection to the console port or via Telnet. For more information on using the CLI, refer to “Using the Command Line Interface.”
Prior to accessing the switch from a Web browser, first perform the following tasks:
1. Configure the switch with a valid IP address, subnet mask, and
default gateway using an out-of-band serial connection, BOOTP or DHCP protocol. (See “Setting the IP Address” on page 2-11.)
2
2. Set user names and passwords using an out-of-band serial
connection. Access to the Web agent is controlled by the same user names and passwords as the onboard configuration program. (See “Configuring the Logon Password” on page 2-15.)
3. After you enter a user name and password, you will have
access to the system configuration program.
2-1
C
ONFIGURING THE SWITCH
Notes: 1. You are allowed three attempts to enter the correct
password; on the third failed attempt the current connection is terminated.
2. If you log into the Web interface as guest (Normal Exec level), you can view page information but only change the guest password. If you log in as “admin” (Privileged Exec level), you can apply changes on all pages.
3. If the path between your management station and this switch does not pass through any device that uses the Spanning Tree Algorithm, you can set the switch port attached to your management station to fast forwarding to improve the switch’s response time to management commands issued through the Web interface. See “Managing STA Interface Settings” on page 2-47.

Navigating the Web Browser Interface

To access the Web-browser interface you must first enter a user name and password. The administrator has Read/Write access to all configuration parameters and statistics. The default user name and password for the administrator is “admin.”

Standalone Switch

Setting the IP Address

The IP address for this switch is unassigned by default. To manually configure an address, you need to change the switch’s default settings (IP address 0.0.0.0 and netmask 255.0.0.0) to values that are compatible with your network. You may also need to a establish a default gateway between the switch and management stations that exist on another network segment.
You can manually configure a specific IP address, or direct the device to obtain an address from a BOOTP or DHCP server. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods. Anything outside this format will not be accepted by the configuration program.
2-11
C
ONFIGURING THE SWITCH
Command Attributes
Management VLAN – This is the only VLAN through which you can manage the switch. By default, all ports on the switch are members of VLAN 1, so a management station can be connected to any port on the switch. However, if you change the Management VLAN to another VLAN, you will lose access to the switch unless the management port has already been configured as a member of the new VLAN. If you lose access, you can reconnect the management station to a port that is a member of the Management VLAN or use the console interface to add the management port to the newly configured Management VLAN. (See “switchport allowed vlan” on page 129.)
IP Address Mode – Specifies whether IP functionality is enabled via manual configuration (Static), Dynamic Host Configuration Protocol (DHCP), or Boot Protocol (BOOTP). If DHCP/BOOTP is enabled, IP will not function until a reply has been received from the server. Requests will be broadcast periodically by the switch for IP configuration settings. (DHCP/ BOOTP values can include the IP address, subnet mask, and default gateway.)
IP Address – Address of the VLAN interface that is allowed management access. Valid IP addresses consist of four numbers, 0 to 255, separated by periods. (Default: 0.0.0.0)
Subnet Mask – This mask identifies the host address bits used for routing to specific subnets. (Default: 255.0.0.0)
Gateway IP Address – IP address of the gateway router between this device and management stations that exist on other network segments. (Default: 0.0.0.0)
MAC Address – The physical layer address for this switch.

ONFIGURING USER AUTHENTICATION
Renewing DCHP – DHCP may lease addresses to clients indefinitely or for a specific period of time. If the address expires or the switch is moved to another network segment, you will lose management access to the switch. In this case, you can reboot the switch or submit a client request to restart DHCP service.
Web – If the address assigned by DHCP is no longer functioning, you will not be able to renew the IP settings via the Web interface. You can only restart DHCP service via the Web interface if the current address is still available.
CLI – Enter the following command to restart DHCP service.
Console#ip dhcp restart 3-81

Configuring User Authentication

Use the Passwords or Radius menu to restrict management access based on specified user names and passwords. You can manually configure access rights on the switch (Passwords menu), or you can use a remote access authentication server based on the RADIUS protocol (Radius menu).

Configuring the Logon Password

The guest only has read access for most configuration parameters. However, the administrator has write access for all parameters governing the onboard agent. You should therefore assign a new administrator password as soon as possible, and store it in a safe place. (If for some reason your password is lost, you can reload the factory default settings to restore the default password as described in “Upgrading Firmware via the Serial Port” on page B-1.)

ONFIGURING USER AUTHENTICATION

Configuring RADIUS Logon Authentication

Remote Authentication Dial-in User Service (RADIUS) is a logon authentication protocol that uses software running on a central server to control access to RADIUS-compliant devices on the network. An authentication server contains a database of multiple user name/password pairs with associated privilege levels for each user or group that require management access to a switch.
Command Usage
By default, management access is always checked against the authentication database stored on the local switch. If a remote authentication server is used, you must specify the authentication sequence and the corresponding parameters for the remote authentication protocol.
RADIUS uses UDP, which only offers best-effort delivery. Also, RADIUS encrypts only the password in the access-request packet from the client to the server.
RADIUS logon authentication assigns a specific privilege level for each user name/password pair. The user name, password, and privilege level must be configured on the authentication server.
You can specify one to two authentication methods for any user to indicate the authentication sequence. For example, if you select (1) RADIUS and (2) Local, the user name and password on the RADIUS server is verified first. If the RADIUS server is not available, then the local user name and password is checked.

Server Port Number – Network (UDP) port of authentication server used for authentication messages. (Range: 1-65535; Default: 1812)
Secret Text String – Encryption key used to authenticate logon access for client. Do not use blank spaces in the string. (Maximum length: 20 characters)
Number of Server Transmits – Number of times the switch will try to authenticate logon access via the authentication server. (Range: 1-30; Default: 2)
Timeout for a reply – The number of seconds the switch waits for a reply from the RADIUS server before it resends the request. (Range: 1-65535; Default: 5)

- Sym (Gigabit only) - Check this item to transmit and receive pause frames, or clear it to auto-negotiate the sender and receiver for asymmetric pause frames. (The current switch chip only supports symmetric pause frames.)
- FC - Supports flow control
- Flow control can eliminate frame loss by “blocking” traffic from end stations or segments connected directly to the switch when its buffers fill. When enabled, back pressure is used for half-duplex operation and IEEE 802.3x for full-duplex operation. (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.)
Trunk – Indicates if a port is a member of a trunk. To create trunks and select port members, see “Port Trunk Configuration” on page 2-79.
*Auto-negotiation must be disabled before you can configure or force the
interface to use the Speed/Duplex Mode or Flow Control options.

Configuring Port Mirroring

You can mirror traffic from any source port to a target port for real-time analysis. You can then attach a logic analyzer or RMON probe to the target port and study the traffic crossing the source port in a completely unobtrusive manner.
Command Usage
Monitor port speed should match or exceed source port speed, otherwise traffic may be dropped from the monitor port.
All mirror sessions have to share the same destination port.
When mirroring port traffic, the target port must be included in the same VLAN as the source port.
The switch can only mirror one port at a time.
Command Attributes
Mirror Sessions – Displays a list of current mirror sessions.
Source Port – The port whose traffic will be monitored.
Type – Allows you to select which traffic to mirror to the target port, Rx (receive), Tx (transmit), or Both.
Target Port – The port that will “duplicate” or “mirror” the traffic on the source port.

Spanning Tree Algorithm Configuration

The Spanning Tree Algorithm (STA) can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the switch to interact with other bridging devices (that is, an STA-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.
STA uses a distributed algorithm to select a bridging device (STA-compliant switch, bridge or router) that serves as the root of the spanning tree network. It selects a root port on each bridging
2-42
S
PANNING TREE ALGORITHM CONFIGURATION
device (except for the root device) which incurs the lowest path cost when forwarding a packet from that device to the root device. Then it selects a designated bridging device from each LAN which incurs the lowest path cost when forwarding a packet from that LAN to the root device. All ports connected to designated bridging devices are assigned as designated ports. After determining the lowest cost spanning tree, it enables all root ports and designated ports, and disables all other ports. Network packets are therefore only forwarded between root ports and designated ports, eliminating any possible network loops.

Managing Global Settings

Global settings apply to the entire switch.
Command Attributes
The following global attributes are fixed and cannot be changed:
Bridge ID – The priority and MAC address of this device.
Designated Root – The priority and MAC address of the device in the Spanning Tree that this switch has accepted as the root device.
Root Port – The number of the port on this switch that is closest to the root. This switch communicates with the root device through this port. If there is no root port, has been accepted as the root device of the Spanning Tree network.
Root Path Cost – The path cost from the root port on this switch to the root device.

The following global attributes can be configured:
Spanning Tree State – Enables/disables this switch to participate in a STA-compliant network.
Priority – Bridge priority is used in selecting the root device, root port, and designated port. The device with the highest priority becomes the STA root device. However, if all devices have the same priority, the device with the lowest MAC address will then become the root device. (Note that lower numeric values indicate higher priority.)

Hello Time – Interval (in seconds) at which the root device transmits a configuration message.
- Default: 2
- Minimum: 1
- Maximum: The lower of 10 or [(Max. Message Age / 2) -1]
Maximum Age – The maximum time (in seconds) a device can wait without receiving a configuration message before attempting to reconfigure. All device ports (except for designated ports) should receive configuration messages at regular intervals. Any port that ages out STA information (provided in the last configuration message) becomes the designated port for the attached LAN. If it is a root port, a new root port is selected from among the device ports attached to

- Default: 20
- Minimum: The higher of 6 or [2 x (Hello Time + 1)].
- Maximum: The lower of 40 or [2 x (Forward Delay - 1)]
Forward Delay – The maximum time (in seconds) the root device will wait before changing states (i.e., listening to learning to forwarding). This delay is required because every device 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.

Command Attributes
The following attributes are read-only and cannot be changed:
Port Status – Displays current state of this port within the Spanning Tree:
- Disabled - The port has been disabled by the user or has failed diagnostics.
- Blocking - Port receives STA configuration messages, but does not forward packets.
- Listening - Port will leave blocking state due to a topology change, start transmitting configuration messages, but does not yet forward packets.
- Learning - Port has transmitted configuration messages for an interval set by the Forward Delay parameter without receiving contradictory information. Port address table is cleared, and the port begins learning addresses.
- Forwarding - Port forwards packets, and continues learning addresses.
- Broken - Port is malfunctioning or no link has been established.
The rules defining port status are:
A port on a network segment with no other STA compliant bridging device is always forwarding.
If two ports of a switch are connected to the same segment and there is no other STA device attached to this segment, the port with the smaller ID forwards packets and the other is blocked.
All ports are blocked when the switch is booted, then some of them change state to listening, to learning, and then to forwarding.
Forward Transitions – The number of times this port has transitioned from the Learning state to the Forwarding state.
2-48

PANNING TREE ALGORITHM CONFIGURATION
Designated Cost – The cost for a packet to travel from this port to the root in the current Spanning Tree configuration. The slower the media, the higher the cost.
Designated Bridge – The priority and MAC address of the device through which this port must communicate to reach the root of the Spanning Tree.
Designated Port – The priority and number of the port on the designated bridging device through which this switch must communicate with the root of the Spanning Tree.
Trunk Member – Indicates if a port is a member of a trunk. (STA Port Information only)
The following interface attributes can be configured:
Priority – Defines the priority used for this port in the Spanning Tree Protocol. If the path cost for all ports on a switch are the same, the port with the highest priority (i.e., lowest value) will be configured as an active link in the Spanning Tree. This makes a port with higher priority less likely to be blocked if the Spanning Tree Protocol is detecting network loops. Where more than one port is assigned the highest priority, the port with lowest numeric identifier will be enabled.
- Default: 128
- Range: 0 - 255

C
ONFIGURING THE SWITCH
Path Cost – This parameter is used by the STP to determine the best path between devices. Therefore, lower values should be assigned to ports attached to faster media, and higher values assigned to ports with slower media. (Path cost takes precedence over port priority.)

- Recommended Range –

- Gigabit Ethernet – full duplex: 4; trunk: 3
Fast Forwarding – You can enable this option if an interface is attached to a LAN segment that is at the end of a bridged LAN or to an end node. Since end-nodes cannot cause forwarding loops, they can pass directly through to the forwarding state. Fast Forwarding can achieve quicker convergence for end-node workstations and servers, and also overcome other STA related timeout problems. (Remember that Fast Forwarding should only be enabled for ports connected to an end-node device.)

VLAN Configuration

In conventional networks with routers, broadcast traffic is split up into separate domains. Switches do not inherently support broadcast domains. This can lead to broadcast storms in large networks that handle traffic such as IPX or NetBeui. By using IEEE
802.1Q-compliant VLANs, you can organize any group of network nodes into separate broadcast domains, thus confining broadcast traffic to the originating group. This also provides a more secure and cleaner network environment.
An IEEE 802.1Q VLAN is a group of ports that can be located anywhere in the network, but communicate as though they belong to the same physical segment.
2-52
VLAN C
VLANs help to simplify network management by allowing you to move devices to a new VLAN without having to change any physical connections. VLANs can be easily organized to reflect departmental groups (such as Marketing or R&D), usage groups (such as e-mail), or multicast groups (used for multimedia applications such as videoconferencing).
VLANs provide greater network efficiency by reducing broadcast traffic, and allow you to make network changes without having to update IP addresses or IP subnets. VLANs inherently provide a high level of network security since traffic must pass through a configured Layer 3 link to reach a different VLAN.
This switch supports the following VLAN features:
Up to 127 VLANs based on the IEEE 802.1Q standard
Distributed VLAN learning across multiple switches using explicit or implicit tagging and GVRP protocol
Port overlapping, allowing a port to participate in multiple VLANs
ONFIGURATION
End stations can belong to multiple VLANs
Passing traffic between VLAN-aware and VLAN-unaware devices
Priority tagging
Assigning Ports to VLANs
Before enabling VLANs for the switch, you must first assign each port to the VLAN group(s) in which it will participate. By default all ports are assigned to VLAN 1 as untagged ports. Add a port as a tagged port if you want it to carry traffic for one or more VLANs, and any intermediate network devices or the host at the other end of the connection supports VLANs. Then assign ports on the other VLAN-aware network devices along the path that will carry this
2-53
C
ONFIGURING THE SWITCH
traffic to the same VLAN(s), either manually or dynamically using GVRP. However, if you want a port on this switch to participate in one or more VLANs, but none of the intermediate network devices nor the host at the other end of the connection supports VLANs, then you should add this port to the VLAN as an untagged port.
Note: VLAN-tagged frames can pass through VLAN-aware or
VLAN-unaware network interconnection devices, but should not be used for any end-node host that does not support VLAN tagging.
VLAN Classification – When the switch receives a frame, it classifies the frame in one of two ways. If the frame is untagged, the switch assigns the frame to an associated VLAN (based on the PVID of the receiving port). But if the frame is tagged, the switch uses the tagged VLAN ID to identify the port broadcast domain of the frame.
Port Overlapping – Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as file servers or printers. Note that if you implement VLANs which do not overlap, but still need to communicate, you can connect them by using a Layer-3 router or switch.
Untagged VLANs – Untagged (or static) VLANs are typically used to reduce broadcast traffic and to increase security. A group of network users assigned to a VLAN form a broadcast domain that is separate from other VLANs configured on the switch. Packets are forwarded only between ports that are designated for the same VLAN. Untagged VLANs can be used to manually isolate user groups or subnets. However, you should use IEEE 802.3 tagged VLANs with GVRP whenever possible to fully automate VLAN registration.
2-54
VLAN C
Automatic VLAN Registration – GVRP (GARP VLAN Registration Protocol) defines a system whereby the switch can automatically learn the VLANs to which each endstation should be assigned. If an endstation (or its network adapter) supports the IEEE 802.1Q VLAN protocol, it can be configured to broadcast a message to your network indicating the VLAN groups it wants to join. When this switch receives these messages, it will automatically place the receiving port in the specified VLANs, and then forward the message to all other ports. When the message arrives at another switch that supports GVRP, it will also place the receiving port in the specified VLANs, and pass the message on to all other ports. VLAN requirements are propagated in this way throughout the network. This allows GVRP-compliant devices to be automatically configured for VLAN groups based solely on endstation requests.
To implement GVRP in a network, first add the host devices to the required VLANs (using the operating system or other application software), so that these VLANs can be propagated onto the network. For both the edge switches attached directly to these hosts, and core switches in the network, enable GVRP on the links between these devices. You should also determine security boundaries in the network and disable GVRP on ports to prevent advertisements being propagated, or forbid ports from joining restricted VLANs.
ONFIGURATION
Note: If you have host devices that do not support GVRP, you
must configure static VLANs for the switch ports connected to these devices (as described in “Adding Static Members to VLANs (VLAN Index)” on page 2-61). But you still need to enable GVRP on these edge switches, as well as on the core switches in the network.
2-55
C
ONFIGURING THE SWITCH
Forwarding Tagged/Untagged Frames
If you want to create a small port-based VLAN for devices attached directly to a single switch, you can assign ports to the same untagged VLAN. However, to participate in a VLAN group that crosses several switches, you need to create a VLAN for that group and enable tagging on all ports.
Ports can be assigned to multiple tagged or untagged VLANs. Each port on the switch is therefore capable of passing tagged or untagged frames. When forwarding a frame from this switch along a path that contains any VLAN-aware devices, the switch should include VLAN tags. When forwarding a frame from this switch along a path that does not contain any VLAN-aware devices (including the destination host), the switch must first strip off the VLAN tag before forwarding the frame. When the switch receives a tagged frame, it will pass this frame onto the VLAN(s) indicated by the frame tag. However, when this switch receives an untagged frame from a VLAN-unaware device, it first decides where to forward the frame, and then inserts a VLAN tag reflecting the ingress port’s default VID.

Adding Static Members to VLANs (Port Index)

Use the VLAN Static Membership by Port menu to assign VLAN groups to the selected interface add an interface to the selected VLAN as a tagged member.
Command Attributes
Interface – Port or trunk identifier.
Member – VLANs for which the selected interface is a tagged member.
Non-Member – VLANs for which the selected interface is not a member.
Web – Click VLAN, VLAN Static Membership by Port. Select an interface from the scroll-down box (Port or Trunk). Click Query to display membership information for the interface. Select a VLAN ID, and then click Add to add the interface as a tagged member, or click Remove to remove the interface. After configuring VLAN membership for each interface, click Apply.

CLI – This example adds Port 3 to VLAN 1 as a tagged port.
Console(config)#interface ethernet 1/3 3-89 Console(config-if)#switchport allowed vlan add 1 tagged 3-129

Configuring VLAN Behavior for Interfaces

You can configure VLAN behavior for specific interfaces, including the default VLAN identifier (PVID), accepted frame types, ingress filtering, GVRP status, and GARP timers.
Command Usage
GVRP – GARP VLAN Registration Protocol defines a way for switches to exchange VLAN information in order to automatically register VLAN members on interfaces across the network.
GARP – Group Address Registration Protocol is used by GVRP to register or deregister client attributes for client services within a bridged LAN. The default values for the GARP timers are independent of the media access method or data rate. These values should not be changed unless you are experiencing difficulties with GVRP registration/deregistration.
ONFIGURATION
Command Attributes
Ingress Filtering – If ingress filtering is enabled, incoming frames for VLANs which do not include this ingress port in their member set will be discarded at the ingress port. (Default: Disabled)
- Ingress filtering only affects tagged frames.
- If ingress filtering is disabled, the interface will accept any VLAN-tagged frame if the tag matches a VLAN known to the switch (except for those VLANs explicitly forbidden on this port).

ONFIGURING THE SWITCH
- If ingress filtering is enabled, the interface will discard incoming frames tagged for VLANs which do not include this ingress port in their member set.
-
Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP dependent BPDU frames, such as GMRP.
or STP. However, it does affect VLAN
PVID – interface. (Default: 1)
- If an interface is not a member of VLAN 1 and you assign its
Acceptable Frame Type – Sets the interface to accept all frame types, including tagged or untagged frames, or only tagged frames. When set to receive all frame types, any received frames that are untagged are assigned to the default VLAN. (Option: All, Tagged; Default: All)
- This field is read-only for the Web, and read/write for the CLI
GVRP Status – Enables/disables GVRP for the interface. GVRP must be globally enabled for the switch before this setting can take effect. (See “Displaying Bridge Extension Capabilities” on page 2-24.) When disabled, any GVRP packets received on this port will be discarded and no GVRP registrations will be propagated from other ports. (Default: Disabled)
- GVRP can only be enabled for tagged ports.
- You must set Mode to 1Q Trunk to configure a tagged port.
VLAN ID assigned to untagged frames received on the
PVID to this VLAN, the interface will automatically be added to VLAN 1 as an untagged member. For all other VLANs, an interface must first be configured as an untagged member before you can assign its PVID to that group.
(page 3-126).
GARP Join Timer* – The interval between transmitting requests/queries to participate in a VLAN group. (Range: 20-1000 centiseconds; Default: 20)
2-66
VLAN C
ONFIGURATION
GARP Leave Timer* – The interval a port waits before leaving a VLAN group. This time should be set to more than twice the join time. This ensures that after a Leave or LeaveAll message has been issued, the applicants can rejoin before the port actually leaves the group. (Range: 60-3000 centiseconds; Default: 60)
GARP LeaveAll Timer* – The interval between sending out a LeaveAll query message for VLAN group participants and the port leaving the group. This interval should be considerably larger than the Leave Time to minimize the amount of traffic generated by nodes rejoining the group. (Range: 500-18000 centiseconds; Default: 1000)
*Timer settings must follow this rule:
2 x (join timer) < leave timer < leaveAll timer
Trunk Member – Indicates if a port is a member of a trunk. To add a trunk to the selected VLAN, use the last table on the VLAN Static Table page.
Mode – Indicates VLAN membership egress mode for an interface. (Default: Access)
- Access – Sets the port to operate as an untagged interface. All frames are sent untagged.
- 1Q Trunk – Specifies a port as an end-point for a VLAN trunk. A trunk is a direct link between two switches, so the port transmits tagged frames that identify the source VLAN. However, note that frames belonging to the port’s default VLAN (i.e., associated with the PVID) are sent untagged.

Configuring Private VLANs

Private VLANs provide port-based security and isolation between ports within the assigned VLAN. This switch supports two types of private VLAN ports: promiscuous, and community ports. A promiscuous port can communicate with all interfaces within a private VLAN. Community ports can only communicate with other
