aremaxhop hop_count

(Optional) Keyword to specify the maximum number of hops for All-Routes Explorer frames. Possible values are 1 to 13; the default is 7. This parameter is only valid when defining or configuring TrCRFs.

stemaxhop hop_count

(Optional) Keyword to specify the maximum number of hops for Spanning-Tree Explorer frames. Possible values are 1 to 13; the default is 7. This parameter is only valid when defining or configuring TrCRFs.


Default

The default configuration has all switched Ethernet ports and Ethernet repeater ports in VLAN 1. The default SAID is 100001 for VLAN 1, 100002 for VLAN 2, 100003 for VLAN 3, and so on. The default type is Ethernet. The default MTU is 1500 bytes. The default state is active.

The default TrBRF is 1005, the default TrCRF is 1003, and the default MTU for TrBRFs and TrCRFs is 4472. The default state is active.

Command Type

Switch command.

Command Mode

Privileged.

Usage Guidelines

You cannot use the set vlan command until the Catalyst 5000, 4000, 2926G, and 2926 series switches are is either in VTP transparent mode (set vtp mode transparent) or until a VTP domain name has been set (set vtp domain name).

Valid MTU values for Token Ring VLAN are 1500 or 4472. While you can enter any value for the MTU value, the value you enter defaults to the next lowest valid value.

You cannot set multiple VLANs for ISL ports using this command. The VLAN name can be from 1 to 32 characters in length. If adding a new VLAN, the VLAN number must be within the range 2 to 1001. When modifying a VLAN, the valid range for the VLAN number is 2 to 1005.

On a new Token Ring VLAN, if you do not specify the parent parameter for a TrCRF, the default TrBRF (1005) is used.

The Catalyst 4000 and 2948G series switches are Ethernet-only devices.

The Catalyst 2948G is a fixed configuration switch. All ports are located on module 2; for this reason, if you enter 1/N for the module/port number, an error message is displayed.

Example

This example shows how to set VLAN 850 to include ports 3 through 7 on module 3. Ports 3 through 7 were assigned to TrCRF 1003, therefore, the message reflects the modification of VLAN 1003: 

Console> (enable) set vlan 850 3/4-7

VLAN 850 modified.

VLAN 1003 modified.

set vmps server

Use the set vmps server command to configure the IP address of the VMPS server to be queried.

set vmps server ip_addr [primary]

Syntax Description

ip_addr

IP address of the VMPS server.

primary

(Optional) Keyword to identify the specified device as the primary VMPS server.


Default

If no IP address is specified, VMPS uses the local VMPS configuration.

Command Type

Switch command.

Command Mode

Privileged.

Usage Guidelines

This command is not supported by the Catalyst 4000 and 2948G series switches.

You can specify the IP addresses of up to three VMPS servers. You can define any VMPS server as the primary VMPS server.

If the primary VMPS server is down, all subsequent queries go to a secondary VMPS server. VMPS checks on the primary server's availability once every five minutes. When the primary VMPS server comes back online, subsequent VMPS queries are directed back to the primary VMPS server.

To use a co-resident VMPS (when VMPS is enabled in a device), configure one of the three VMPS addresses as the IP address of interface sc0.

Example

This example shows how to define a VMPS server: 

Console> (enable) set vmps server 192.168.10.140 primary

192.168.10.140 added to VMPS table as primary domain server.

Console> (enable) set vmps server 192.168.69.171

192.168.69.171 added to VMPS table as backup domain server.

Console> (enable)

Related Command

set vmps state

Use the set vmps state command to enable or disable VMPS.

set vmps state {enable | disable}

Syntax Description

enable

Keyword to enable VMPS.

disable

Keyword to disable VMPS.


Default

By default, VMPS is disabled.

Command Type

Switch command.

Command Mode

Privileged.

Usage Guidelines

This command is not supported by the Catalyst 4000 and 2948G series switches.

Before using the set vmps state command, you must use the set vmps tftpserver command to specify the IP address of the server from which the VMPS database is downloaded.

Examples

This example shows how to enable VMPS: 

Console> (enable) set vmps state enable

Vlan membership Policy Server enabled.

Console> (enable)

This example shows how to disable VMPS: 

Console> (enable) set vmps state disable

All the VMPS configuration information will be lost and the resources released on 
disable.

Do you want to continue (y/n[n]):y

VLAN Membership Policy Server disabled.

Console> (enable)

set vmps tftpserver

Use the set vmps tftpserver command to specify the TFTP server's IP address of the VMPS downloaded database and the VMPS storage location.

set vmps tftpserver ip_addr [filename]

Syntax Description

ip_addr

IP address of the TFTP server from which the VMPS database is downloaded.

filename

(Optional) VMPS configuration filename on the TFTP server.


Default

If filename is not specified, the set vmps tftpserver command uses the default filename vmps-config-database.1.

Command Type

Switch command.

Command Mode

Privileged.

Usage Guideline

This command is not supported by the Catalyst 4000 and 2948G series switches.

Example

This example shows how to specify the server from which the VMPS database is downloaded and the configuration filename: 

Console> (enable) set vmps tftpserver 192.168.69.100 vmps_config.1

IP address of the TFTP server set to 192.168.69.100

VMPS configuration filename set to vmps_config.1

Console> (enable)

set vtp

Use the set vtp command to set the options for VTP.

set vtp [domain domain_name] [mode {client | server | transparent}] [passwd passwd] [pruning {enable | disable}] [v2 {enable | disable}]

Syntax Description

domain domain_name

(Optional) Keywords to define the name that identifies the VLAN management domain. The domain_name can be 1 to 32 characters in length.

mode {client | server | transparent}

(Optional) Keywords to specify the VTP mode.

passwd passwd

(Optional) Keyword to define the VLAN trunk protocol password. The VTP password can be 8 to 64 characters in length.

pruning {enable | disable}

(Optional) Keywords to enable or disable VTP pruning for the entire management domain.

v2 {enable | disable}

(Optional) Keyword to set version 2 mode.


Default

The defaults are as follows: server mode, no password, pruning disabled, and v2 disabled.

Command Type

Switch command.

Command Mode

Privileged.

Usage Guidelines

All switches in a VTP domain must run the same version of VTP. VTP version 1 and VTP
version 2 do not operate on switches in the same VTP domain. VTP version 2 is supported in software release 3.1(1) and later and is disabled by default.

If all switches in a domain are VTP version 2-capable, you only need to enable VTP version 2 on one switch (using the set vtp v2 enable command); the version number is then propagated to the other version 2-capable switches in the VTP domain.

If the VTP password has already been defined, entering passwd 0 (zero) clears the VTP password.

VTP supports three different modes: server, client, and transparent. If you make a change to the VTP or VLAN configuration on a switch in server mode, that change is propagated to all of the switches in the same VTP domain.

If the receiving switch is in server mode, the configuration is not changed.

If the receiving switch is in client mode, the client switch changes its configuration to duplicate the configuration of the server. If you have switches in client mode, make sure to make all VTP or VLAN configuration changes on a switch in server mode.

If the receiving switch is in transparent mode, the configuration is not changed. Switches in transparent mode do not participate in VTP. If you make VTP or VLAN configuration changes on a switch in transparent mode, the changes are not propagated to the other switches in the network.

If you assign a VTP password, no VTP or VLAN configuration changes can be made without first entering the password.

The pruning keyword is used to enable or disable VTP pruning for the VTP domain. VTP pruning causes information about each pruning-eligible VLAN to be removed from VTP updates if there are no stations belonging to that VLAN out a particular switch port. Use the set vtp pruneeligible and clear vtp pruneeligible commands to specify which VLANs should or should not be pruned when pruning is enabled for the domain.

To disable VTP, enter the set vtp mode transparent command. This disables VTP from the domain but does not remove the domain from the switch. Use the clear config all command to remove the domain from the switch.

Caution   
Be careful when you use the clear config all command. This command clears the entire switch configuration, not just the VTP domain.

Example

This example shows how to use the set vtp command: 

Console> (enable) set vtp domain Engineering mode client

VTP domain Engineering modified

Console> (enable)

Related Commands

set vtp pruneeligible

Use the set vtp pruneeligible command to specify which VLANs in the VTP domain are eligible for pruning.

set vtp pruneeligible vlans

Syntax Description

vlans

Range of VLAN numbers; valid values are 2 to 1000.


Default

By default, VLANs 2 through 1000 are eligible for pruning.

Command Type

Switch command.

Command Mode

Privileged.

Usage Guidelines

VTP pruning causes information about each pruning-eligible VLAN to be removed from VTP updates if there are no stations belonging to that VLAN out a particular switch port. Use the set vtp command to enable VTP pruning.

By default, VLANs 2 through 1000 are pruning eligible. You do not need to use the set vtp pruneeligible command unless you have previously used the clear vtp pruneeligible command to make some VLANs pruning ineligible.

If VLANs have been made pruning ineligible, use the set vtp pruneeligible command to make them pruning eligible again.

Examples

This example shows how to configure pruning eligibility for VLANs 120 and 150: 

Console> (enable) set vtp pruneeligible 120,150

Vlans 120,150 eligible for pruning on this device.

VTP domain nada modified.

Console> (enable)

In this example, VLANs 200-500 were made pruning ineligible using the clear vtp pruneeligible command. This example shows how to make VLANs 220 through 320 pruning eligible again: 

Console> (enable) clear vtp pruneeligible 200-500

Vlans 1,200-500,1001-1005 will not be pruned on this device.

VTP domain Company modified.

Console> (enable)

Console> (enable) set vtp pruneeligible 220-320

Vlans 2-199,220-320,501-1000 eligible for pruning on this device.

VTP domain Company modified.
