Configuring basic VSRP parameters

To configure VSRP, perform the following required tasks:

• Configure a port-based VLAN containing the ports for which you want to provide VSRP service.

NOTE
If you already have a port-based VLAN but only want to use VSRP on a sub-set of the VLANs ports,
you can selectively remove ports from VSRP service in the VLAN. Refer to

Removing a port from the

VRID VLAN

on page 107.

• Configure a VRID:

Specify that the device is a backup. Since VSRP, like VRRP-E, does not have an "owner",
all VSRP devices are backups. The active device for a VRID is elected based on the VRID
priority, which is configurable.

Activate the VRID.

The following example shows a simple VSRP configuration.

device(config)#vlan 200

device(config-vlan-200)#tag ethernet 1/1 to 1/8

device(config-vlan-200)#vsrp vrid 1

device(config-vlan-200-vrid-1)#backup

device(config-vlan-200-vrid-1)#activate

Syntax: [no] vsrp vrid num

The num parameter specifies the VRID and can be from 1 - 255.

Syntax: [no] backup [ priority value ] [ track-priority value ]

This command is required. In VSRP, all devices on which a VRID are configured are Backups. The
Master is then elected based on the VSRP priority of each device. There is no "owner" device as there
is in VRRP.

For information about the command optional parameters, refer to the following:

Changing the backup priority

on page 108

Changing the default track priority setting

on page 110

Syntax: [no] activate

or

Syntax: enable | disable

Configuring optional VSRP parameters

The following sections describe how to configure optional VSRP parameters.

Disabling or re-enabling VSRP

VSRP is enabled by default on Layer 2 Switches and Layer 3 Switches. On a Layer 3 Switch, if you
want to use VRRP or VRRP-E for Layer 3 redundancy instead of VSRP, you need to disable VSRP
first. To do so, enter the following command at the global CONFIG level.

device(config)#no router vsrp

router vsrp is disabled. All vsrp config data will be lost when writing to flash
