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
