Usage Guidelines
Use this command to set parameters for VRRP on the controller. The default VRRP parameters can be left for
most implementations.
You can use a combination of numbers, letters, and characters to create the authentication password and the
VRRP description. To include a space in the password or description, enter quotation marks around the string.
For example, to create the password Floor 1, enter “Floor 1” at the prompt.
To change the existing password or description, enter the command with a different string. The new password
or description takes affect immediately.
To unconfigure the existing password or description, enter ““ at the prompt. If you update the password on
one controller, you must update the password on the redundant member pair.
Interface Tracking
You can track multiple VRRP instances to prevent asymmetric routing and dynamically change the VRRP master
to adapt to changes in the network. VRRP interface tracking can alter the priority of the VRRP instance based
on the state of a particular VLAN or Layer-2 interface. The priority of the VRRP instance can increase or
decrease based on the operational state of the specified interface. For example, interface transitions (up/down
events) can trigger a recomputation of the VRRP priority, which can change the VRRP master depending on the
resulting priority. You can track a combined maximum of 16 interfaces.
You must enable preempt mode to allow a controller to take over the role of master if it detects a lower priority
controller currently acting as master
Example
The following command configures a priority of 105 for VRRP ID (VRID) 30:
(host) (config) #vrrp 30
priority 105
The following commands configure VLAN interface tracking and assumes the following:
l You have two controllers, a primary and a backup.
l The configuration highlights the parameters for interface tracking. You may have other parameters
configured for VRRP.
