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.
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:
 You have two controllers, a primary and a backup.
 The configuration highlights the parameters for interface tracking. You may have other parameters configured
for VRRP.
If VLAN 20 goes down, VRRP 20 automatically fails over, VRRP 10 and VRRP 30 would drop their priority to 95,
causing a failover to the backup controller. Once VLAN 20 comes back up, the primary controller restores the
VRRP priority to 105 for all VRRP IDs and resumes the master VRRP role.
Note: 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
