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.
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
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.
