occurs.
VRRP ID [1-255]
For each primary controller in the redundancy group, enter a number from
1 through 255 as the VRRP ID. This enables each primary controller to have a
unique relationship with the redundant controller.
1 through 255 as the VRRP ID. This enables each primary controller to have a
unique relationship with the redundant controller.
Note:
For a single controller with redundancy, there is a single primary
controller and therefore a single VRRP ID.
Local IP
For each primary controller in the redundancy group, enter a local IP address.
This IP address remains assigned to the primary controller and is not
transferred to the redundant controller if a failover occurs. This allows each
primary controller to be identified before and after a failover.

Note:
For a single controller with redundancy, there is a single primary
