5. 
Configure the VRRP IDs and local IP addresses of the controllers in the stack so they can 
become part of the redundancy group. The settings, including the nonconfigurable fields, are 
explained in the following table:
WARNING!
Enabling redundancy causes the wireless controller to reboot, 
which might temporarily affect traffic on the managed access 
points in the network.

Description
Controller Role
This is a nonconfigurable field that shows if the primary controller functions as a 
master or slave controller in the stack for which you are configuring 
redundancy.
Note: 
For a single controller with redundancy, the primary controller role is 
always master.
Controller IP
This is a nonconfigurable field that shows the IP address of the primary 
controller. This IP address is transferred to the redundant controller if a failover 
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. 
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 
controller for which you need to enter a local IP address.
