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:
Table 38. Redundancy settings
Setting
Controller Role
Controller IP
VRRP ID [1-255]
Local IP
WARNING!
Enabling redundancy causes the wireless controller to reboot,
which might temporarily affect traffic on the managed access
points in the network.

Description
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.
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.
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.
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.
