 The wireless controller supports N:1 redundancy with failover 

 . 

Redundancy is implemented through the use of the Virtual Router Redundancy Protocol 
(VRRP). 

With N:1 redundancy, you can add one redundant controller for up to three controllers, that is, 
a redundancy group can consist of four controllers, one of which is a redundant controller.

In an N:1 redundancy group with three primary controllers and one redundant controller, you 
could consider the redundant controller to consist of three virtual controllers, each of which 
has a redundancy relationship with a primary controller. You need a unique VRRP ID for 
each relationship.

Each controller in the redundancy group has a unique controller IP address and a unique 
local IP address. Local addresses remain constant so a controller can always be identified 
before and after a failover. If the primary controller fails or is disconnected from the network, 
an automatic failover to the redundant controller occurs. The redundant controller then takes 
ownership of the controller IP address of the primary controller and takes over all functions of 
the primary controller.

After a failover has occurred, there is no longer any redundancy available for the other 

primary controllers in the redundancy group.

VRRP ID [1-255]

For the primary controller, enter a number from 1 through 255 as the VRRP ID. 

Local IP

For the primary controller, enter a local IP address. If a failover occurs, this IP 
address remains assigned to the primary controller and does not transfer to the 
redundant controller to let you identify the primary controller before and after 
the failover.
