Implementing Redundancy
There are three options available for controller redundancy:
 Redundant Ethernet: With this Ethernet link level redundancy, if one Ethernet
link goes down, another Ethernet link on the same controller will take over.
 N+1: With this controller level redundancy, if one controller goes down, a
designated slave controller will take over for the failed master controller.
 Option 43: With this controller level redundancy, an AP is aware of both the
primary and secondary controller. If the primary controller goes down, the APs
automatically associate with the secondary controller. If the primary controller
comes back up, they associate to the primary controller.
