Configuring Remote AP Failback
In conjunction with the backup controller list, you can configure remote APs to revert back (failback) to the primary
controller if it becomes available. If you do not explicitly configure this behavior, the remote AP will keep its
connection with the backup controller until the remote AP, controller, or both have rebooted or some type of
network failure occurs. If any of these events occur, the remote AP will go through the backup controller list and
attempt to connect with the primary controller.
