AP Redundancy
In conjunction with the controller redundancy features described in Chapter 20, “VRRP” the information in this
section describes redundancy for APs. Remote APs also offer redundancy solutions via a backup configuration,
backup controller list, and remote AP failback. For more information relevant to remote APs, see Chapter 6,
“Remote Access Points” .
AP failback
The AP failback feature allows an AP associated with the backup controller (backup LMS) to fail back to the
primary controller (primary LMS) if it becomes available.
To configure this feature you must:
z Configure the LMS IP address
z Configure the backup LMS IP address
z Enable LMS preemption
z Configure the LMS hold-down timer
If configured, the AP monitors the primary controller by sending probes every 600 seconds by default. If the AP
successfully contacts the primary controller for the entire hold-down period, it will fail back to the primary
controller. If the AP is unsuccessful, the AP maintains its connection to the backup controller, restarts the LMS
hold-down timer, and continues monitoring the primary controller.
The following example assumes:
z You have not configured the LMS or backup LMS IP addresses
z Default values unless otherwise noted.
