Using the CLI to Configure Backup Controllers

Using the controller CLI, follow these steps to configure primary, secondary, and tertiary controllers for a specific access point and to configure primary and secondary backup controllers for all access points.

Step 1 To configure a primary controller for a specific access point, enter this command:

config ap primary-basecontroller_name Cisco_AP [controller_ip_address]

Note The controller_ip_address parameter in this command and the next two commands is optional. If the backup controller is outside the mobility group to which the access point is connected (the primary controller), then you need to provide the IP address of the primary, secondary, or tertiary controller, respectively. In each command, the controller_name and controller_ip_address must belong to the same primary, secondary, or tertiary controller. Otherwise, the access point cannot join the backup controller.

Step 2 To configure a secondary controller for a specific access point, enter this command:

config ap secondary-basecontroller_name Cisco_AP [controller_ip_address]

Step 3 To configure a tertiary controller for a specific access point, enter this command:

config ap tertiary-basecontroller_name Cisco_AP [controller_ip_address]

Step 4 To configure a primary backup controller for all access points, enter this command:

config advanced backup-controller primary backup_controller_name backup_controller_ip_address

Step 5 To configure a secondary backup controller for all access points, enter this command:

config advanced backup-controller secondary backup_controller_name backup_controller_ip_address

Note To delete a primary or secondary backup controller entry, enter 0.0.0.0 for the controller IP address.

Step 6 To enable or disable the fast heartbeat timer for local or hybrid-REAP access points, enter this command:

config advanced timers ap-fast-heartbeat {local hreap all} {enable disable} interval

where all is both local and hybrid-REAP access points, and interval is a value between 1 and 10 seconds (inclusive). Specifying a small heartbeat interval reduces the amount of time it takes to detect a controller failure. The default value is disabled.
