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.
To configure a primary controller for a specific access point, enter this command:
Step 1
config ap primary-base controller_name Cisco_AP [controller_ip_address]
Note
To configure a secondary controller for a specific access point, enter this command:
Step 2
config ap secondary-base controller_name Cisco_AP [controller_ip_address]
Step 3 To configure a tertiary controller for a specific access point, enter this command:
config ap tertiary-base controller_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
To configure a secondary backup controller for all access points, enter this command:
Step 5
config advanced backup-controller secondary backup_controller_name
backup_controller_ip_address
Note
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.

If desired, enter the name and IP address of the tertiary backup controller for this access point in the
Tertiary Controller fields.
Click Apply to commit your changes.
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.
To delete a primary or secondary backup controller entry, enter 0.0.0.0 for the controller IP
address.
