Step 4
If you want to specify a secondary backup controller for all access points, specify the IP address of the secondary backup
controller in the Back-up Secondary Controller IP Address field and the name of the controller in the Back-up Secondary
Controller Name field.
The default value for the IP address is 0.0.0.0, which disables the secondary backup controller.

Step 6
If you want to configure primary, secondary, and tertiary backup controllers for a specific point, follow these steps:
a) Choose
Access Points > All APs
to open the All APs page.
b) Click the name of the access point for which you want to configure primary, secondary, and tertiary backup controllers.
c) Click the
High Availability
tab.
d) If desired, specify the name and IP address of the primary backup controller for this access point in the Primary
Controller fields.
Specifying an IP address for the backup controller is optional in this step and the next two steps. If the backup
controller is outside the mobility group to which the mesh access point is connected (the primary controller),
then you need to provide the IP address of the primary, secondary, or tertiary controller, respectively. The
controller name and IP address must belong to the same primary, secondary, or tertiary controller. Otherwise,
the mesh access point cannot join the backup controller.
Note
e) If desired, specify the name and IP address of the secondary backup controller for this mesh access point in the
Secondary Controller fields.
f) If desired, specify the name and IP address of the tertiary backup controller for this mesh access point in the Tertiary
Controller fields.
g) No change is required to the AP Failover Priority value. The default value for mesh access points is critical and it
cannot be modified.

Configuring Backup Controllers (CLI)
Using the controller CLI, follow these steps to configure primary, secondary, and tertiary controllers for a
specific mesh access point and to configure primary and secondary backup controllers for all mesh access
points.
Step 1
To configure a primary controller for a specific mesh access point, enter this command:
config ap primary-base controller_name Cisco_AP
[
controller_ip_address
]
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 mesh 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 mesh access point cannot join the backup controller.
Note
Step 2
To configure a secondary controller for a specific mesh access point, enter this command:
config ap secondary-base controller_name Cisco_AP
[
controller_ip_address
]
Step 3
To configure a tertiary controller for a specific mesh access point, enter this command:
config ap tertiary-base controller_name Cisco_AP
[
controller_ip_address
]
