Chapter 7 Controlling Lightweight Access Points

Configuring Backup Controllers

Step 7 If you want to specify a primary backup controller for all access points, enter the IP address of the

primary backup controller in the Back-up Primary Controller IP Address field and the name of the

controller in the Back-up Primary Controller Name field.

Note The default value for the IP address is 0.0.0.0, which disables the primary backup controller.

Step 8 If you want to specify a secondary backup controller for all access points, enter 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.

Note The default value for the IP address is 0.0.0.0, which disables the secondary backup controller.

Step 9 Click Apply to commit your changes.

Step 10 If you want to configure primary, secondary, and tertiary backup controllers for a specific point, follow

these steps:

a. Click 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 to open the All APs > Details for (High Availability) page (see

Figure 7-15).

Figure 7-15 All APs > Details for (High Availability) Page

If desired, enter the name and IP address of the primary backup controller for this access point in

the Primary Controller fields.

Note Entering 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 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 access point

cannot join the backup controller.

e. If desired, enter the name and IP address of the secondary backup controller for this access point in

the Secondary Controller fields.
