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

d.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.
