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
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.
