The DNS setting is part of provisioning the AP. The easiest way to provision an AP is to use the Provisioning page in the WebUI. These instructions assume you are only modifying the controller information in the Master Discovery section of the Provision page.

NOTE: Reprovisioning the AP causes it to automatically reboot.

In the WebUI

1.Navigate to the Configuration > Wireless > AP Installation > Provisioning page. Select the remote AP and click Provision.

2.Under Master Discovery enter the master DNS name of the controller.

3.Click Apply and Reboot.

For more information, see "Provision the AP" on page 516.

Backup Controller List

Using DNS, the remote AP receives multiple IP addresses in response to a host name lookup. Known as the backup controller list, remote APs go through this list to associate with a controller. If the primary controller is unavailable or does not respond, the remote AP continues through the list until it finds an available controller. This provides redundancy and failover protection.

The remote AP loses the IP addresses information that is received through DNS when it terminates and receives the system profile configuration from the controller. If the remote AP loses connectivity on the IPSec tunnel to the controller, the RAP fails over from the primary controller to the backup controller. For this scenario, add the IP address of the backup controller in the backup LMS and the IP address of the primary controller in the LMS field of the ap-system profile.Network connectivity is lost during this time.As described in the section "Configuring Remote AP Failback" on page 533, you can also configure a remote AP to revert back to the primary controller when it becomes available.To complete this scenario, you must also configure the LMS IP address and the backup LMS IP address.

For example, assume you have two data centers, data center 1 and data center 2, and each data center has one master controller in the DMZ. You can provision the remote APs to use the controller in data center 1 as the primary controller, and the controller in data center 2 as the backup controller. If the remote AP loses connectivity to the primary, it will attempt to establish connectivity to the backup. You define the LMS parameters in the AP system profile.
