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 switch.
3. Click Apply and Reboot.

Backup Switch List
Using DNS, the remote AP receives multiple IP addresses in response to a host name lookup. Known as the
backup switch list, remote APs go through this list to associate with a switch. If the primary switch is unavailable
or does not respond, the remote AP continues through the list until it finds an available switch. This provides
redundancy and failover protection.
The remote AP loses the IP address information received through DNS when it terminates and receives the
system profile configuration from the switch. If the remote AP loses connectivity on the IPSec tunnel to the
switch, the RAP fails over from the primary switch to the backup switch. For this scenario, add the IP address of
the backup switch in the backup LMS and the IP address of the primary switch 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 721, you can also configure a remote AP to revert back to the primary switch 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 switch in the DMZ. You can provision the remote APs to use the switch in data center 1 as the primary
switch, and the switch in data center 2 as the backup switch. 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.
