Specifying the DNS Controller Setting
In addition to specifying IP addresses for controllers, you can also specify the master DNS name for the
controller when provisioning the remote AP. The name must be resolved to an IP address when attempting to
set up the IPSec tunnel. For information on how to configure a host name entry on the DNS server, refer to the
vendor documentation for your server. It is recommended to use a maximum of 8 IP addresses to resolve a
controller name.
If the remote AP gets multiple IP addresses responding to a host name lookup, the remote AP can use one of
them to establish a connection to the controller. For more detailed information, see the next section Backup
Controller List on page 653.
Specifying the name also lets you move or change remote AP concentrators without reprovisioning your APs.
For example, in a DNS load-balancing model, the host name resolves to a different IP address depending on
the location of the user. This allows the remote AP to contact the controller to which it is geographically closest.
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.
Reprovisioning the AP causes it to automatically reboot.
