Controller Discovery Process

To support the IW916I AP, the controller must be running Cisco IOS XE Dublin 17.12.1 or a later release.
For more information, see the
Guidelines and Limitations
• It is not possible to edit or query an access point using the controller CLI if the name of the access point
• Make sure that the controller is set to the current time. If the controller is set to a time that has already
The controller must discover AP before it can become an active part of the network. The AP supports the
following controller discovery processes:
• Locally stored controller IP address discovery: If the AP was previously joined to a controller, the primary,
• DHCP server discovery: This feature uses DHCP option 43 to provide controller IP address to the AP.
• DNS discovery: The AP can discover controllers through your domain name server (DNS). For the AP

secondary, and tertiary controllers' IP addresses are stored in the AP's non-volatile memory. This process
of storing controller IP addresses on an AP for later deployment is called priming the AP. For more
information about priming, see
Cisco switches support a DHCP server option that is typically used for this capability. For more information
about DHCP option 43, see
to do so, you must configure your DNS to return controller IP addresses in response to
CISCO-CAPWAP-CONTROLLER.localdomain, where localdomain is the AP domain name. Configuring
the CISCO-CAPWAP-CONTROLLER provides backward compatibility in an existing customer
deployment. When an AP receives an IP address and DNS information from a DHCP server, it contacts
