Troubleshooting the Access Point Join Process
Access points can fail to join a controller for many reasons: a RADIUS authorization is pending; self-signed certificates are not
enabled on the controller; the access point's and controller's regulatory domains don't match, and so on.
Controller software enables you to configure the access points to send all CAPWAP-related errors to a syslog server. You do not
need to enable any debug commands on the controller because all of the CAPWAP error messages can be viewed from the syslog
server itself.
The state of the access point is not maintained on the controller until it receives a CAPWAP join request from the access point.
Therefore, it can be difficult to determine why the CAPWAP discovery request from a certain access point was rejected. In order
to troubleshoot such joining problems without enabling CAPWAP debug commands on the controller, the controller collects
information for all access points that send a discovery message to it and maintains information for any access points that have
successfully joined it.
The controller collects all join-related information for each access point that sends a CAPWAP discovery request to the
controller. Collection begins with the first discovery message received from the access point and ends with the last configuration
payload sent from the controller to the access point.
