Error Message
Description

apf_utils.c 680: Received a CIF field without the protected bit set from mobile xx:xx:xx:xx:xx:xx

A client is sending an association request on a security-enabled WLAN with the protected bit set to 0 (in the Capability field of the association request). As designed, the controller rejects the association request, and the client sees an association failure.

dtl_arp.c 480: Got an idle-timeout message from an unknown client xx:xx:xx:xx:xx:xx

The controller's network processing unit (NPU) sends a timeout message to the central processing unit (CPU) indicating that a particular client has timed out or aged out. This normally occurs when the CPU has removed a wireless client from its internal database but has not notified the NPU. Because the client remains in the NPU database, it ages out on the network processor and notifies the CPU. The CPU finds the client that is not present in its database and then sends this message.

STATION_DISASSOCIATE

Client may have intentionally terminated usage or may have experienced a service disruption.

STATION_DEAUTHENTICATE

Client may have intentionally terminated usage or it could indicate an authentication issue.

STATION_AUTHENTICATION_FAIL

Check disable, key mismatch or other configuration issues.

STATION_ASSOCIATE_FAIL

Check load on the Cisco Radio or signal quality issues.

LRAD_ASSOCIATED
