Description
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.
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.
Client may have intentionally terminated usage or
may have experienced a service disruption.
Client may have intentionally terminated usage or
it could indicate an authentication issue.
Check disable, key mismatch or other
configuration issues.
