7.6(120.0)

Description (partial)

Symptom:
A AP in flexConnect local auth should not send a access-request packet to radius if no username/password. The Radius should send a reject back to the AP but in our case the ACS 4.2 does not. This causes the AP to mark the server as dead.

Conditions:
flexconnect local switching local auth. Radius not configured (or bug) to send back access-reject. If the reject is not sent the AP will mark it as dead.

using leap/peap. very random behaviour - seen 1-2 times a day.

called-station-id is sent in this packet but blank username.
