Known Affected Releases
Symptom: No port violation is triggered when a new MAC address is seen on the interface, before dot1x idle-timeout occurs. Conditions: Port is configured for authentication order dot1x mab, closed mode, authentication violation restrict and authentication timer inactivity. A client is authenticated behind a IP phone not supporting EAPoL Logoff or CDP 2nd Port Notification - the client is then replaced with a device not supporting dot1x before the idle-timeout period expires.
