This read-only counter tracks how many times this session's 802.1X authenticator state machine has entered the CONNECTING state from any other state, the point where the switch begins actively trying to authenticate the client. An administrator watches this for unusually high counts, which can indicate a client repeatedly restarting the authentication process rather than completing it cleanly. For example, a rapidly incrementing count here combined with few successful authentications suggests a client stuck in an authentication retry loop.
