This read-only integer reports the current stage of the 802.1X Authenticator's state machine for this specific client session, such as connecting, authenticating, or fully authenticated. An administrator watches this in real time to pinpoint exactly where an authentication attempt is stuck, rather than just knowing it eventually failed. For example, a session stuck at connecting rather than progressing to authenticating suggests the client isn't successfully starting the EAP exchange, while one stuck at authenticating points to a problem further along, such as backend RADIUS communication.
