remains in the unauthorized state, but authentication can be retried. If the authentication server cannot be reached, the
switch can retransmit the request. If no response is received from the server after the specified number of attempts,
authentication fails, and network access is not granted.
When a client logs off, it sends an EAPOL-logoff message, causing the switch port to transition to the unauthorized state.
If the link state of a port transitions from up to down, or if an EAPOL-logoff frame is received, the port returns to the
unauthorized state.
