The network device uses the following 802.1X timers: • Handshake timer (handshake-period)-Sets the interval at which the access device sends client handshake requests to check the online status of a client that has passed authentication. If the device receives no response after sending the maximum number of handshake requests, it considers that the client has logged off. • Quiet timer (quiet-period)-Starts when a client fails authentication. The access device must wait the time period before it can process the authentication attempts from the client. • Periodic re-authentication timer (reauth-period)-Sets the interval at which the network device periodically re-authenticates online 802.1X users. To enable periodic online user re-authentication on a port, use the dot1x re-authenticate command. The change to the periodic re-authentication timer applies to the users that have been online only after the old timer expires. • Server timeout timer (server-timeout)-Starts when the access device sends a RADIUS Access-Request packet to the authentication server. If no response is received when this timer expires, the access device retransmits the request to the server. • Client timeout timer (supp-timeout)-Starts when the access device sends an EAP-Request/MD5 Challenge packet to a client. If no response is received when this timer expires, the access device retransmits the request to the client. • Username request timeout timer (tx-period)-Starts when the device sends an EAP-Request/Identity packet to a client in response to an authentication request. If the device receives no response before this timer expires, it retransmits the request. The timer also sets the interval at which the network device sends multicast EAP-Request/Identity packets to detect clients that cannot actively request authentication.
