• 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.

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.

Usage guidelines
The unicast trigger function enables the network access device to initiate 802.1X authentication when it
receives a data frame from an unknown source MAC address. The device sends a unicast Identity
EAP/Request packet to the unknown source MAC address, and retransmits the packet if it has received
no response within a period of time (set with the
dot1x timer tx-period
command). This process continues
until the maximum number of request attempts (set with the
dot1x retry
command) is reached.
