• 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.
Examples
# Set the server timeout timer to 150 seconds.

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.
Examples
# Enable the unicast trigger function on Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
