Configuring 802.1X Port-Based Authentication

Setting the Switch-to-Client Retransmission Time for EAP-Request Frames

The client notifies the switch that it received the EAP-request frame. If the switch does not receive this
notification, the switch waits a set period of time, and then retransmits the frame. You may set the
amount of time that the switch waits for notification from 1 to 65535 seconds. (The default is 30
seconds.)

To set the switch-to-client retransmission time for the EAP-request frames, perform this task:

This example shows how to set the switch-to-client retransmission time for the EAP-request frame to
25 seconds:

Router(config-if)# dot1x timeout supp-timeout 25

Setting the Switch-to-Authentication-Server Retransmission Time for Layer 4
Packets

The authentication server notifies the switch each time it receives a Layer 4 packet. If the switch does
not receive a notification after sending a packet, the switch waits a set period of time and then retransmits
the packet. You may set the amount of time that the switch waits for notification from 1 to 65535
seconds. (The default is 30 seconds.)

To set the value for the retransmission of Layer 4 packets from the switch to the authentication server,
perform this task:
