Setting The Router-To-Client Frame Retransmission Number - Cisco 7604 Configuration Manual

Configuring 802.1X Port-Based Authentication
Setting the Router-to-Authentication-Server Retransmission Time for Layer 4
Packets
The authentication server notifies the router each time it receives a Layer 4 packet. If the router does not
receive a notification after sending a packet, the router waits a set period of time and then retransmits
the packet. You may set the amount of time that the router 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 router to the authentication server,
perform this task:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# dot1x timeout server-timeout
seconds
Router(config-if)# no dot1x timeout
server-timeout
Step 3
Router(config-if)# end
Step 4
Router# show dot1x all
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to set the router-to-authentication-server retransmission time for Layer 4
packets to 25 seconds:
Router(config-if)# dot1x timeout server-timeout 25

Setting the Router-to-Client Frame Retransmission Number

In addition to changing the router-to-client retransmission time, you can change the number of times that
the router sends an EAP-request/identity frame (assuming no response is received) to the client before
restarting the authentication process.
You should change the default value of this command only to adjust for unusual circumstances such as
Note
unreliable links or specific behavioral problems with certain clients and authentication servers.
To set the router-to-client frame retransmission number, perform this task:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# dot1x max-req count
Router(config-if)# no dot1x max-req
