Chapter9 Configuring IEEE 802 .1x Port-Based Authentication
Configuring IEEE 802.1x Authentication
To return to the default retransmission time, use the no dot1x timeout tx-period interface configuration
command.
This example shows how to set 60 as the number of seconds that the switch waits for a response to an
EAP-request/identity frame from the client before rese nding the request:
Switch(config-if)# dot1x timeout tx-period 60
Setting the Switch-to-Client Frame-Retransmission Number
In addition to changing the switch-to-client retransmiss ion time, you can change the number of times
that the switch sends an EAP-request/identity frame (assuming no response is received) to the client
before restarting the authentication process.
Note You should change the default value of this command only to adjust for unusual circumstances such a s
unreliable links or specific behavioral problems with certain clients and authentication servers.
Beginning in privileged EXEC mode, follow these steps to set the switch-to-client frame-retransmission
number. This procedure is optional.
To return to the default retransmission number, use the no dot1x max-req interface configuration
command.
This example shows how to set 5 as the number of times that the switch sends an EAP-request/identity
request before restarting the authentica tion process:
Switch(config-if)# dot1x max-req 5
Setting the Re-Authentication Number
You can also change the number of times that the switch restarts the authentication process before the
port changes to the unauthorized state.
Step4 end Return to privileged EXEC mode.
Step5 show dot1xinterface interface-id Verify your entries.
Step6 copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 interface interface-id Specify the port to be configured, and enter interface configuration mode.
Step3 dot1x max-reauth-req count Set the number of times that the switch sends an EAP-request/identity
frame to the client before restarting the authentication process. The range
is 1 to 10; the default is 2.
Step4 end Return to privileged EXEC mode.
Step5 show dot1x interface interface-id Verify your entries.
Step6 copy running-config startup-config (Optional) Save your entries in the configuration file.
