Manually Re-Authenticating a Client Connected to a Port
You can manually re-authenticate the client connected to a specific por t at any time by entering the dot1x
re-authenticate interface interface-id privileged EXEC command. If you want to enable or disable
periodic re-authentication, see the “Enabling Periodic Re-Authentication” section on page 8-10.
This example shows how to manually re-authenticate the client connect ed t o Fast E ther ne t po rt 0 / 1:
Switch# dot1x re-authenticate interface fastethernet0/1
Starting reauthentication on FastEthernet0/1
Changing the Quiet Period
When the switch cannot authenticate the client, the switch remains idle for a set period of time, and then
tries again. The idle time is determined by the quiet-period value. A failed authentication of the client
might occur because the client provided an invalid password. You can provide a faster response time to
the user by entering a smaller number than the default.
Beginning in privileged EXEC mode, follow these steps to change the quiet period:
To return to the default quiet time, use the no dot1x timeout quiet-period global configuration
command.
This example shows how to set the quiet time on the switch to 30 seconds:
Switch(config)# dot1x timeout quiet-period 30
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 dot1x timeout quiet-period seconds Set the number of seconds that the switch remains in the quiet state
following a failed authentication exchange with the client.
The range is 0 to 65535 seconds; the default is 60.
Step3 end Return to privileged EXEC mode.
Step4 show dot1x Verify your entries.
Step5 copy running-config startup-config (Optional) Save your entries in the configuration file.
