Router(config-if)# dot1x reauthentication
Router(config-if)# dot1x timeout reauth-period 4000
Manually Reauthenticating the Client Connected to a Port

This example shows how to manually reauthenticate the client connected to Fast Ethernet port 5/1:
Router# dot1x re-authenticate interface fastethernet 5/1
Starting reauthentication on FastEthernet 5/1

periodic reauthentication is enabled.
Router(config-if)# no dot1x timeout reauth-period
Returns to the default reauthorization period.
Step 4
Router(config-if)# end
Returns to privileged EXEC mode.
