Configuring IEEE 802.1X Port-Based Authentication
Command
Step 3
Router(config-if)# dot1x timeout reauth-period
seconds
Router(config-if)# no dot1x timeout reauth-period
Step 4
Router(config-if)# end
Step 5
Router# show dot1x all
1.
type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to enable periodic reauthentication and set the number of seconds between
reauthentication attempts to 4000:
Router(config-if)# dot1x reauthentication
Router(config-if)# dot1x timeout reauth-period 4000
Manually Reauthenticating the Client Connected to a Port
Note
Reauthentication does not disturb the status of an already authorized port.
To manually reauthenticate the client connected to a port, perform this task:
Command
Step 1
Router# dot1x re-authenticate
1
interface type
Step 2
Router# show dot1x all
1.
type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
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
Initializing Authentication for the Client Connected to a Port
Initializing authentication disables any existing authentication before authenticating the client connected
