dot1x port-control

•
To globally disable 802.1X on the switch, you must disable it on each port. There is no global
configuration command for this task.
Examples This example shows how to enable 802.1X on Fast Ethernet interface 0/1:
Switch(config)# interface fastethernet0/1
Switch(config-if)# dot1x port-control auto
You can verify your settings by entering the show dot1x privileged EXEC command and checking the
Status column in the 802.1X Port Summary section of the output. An enabled status means the
port-control value is set either to auto or to force-unauthorized.
