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 Gigabit Ethernet 1/1:
Switch(config)# interface gigabitethernet1/1
Switch(config-if)# dot1x port-control auto
Switch#
You can verify your settings by using the show dot1x all or show dot1x interface int commands to show
the port-control status. An enabled status indicates that the port-control value is set either to auto or to
force-unauthorized.
