dot1x port-control
• Switch Port Analyzer (SPAN) destination port—You can enable 802.1X on a port that is a SPAN
destination port; however, 802.1X is disabled until the port is removed as a SPAN destination. You
can enable 802.1X on a SPAN source port.
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.
