dot1x port-control
• EtherChannel port—Before enabling 802.1x on the port, you must first remove it from the
EtherChannel. If you try to enable 802.1x on an EtherChannel or on an active port in an
EtherChannel, an error message appears, and 802.1x is not enabled. If you enable 802.1x on a
not-yet active port of an EtherChannel, the port does not join the EtherChannel.
• Switched Port Analyzer (SPAN) and Remote SPAN (RSPAN) destination ports—You can enable
802.1x on a port that is a SPAN or RSPAN destination port. However, 802.1x is disabled until the
port is removed as a SPAN or RSPAN destination. You can enable 802.1x on a SPAN or RSPAN
source port.
To globally disable 802.1x on the switch, use the no dot1x system-auth-control global configuration
command. To disable 802.1x on a specific port, use the no dot1x port-control interface configuration
command.
Examples This example shows how to enable 802.1x on a port:
Switch(config)# interface fastethernet1/0/1
Switch(config-if)# dot1x port-control auto
You can verify your settings by entering the show dot1x [interface interface-id] privileged EXEC
command.
