Chapter 7 Configuring 802.1X Port-Based Authentication
Displaying 802.1X Statistics and Status
To disable multiple hosts on the port, use the no dot1x multiple-hosts interface configuration command.
This example shows how to enable 802.1X on Fast Ethernet interface 0/1 and to allow multiple hosts:
Switch(config)# interface fastethernet0/1
Switch(config-if)# dot1x port-control auto
Switch(config-if)# dot1x multiple-hosts
Resetting the 802.1X Configuration to the Default Values
Beginning in privileged EXEC mode, follow these steps to reset the 802.1X configuration to the default
values:
Displaying 802.1X Statistics and Status
To display 802.1X statistics for all interfaces, use the show dot1x statistics privileged EXEC command.
To display 802.1X statistics for a specific interface, use the show dot1x statistics interface interface-id
privileged EXEC command.
To display the 802.1X administrative and operational status for the switch, use the show dot1x
privileged EXEC command. To display the 802.1X administrative and operational status for a specific
