To detect errors, filter the dot1x verbose messages that are enabled by default.
Step 2 Use the show dot1x interface statistics command to display IEEE 802.1x statistics for a specific port.
Step 3 Use the show dot1x all command to display the IEEE 802.1x administrative and operational status for
a switch.
