Displaying the 802.1X authentication sessions

Use the show dot1x sessions command to view details of the 802.1X authentication sessions, such as the ports, MAC addresses, IP addresses, VLANs, and so on.
Note: The IP address of the authenticated host is displayed only if an IP ACL is applied to the interface based on the RADIUS server response.

The following example displays 802.1X sessions for all interfaces. 

device(config)# show dot1x sessions all
