Displaying the Authentication Sessions

Use the show authentication sessions command to view details of the 802.1X authentication or MAC authentication sessions, such as the ports, MAC addresses, IP addresses, and VLANs, as shown in the following example.

The following example displays sessions for a specific interface.

device(config)# show authentication sessions ethernet 2/1/25

The following example displays sessions for a specific stack unit.

device(config)# show authentication sessions unit 1

The following example displays a brief description of authentication sessions. Notice that Port 1/1/7 shows 4 authentication attempts, 1 authorized user, and 3 denied users, with the Untagged VLAN Type of RADIUS-VLAN. This is the case when at least one of the users on the same single untagged VLAN is using a RADIUS-returned VLAN. (The critical VLAN, restricted VLAN, guest VLAN, and dynamically allocated VLAN can be the same, and any of these can be assigned by the RADIUS server.)
