Displaying 802.1X Configuration, Statistics, and Counters

Status Indicator	Meaning
Unauthorized VLAN	< vlan-id>: Lists the VID of the static VLAN configured as the unauthorized VLAN for the indicated
ID	port.
	0: No unauthorized VLAN has been configured for the indicated port.

Authorized VLAN ID	< vlan-id >: Lists the VID of the static VLAN configured as the authorized VLAN for the indicated port.
Authorized VLAN ID	0: No authorized VLAN has been configured for the indicated port.

Current VLAN ID	< vlan-id>: Lists the VID of the static, untagged VLAN to which the port currently belongs.
	No PVID: The port is not an untagged member of any VLAN.

Syntax: show vlan < vlan-id>

Displays the port status for the selected VLAN, including an indication of which port memberships have been temporarily overridden by Open VLAN mode.

Note that ports B1 and B3 are not in the upper listing, but are included under “Overridden Port VLAN configuration”. This shows that static, untagged VLAN memberships on ports B1 and B3 have been overridden by temporary assignment to the authorized or unauthorized VLAN. Using the show port- access authenticator < port- list > command shown in figure 8-5 provides details.
