Chapter 27: Port-based, Tagged, and Multiple Mode VLAN Commands

Section V: Virtual LANs
If you are using 802.1x and you assigned a guest VLAN to an
authenticator port or you associated an 802.1x supplicant to a
VLAN on the authentication server, it is possible for ports to be in
different VLANs than the virtual LANs where they were originally
assigned as untagged ports. In these situations, the Configured
and Actual port lists can differ, with the Actual list detailing the
ports that are currently functioning as untagged ports of the VLAN.
For example, if a particular port is listed as a Configured member
of a VLAN, but not as an Actual member, that would mean either
the port is currently a part of a Guest VLAN or the supplicant who
logged on the port was associated with a VLAN assignment on the
authentication server.
Tagged port(s) - The tagged ports of the VLAN. A tagged port can
belong to more than one VLAN at a time.
An example of the information displayed by this command for the 802.1Q-
compliant multiple VLAN mode is shown in Figure 47.
Figure 47. SHOW VLAN Command for the 802.1Q-compliant Multiple
VLAN Mode
The information displayed by the command is described here:
VLAN name - The name of the VLAN. The name is Client_VLAN
followed by the port number.
VLAN ID - The ID number assigned to the VLAN.
Protected Ports - The status of protected ports. Since the VLANs of a
multiple VLAN mode are not protected ports VLANs, this will be No.
