Chapter 31: Port-based VLAN, Tagged VLAN, and Multiple VLAN Mode Commands
600 Section VI: Virtual LANs
– Actual: The current untagged ports of the VLAN. If you
are not using 802.1x port-based network access
control, both the Configured and Actual untagged ports
of a VLAN will always be the same.
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.
ˆ 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 71.
