Chapter 21: Port-based and Tagged VLANs
358 Secton V: Virtual LANs
ˆ 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 a port to be in
different VLAN than the virtual LAN where it was originally
assigned as an untagged port. 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.
