Field
Description
VLAN ID
Select the VLAN ID for which you want to view interface memberships.
Interface
The port or trunk ID.
Participation/Tagging
The current membership mode and tagging behavior for each port in this VLAN, which is one
of the following:
Exclude—The port is not configured to be a member of the selected VLAN.
Tagged—The port is a tagged member of the selected VLAN. When frames in this VLAN
are forwarded on this port, the VLAN ID will be included in the frame’s Ethernet header.
Untagged—The port is an untagged member of the selected VLAN. When frames in this
VLAN are forwarded on this port, the VLAN ID will not be included in the frame’s Ether-
net header.
NOTE:
Consider the following guidelines when editing VLAN port memberships and settings:
A port can be an untagged member of only one VLAN. If you change the VLAN that a port is an
untagged member of, then the port will be excluded from the VLAN where it was previously an
untagged member. A port can be a tagged member of multiple VLANs.
All ports must be a member of at least one VLAN, as either a tagged or an untagged member.
You cannot exclude a port from a VLAN unless the port is a member of at least one other VLAN.
If you exclude a port from the management VLAN, a computer connected to the switch via that
port will be unable to access the switch management interface.
Ports belonging to a trunk cannot be assigned membership in a VLAN, although the trunk itself
can be a member of one or more VLANs. When a member port is added to a trunk, it loses any
previous VLAN memberships and acquires those of the trunk. When deleted from a trunk, a port
loses the VLAN memberships of the trunk and acquires untagged membership in VLAN 1.
