Table 7-2. VLAN Ports Fields
Note Ingress Filtering is enabled on all ports; therefore, a frame is discarded if the port is not a member of
the VLAN that the frame is associated with. In a tagged frame, the VLAN is identified by the VLAN ID
in the tag. In an untagged frame, the VLAN is the Port VLAN ID specified for the port that received this
frame.

immediately. Use the Maintenance > Save Configuration page to have the settings remain in effect
after a reboot.
Participation / Tagging
Use this page to include ports or trunks in particular VLANs and to specify the tagging policy for
outgoing packets on a port or trunk.
Note ■ All ports are members of VLAN1 by default.
■ Each port must be a member of at least one VLAN. An error message is displayed if a user
attempts to exclude a port from participation in its only VLAN.
■ 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.
To access the Participation / Tagging page, click VLANs > Participation / Tagging in the navigation pane.
As shown in the example configuration in Figure 7-3, VLAN 1 is selected for configuration. Ports 1, 2,
and 5 are configured as untagged members of VLAN1, and Trunk1 and Trunk2 are also members. Ports
3, and 4, and 7, and 8 are greyed-out because they are included in Trunk1 and Trunk2 respectively, and
receive their VLAN assignments from the trunk. Port 6 is greyed-out because it is configured as a
destination port in a port mirroring configuration, and cannot be assigned to a VLAN.
Field Description
Interface Select the port on which to configure the VLAN settings.
PVID The VLAN ID that this port will assign to untagged frames or priority-tagged frames received
on this port (range 1–4093, default = 1). The PVID is not user-configurable and always
corresponds to VLAN ID of the port’s untagged VLAN membership. You assign ports to VLANs
on the VLAN Participation / Tagging page.
The PVID value displays as None if all the VLANs are configured as tagged on this port or if this
port is configured as the destination port in a port mirroring configuration.
Port Priority Specify the default 802.1p priority assigned to untagged packets arriving at the port. A value of
0 indicates the lowest priority, commonly used for routine traffic, and 7 indicates the highest
priority, often reserved for application such as voice and video. (0–7, default = 0)
