Vlan Management - Panasonic PN28080i-ID Operation Manual

4.7.1. VLAN Management

4.7.1.a. Features
Corresponding to IEEE802.1Q compatible Tag VLAN, a frame can be sent

with a VLAN tag (hereinafter referred to as just "tag").
Having two different parameters of VLAN ID and PVID, forwarding

destination of an untagged frame is determined by a combination of
these parameters.
VLAN ID

VLAN ID is a VLAN identifier placed on each frame in processing tagged
frames. As for an untagged frame, ports are divided into groups by this
ID, and the forwarding destination of the frame is determined by
referring to this ID. Multiple VLANs can be assigned to each port.
PVID (Port VLAN ID)

Only one PVID can be set to each port. When an untagged frame is
received, this ID determines to which VLAN the frame should be
forwarded. As for a tagged frame, this ID is not referred and VLAN ID in
the tag is used instead.
