Vlan Management - Panasonic PN28160A 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.
