14.1 Overview

This chapter describes how to assign ports into Virtual Local Area Networks (VLAN) and configure
frame tagging settings.
A VLAN allows a physical network to be partitioned into multiple logical networks. A VLAN group can
be treated as an individual device. Each group can have its own rules about where and how to
forward traffic. You can assign any ports on the Device to a VLAN group and configure the settings
for the group.

14.1.2 What You Need to Know About 802.1Q

IEEE 802.1Q Tagged VLAN
Tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of
a frame across bridges - they are not confined to the device on which they were created. The VLAN
ID associates a frame with a specific VLAN and provides the information that devices need to
process the frame across the network.
Forwarding Tagged and Untagged Frames
Each port on the device is capable of passing tagged or untagged frames. To forward a frame from
an 802.1Q VLAN-aware device to an 802.1Q VLAN-unaware device, the Device first decides where
to forward the frame and then strips off the VLAN tag. To forward a frame from an 802.1Q VLAN-
unaware device to an 802.1Q VLAN-aware switch, the Device first decides where to forward the
frame, and then inserts a VLAN tag reflecting the ingress port's default VID. The default PVID is
VLAN 1 for all ports, but this can be changed.
Whether to tag an outgoing frame depends on the setting of the egress port on a per-VLAN, per-
port basis (recall that a port can belong to multiple VLANs). If the tagging on the egress port is
