CHAPTER 14
802.1Q/1P
14.1 Overview
This chapter describes how to configure the 802.1Q/1P settings.
A Virtual Local Area Network (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
ZyXEL Device to a VLAN group and configure the settings for the group. You may also set
the priority level for traffic trasmitted through the ports.

14.1.1 What You Can Do in the 802.1Q/1P Screens
• Use the Group Setting screen (Section 14.2 on page 219) to activate 802.1Q/1P, specify
the management VLAN group, display the VLAN groups and configure the settings for
each VLAN group.
• Use the Port Setting screen (Section 14.3 on page 222) to configure the PVID and assign
traffic priority for each port.
14.1.2 What You Need to Know About 802.1Q/1P
IEEE 802.1P Priority
IEEE 802.1P specifies the user priority field and defines up to eight separate traffic types by
inserting a tag into a MAC-layer frame that contains bits to define class of service.
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.
