802.1Q/1P
13.1 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.
