802.1Q/1P
12.1 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 P-660H-T1v3s to a VLAN group and configure the
settings for the group. You may also set the priority level for traffic trasmitted
through the ports.
