VLAN
7.1 Introduction
VLAN (Virtual Local Area Network) is basically a broadcast domain. In an ordinary switched network system, a
broadcast packet or an unknown destination MAC address packet is broadcasted to all ports and that will decrease
network performance dramatically. By grouping some ports into one VLAN, broadcast packets will be sent only to
the ports within that VLAN without affecting the traffic of other ports. Any two or more ports can be grouped as
one VLAN in the device, and an overlapping VLAN port is permitted.
