Chapter 6 VLAN
6.1 Introduction to VLAN
VLAN (Virtual Local Area Network) is a virtual local area network, is a kind of device by LAN
logical rather than physical division into a network, in order to achieve the virtual group
technology.
VLAN technology allows network administrators to one physical LAN logic into different
broadcast domains (or virtual LAN, VLAN), each VLAN contains a set of computer
workstations have the same needs, have the same properties and physical form on LAN.
But because it is logical rather than physical partition, so each workstation with a VLAN does
not need to be placed in the same physical space, namely the workstation does not
necessarily belong to the same physical LAN segment. Within a VLAN broadcast and
unicast traffic will not be forwarded to the other VLAN, helps to control the flow, reduce
equipment investment, simplifying the management of network, improve network security.
The switch supports 802.1Q VLAN and port based VLAN (Port-based VLAN).
