Chapter 1 VLAN Configuration
1.1 VLAN Overview
Virtual Local Area Network (VLAN) groups the devices of a LAN logically but not
physically into segments to implement the virtual workgroups. IEEE issued the IEEE
802.1Q in 1999, which was intended to standardize VLAN implementation solutions.
Through VLAN technology, network managers can logically divide the physical LAN
into different broadcast domains. Every VLAN contains a group of workstations with the
same demands. The workstations of a VLAN do not have to belong to the same
physical LAN segment.
With VLAN technology, the broadcast and unicast traffic within a VLAN will not be
forwarded to other VLANs, therefore, it is very helpful in controlling network traffic,
saving device investment, simplifying network management and improving security.
1.2 Configure VLAN
To configure a VLAN, first create a VLAN according to the requirements.
Main VLAN configuration includes:
