VLAN Overview
■
Configuring GARP/GVRP
■
A virtual local area network (VLAN) groups the devices of a LAN logically, but not
physically, into segments to implement the virtual workgroups.
Using 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, so VLAN configurations are very helpful in controlling
network traffic, saving device investment, simplifying network management and
improving security.
