5.4.9 Virtual LAN
Concept
The concept of VLAN was introduced as a way to solve many of the issues of a large
Layer 2 environment. It controls the traffic on a physical LAN. The physical LAN is
partitioned into multiple virtual LANs. Each VLAN is assigned a number, called the
VID, that identifies it uniquely within the network. Traffic between these systems
stays bottled up within their VLAN.
Although different VLANs use a common physical network, the traffic of each VLAN
is isolated from the other VLANs.
