What Is a VLAN?
A VLAN is a switched network that is logically segmented on an organizational
basis, by function, project team, or application, rather than on a physical or
geographical basis. For example, all workstations and servers used by a particular
workgroup team can be connected to the same VLAN, regardless of their physical
connections to the network or their intermingling with other teams. The network
can be reconfigured by using software rather than by physically unplugging and
moving the devices or wires.
