VLAN (Virtual Local Area Network)
A VLAN is a group of end-stations that are not constrained by their physical location and can
communicate as if a common broadcast domain, a LAN. The primary reason for using a VLAN is to
reduce latency and the need for routers. Other VLAN benefits include:
Security Security is increased with the reduction of opportunity in
eavesdropping on a broadcast network, because data will
only be switched to those confidential users within the
VLAN.
Cost Reduction VLANs can be used to create multiple broadcast
domains, thus eliminating the need of expensive routers.
Port-based (or port-group) Port-based is the common method of implementing a
VLAN, and is the one supplied in the Switch.
