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 utility of using VLAN is to
reduce latency and need for routers, using faster switching
instead. Other VLAN utility includes:
Security, Security is increased with the reduction of opportunity
in eavesdropping on a broadcast network because data will be
switched to only 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) VLAN is the common method of
implementing a VLAN, and is the one supplied in the Switch.
