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.
