NetComm NP3024 manual Vlan Virtual Local Area Network

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.
