Page 4 highlights

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 the need for routers, by using faster switching instead. Other VLAN utilities include: 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. 4

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 the need for routers, by using faster switching instead. Other VLAN utilities include:
±
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.
