As a network increases in size, segmenting a single broadcast domain into multiple domains improves scalability, manageability, and security. However, doing so using physically with separate switches and routers is both static and expensive. Virtual LANs (VLANs) are a cost-effective method of segmenting and organizing a network. A single switch can be divided into multiple broadcast domains so that devices can be grouped and isolated; each logical segment is virtual LAN. Applying VLANs reduces broadcast traffic, introduces flexibility in the placement of devices on the network, and increases network security by allowing separate policies to be applied to each group. On a LAN users are bound to a physical location and performance is reduced with a large number of users VLANs can logically organize users into groups increasing performance Users on VLANs are not constrained to a physical location VLAN | 1015
