VLANs provide some of the following benefits:

❒Reduced costs

As a company grows and reorganizes, physical moves, adds, and re-cabling are made to their network. VLANs provide a cost effective solution to network changes. Because VLANs are location independent, adds and moves are quickly accomplished without the need to rewire the physical infrastructure.

❒Better security

VLANs offer security by logically separating groups by departments, functions, etc., therefore, limiting and/or restricting user access and priviledges to specific applications and resources.

❒Efficient use of network bandwidth

VLANs maximize the efficient use of bandwidth on any given LAN segment, since packets are forwarded only between segments as required. In addition, VLANs create smaller broadcast domains which reduce the amount of broadcast traffic across the entire network.
