Virtual LANs

A Virtual LAN (VLAN) is a logical grouping of network devices put together as a LAN regardless of their physical grouping. VLANs let a user see and access only specified network segments and limits collision domains. This increases network performance and allows network security.

VLANs offer the ability to group computers together into logical workgroups. This can simplify network administration when connecting clients to servers that are geographically dispersed across the building, campus, or enterprise network.

Typically, VLANs consist of co-workers within the same department but in different locations, groups of users running the same network protocol, or a cross-functional team working on a joint project. 

 

By using VLANs on your network, you can:
