What is a VLAN?

VLANs or Virtual Local Area Networks are a way of partitioning physical network devices into virtual clusters based on factors such as function, hierarchy, or application without having to take into consideration the physical location of the device.

Why use a VLAN?

  • Better network performance: VLANs improve network performance by separating large broadcast domains into smaller ones. If a device in one VLAN sends broadcast data, only devices in that VLAN receive the data, and devices in other VLANs do not.
  • Improved security: Hosts containing sensitive data can be separated from the rest of the network.
  • Lowered cost: Without network segmentation, each subnet will require its own router. Segmenting a network into smaller VLANs is cheaper than creating networks with multiple routers.
  • Simplified administration: Grouping users into the virtual networks makes it easy to set up and control network policies at a group level.
