Benefits of a Layer 2 Switch in a Network

Layer 2 switches in your network might offer some, or all, of the following benefits to you:

  • Bandwidth? Using a technique called microsegmentation, LAN switches provide increased performance for individual users because the switch allocates dedicated bandwidth to each switch port for each network segment.

  • VLANs? Recall from Chapter 8 that VLANs are created by LAN switches that group individual ports into logical switched workgroups. Communication between these ports requires a router.
