Overview of VLANs

This section describes the concepts needed to configure and manage VLANs on IntraCore switches.

Benefits of VLAN Management

Unnecessary flooded traffic wastes bandwidth on a LAN, potentially clogging the network. Flooded traffic is traffic that is sent to all ports on the switch because the destination is a broadcast or multicast address, or because the location of the destination is unknown.

Traditional layer 2 bridges and switches attempt to limit unnecessary flooded traffic by learning the addresses of stations on the switch. But as traffic expands rapidly on today’s networks, bandwidth wastage from layer 2 flooding can easily become a network bottleneck.

The traditional solution to the problem of broadcast flooding is to use a layer 3 device like a router. The trade-offs that accompany the use of routers include higher initial cost, more latency with decreased network performance, and higher maintenance and configuration expenses.
