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.
