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.
