As the medium is shared, collisions and excessive broadcasts cannot beavoided on an Ethernet. To address the issue, virtual LAN (VLAN) was introduced.The idea is to break a LAN down into separate VLANs, that is, Layer 2 broadcast domains wherebyframes are switched between ports assigned to the same VLAN. VLANs are isolated from each other atLayer 2. A VLAN is a bridging domain, and all broadcast traffic is contained within it, as shown in Figure8-1.
