7-14 Advan ced Concep ts Vir tual LANs (V LANs) Advanc ed Concept s Vi rtual LANs (VLANs ) The switch suppor ts port-based virtual LANs (VLA Ns). A VLAN is a collection of ports that be long to a single broa dcast doma in. (That is, al l ports carryi ng traffic for a particula r subnet address w ould be long to the same VLAN.
