6.4 VLAN
AvirtualLAN(VLAN)isanybroadcastdomainthatispartitionedandisolatedinacomputernetworkatthe
datalinklayer(OSIlayer2).VLANsaredatalinklayer(OSIlayer2)constructs,analogoustoIPsubnets,which
arenetwork‐layer(OSIlayer3)constructs.VLANscanbeusedtopartitionalocalnetworkintoseveral
distinctivesegments.
VLANtechnologyprovidesthefollowingadvantages:
1. BroadcasttrafficdoesnotcrossintodifferentVLANs,whichreducesbandwidthutilizationand
improvesnetworkperformance.
2. SecurityinyourLANcanbeimproved,sincepacketsindifferentVLANscannotcommunicatewith
eachotherdirectly.
3. WithVLAN,clientscanbeallocatedtodifferentworkinggroups,andusersfromthesamegroupdo
