ThischapterdescribestheEnterasysB5system’scapabilitiestoimplement802.1QvirtualLANs

(VLANs).

VLAN Configuration Summary

VirtualLANsallowthenetworkadministratortopartitionnetworktrafficintologicalgroupsand

controltheflowofthattrafficthroughthenetwork.Oncethetrafficand,ineffect,theusers

creatingthetraffic,areassignedtoaVLAN,thenbroadcastandmulticasttrafficiscontained

withintheVLANandusers

canbeallowedordeniedaccesstoanyofthenetwork’sresources.

Also,someoralloftheportsonthedevicecanbeconfiguredasGVRPports,whichenableframes

receivedwithaparticularVLANIDandprotocoltobetransmittedonalimitednumberofports.

Thiskeeps

thetrafficassociatedwithaparticularVLANandprotocolisolatedfromtheotherparts

ofthenetwork.
