802.1Q VLAN Configuration

ThischapterdescribestheD‐Series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tha t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.

Creating a Secure Management VLAN

Bydefaultatstartup,thereisoneVLANconfiguredontheD‐Seriesdevice.ItisVLANID1,the

DEFAULTVLAN .The defaultcommunity name,whichdeterminesremoteaccessforSNMP

management,issetto“public”withread‐writeaccess.
