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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.

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.
