TochangeVAP0ortoenableandconfigureadditionalVAPs,selecttheVAPtabintheManagesection.
VAPssegmentthewirelessLANintomultiplebroadcastdomainsthatarethewirelessequivalentofEthernet
VLANs.VAPssimulatemultipleAPsinonephysicalAP.Eachradiosupportsupto16VAPs.
For
eachVAP,youcancustomizethesecuritymodetocontrolwirelessclientaccess.EachVAPcanalsohavea
uniqueSSID.MultipleSSIDsmakeasingleAPlookliketwoormoreAPstoothersystemsonthenetwork.By
configuringVAPs,youcanmaintainbettercontroloverbroadcastand
multicasttraffic,whichaffectsnetwork
performance.
YoucanconfigureeachVAPtouseadifferentVLAN,oryoucanconfiguremultipleVAPstousethesameVLAN,
whethertheVLANisonthesameradiooronadifferentradio.VAP0,whichisalwa ysenabledonbothradios,
isassignedto
thedefaultVLAN1.
TheAPaddsVLANIDtagstowirelessclienttrafficbasedontheVLANIDyouconfigureontheVAPpageorby
usingtheRADIUSserverassignment.IfyouuseanexternalRADIUSserver,youcanconfiguremultipleVLANs
oneachVAP .TheexternalRADIUSserver
assignswirelessclientstotheVLANwhentheclientsassociateand
authenticate.
YoucanconfigureuptofourglobalIPv4orIPv6RADIUSservers.Oneoftheserversalw aysactsasaprimary
whiletheothersactasbackupservers.Thenetworktype(IPv4orIPv6)andaccountingmodearecommon

acrossallconfiguredRADIUSservers.YoucanconfigureeachVAPtousetheglobalRADIUSserversettings,
whichisthedefault,oryoucanconfigureaper‐VAPRADIUSserverset.YoucanalsoconfigureseparateRADIUS
serversettingsforeachVAP .Forexample,youcanconfigureoneVAPto
useanIPv6RADIUSserverwhileother
VAPsusetheglobalIPv4RADIUSserversettingsyouconfigure.
IfwirelessclientsuseasecuritymodethatdoesnotcommunicatewiththeRAIDUSserver,oriftheRADIUS
serverdoesnotprovidetheVLANinformation,youcanassignaVLANIDtoeach
VAP .TheAPassignstheVLAN
toallwirelessclientsthatconnecttotheAPthroughthatVAP.
TosetupmultipleVAPs,clickManage>VAP.
Note:BeforeyouconfigureVLANsontheAP,besuretoverifythattheswitchandDHCPservertheAP
usescansupportIEEE802.1QVLANencapsulation.
