ThefollowingrulesapplytothelocalVMgroupconfigurationcommands:
 cpu:EnablesendingunregisteredIPMCtoCPU.
 flood:EnablefloodingunregisteredIPMC.
 key:AddLACPLAGstothegroup.
 optflood:EnableoptimizedfloodingtoallowsendingunregisteredIPMCto
theMrouterportswithouthavinganypacketlossduringthelearningperiod;
Thisoptionisdisabledbydefault;Whenoptfloodisenabled,thefloodandcpu
settingsareignored.
 port:Addswitchserverportsorswitchuplinkportstothegroup.Notethat
VMgroupsandvNICs(see“VirtualNICs”onpage 261)arenotsupported
simultaneouslyonthesameport.
 portchannel:AddstaticportLAGstothegroup.
 profile:TheprofileoptionsarenotapplicabletolocalVMgroups.Only
distributedVMgroupsmayuseVMprofiles(see“VMProfiles”onpage 282).
 stg:ThegroupmaybeassignedtoaSpanning‐Treegroupforbroadcastloop
control(see“SpanningTreeProtocols”onpage 171).
 tag:EnableVLANtaggingfortheVMgroup.IftheVMgroupcontainsports
whichalsoexistinotherVMgroups , enable tagginginbothVM groups.
 validate:Setvalidatemodeforthegroup.
 vlan:EachVMgroupmusthave auniqueVLANnumber.Thisisrequiredfor
localVMgroups.Ifoneisnotexplicitlyconfigured,theswitchwill
automaticallyassignthenextunconfiguredVLANwhenaVEorportisadded
totheVMgroup.
 vmap:EachVMgroupmayoptionallybeassignedaVLAN‐basedACL(see
“VLANMaps”onpage 291).
 vm:AddVMs.
VMsandotherVEsareprimarilyspecifiedbyMACaddress.Theycanalsobe
specifiedbyUUIDorbytheindexnumberasshowninvariousVMready
informationoutput(see“VMreadyInformationDisplays”onpage 293).
 vport:Addavirtualport.
Addavirtualporttothegroup.
Distributed VM Groups
DistributedVMgroupsallowconfigurationprofilestobesynchronizedbetween
theCN4093andassociatedhypervisorsandVEs.ThisallowsVEconfiguration to
becentralized,andprovidesformorereliableVEmigrationacrosshypervisors.
UsingdistributedVMgroupsrequiresavirtualizationmanagementserver.The
managementserveractsasacentralpointof
accesstoconfigureandmaintain
multiplehypervisorsandtheirVEs(VMs,virtualswitches,andsoon).
TheCN4093mustconnecttoavirtualizationmanagementserverbefore
distributedVMgroupscanbeused.Theswitchusesthisconnectiontocollect
configurationinformationaboutassociatedVEs,andcanalsoautomaticallypush
configurationprofiles
tothevirtualizationmanagementserver,whichinturn
configuresthehypervisorsandVEs.See“VirtualizationManagementServers”on
page 288formoreinformation.
