- components
- virtual supervisor module (VSM): modules 1, 2
- virtual ethernet module (VEM): modules 3+, mark control traffic with CoS = 6
- replaces vDS in vCenter (up to 6.5)
- replaced by AVE in ACI, no standalone replacement
- port-profile instead of interfaces
- assigned to VM or ports
- live templates
- vTracker – fetch VM information
- VMware, Hyper-V, KVM
- eVXLAN (enhanced VXLAN)
- unicast
- distributes mapping across VSM
- no unknown unicast flooding
- no head-end replication for bcast, mcast
- incompatible with CoPP, FCoE (requires separate HBA)
- only CoS-to-queue mapping ⇒ DSCP and CoS are to be set on ingress
