N1kV

  • 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
