  2. This diagram is wrong !
    vsfwd speacks with NSX Manager not with NSX Controler.
    TYPO : it is netcpa not netcpad

    • Thanks for the heads-up.
      Is it possible that I've just mixed up vsfwd and netcpa? It seems to be correct that the ESXi host talks to the Controller Cluster on port 1234/TCP, but its netcpa instead of vsfwd. Also it is the vsfwd that talks to the Manager on 5671/TCP?
