My lab is running:

  • ESXi, 6.5.0, 4887370
  • OFED
  • ConnectX-2 MHQH29C with 2.9.1000
  • IS5035 switch with subnet manager

I followed the instructions here: 10Gb SFP+ single port = cheaper than dirt

I am able to get IPoIB working and all of the hosts can ping each other.

However, multicast is not working. How can I get multicast to work? It is preventing vSAN from working.


Strictly speaking this doesn't answer your question... but if you're already running 6.5 build 4887370 (6.5a?) why don't you update to 6.5d (VSAN 6.6) or higher and say "Goodbye Multicast"?
