Windows 2012 Server - NIC Teaming for HyperV

  • Article

If you are using HyperV on Windows 2012 which is configured with a teamed network (For HyperV Data), few settings with specific to teaming.
Chose Switch Independent mode as the teaming mode - where switches are not aware that different interfaces on the server comprise a team. Instead, all the teaming logic is done exclusively on the server.

Chose "Hyper-V Port" as the load balancing mode.
This is a perfect configuration where everything work as expected.

If you configure teaming with Address hash load balancing mode, you may end up in the below issues.

  • From Virtual machines, access to internet sites will not work
  • From Virtual machines, Will be able to ping an ip, telnet to RDP port 3389 of that ip, but cannnot connect the remote desktop through RDP
  • At the same time, BING works fine and you will be able to perform search on BING
  • Access to this virtual machine through RDP will be fine
  • PING to this virtual machine will be fine

Good luck
