The MTU setting on vDS level only allows Jumbo Frames to pass (like on any physical switch). As long as your VMs do not send jumbo frames, vSphere won't do it either (for VM traffic). Like written above, you cannot set different MTU values on portgroups, this will only work on vmkernel ports.

So in conclusion: if you want to use jumbo frames you have to do the following things:

- Check (and enable) your physical switch to allow jumbo frames

- Modify the MTU on vDS

- Modify your VM (on OS Level) to send jumbo frames
