Hey welcome to the communities,
what workstation version are you using? A Workstation 7 performance guide states that workstation doesn't support jumbo frames. I can't find anything for newer releases, but I'd assume, that the Workstation still only supports the standard 1500 MTU.
Edit: I've moved your thread, as this doesn't seem to be a storage problem.
Thanks for the reply, I use workstation 10 !
Please try changing the type of adapter to vmxnet3.
(i.e. edit .vmx and set ethernet0.virtualDev = "e1000")
Internet Public Knowledge Advisor (a.k.a. google) reports that jumbo frames are not supported,
but if you change the default (e1000) net type to vmxnet3, it does work.
I run into this while trying to setup an NSX lab on workstation and finding out that MTU 1600 (needed by NSX for vxlans) was not working...
FTR, it seems there's a reason for not being supported.
After changing the device type to vmxnet3, VMs can indeed use jumbo frames and they work, but bridging to the physical network is another story.
Interestingly, bridging TO the network (including the host) seems to work, but FROM the network does not.
And this kind of breaks console streaming
I'm facing the same issue when setting up a lab for NSX.
Tried with Workstation 10 and did not work despite I was using a vmxnet3 adapter.
Did you use a Host-only network for the VXLAN transport ?
Did you connect a host virtual adapter to the VMNET (ex: VMNet1) network used for the VXLAN transport ?
Using Workstation 10 and 11, I successfully test VTEP connectivity between ESXi nested host with MTU = 1500
but when I test VTEP connectivity between ESXi nested host with MTU > 1500
the ESXi crashes with the following exception.
I did get the NSX lab to work, sort of.
Internal only works AFAIK, and from the outside world works up to MTU 1570 if memory serves. That breaks the standard test of MTU 1600 but works for some setups. In the end, it was so complicated that I ended up shifting my NSX test bed to a real ESXi and using nested. That's another can of worms, but works
The only think that comes to mind is that you might need MTU set in the physical adapter too.
