This is an old topic. Has anyone figured out how to enable Jumbo frame support in Workstation or Fusion? In my case, to fully support default configuration of NSX vxlan which normally require 1600 byte frames. One can make NSX work by setting all VDS switch MTU and ESXi VTEP interfaces to 1400, and I have found most apps and VMs work fine. But in some cases, a VM has a problem w/ MTU discovery and fails because it expects 1500 byte frames which can't fit inside the vxlan overlay network. It'd be a lot easier to build NSX labs if Workstation/Fusion supported Jumbo frames which I'm scratching my head on why Workstation/Fusion are missing this.

As far as i know by default it is not supported. Did you edit the nested hosts vmx file and change adapters type (from ethernet*.virtualDev = “e1000” to ethernet*.virtualDev = “vmxnet3”). ? Ensure all the adapters that you are using is vmxnet also follow VMware NSX Lab Part 3 VMware Workstation 11 · rharmonson/richtech Wiki · GitHub
Hi,
I have edited the nested hosts vmx file and change adapters type (from ethernet*.virtualDev = “e1000” to ethernet*.virtualDev = “vmxnet3”) but when i run this command ESX crashes everytime... any recommend tp resolve this issue?
vmkping ++netstack=vxlan <vtep_ip> -s 1572 -d -I vmk3
I'm working with Workstation Pro 14 and the problem still remains. I am assuming amolnjadhav's problem w/ recommended workaround still exists. Anyone? vmware?
Thanks,

Yes, I do face this problem..
