I built a lab with Intel 6th generation NUC’s with the intent of creating a VMware NSX, vRealize Automation and vSAN learning lab. I ran into a bit of trouble when I was attempting to enable Jumbo Frames on the onboard I219-V ethernet adapter.
I tried setting the MTU using both the gui and esxcli and each time received the following error:
esxcli network vswitch standard set -m 9000 -v vSwitch0
Unable to set MTU to 9000 the following uplinks refused the MTU setting: vmnic0
