I can’t figure out how to adjust the MTU on the management vmk0. I was able to adjust the MTU on vswitch0 but vmkping -s 8972 -d {ip of other host} failed.
Using the vSphere Client I went to the Host, Configuration, Networking, properties of vSwitch0 (confirmed the vSwitch has a MTU of 9000), selected “Management Network”, clicked edit, and in NIC Settings changed the MTU to 9000.
