Apart from setting the MTU on the Physical/vSwitch/PortGroup, we have to set the MTU on the Guest Os level right.? So, I am looking for some sort of setting to make the MTU of the vNIc to 9000 from the ESXi layer rather than changing the value in the guest operating system.
As noted, the MTU setting on the portgroup is only as a maximum allowed frame size at the vSwitch level, but is invisible both to the physical switches and the guest operating systems. There are no standard way to negotiate the maximum frame size at layer two (but is done on layer four within each TCP session, but that is something else.)
