To enable Jumbo Frames on a vSwitch, change the MTU configuration for that vSwitch.

1

On the vSphere CLI, run the vicfg-vswitch -m MTU vSwitch command.

This command sets the MTU for all physical NICs on that vSwitch. The MTU size should be set to the largest MTU size among all NICs connected to the vSwitch.

2

Run the vicfg-vswitch -l command to display a list of vSwitches on the host, and check that the configuration of the vSwitch is correct.
