For jumbo frames to properly and pass from device to device, both devices plus all network devices in between must be configured. Miss configuration on a single port or device and all of your hard work is for nothing, you will have fragmented packets and may even see a loss in performance.
The easiest way to do this is to run a ping but you can’t just run a normal ping. You must force the buffer size and set it not to fragment. This can be done using the following command below (where 10.10.1.1 is your destination ip):
ping -l 8972 -f 10.10.1.1
