Jumbo frame fragmentation

[snyderkv1]

I just enabled Jumbo frames (9000 MTU) from end to end (initiator to target). Two questions.

1) Should I set Jumbo frames everywhere because I don't see why the Management network needs it but if it doesn't hurt why not.

2) I notice some of our sites are set to 1500 on the upstream switches but the port groups are set to 9000. Does this mean there's extra fragmentation on the network?

Thanks again

what size of jumbo frame enable on physical switches? If you enable 1500 MTU then no need to change in vSphere environment as by default set MTU 1500 on each vSwitch. If you set Jumbo frame 1600 or 9000 or respective ports then you need to change MTU on each respective vSwitch in vSphere environment.

Sorry for the confusion or badly written post, I edited it to make more sense.

Thanks guys, I already enabled Jumbo end to end and know what it is and how to set it. But I guess I don't need to enable Jumbo frames on the management vmk which was sorta my question I guess..
