Did you check and see if your MTU is >9000. Word of caution. Make sure that
the network techs can verify the switch can do Jumbo frames. Also ensure
that there is no other piece of equipment between the switch and the GIGi
card.

Subject: Getting Jumbo Frames to work on a p630
What else needs to be done in order to get Jumbo Frames working on a p630.
I'm using a gigabit ethernet adapter of course. I've gone through the
screens to enable Jumbo Frames on the adapter, but a ping with larger than
1500 byte size just hangs. The Cisco switch that I am using has jumbo
frames enabled on the ports. Is there some other setting that needs to
changed other than the obvious ' chdev -l ent4 -a Jumbo_Frames=yes'?
I have a few linux client machines that happily ping large frames between
themselves, its this p630 that I am having difficulty with.
Thanks,
James
