James,
Check also the following:
tcp_sendspace mine are setup to 131072
tcp_recvspace also setup to 131072
rfc1323 my server setup to 1
In my case all this preparation did not work because after asking the
network group about the switch it end up they had another piece of equipment
in between that would not support Jumbo frames.
Hope it works for you. Good Luck.

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
