With all the talk of "Next Generation" networks and such, I wonder, what's the largest MTU allowed by your hardware? I have found some of my kit incapable of even the 9k "jumbograms" as belittled here:

Who out there allows larger MTUs?
Joe St Sauver collects a list of hardware MTUs. http://darkwing.uoregon.edu/~joe/jumbo-clean-gear.html which is linked off Matt Mathis' page above. He also did a really cool survey of MTU 'bottlenecks' on the Internet2 http://darkwing.uoregon.edu/~joe/jumbos/jumbo-frames.pdf presented at an Internet2/NLANR Joint Techs meeting in Feb 2003 If nznoggers have experience with hardware that is not on Joe's page, send him an addition on the email address specified at the top of his page.
