If you use jumbo frames without VLANs, then ALL hosts must support jumbo frames (and I think would also have to be gigabit ethernet connected since jumbo frames weren't supported in 802.3...although I'm assuming that the gigabit spec allows for jumbo frames, which may be a bad assumption on my part). -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
