The 3550s are very limited with respect to MTU - the standard model can only do up to 1546 byte, while I believe the -12G model can to 2000 byte. In any case - you won't get a 4470 byte packet through a 3550. Also, changing the MTU on the 3550 requires a reboot. Steinar Haug, Nethelp consulting, sth...@nethelp.no
