The network we currently boot several diskless machines from has a lot = of NFS traffic and we'd like to enable them all for larger MTU's however = the one thing stopping us is the issue with initial boot seemingly only = supporting an MTU of 1500. =20 I know we can set the MTU later (post boot) on the diskless machines, = but it doesn't seem we can run a higher MTU on the TFTP server as we'd = have TFTP UDP traffic with mis-matched frame sizes at that point.=20 --=20 Robert Blayzor INOC, LLC rblayzor@inoc.net http://www.inoc.net/~rblayzor/
