The trick is setting the boot time options on the client. The server side (TFTP server) is the easy part as it's already setup and running. But if the client boots and it's not jumbo frame enabled, TFTP will surely hang on getting the PXEboot as the server will be trying to send 9K UDP frames to a client that's probably defaulted to 1500. If there is a DHCP option to set the client MTU, I've not found it anywhere. -- Robert Blayzor INOC, LLC rblay...@inoc.net http://www.inoc.net/~rblayzor/ _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
