See the manpages for the various devices, for example man em: Support for Jumbo Frames is provided via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility con- figures the adapter to receive and transmit Jumbo Frames.

As for the rest, try: ifconfig_em0=inet x.x.x.x netmask x.x.x.x media 1000baseTX mtu 16114 Robert Huff ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
