This is a pretty wild guess, but can you verify that the ethernet settings are correct? If the interface is set to autoneg, can you verify that both ends (the FreeBSD machine and the switch itself) have negotiated the same speed/duplex? Wouldn't be the first time I saw a switch negotiate a different speed/ duplex than the NIC on the other end. -- Bill Moran http://www.potentialtech.com _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
