In article <local.mail.freebsd-stable/Pine.BSF.4.21.0105022007170.476-100000@joliet.groenquist.com> you write: >The errors I received were the classic errors which denote that there is a >negotiation mismatch between the card and the switch. I had the card set to >auto-negotiate (the default for the fxp driver); the switch was hard-set to >full-duplex 100Mb. The errors were "FCE" errors, and the symptom was >rediculously poor performance (20KB/sec). Once I set both card and switch >port to full-duplex 100Mb, the errors disappeared and I was able to get >"normal" performance (which for me is around 5-6MB/sec. average). Autonegotiate generally only works if *both* sides are participating. If one side is wired down, it typically means that it is not advertising what the device is capable of, and the other end will get it wrong unless it is also wired down as well. -- Jonathan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
