Ok so you're saying that locking the media type to 100baseTX will disable autonegotiation for duplex. I was considering speed and duplex to be independent.

(But it might be what he meant.) I took it to mean: "Hard-configuring the other end will stop the other end from sending negotiation information. If that happens, the fxp device will receive no information from the other end and will not be able to make an informed decision. In this case fxp defaults to half-duplex." -Mitch To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
