Did you configure it to 100MBit, full-duplex? ------- Yes, I configured everything (all eight interfaces: four on FreeBSD and one= on each of the routers) to be 100baseTX and full-duplex. As a test, I left out the 'media' and 'mediaopt' portions of the interface = definitions in rc.conf and all the interfaces came up but three were in hal= f-duplex mode, I think em0 was full-duplex (I am not in the lab to check). I have heard horror stories about Ethernet auto sensing, so I make sure the= Cisco routers and FreeBSD specify 100 Mbps and full-duplex. I begin to won= der if even that is safe. :-( [ why does Outlook not quote properly ]
