At Best, we had to force duplex and speed on both our Catalysts and our BSD boxes, otherwise, mysterious problems would occur (slow transfer rates in one direction, input or output errors, etc.). I'm sure Matt Dillon can attest to this as well. I highly doubt it's specific to the xl driver, or even 3Com cards, since 4-5 months ago I had such issues connecting a Catalyst to an HP ProCurve switch -- again, had to force the speed and duplex on both ends. I think this is a pretty "historic" problem with Cisco equipment. Look around the Web and you'll see what I mean. The procedure, if I remember right: Cat> set port x/y speed 100 Cat> set port x/y duplex full Cat> set port disable x/y BSD> ifconfig xl0 ... media 100baseTX mediaopt full-duplex BSD> [see note] Cat> set port enable x/y NOTE: Occasionally I'd also see this procedure fail until the BSD box was actually *rebooted*. This problem always eluded me, but may have changed severely since the days of 2.2.8 ( :) ). -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977. | On Tue, Sep 07, 2004 at 11:36:57AM -0400, Brandon S.
