Cisco switches in the 2900 series (2924XL, 2948G3), and the Catalyst 6500 series have a common issue where they'll autonegotiate the wrong DUPLEX, which leads to slow communications speeds, and eventual erroring out. (I don't blame this on the switch, it's just the best and most logical place to concentrate all your 'hard settings'). Make sure you've got full duplex on each side (from the switch's perspective and the client NIC). I ALWAYS force the issue, with the "speed 100" and "duplex full" commands, directly on the switch, and only change from that when required (ie a 10baseT device). It is always a poor idea leave too many things in "auto configure", be they switch ports, ip address assignments, budget variances, employer relations, choices for lunch, coffee vendors, etc. -- Ted Deppner http://www.psyber.com/~ted/

Re: Auto 10/100Mb card fallback from 100 to 10 on 100Mb network
I would happily try another ethernet card if that would solve the problem. But somehow, since I've tried a few cards ( i admit they are the same model, but one was a fresh new out-of-the-box card), I don't think another ethernet card it the solution. The strangest thing is that it auto falls back RIGHT when the networking code in debian loads up, not when the box boots, not when the kernel loads the realtek code, but exactly when debian loads up networking stuff. Now why would that be? Could anything there cause this?

I would happily try another ethernet card if that would solve the problem. But somehow, since I've tried a few cards ( i admit they are the same model, but one was a fresh new out-of-the-box card), I don't think another ethernet card it the solution. The strangest thing is that it auto falls back RIGHT when the networking code in debian loads up, not when the box boots, not when the kernel loads the realtek code, but exactly when debian loads up networking stuff. Now why would that be? Could anything there cause this?

RE: Auto 10/100Mb card fallback from 100 to 10 on 100Mb network
I suggest you spend 39$ on an Intel eepro100 (z-buy.com, think shipping on those cards is free) and give it a try. I'm betting it will also fail to work in this machine, and you'll discover the problem is physical plant related, but perhaps not. Either way you've tried most other things, may as well shell out a few dollars. After all, it sounds like you've put at least 39$ worth of your time into this, and you haven't been able to eliminate the problem yet. - jsw -Original Message- From: Jason Lim [mailto:[EMAIL PROTECTED] Sent: Sunday, April 15, 2001 4:25 PM To: debian-isp@lists.debian.org Subject: Re: Auto 10/100Mb card fallback from 100 to 10 on 100Mb network Well, here is the stupid and interesting thing.
