Hi there,

One of our servers is a RH7.3 box with an intel gigabit network card. It worked fine connected to an Intel gigabit switch. Unfortunately the switch failed and the company now has a policy of buying Cisco (God only knows why). The network card will not work at all with the new switch. So the server is connected into one of the 100base-T switches where it works fine for a couple of hours then the network goes off line again. Restart the network and it stays up for a few seconds.

I had none of these problems until the Cisco switch was added to the network. Is there some weird Cisco protocol that may be causing this? I need some information for the support Nazis here (I am of course locked out of the switch).

Thanks for any help

Paul

Ah, I swear I just saw something about this on the screensavers.. lol
Um.. I think what they said was that.. for some insane and really stupid reason, some brands were now shipping with... something for the Ip address set by default, and it needs to be unset for everything to work properly.
Sorry I'm so vague, it was on a month ago..

What is the screensavers? Is it a website that I can go and search?

As to the ip address thing, the support Nazis have configured the switch and god only knows what they set to what. They are rather sercretive about their setting. I have checked that they did not set the switch IP to the same one as the server!

Thanks

Paul

Its a tv show. And, the story was a while ago so a search wont help anynmore. To much net clutter

Yes I must admit I am also not a Cisco fan. There are none problems with Cisco switches based on some custom routing protocols that cisco uses. The problem is apparently is more predominant with 3com products. Supposedly there is a way to turn them off and make the switch use standard protocols but if you have no access to the switch you are S.O.L.

Is spanningtree running on the Cisco switch? Have you hard coded the speed settings on the Server NIC? Have you configured that port on the switch for "Uplinkfast"? What troubleshooting have you done so we can eliminate redundancy?

regards...

Paul is correct there are things you can do to the Linux box. Sorry to mislead you. It's easier in my opinion to turn it off of the switch because I'm not very proficient with Linux. Good but not great. I know we had trouble with ours and were able to solve it with things like hardcoding netcard speed. autonegotiation was failing along with other things.
