I have read a lot of Cisco books, including CLSC. Cisco recommends that you do not use auto-select. By definition, when you get FCS errors, that means the card must have gone to FULL mode. If there were collisions, then it went to half. I would hard coat which ever mode you know you need and you should be fine. Also check out the catalyst pages and that will help immensely. >From: Oscar Ricardo Silva <oscars@mail.utexas.edu> >To: freebsd-questions@freebsd.org, Reinoud.Koornstra@ibb.net >Subject: Re: 3com cards and cisco 1900 catalists >Date: Wed, 02 Aug 2000 07:41:31 -0500 >MIME-Version: 1.0 >Received: from [204.216.27.18] by hotmail.com (3.2) with ESMTP id >MHotMailBB5161B90095D82197A7CCD81B12747B0; Wed Aug 02 05:40:30 2000 >Received: by hub.freebsd.org (Postfix, from userid 538)id 5C42937B7E3; Wed, > 2 Aug 2000 05:40:02 -0700 (PDT) >Received: from localhost (localhost [127.0.0.1])by hub.freebsd.org >(Postfix) with SMTPid 273C02E8190; Wed, 2 Aug 2000 05:40:02 -0700 >(PDT)(envelope-from owner-freebsd-questions) >Received: by hub.freebsd.org (bulk_mailer v1.12); Wed, 2 Aug 2000 05:40:01 >-0700 >Received: from mail.utexas.edu (wb3-a.mail.utexas.edu [128.83.126.138])by >hub.freebsd.org (Postfix) with SMTP id BE74137B5C1for ><freebsd-questions@freebsd.org>; Wed, 2 Aug 2000 05:39:57 -0700 >(PDT)(envelope-from oscars@mail.utexas.edu) >Received: (qmail 6506 invoked by uid 0); 2 Aug 2000 12:39:50 -0000 >Received: from dhcp-199-210.dsl.utexas.edu (HELO >osilva-home.mail.utexas.edu) (128.83.199.210) by umbs-smtp-3 with SMTP; 2 >Aug 2000 12:39:50 -0000 >From owner-freebsd-questions@FreeBSD.ORG Wed Aug 02 05:42:11 2000 >Delivered-To: freebsd-questions@freebsd.org >Message-Id: <4.3.2.7.2.20000802073900.00af0600@mail.utexas.edu> >X-Sender: oscars@mail.utexas.edu >X-Mailer: QUALCOMM Windows Eudora Version 4.3.2 >In-Reply-To: <Pine.LNX.3.95.1000802082345.14534A-100000@ux1.ibb.net> >Sender: owner-freebsd-questions@FreeBSD.ORG >X-Loop: FreeBSD.ORG >Precedence: bulk > >Sounds like a duplex mismatch issue to me.
