RE: [swinog] Cablecom Routing/Peering changes?
duplex problems on switch? let fredy check what results he gets when he pings cablecom directly... -steven -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Kellenberger Sent: Tuesday, March 07, 2006 9:25 AM To: swinog@swinog.ch Subject: [swinog] Cablecom Routing/Peering changes? Hi all Our office is connected via VPN through Cablecom Highspeed (62.2.230.80) to Init7 (82.197.163.110). Last Thursday, we had a short interruption and since then throughput is really bad. Fredy Kuenzler said, the interruption was due to peering changes of Cablecom to Init7. I'm trying to find out where the problem is, maybe someone here can help me out.

We recently moved traffic from Init7 to Cablecom over TIX-2. Regards, Fredy ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog

Glogger Steven schrieb: problem is fixed. tix-2 was on speed auto/duplex auto. BTW this is a common issue. If you happen to run some Cisco 29xx|35xx switches, check duplex problems with entering #sh int | inc CRC or #sh int | inc error if it shows more than just a couple of errors, then you most likely have a duplex / speed mismatch. Rule of thumb: - Cisco Switch - any Switch: usually set to Speed 100 / Full Duplex - Cisco Switch - Cisco Router: always set both sides to Speed 100 / Full Duplex - Cisco Switch - Host: usually better to use Speed auto / Duplex auto So don't be surprised if you have bad performance with Duplex mismatch. Another possibility is to check the LED status of the Ciscos - if you see yellow blinking (instead of green), then something is wrong.
