We have a 2600 Router that uses ATM and is connected via T1 line to a Fore ASX1200 at our main site.
We experience terrible slowdowns during the day and downloads will often time out. We've tried unplugging everything and just plugging the router into a switch with one PC. We still have the same problem.
When I did a 'show interfaces' the other day, I noticed the ATM interface had 260,000 CRC errors. The last time it had been reboot was 8 weeks ago. That seemed like too many to me.
Can someone point me in the proper direction for troubleshooting this? I've attached some outputs from show commands as well as the running config. I've cleared the CRC Counters, that's why they're not high in the text files.
Any help is greatly appreciated.
