I monitor Perfomance for a Large Network. We noticed that an ATM Subinterface has been dropping around 30,000 Packets per hour. We looked at the higher level Links and they are running clean with low utilization. The Util on the Sub interface is running low as well. QOS is not running and the router appears to be configured correctly. What else would cause the Dropped packets on this ATM interface?
I have this problem too.
