Have a point to point leased T1 line from NY to Florida - Cisco 3600 in NYC and a 2600 in Fl. It is taking input and CRC errors at both ends. Had the telco run a 2 hour stress test last night and they state the circuit is clean. I am not seeing any packet loss or latency, just the errors themselves. I can post configs or stats for either router if someone could help me out or advise me what else I might check. Last week someone on this site helped me get the clocking set correctly as I was getting slip secs - that corected the issue at my other location that is connected to NYC...but not the Florida location - after monitoring I still see CRC and input errors. They seem to be accruing more rapidly in the NY 3600 as opposed to the Fl 2600.
