This is for a Cisco 3662 running IOS 12.2
I have a number of T1's that are all being routed back into the network via this 3660. All the T1's are point to point and traverse using serial interfaces and now a few of them are acting strange.
Ever 20-30 minutes, for 3-4 minutes all connectivity is lost. And while it is not consistent enough to plan for the outages, it happens most of the day, every day.
My question is that to start troubleshooting the problem, I need to see what is happening on the interface before I call the T1 company. How do I reset the interface counter back to 0 so that I can log any activity that occurs on that interface over a period of time and is there a way to log that into a file that I can ftp out?
