First let me start by saying I'm in no way an expert in this field. We have a 7206 router that continues to increment input errors, crc errors, line errors, etc. We have worked with our DS3 provider and they can't see any errors. They have monitored and done intrusive testing (hard loop). They do however say they can see errors coming from our end. The only place we are seeing any errors is on the serial interface. To add it happens sporadically. To my knowledge if they are input errors, aren?t those caused by what coming into the router? Making this the ISP's problem to fix. Or is this a configuration problem? Any help is greatly appreciated.
Attached is what we saw this weekend.
