What version (possibly versions) of code are you running on your various Cisco devices?
Are you using SNMP v1 or v2 to poll the devices? If you are using v1, and the counters are exceeding the 32 bit max, if the IOS or CatOS supports it, you can goto SNMP V2 to give you 64 bit counters (any one feel free to correct me if I'm wrong about this) to give you a better view of the interface.

This is becoming a big problem for us, as we have just implemented a new NMS which clears all counters once per day. I know this is an issue of the OID counter wrapping, leading MRTG to think that a massive bandwidth spike has indeed occurred, but is there a way to configure MRTG not to draw this conclusion (and alleviate all of the massive spikes in our graphs)? Does a newer version of MRTG handle this differently? I have looked high and low, but can't seem to find an answer on this. Thanks in advance...
