Is your utilization around 110 Mbps?  If so, you're probably hitting the
limits of the 32 bit counters, and they are wrapping.  This can usually
be resolved by using the 64 bit (snmp v2) counters, if your device
supports it.

Search for SNMPv2c:

Subject: [mrtg] Graph shows unreal drop in traffic


We are having a very strange problem.

Sometimes we are getting a drop in traffic in the mrtg graphs. But when
we look on the router itself, there is no drop. 

Does anyone knows something about this problem?

Thank you.
