The problem is that the 32 bit counters wrap. See RFC 2233 for very clear detailed information. The mib variables specified in RFC 2233 require Snmpv2c to read the 64 bit counters.
Now there is one question I have for mrtg and rrdtool experts. How is the arithmetic done for the 64 bit counters? Is it done as 64 bit unsigned arithmetic, or 32 bit floating point? If it is done as 32 arithmetic, precision is lost.

Dear all: I have one problem about graphing SNMP traffic of CISCO GSR when the traffic was higher than 10x M bits/s. Someone tells me MRTG has the same problem and it can be resolved by change the SNMP version to 2. However, it did not work for my perl program. Does anyone know what is wrong ? Thanks for help!
