I'm thinking counter wrap due to a 32-bit counter. A 32-bit counter will wrap (reach the maximum and start over from 0) after the number exceeds 2^32. MRTG can handle it if it happens only once, but in a 60-second cycle it will happen more often if the rate is high enough. I think you're exceeding that rate and so the counter is resetting to 0 twice during each polling cycle. If I'm right then the remedy is to use 64-bit counters when polling interfaces faster that Fast Ethernet. _______________________________________________ mrtg mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
