If I am counting the zeros properly, this is gigabit, but you are using the 32bit snmp counters instead of the 64 bit counters. So, every time you go above ~130 MB/s mrtg will give you bizarre results, since it will roll over twice in 5 minutes. Switch to snmp V2 (or v3, if you prefer to have the polling encrypted) and it should work fine. -- Daniel J McDonald, CCIE # 2495, CISSP # 78281, CNX Austin Energy http://www.austinenergy.com _______________________________________________ mrtg mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
