It is a limit of snmp version 1. the 32 bit counter rolls over twice in 5 minutes at ~120mb/seconds > or a know issue and how do I fix it to show > the real speed? switch to snmp version 2c or snmp version 3. These versions support 64 bit counters, which rollover about 1 four-millionth less frequently, making those versions entirely appropriate for speeds up to about a petabit per second. snmpv2 can be set very simply. Please read http://oss.oetiker.ch/mrtg/doc/cfgmaker.en.html for complete instructions. snmpv3 is a little more challenging to configure, but provides cryptographic integrity. Once you get templates set up for snmpv3, the operation is pretty straight-forward. -- Daniel J McDonald, CCIE # 2495, CISSP # 78281, CNX www.austinenergy.com _______________________________________________ mrtg mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
