Thanks ED for the reply we as i mention I already have apply 1min patch
and I am Collecting Data after ever Minute with snmpv2, And what I
think SNMPv2 uses 64-bit values counters and my Router supports snmpv1,
v2 & v3.<br>
<br>Any solutions.<br><br>TheONe Kan<br><br><div class="gmail_quote">On Sun, Jun 21, 2009 at 9:03 PM, Ed LaFrance <span dir="ltr"><<a href="mailto:edl@colocationonline.info">edl@colocationonline.info</a>></span> wrote:<br>

Dear ALL,<br>
<br>
I Am facing a strange problem, As I have attached a png file of my WAN GIGA Interface of my Zyxel Router, Problem is that when ever our Internet Bandwidth cross over 555 Mbits/s MRTG creates False Graphs, but on real time monitoring Show more then 600 Mbits/s of data flowing normally thought it, I am using SNMP v2 to create MRTG , also have applied 1min MRTG patch to create MRTG. I have CHeck router cpu and memory and other Interfaces are working normally and there MRTG matched the real time flow.<br>
<br>
Hope for a cool advice from you guys.<br>
<br>
Thanks in Advance,<br>
<br>
KIndest Regards.e<br>

This is typically the byproduct of multiple counter rollovers between data samples. What is your sample interval, and does your router return 64-bit values for the octet counters? Those are the things you should start with. If your sample is already down to 1 minute (I think that is what you said above), then almost certainly the issue is 32-bit counter values, in which case you are SOL with this approach.<br>
