Dear Sir,
I am using SNMPv2. Configuration of the link is as follows:-
Target[routers]: 1:[EMAIL PROTECTED]:::::2 + 2:[EMAIL PROTECTED]:::::2
+ 3:[EMAIL PROTECTED]:::::2
MaxBytes[routers]: 125000000
Title[routers]: Total Speed for the Routers
But it shows the traffic only upto 1 Gb. Whereas traffic of my link is more
than 1Gb.
So, plz help me. can you have any idea that how can i use SNMP v3.
Thanks & Regards
Reena

Its in the FAQ. You need to use SNMPv2 or SNMPv3 because SNMPv1 only
uses 16bit counters, which roll over in the polling window if you have 1Gb
traffic. See the MRTG manual for how to specify SNMPv2 you add :::::2 to
the end of the Target definition.

Subject: Re: [mrtg] traffic not showing more than 930mbps on the link
Dear all,
Thanks Eric, Thanks Daniel . Now its working properly with snmp v2 .
problem was in MaxBytes setting. By MaxBytes setting 125000000 i can get
traffic upto 1000 megabits.
MaxBytes[routers]: 125000000
One thing more, we can aggregate more than 5 interfaces.
Now can anybody suggest me how to get more than 1000 megabits traffic on
the link? Is it only depend on MaxBytes setting or i have to do some more
configuration. what will be MaxBytes setting?
Thanks in advance

Reena,
In addition to what Daniel stated I jut wanted to add - Are you sure
the MaxBytes setting is correct? 125000000 is only 1000 megabits or
depending on how your conversion (kibi vs kilo) 953 megabits.
