[mrtg] mrtg and fritzbox with ds-mod

[Bernd Schröder]

Guten Tag mrtg mrtg,

i'm  using  an  AVM  Fritzbox as DSL-router. The firmware was modified
with  ds-mod, so now i've got running net-snmp 5.1.2 on my box. I want
a snmpd for traffic-measure with MRTG.

But  MRTG  show's me a completly crasy graph for the incoming traffic.
Interface 14 (see below in the conf) is correct.

You can see the graph at http://olav.homelinux.com/sys-infos/mrtg/fritzbox.html

Where's my fault?


Here is the part of mc /etc/mrtg.conf:

Title[fritzbox]: Fritz!Box
PageTop[fritzbox]: <H1>Statistik des Netzwerkverkehrs (DSL-Router, Fritz!Box)</H1>
Target[fritzbox]: 14:doedel at ds9

The router (aka ds9) answers correct values (it looked so the me):
