[mrtg] Problem loading MIBs

[Utsav Ratti]

I want to monitor some of the modem stats on a Cisco 4500. To that end, I
obtained a modem management MIB from Cisco, but when I try to load it into
MRTG via mrtg.cfg, I get the following error:

C:\mrtg-2.8.3\run>perl c:\mrtg-2.8.3\run\mrtg c:\mrtg-2.8.3\run\mrtg.cfg
Loading C:\mrtg-2.8.3\MIBs\CISCO-MODEM-MGMT-MIB-V1SMI.MIB
cannot encode Object ID .47.1.1.7: first subid too big in Object ID
47.1.1.7 at
c:\mrtg-2.8.3\run\/SNMP_util.pm line 957.
SNMPGET: Failed to reach target:
"cmSystemModemsAvailable&cmSystemModemsUnavaila
ble:public at 157.191.175.11". I tried multiple times!

I have tried both SNMP v2 and v2 in v1 format MIBs, with the same result.
Can anyone explain to me what this means and what a possible remedy might
be? Is this a problem with the SNMP_util.pm that MRTG uses?

Cheers,
Utsav
