[mrtg] mrtg on d-link DI-524

You can see in your walk, that it is returning a speed (or what mrtg will
use as MaxBytes) as zero.
IF-MIB::ifSpeed.1 = Gauge32: 0

Take out the "#" and change the 0 in MaxBytes to the equivelant of what it
is 10, 100 or 1000 as a max. 100 Fast Ethernet is 12500000 I think so divide
or multiply by 10 or as is, depending on what that interface is.

Subject: [mrtg] mrtg on d-link DI-524


I'm tring to monitor my router a d-link DI-524 with mrtg, i've used cfgmaker
with this options:

cfgmaker --global "WorkDir: /home/orizon/public_html/mrtg/" --global
"Options[_]: bits,growright" --output /home/orizon/public_html/mrtg.cfg
cbrouter at 192.168.0.1

but this is the output of the configuration file: 

# Created by 
# /usr/bin/cfgmaker --global "WorkDir: /home/orizon/public_html/mrtg/"
--global "Options[_]: bits,growright" --output
/home/orizon/public_html/mrtg.cfg cbrouter at 192.168.0.1


### Global Config Options

#  for UNIX
# WorkDir: /home/http/mrtg

#  or for NT
# WorkDir: c:\mrtgdata

### Global Defaults

#  to get bits instead of bytes and graphs growing to the right
# Options[_]: growright, bits

EnableIPv6: no
WorkDir: /home/orizon/public_html/mrtg/
Options[_]: bits,growright

the cfgmaker script comments my configuration because: 

### The following interface is commented out because:
### * has a speed of 0 which makes no sense

But surely my router is not at zero speed, i'm in a lan with 4 computers. I
guess i'm missing something...

This is the response of my router (model D-link DI-524) when i call an
snmpwalk:

SNMPv2-MIB::sysDescr.0 = STRING: Internet Gateway Device

IF-MIB::ifOutQLen.1 = Gauge32: 16
IF-MIB::ifSpecific.1 = OID: SNMPv2-SMI::zeroDotZero
End of MIB

i'm quite a noob with snmp, so what i'm doing wrong ?
