[mrtg] Re: MRTG and cablemodem problem

[Alejandro]

Jason, thanks for your help. I tell you my ethernet device connected to 
Internet (eth0) is 3Com and I try to setup mrtg and snmp several times 
and always I get a greater bitrate than I have. Also I check the real 
time bitrate using the iptraf package and I notice that the device speed 
is lower than 128 Kbps (that's OK) and MRTG shows me speeds around 400 
Kbps and up (???).

So what can be the problem ??? Maybe a snmp problem ??

I appreciate your help, regards !!!

Alejandro
