[mrtg] Re: Inwards traffic not correct

[Paul C. Williamson]

Have you tried:

Clearing the counters?
Checking what protocols are flying through the interface?

I would bet one of these will give you some clues.

Hi Tyler,

That amount traffic definably is not correct. There is no one using the
link at the moment, and it's only an ADSL line 1024/256. So it can never
ever produce these kind of figures (I which it could though :)

The router is connected to a switch, so it will only see broadcast
traffic.
I'm monitoring broadcast at another machine and there is nothing. (at
least
not 1.5MB worth of traffic :)

I'll try that later on.... But I doubt this will give me clue.

Thanks,
