[mrtg] Re: Cisco Sub interface problem...

[Kruepke]

Are you reaching the MaxBytes value for that target in your config file?  The MaxBytes value is a based on the recognized bandwidth of the interface (set with the 'bandwidth' interface configuration command or defaulted) and has nothing to do with the actual bandwidth.  It could be lower than it should be for the problem interface(s).

Check your config file setting for MaxBytes (this is also the value used to calculate your %utilization) and the docs on MaxBytes and AbsMax.

>From  the interface itself, when you do show on the interface rather than sub interface you are able to see the actual utilization....i.e. I try to graph 2/0/0.1 and 2/0/0 both are different and there is only one sub interface....

Maybe you've reached the maximum transmission speed of that link.  How do
know that your utilization has exceeded 512K?  Many times MRTG tells us
EXACTLY what is going on even though our perception is otherwise.
