[mrtg] Max Bytes, Speed and WithPeak options

[Joshua Krause]

I am graphing my router which can get upto 4 Mbps downlaod and 2 Mbps
upload.  I understand that MRTG graphs on an average but that there is
an option to graph the peaks(WithPeak[_]: wmy).  I have tried this
option and it seems to work.  But the other day my graph showed that i
hit 5.5 Mbps download which on a 4x2 connection is impossible.  Is there
any reason for this happening?  And is there a work around for it?
Could MaxBytes, Max Speed, WithPeak or some other option be used to
correct this?  Here is my cfg to see if i am doing anything wrong...
Thanks in Advance
