William,
I understand and agree with Tom's calculations. Where does the
"bandwidth remaining percent" command come into place? I know that the
class-default takes its bandwidth from the reserved 25% of interface
bandwidth, so are you saying that the "bandwidth remaining percent" command
adjust the interfaces reserved bandwidth?
Thanks,
Alsontra
