Ever try configuring the bandwidth statement on the interface to a higher
number. This doesn't affect the circuit speed as that is derived from the
clocking on the line but changing the bandwidth statement will affect
routing protocols, queuing, rsvp and the like.
Just an idea.

Subject: Re: Custom Queuing byte count calculation
Not to throw a monkey wrench into this whole thing, but now extrapolate this
and add a default que under the custom queue..... I will save you the
research and tell you that the byte limit by default is 1500 for all queues.
So you can still do your math, but by default, you can only reserve 75% of
the total bandwidth available by default. So to convert over to say CBWFQ
there is probably some additional math due to the 75% unless you use the
interface command maximim-reserved-bandwidth....
Now say your total bandwidth on the link is 128k.........
The equation is this.

While I have gathered all these facts, I am still missing something.
Because
when I apply that formula and stick in 128k for the bandwidth capacity, my
bandwidth percent will always add up to 126 (rounding down) when I add up
all
the queues.
In CBWFQ, you can not enter %'s to equal higher than 100%.......
So I am still stuck...
