mmmh,
"distribute the remaining bandwidth among the remaining traffic"
I
didn't read it under that note before...that may sound like WFQ, but I wonder
if it only means to let all the other traffic go to the default class and we
are over reading the question. It doesn't say distribute *fairly* the
remaining bandwidth (which would be a clear hint to WFQ).
But, neverless
this is a good doubt to have and an appropriate question for the proctor.

RE: max-reserved-bandwidth?
Right... I think I'm getting it. I definitely had
misinterpretations of
the max-reserved-bandwidth command! I actually thought
for some odd
reason that the maximum bandwidth available was 75% unless
max-reserved
was entered - in hindsight that was a little silly of me!
On
the note of "rest of traffic", if you were asked in the exam to
distribute the
remaining bandwidth among the remaining traffic, would
you employ a queuing
strategy for class-default (such as fair-queuing),
or would you use FIFO? If
the exam doesn't stipulate either way, is
there a preference?

You have at least to set max-reserved-bandwidth to 90% (20 + 40 + 30),
otherwise you won't be able to apply the policy map on the interface.
The 10%
will be left for overhead and rest of traffic.

Hey Guys,
I have a question - I searched the
archives and found a similar
reference, however I wasn't satisfied that the
answer was definitively
defined.
If a question in the lab asks us to use
CBWFQ in such a way as to
provide the following bandwidth allocations:
Class
A : 20%
Class B : 40%
Class C : 30%
Then, distribute the remaining bandwidth
among other classes, do we need
to modify the max-reserved-bandwidth? I tried
this in my home lab and
received an error relating to the bandwidth available
(which, by
default, is 75%).
What does everyone think? When would we need to
change
max-reserved-bandwidth?
Alex
