I've been keeping my eyes open on this topic for quite some time, and
not just with groupstudy but with many resources. The best I've come up
with is that there is no strict answer. The recommendation that I've
gotten most and follow myself is that you should not modify the
max-bandwidth. In terms of your rounding question, I do "what makes
sense". In other words, I don't round 1 to 0, etc.. But do make it all
equal out to 100%. If I were in a lab situation, I'd bug the proctor on
such a question, particularly the rounding.
Here is a document where Cisco references fiddling with the
max-bandwidth that makes sense.

I could see making it 100% if you are absolutely controlling every bit
of traffic on the link and nothing goes default, which is extermemly
unlikely.
Sorry for the lack of clarity but that's my take. Do what makes sense
and is required. If Cisco wants to test my knowledge of the
max-bandwidth command, I'm really hoping to see something like "you
would like increase the reservable bandwidth on this connection by an
additional 10%" or whatever.
I'd appreciate any feedback as well. Feel free to shoot me down; I'll
love you for it :)

Hey, Group,
I was looking through old postings and came across this one. When you
convert these byte counts to bw's under CBWFQ, do you round up or down
on the BW? If you have the max-reserved-bandwidth set to 100, 75,
80(doesn't really matter, I guess) and the total bw rounded up with each
statement doesn't exceed the total BW, is this ok, or should I round
down? Is there a rule of thumb to follow? I can't find this
explanation anywhere on CCO.
Thanks,
Danny

Just add the byte counts together and divide each value by the total.
This gives you bandwidth percentages for each protocol. Then make
class-maps matching each protocol. Create a policy-map and enter the
classes with the appropriate bandwidth percentages. Also don't forget
the queue depth of 100 packets. Then of course apply the policy-map to
an interface with the service-policy [input | output] command.

Hello Group,
I have already posted a question on this topic, but no answers
yet... so posting again...
I want to convert the below Custom Queue to CBWFQ. How can I do
it. Please put your suggestions.
queue-list 1 protocol telnet 0
queue-list 1 protocol ftp 1
queue-list 1 default 2
queue-list 1 queue 0 byte-count 1000 limit 100
queue-list 1 queue 1 byte-count 1000 limit 100
queue-list 1 queue 2 byte-count 2000 limit 100
int s0
custom-queue-list 1
Warm regards
Scot
