1. Yes, by default you can reserve up to 75% of a link's bandwidth
2. That 25% is set aside for 'otherwise unclassified' (aka class
class-default) traffic
3. Yes, anything not otherwise guaranteed. The default class gets the
leftovers. If you change the max reserved bandwidth you are sort of
reducing the amount that the default class will get. I do know that some
people will set max-reserve to 100 and then make sure they set aside
bandwidth for the default class in their policy.
That's a personal choice, but IOS tries to make sure that you don't hose
yourself TOO badly. :)

Hi Scott and GS member;
I have a small(but important) doubt in MQC. Even after studying MQC a lot,
(1.)What is the default bandwidth for MQC is it 75% of interface bandwidth.
(2.)Say the interface bandwidth is 100MB,is it only 75 MB available for MQC,
In that case is there is any default bandwidth allocated for class default.
(3.)Is there is any default bandwidht for class class-default and is it
75MB(assuming no classes are defined), If any classes are defined, what is
the bandwidith for class class-default (4.)the command
-if)#max-reserve-bandwidth 90, the purpose, is it increases the bandwidth
available for MQC or bandwidth available for class class-default
thanks
Mani

is there a way to mark precedence in cbwfq?
