You really don't need to do anything... Anything that isnt spoken for in your 
service-policy that is applied to the interface is going to fall under the 
class-default as a catch all.


The % of BW is up to you... The default is 75% of the link and will depend what 
you want! 


If you do max-reserved BW of 90%, the values will be adjusted as such: 


20% of 90% of the link...

A question regarding QoS:
 
Confugure  QoS to corresponding interface. Subscriber’s ip address and
bandwidth are as follows :
· SUB_1 : 100.100.0/24 bandwidth  20%
· SUB_2 : 100.100. 2.0/24 bandwidth  30%
· Voice : Critical voice traffic bandwidth 40%
· Class-default : Class-default for remaining bandwidth
 
 
I just need to ask what bandwidth I allocate to  Class-Default ? Should I just 
assign it as  fair-queue or need to assign bandwidth of 10 % which is the 
remaining bandwidth
 
under policy map:
 
policy-map CBWFQ
class class-default 
bandwidth percent 10
 
or
 
policy-map CBWFQ
class class-default 
fair-queue
 
and what % bandwidth I need to allocate to the interface

 
Interface X 
max-reserved-bandwidth 90
 
or 
 
Interface X 
max-reserved-bandwidth 100
 
 
Plz assist
 
Thanks
