The statement is correct but there is a little more to it...
If 100% of the link is being used and each class is using there allocated
amount of BW:
sub1 will get 20%sub2 will get 30%voice will get 40%
and...
Class-Default will get the remaining 10% (Nothing else can touch it, its the
catch all) if it is needed...
Only when the link is NOT operating at 100% will any remaining BW be divided up
so you dont need to allocate anything to class-default but its not going to
hurt if you do.

explanation of how the remaining bandwidth is treated. Also, this is directly
off of the Cisco Website. Based on this, you need to assign the percent to the
default class. “Thus, remaining bandwidth is shared by all bandwidth classes
and class-default.” From: [email protected]

Subject: [OSL | CCIE_RS] QoS Hey Experts where are you guys ??? Bryan, Larry,
Tyson or any one ???? no buddy knows the answer ??? please if any one can
explain this to me .....
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
