James it is because the max reserve by default is only 75%. You would
need to change this value if you wanted to use more then 75% of the
interface bandwidth in your policy. See link below for command
reference.

Subject: QoS question
When I build a CBWFQ policy....such as this:
class-map match-all qos1
match access-group name qos1
class-map match-all qos2
match access-group name qos2
!
!
policy-map qos
class qos1
bandwidth percent 15
class qos2
bandwidth percent 30
class class-default
bandwidth percent 45
!
Why do I get the following after applying it to a serial interface:
Router(config-if)#service-policy out qos
I/f Serial0/0 class class-default requested bandwidth 45%, available
only 30%
Tought that it allotted for the over head....how much do I have to take
off the top, and to get those percentages, do I use a bandwidth (no
percentage) statement and what is the base line of bandwidth I start
subtracting from?
Router#sh int s0/0
Serial0/0 is up, line protocol is up
Hardware is PowerQUICC Serial
Internet address is 1.1.1.1/24
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
Look forward to any responses, thanks!
