Both bandwidth and bandwidth percent are affected by the limit. Since your
policy is asking for 85%, the max reserved bandwidth needs to be set to 85
or higher for the router to accept the policy being applied to the
interface.

Subject: CBWFQ bandwidth percent command
Hi All,
I have the following policy-map:
!
policy-map MYPOL
class Web
bandwidth percent 40
class Email
bandwidth percent 30
class Management
bandwidth percent 15
!
I received the following error message when applying it on interface s0/0:
R8(config-if)#service-policy output MYPOL
I/f Serial0/0 class Management requested bandwidth 15%, available only 5%
I think it has something to do with the "max-reserved-bandwidth" which is by
default 75% of interface bandwidth. I was under the impression that only
"bandwidth <kbps>" commands in the policy-map are subjected to this 75%. And
"bandwidth percent" commands are assessed against the total interface
bandwidth, which in my case is 1544 Kbit.
Solution:
R8(config)#int s 0/0
R8(config-if)#max-reserved-bandwidth 100
R8(config-if)#service-policy output MYPOL
R8(config-if)#do sh run int s 0/0
Building configuration...
Current configuration : 182 bytes
!
interface Serial0/0
ip address 172.30.78.1 255.255.255.254
max-reserved-bandwidth 100
service-policy output MYPOL
end
I guess I'm probably wrong about my understanding. Can I hear any opinions?
Thank you.
B.Rgds,
Lim TS
