I try using MQC and CAR into cisco 3725 following
rate-limit output access-group 100 160000 1500 2000 conform-action continue exceed-action drop
but this rule does not work, and i try the follow rule
access-list 100 permit ip any any
class-map match-all classmap1
match access-group 100
policy-map policymap1
class classmap1
shape average 8000
interface FastEthernet0/0
ip address 10.0.0.121 255.255.255.0
service-policy output policymap1
and does not work either, the result is the same with or without QoS

Try instead:-
policy-map policymap1
class class-default
shape average 2048000
service-policy shape
policy-map shape
match access-group 100

Your configs look correct. How are you basing that this isnt working? Are your show commands (show policy-map int fa0/0) not showing matched data? What are you trying to accomplish. Shaping and police will do to differnt things. Shaping has buffers policing (rate-limit command) does not.
Also in your rate limit command your burst values are quite low. I think they should be 30000 and 60000
(160000/8)*1.5= 30000
30000x2= 60000

hi Ricardo,
As Michael pointed out, your burst size in CAR (rate-limit) is very low. If the burst size is too low, the achieved rate will be smaller than the configured rate.
Another point is, the equivalent of CAR is MQC police and not shape.

hi
yes its showing matched data, I using the dynamips emulator, tested with an Cisco ASA rule MQC and i have worked, then i think the problem is the dynamips. thanks
