QoS Problems

Unanswered Question
Mar 3rd, 2009

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

service-policy output policymap1

and does not work either, the result is the same with or without QoS

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

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
