hi
We normally use rate-limit(CAR) to restrict the bandwidth on an interface.But you can achieve your requirement using access-list binded to the rate-limit(CAR) command restricting the bandwidth to 64K.
Create an Access-list permitting the required from the source address and bind it with the rate-limit command , for more info on cli do refer the below link.

Hello,
Thanks for your response,
I have tested the CAR method, but I don?t understand a lot the different parameters of the command, especially what is the utility and the difference between burst-normal and burst-max, and how to choose these values.
thanks a lot

Hi
Additionally u can also rate-limit the traffic using a policy-map and policing the respective class-map to 64 k where the access-list having the source ip is called in the class-map.

Hi,
the config achieving this would be:
ip cef
class-map match-all IP2limit
match ip address 10
policy-map limit64k
class IP2limit
shape average 64000
interface Serial0
service-policy output limit64k
access-list 10 permit host 172.20.20.1
You need to adjust interface naming. The policy would limit the host 172.20.20.1 to an average of 64000 bps through shaping.
Hope this helps! Please rate all posts.
