We have a site with a 10mb mpls link and the bandwidth is being maxed out with uploads and downloads to a specific IP website.
What is the best way of policing this so that only 40% of the bandwidth can be allocated to this site.
Am i on the right track with this
interface GigabitEthernet0/1
description MPLS
ip address 172.**.**.** 255.255.255.252
ip flow ingress
rate-limit output access-group 60 4000000 4000000 4000000 conform-action transmit exceed-action drop
Standard IP access list 60
10 permit 10.**.**.**

Hi
40% of the download bandwidth
Standard IP access list 60
10 permit 10.**.**.**
class-map match-any websp
match access-group 60
policy-map Shapesp
class-map websp
shape average 4000000
class class-default
interface GigabitEthernet0/1
service-policy input Shapesp
this will limit traffic from 10.**.**.** to 4mbps
dont forget to rate post if it helps

Andrew,
You're on the right track, but this particular setup would limit the 10.x.x.x subnet to 40% of the total link all the time regardless of destination. Do you have MQC on this router? I would strongly recommend using that as compared to this because you can match on source/destination addresses, source/destination port, etc. If you don't have it because of IOS version, then you may be able to make the above better by doing an extended acl and specifying the 10.x.x.x subnet going to the 1 site that you want to control. You also would want to limit the inbound coming from that site to the 10.x.x.x subnet as well. You may also need to change your normal and max burst bytes to the lowest value instead of equal to the cir.
HTH,
John

I wasn't talking about the whole subnet, it is a specific address. 10.1.25.76. We do have MQC on the router so i will look into that
