I am having some issues using CAR. When I apply the rate-limit command to all outbound traffic, CAR works fine.
However, when I apply an access-list to the rate-limit command, my comformed and exceeded packets both show zero. Here is my config.
interface Serial0/0
ip address 201.150.30.2 255.255.255.252
ip access-group 101 in
rate-limit output access-group 102 512000 512000 512000 conform-action transmit exceed-action drop
no ip mroute-cache
access-list 102 permit ip host 201.150.30.240 any
access-list 102 permit ip host 201.150.30.241 any
access-list 102 permit ip host 209.150.30.242 any
Thanks
Again, when I remove the access-list CAR works fine. So it seems there is something wrong with the access-list, but it looks fine to me

In the above command the 512kb which you had for Normal burst size and Excess burst size seems to be high, configure a less value abd see whetehr it is working

If you check the whitepaper http://www.cisco.com/warp/customer/cc/pd/iosw/tech/carat_wp.htm
Cisco recommended formula for calculating normal and extended burst values are:
norm.burst=(rate /8) *1.5
ext.burst= norm.burst * 2
For a bit rate of 512000 bps norm.burst= 96000, ext.burst=192000 should work.
