Rate limiting not working on 6504E

I limit my customers on 6504E using rate-limiting but the customers shoot beyond the rate-limit.I configure rate-limiting on Cisco 6504E with the following cards:

IOS:

s72033-advipservicesk9_wan mz.122-18.SXF8.bin

Cards

Supervisor Engine 720 (Active) WS-SUP720-3B

SFM-capable 16 port 10/100/1000mb RJ45 WS-X6516-GE-TX

interface GigabitEthernet4/3

ip address X.X.X.X

ip nat outside

NO rate-limit input 45000000 5625000 11250000 conform-action transmit exceed-action drop

no rate-limit output 45000000 5625000 11250000 conform-action transmit exceed-action drop

no cdp enable

Re: Rate limiting not working on 6504E

use policing with policy map better

for example

acceess-lis 100 permit ip [source] [distnation]

class-map map1

match access-group 100

policy-map policy1

class map1

police 450000 conform-action transmit exceed-action drop

then apply it to the interface

like

interface [port number]

service-policy input policy1

good luck

if helpful Rate

Re: Rate limiting not working on 6504E

What might be happening, your policier is allowing bursts. If your reduce your burst size (or interval), the policier will behave more like a physical interface for that data rate, although also acting like an interface with a small queue. If supported, you might consider using a shaper to regulate speed. As you reduce the burst size, it too behaves more like a physical interface for that data rate but it queues the excess instead of dropping it.
