Configuring Bandwidth Control on CAT 3550

[crisisman]

Hi,
I am trying to configure my Cisco Catalyst 3550 switch with bandwidth control function it is running 12.1(11)EA1 IOS.
What I did is to follow the examples provided in the cisco website:

http://www.cisco.com/en/US/products...figuration_guide_chapter09186a00800c6ed7.html

But I am trying to limit the outgoing bandwidth and not incoming and it is stated in the cisco site that only match ip dscp is support for that purposes. However, I have tried on the dscp number and none seems to work.
Below is my class-map:
class-map match-all BWC
match ip dscp 2

Below is my policy map:
policy-map EMb
class BWC
police 64000 8000 exceed-action drop

And this is the interface that I am working on:
interface FastEthernet0/2
no switchport
bandwidth 512
ip address x.x.x.x 255.255.255.240
duplex full
speed 100
service-policy output EMb
storm-control broadcast level 50.00

My aim is to limit the amount of outgoing bandwidth on my interface to 128kbps.
Any assistance would be greatly appreicated.

Regards,
Vincent
