Bandwidth policing by VLAN

I have a number of customers sharing an internet connection and I want to rate limit them all so they don't use up all of the pipe at once.
Each customer is assigned a VLAN.

Need some help with the Cisco Syntax;
How can I create a QoS policing policy to rate limit them?
Whenever I try to apply a police it doesn't stick in the configuration.

class-map match any RATELIMIT

policy-map RATELIMIT
    police cir 25600000 bc 312500 be 312500 conform-action transmit exceed-action drop violate-action drop

int vlan 20
  service-policy input RATELIMIT
  service-policy output RATELIMIT

*That last bit doesn't stick in the config, it takes the command but then doesn't apply to the running config?

Try removing the input policy and just apply the output policy, and see if that makes a difference.

Try using two different policy names for the input and output policy.

nope same thing, I enter the policy command and it accepts it but it doesn't list the command in the running config.

Turns out this switch doesn't support applying the policy to VLANs, have to apply it to a physical interface
