Inbound rate limiting on Cisco 3750 not working

Dear Cisco Guru,

I am trying to do rate limiting on our cisco 3750 but it does not seems to work. No packets are catched when using: show policy-map interface Gi 1/0/5.

Please find my configuration bellow:



Current configuration : 5289 bytes

mls qos

!
class-map match-any VOIP
  match ip dscp ef
class-map match-any VMWARE
  match access-group 101
class-map match-any AS400
  match access-group 100

policy-map QoS_FO
  class VOIP
   set dscp ef
    police 1000000 12500 exceed-action drop
  class AS400
   set dscp af41
    police 6000000 75000 exceed-action drop
  class VMWARE
   set dscp af31
    police 38000000 475000 exceed-action drop
  class class-default
   set dscp default

There is not even traffic catch by the class-default, what the hell is going on ?
Thanks a lot for any help you could give me.

Looks right to me, Is the truck going to Router or Switch ? This is a core switch right? any distribution layer or access switch after it?

Dear Kavlins,

Thanks for your anwser, this port (gigabitEthernet 1/0/5) is connected to the telco switch providing us a optical fiber between 2 remote sites. To be more precise, I would like to do QoS on this optical link between our 2 remotes site but I don't have any administrative access to the telco switches.

LOL I was banging my head for the same issue 2 months ago. Now go to this link and read the fine print
http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.1_11_ax/command/reference/cli2.html#wp2784632
show policy-map
Note Though visible in the command-line help string, the interface keyword is not supported, and the statistics shown in the display should be ignored.
