	There's only one case when you can *DO* egress policing on
cat3550 platform but you're restricted to use *ONLY*:

 --  class-map w/ "match ip dscp"
 --  action = "police"
  
  http://tinyurl.com/2a94rx4  --> Step #14

!
!
mls qos
!
class-map match-all SCAVENGER
  match ip dscp cs1 
!
policy-map EGRESS
  class SCAVENGER
    police 8000 8000 exceed-action drop
!
interface FastEthernet0/1
 service-policy output EGRESS
 mls qos trust dscp
 mls qos monitor dscp 8
 mls qos monitor packets
