The winner is Chris Parker who gave me the clarification: The policed-dscp wil only remark packets that already had dscp 24 to dscp 8. The second one will remark all traffic to 8 if it exceeds the policed rate. Thanks, Kevin

And I'm not positive, but I don't believe you'll see the set-dscp-transmit option on a 3750 unless it is a Metro E class switch.

Why the burst size is 8000, is this a default value?? Also in SNRD, police in auto qos for switching use the same value.
