This is what the Cisco 3560 Qos Reference Guide has to say on the matter:<http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/12.2_20_se/configuration/guide/swqos.html>
"Note Do not use the show policy-map interfaceprivileged EXEC command to display classification information for incoming traffic. The interface keyword is not supported, and the statistics shown in the display should be ignored." As has been said, the inbound Qos based service-policy limitation and the failure of the "*show policy-map interface*" command to reflect stats on the Cat 3560 are normal behaviour. I have also observed this on the Cat 3550. I use the *sh mls qos interface xx statistics* command instead I also use the *mls qos monitor dscp *xx xx xx xx xx xx interface command to spice up the output.
