I have a problem with using shape average percent command and applying policy to physical interface after upgrading the 3800 router from 12.4(15)T12 to 15.1(4)M7.
QoS configuration:
class-map match-any INTERACTIVE-VIDEO
match dscp cs5
match dscp cs4
class-map match-any CRITICAL-DATA
match dscp af41 af42 af43

match dscp af11 af12 af13
class-map match-any CONTROL
match dscp cs6

match dscp cs2
class-map match-all VOICE
match dscp ef

Problem 1.
The shape average percent 80 is not correctly intrepreted. As shown from "show policy-map" the shaper shape traffic to 80 mbps.

Problem 2.
I can not apply policy to physical intaface.
3825-region_1(config)#interface gigabitEthernet 0/0
3825-region_1(config-if)#service-policy output WAN-EDGE-SHAPER
Service_policy with queueing features on this interface is not allowed
if tunnel based queuing policy is already installed Remove tunnel policy first and then install policy on this interface and later on tunnel
3825-region_1(config-if)#
