Hi Mike,

You can apply the QOS_POLICY directly to the main interface. But if you
would like to apply it to a sub-interface, you cannot. The router will tell
you that. This is because the sub-interface by default does not have a queue
associated with it. The work-around is to create a parent shaping policy
which initiates a queue.

policy-map SHAPE
 class class-default
 shape average 1000000 !*** THIS IS MISSING IN YOUR EXAMPLE ****
 service-policy QOS_POLICY

The following post is relevant to your question. Cisco DOC has an example
explaining this, but I cannot find the link.

Hello,

   If you look at the below answer he used nested QOS. Couldn't we just
apply
the inner policy (QoS_POlicy) directly to the interface since it is going to
affect all traffic?

class-map match-all HTTP
match protocol http
class-map match-all SMTP
match protocol smtp
!
class-map match-any PEER-TO-PEER
match protocol fasttrack
match protocol gnutella
match protocol kazaa2
!
policy-map QOS_POLICY
class HTTP
bandwidth 2000
class SMTP
bandwidth 1000
class PEER-TO-PEER
police cir 8000
!
policy-map SHAPE
class class-default
service-policy QOS_POLICY

Thanks,
