Policy Map on Subinterface

I have several locations in my network.  Some have Cisco 2800's with 2 physical ethernet interfaces - these are ok.  The issue is with a 2600 at one site that has only one physical enet interface.  I am trying to put a policy map using the following commands to force traffic from a specific IP to the video plane on my ISP's mpls network:

ip cef

!

!

ip access-list extended video

  permit ip host 172.16.102.11 any

!

!

class-map match-all video

  match access-group name video

!

!

policy-map outbound

   class video

   set ip precedence 4

   bandwidth 845

   class class-default

   set ip precedence 0

!

!

!

interface fa0/1.76

 service-policy output outbound

The issue appears to be that policy maps are not supported on subinterfaces - is there any way I can still accomplish this goal with the existing hardware?  Would it work to put the map on the main interface?

you could put this in the main interface it would apply to all traffic that was defined in the ACL one problem I do see is that you are trying to apply this outbound and you can not do that inbound is the only way a route map works you could put it in your serial or outside facing interface.

actually, this ethernet sub interface is the outbound interface facing the ISP's bridge - there is no serial connection to the ISP

then just turn the map around and put it on the subinterface facing your lan.

interface 0/1.76 points to the ISP''s private MPLS network, and interface 0/1 points to the LAN

then you would want to put it in the fa 0/1 interface not the subinterface and then you may want to expand your ACL so it only tags Video traffic rather than everything from that host.
