[c-nsp] 837 LLQ Policy-Map problem

[Eric Helm]

I have an 837 router with 12.3(14)T IOS running.
I have a couple of problems.
First, when making policy-maps, the shape average command does not 
appear in the running config.
Example commands input:
policy-map INGRESS-VOIP-POLICY
  class class-default
   shape average 256000
   service-policy VOIP-LLQ-CHILD

A show run reveals that the 'shape average 256000' is not there.

Furthermore, when I try to apply the service-policy to any interface, or 
an ATM pvc, IOS accepts the command 'service-policy output VOIP-POLICY, 
however a show run reveals that the command is not present. Also a show 
policy-map interface output confirms that there is no service policies 
applied to any interface.
I do have an input service-policy that works as expected.

Does the 837 not support LLQ?
I have several 831 routers with similar IOS that work just fine with 
these commands.

Other potentially relevant config:

class-map match-all VOIP-CONTROL-BANDWIDTH
  match ip dscp cs5
class-map match-all MARK-VOIP-RTP
  match access-group name VOCALDATA-RTP
  match protocol rtp audio

  match access-group name VOCALDATA-VOIP-CONTROL
class-map match-all VOIP-LLQ
  match ip dscp ef
