We recently moved from a Serial to an Ethernet link for one of our WAN links.
We created a parent service-policy, included the shape average command and the old service policy as a child. Then we applied the new parent service-policy on the subinterface.
It seems that after applying the QoS service-policy to the subinterface on the router it is not applying the policy since the show policy-map interface output counters remain at zero.
Below is the relevant configuration, any ideas?
class-map match-any Priority
match ip precedence 1
class-map match-any Normal
match ip precedence 0
class-map match-any Voice
match ip precedence 5
policy-map QoS
class Priority
priority 256
class Voice
priority 576
policy-map QoS-Parent
class class-default
shape average 2097152
service-policy QoS
int fa0/1.667
service-policy output QoS-Parent
Thanks!

Hello Joe,
support of modular QoS on subif is platform dependent and in some cases IOS vers. dependent.
What router are you using ?
Try to think of a different configuration using extended ACLs to define classes to use a policy-map applied at the physical interface.
Otherwise you will need a dedicated interface.
Hope to help

It's a 2811 running 12.4 Advanced Enterprise (c2800nm-adventerprisek9-mz.124-15.T3.bin)
Do you know where I can find out if this router supports module QoS on subinf or where I can find a list of routers that can support it?
Thanks!

Don't know if this is the cause of your problem, but I have documented with Cisco that certain configurations of QoS within the 12.4(15)T train don't properly update counters. (The QoS, though, did seem to function correctly.) You might try upgrading to 12.4(15)T7 or 12.4(20)T. (Also don't know if problem fixed in either.)

Open a case with TAC 1800-553-2447. TAC will be able to provide you configuration assistance and feature support.
