I see you have your PVC as vbr-nrt.
Orig poster has UBR
When we've tested QoS on ADSL we found the PVC had to be configured as
VBR-NRT to make QOS work. this may be the issue here.
I'm sure I found a reference on CCO to this behaviour but cant find it again
quickly.

Dean

Hi,
Subinterfaces and software interfaces do not have their own separate
transmit (Tx) ring; therefore, no congestion can occur. These interface
types include dialers, tunnels, and Frame Relay subinterfaces, and will only
congest when their main hardware interface Tx ring congests. The Tx ring
state is an indication of congestion for software interfaces.
router(config)# interface Serial0/0.1
router(config-subif)# service-policy output test
CBWFQ : Not supported on subinterfaces
1.- Create a child or lower-level policy that configures a queueing
mechanism. In the example below, we configure LLQ using the priority command
and CBWFQ using the bandwidth command. Refer to Congestion Management
Overview for more information.
policy-map child
class voice
priority 512
2. Create a parent or top-level policy that applies class-based shaping.
Apply the child policy as a command under the parent policy since the
admission control for the child class is done based on the shaping rate for
the parent class.
policy-map parent
class class-default
shape average 2000000
service-policy child
3. Apply the parent policy to the subinterface.
interface Serial0/0.1
service-policy parent
Cisco Page: http://tinyurl.com/ytt8ge
Note: Class-based shaping works at the interface and subinterface level.
Cisco IOS 12.2(2.5) introduces the ability to configure shaping on the main
interface and IP addresses on the subinterfaces.

Whenever I try to apply the following I get an error message about how
CBWFQ can't be applied to subinterfaces. What is the correct way to do
this?
Thanks,
