I've got a PA-A3-OC3 that is terminating a large number of PPPoA

I
am using a subinterface per VPI with a vc-class to reference the
virtual-template.
I have set up a parent/child policy-map as the documentation suggested
but trying to apply it doesn't work:
router(config)#int atm4/0
router(config-if)#service-policy output VOICE-PARENT
GTS : Not supported on this interface
No, this won't work. You've got several places you can apply the template:
-On the sub-interface
-On the PVC, with the outer shaper removed
-On the virtual-access (via the virtual-template)
If you're bulk-terminating a bunch of PPPoA sessions, I'd suggest that you want
it applied to the virtual-access interface. You can do this by either applying
it to the virtual-template (if you're sure you always want the same policy for
all the users), or push it back from RADIUS as a Cisco-avpair as each
virtual-access interface is cloned.
OK, something like this:
class-map match-all EVERYTHING
match access-group name EVERYTHING
class-map match-all IS-VOICE
match access-group name IS-VOICE

I have applied this configuration but the only interfaces that show up
in show queueing are MLP bundles. The PVC's that show up after that
section all list the queueing as FIFO still:
router#show queueing

Have I missed something else?
