[c-nsp] Basic QoS on ATM subinterfaces

[Dave Weis]

Hello All

I've got a PA-A3-OC3 that is terminating a large number of PPPoA 
connections. I need to do basic QoS/prioritization for voice traffic. 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

Most of the examples I saw that did work involved one or two interfaces 
of a known speed. The customers that are connecting to this vary from 
256k to 30 megabits. I don't want to individually configure any portion 
of the solution per customer.

I do have control of the radius configuration and can insert attributes 
that contain the speed that each customer is provisioned for if that 
would help.

Any ideas? Below is what I ended up with.

class-map match-all EVERYTHING
  match access-group name EVERYTHING
class-map match-all IS-VOICE
  match access-group name IS-VOICE
!
policy-map IS-VOICE
  class IS-VOICE
   priority percent 75
   set dscp ef
  class EVERYTHING
   set dscp default
policy-map VOICE-PARENT
  class class-default
   shape average percent 100
   service-policy IS-VOICE
!
ip access-list standard EVERYTHING
  permit any
!
ip access-list extended IS-VOICE
  permit ip 192.168.221.0 0.0.0.63 any

Thanks!
dave
