[c-nsp] ATM Subinterface QoS

[cisconsp at SecureObscure.com]

You might want to add the atm over-subscription config under the main
interface:

interface ATM0/1/2
 no ip address
 atm over-subscription-factor 10
 no atm ilmi-keepalive
!
interface ATM0/1/2.31701 point-to-point
 ip vrf forwarding V10001:ABC
 ip address W.X.Y.Z 255.255.255.252
 pvc 100/701 
  vbr-nrt 49760 49760 500
  oam-pvc manage 0
  encapsulation aal5snap
  service-policy output POLICY_PECE_10M_TO_100M_6Q
 !
 interface ATM0/1/2.31702 point-to-point
 ip vrf forwarding V10002:XYZ
 ip address W.X.Y.Z 255.255.255.252
 pvc 100/701 
  vbr-nrt 49760 49760 500
  oam-pvc manage 0
  encapsulation aal5snap
  service-policy output POLICY_PECE_10M_TO_100M_6Q
 !
And so on and so forth.

OK, it worked well for one customer circuit but after adding the same
vbr-nrt and service-policy to more subinterfaces on the same OC3, all of the
interfaces that I made the change to began having problems, almost like a
limit was being shared between all of the subinterfaces on the main
interface. 

I didn't see anything on the referenced URL that mentioned a similar side
effect. Any ideas?

Thanks
Dave
