We have some LNSs running 12.4 SP Services, running with the following config (qos specific lines and currently not working):
!
class-map match-all voice-signaling
match access-group 101
class-map match-all voice-traffic
match access-group 102
!
!
policy-map sub-policy
class voice-traffic
priority 240
class voice-signaling
bandwidth 16
policy-map XXX_qos-voice
class class-default
shape average 256000
fair-queue
service-policy sub-policy
!
interface Virtual-Template1
ip unnumbered Loopback0
ip mroute-cache
no peer default ip address
ppp authentication chap
no clns route-cache
!

in the feature set for the IOS currently running it suggests this configuration should work, however it will not apply the policy via the Cisco-AVPair command (the command is visible via the debug AAA per user so radius is working, even when we test it by applying the service-policy to the actual virtual-template it errors saying it will only work on an MPL bundle. From what I have read it is suggested that even though this feature is supposed to work, it does not in practice and an upgrade to a feature set which includes QoS:per session shaping and queueing on LNS is needed.
If anyone has any experience of the or has any suggestion of if we can achieve our QoS for voice per session with the current IOS that would be great.

Hi Per session shaping on LNS is only supported in 12.2SB train starting with 12.2(28)SB

Thanks for that, am I correct in thinking I have to upgrade our NPE-400's to NPE-1G minimum for 12.2SB? or do they need to be NPE-2G?
Thanks

This feature is not related to the NPE type. This feature is performance impacting so you should do some tests to see if your NPE-400 can support the number of L2TP tunnels you want with this feature enabled. If it's not the case, you will have to upgrade your NPE.
