[cisco-nas] VPDN QoS

The documentation on this is rather sketchy,
I'd like to be able to terminate a PPP user via L2TP and apply a Quality
~ of Service (service-policy) to the vaccess interface, downstream to the
user, just can't seem to make this happen.

Tried initially with this configuration:


!
class foo
~ match ip dscp ef
policy bar
~ class foo
~ priority 210
!

and in RADIUS:

a. lcp:interface-config=service-policy output foo

No joy, user fails to complete vtemplate cloning.

b. ip:sub-policy-Out=foo

User connects, debug aaa per-user displays:

~ AAA/PER-USER: Could not set output QoS policy to foo

Not exactly helpful, debug vtemplate cloning and debug vtemplate error
do not yield any more information.


I came across this earlier post :

http://puck.nether.net/pipermail/cisco-nas/2005-May/001088.html

Which states that queuing is not supported on l2tp vaccess,
fine, if this is the case I would expect to be able to
at least police the class-default traffic away from the
traffic I care about, so I try this approach:

!
class foo
~ match ip dscp ef
policy bar
~ class foo
~ class default
~  police 1536000
!

Nada , exactly same result with both above approaches.

Target platform is C7200 running 12.3 mainline.


I have done some scouring and can't seem to find any decent
documentation, working examples or debugs to assist me further,
can anybody provide me with some pointers?

Many thanks,
