yes

>If it is possible then how is it done as I assume queuing happens after
L2TP encapsulation.


Just apply pwfq policy to the subscriber if you want per-subscriber queuing.
Be careful that the line card / EPPA that has the circuit for the subscriber
and that which has the circuit for the l2tp tunnel are the same otherwise
PWFQ won't work . I see you are discussing this with david already.

If you want to apply qos to the aggregate traffic as well / instead, you can
also apply pwfq to the egress circuit to the lac. If you try to do _both_
(subscriber and aggregate), be careful. There's no H-Qos for l2tp lns.
