Police percent not supported - no bandwidth for percent calculation

Hello,

I want to perform QoS on specific (or all the) L2TP sessions that establish on ASR1006 router (LNS).

What I have managed already is to set a police at a specific rate for a class that matches access-list 100 with the following code and it is working ok (tried one user and it limits bandwidth to 800 kbps):

class-map match-all class1
 match access-group 100
!
policy-map child
 class class1
  police 800000 100000 100000 conform-action transmit exceed-action set-qos-transmit 1 violate-action drop
policy-map parent
 class class-default
  service-policy child

Now what I want is to set the police cir as a percentage because I want to apply the policy-map on various pppoe sessions with different speed. But when for example I change the police with "police cir percent 50 pir percent 60" I get the following error:
police percent not supported - no bandwidth for percent calculation

Please your help.

QoS needs a percentage of a specific bandwidth value.  Add config "bandwidth qos-reference <value>" to the interface.

If it was only one interface I could do that. But I speak about L2TP sessions on a LNS. Every session is a Virtual Access interface with different bandwidth...

I apply the policy-map either on the Virtual Template or at specific user(s) through Radius. I can't execute your solution.

I use RADIUS to apply the config to the virtual access interface when it gets spawned when a user connects.  The bw percent in the policy remains the same (50%) and the qos-reference <value> is set accordingly per user.   The service policy is also applied to the virtual-access interface via RADIUS attributes.

                                Cisco-AVPair += "ipsec:route-set=interface"

Thank you very much but it is not what I need. I want the interface bandwidth to be discovered automatically.
