PIR (EIR) in Ethernet Carrier environment

Hi all,

i have a question regarding bursting in ethernet networks.

Is there a way to configure policing on an ISR (28xx) router, that i  get some kind of PIR (EIR) behaviour for an Ethernet WAN connection?

My consideration is, that i get a scenario where i can have e.g. 4  MBit/s of CIR traffic and if i do not use the full 4 MBit/s for some  time i can burst to eg. 8 MBit/s (because i have saved some "tokens" for  instance).

I have tried a configuration (but with an error):

policy-map egress_queue_test
class voice
    priority percent 24
class gold
    bandwidth percent 40
class silber
    bandwidth percent 16
class system_intern
    bandwidth percent 5
class class-default
    bandwidth percent 10

policy-map pm_test
class class-default
   police cir 4000000 bc 400000
  service-policy egress_queue_test

r-test(config)#interface GigabitEthernet0/0.2702
r-test(config-subif)#service-policy output pm_test
Cannot attach queuing-based child policy to a non-queuing based class

Many thanks for your input,

N.
