Managing bandwidth on WAN through microflow output policer

Hi,


I have a central site with a 6k5/Sup720 connecting many remote sites through leased lines (mostly 6k5/Sup720).


I would like to protect my WAN in configuring an output policer on both HQ router and remote site router.


For example, imagine on my central site connecting a 2 Mbits/s remote site with a 512 kbits/s visioconf endpoint :


Extended IP access list myVISIO

    10 permit ip any host 10.10.10.1


class-map match-all myVISIO

  match access-group name myVISIO


policy-map myTEST

  class myVISIO

   police cir 512000 bc 16000 be 16000    conform-action transmit     exceed-action transmit     violate-action transmit

  class class-default

   police cir 2048000 bc 16000 be 16000    conform-action transmit     exceed-action drop     violate-action drop


And on my remote site :


Extended IP access list myVISIO

    10 permit ip host 10.10.10.1 any


class-map match-all myVISIO

  match access-group name myVISIO


policy-map myTEST

  class myVISIO

   police cir 512000 bc 16000 be 16000    conform-action transmit     exceed-action transmit     violate-action transmit

  class class-default

   police cir 2048000 bc 16000 be 16000    conform-action transmit     exceed-action drop     violate-action drop


This should in theory do the work.


Starting with 15.1(2)SY I should be able to microflow policing in output (

)


But I am not able to understand the example.


Anybody could post a working example ?


Thanks,


Fred
