Nesting QoS Policies

Hi All,

I'm having a bit of a mental blank here.

Scenario:

We provide a 2Gig symmetrical link to a customer. To ensure that the customer does not exceed this, we police them to 2G using a policer like so (see current config below).

My predicament is that I also want to reserve 20M of the bandwidth (outbound) for the customer's video conferencing applications.

Current Config:

policy-map CUSTOMER-LIMIT
class class-default
    police 2000000000 375000000 512000000 conform-action transmit exceed-action transmit violate-action drop
!
interface TenGigabitEthernet0/0/0.500
encapsulation dot1Q 500
service-policy input CUSTOMER-LIMIT
service-policy output CUSTOMER-LIMIT

Proposed Config:

ip access-list extended ACL-CUSTOMER-VIDEO-APP
permit ip any A.A.A.A X.X.X.X
!
class-map match-all CLASS-CUSTOMER-VIDEO-APP
  match access-group name ACL-CUSTOMER-VIDEO-APP
!
policy-map POLICY-CUSTOMER-VIDEO-APP
  class CLASS-CUSTOMER-VIDEO-APP
    bandwidth 20000
  class class-default
    fair-queue
    random-detect

Question:

I'm not sure how to nest the two policy-maps together so that the link remains being policed at 2G while under that the customer's video app is reserved 20M out of the 2G bandwidth based on the ACL.

Any help would be greatly appreciated.

Thanks.

Andy

ok I think it can be accomplished like this...

policy-map CUSTOMER-LIMIT
class class-default
  police 2000000000 375000000 512000000 conform-action transmit exceed-action transmit violate-action drop
  service-policy POLICY-CUSTOMER-VIDEO-APP
