Example: Service and User Rate-Limit Hierarchy Overlap Hierarchical Policy Configuration

In the service and user rate-limit hierarchy overlap configuration example:

This example uses the following:

  1. Create an aggregate rate limit that can be applied to each IP session. Create an external parent group to hold this rate limit.
    host1(config)#rate-limit-profile USER_RATE two-rate hierarchicalhost1(config-rate-limit-profile)#committed-rate 2000000 host1(config-rate-limit-profile)#committed-action transmit final host1(config-rate-limit-profile)#exit
    host1(config)#parent-group EPG2 host1(config-parent-group)#rate-limit-profile USER_RATE host1(config-parent-group)#exit
  2. Create an aggregate rate limit that can be shared across multiple video streams. Create an external parent group to hold this rate limit.
    host1(config)#rate-limit-profile AGG_VIDEO two-rate hierarchical host1(config-rate-limit-profile)#committed-rate 1000000 host1(config-rate-limit-profile)#committed-action transmit conditional host1(config-rate-limit-profile)#exit
    host1(config)#policy-parameter B hierarchical host1(config-policy-parameter)#exit
    host1(config)#parent-group EPG1 host1(config-parent-group)#next-parent EPG2 parameter B host1(config-parent-group)#rate-limit-profile AGG_VIDEO host1(config-parent-group)#exit
  3. Create a policy list to be attached to each IP session.
    host1(config)#ip classifier-list VIDEO_CLACL udp any any eq 4000
    host1(config)#policy-parameter A hierarchical host1(config-policy-parameter)#exit
    host1(config)#ip policy-list IP_POL host1(config-policy-list)#classifier-group VIDEO_CLACL external parent-group EPG1 parameter A host1(config-policy-list-classifier-group)#forward host1(config-policy-list-classifier-group)#exit host1(config-policy-list)#classifier-group * external parent-group EPG2
    parameter B
    host1(config-policy-list-classifier-group)#forward host1(config-policy-list-classifier-group)#exit host1(config-policy-list)#exit
  4. Attach IP_POL to each IP session. Specify the same ID for parameter A, but a different ID for parameter B.
    host1(config)#interface fastEthernet 3/0.1 host1(config-interface)#vlan id 1 host1(config-interface)#exit
    host1(config)#interface ip 3/0.1.1 host1(config-interface)#ip policy-parameter hierarchical A vlan host1(config-interface)#ip policy-parameter hierarchical B forwarding host1(config-interface)#ip policy input IP_POL statistics enable host1(config-interface)#exit
    host1(config)#interface ip 3/0.1.2 host1(config-interface)#ip policy-parameter hierarchical A vlan host1(config-interface)#ip policy-parameter hierarchical B forwarding host1(config-interface)#ip policy input IP_POL statistics enable host1(config-interface)#exit
