    Example: Percentage-Based Hierarchical Rate-Limit Profile for External Parent Group

    The following example creates rate-limit profiles with rate based on percentage and burst in milliseconds. You can create a policy using these rate-limit profiles and attach them to different interfaces using different parameter values.

    1. Create a policy parameter refRlpRate.
      host1(config)#policy-parameter refRlpRate reference-rate host1(config-policy-parameter)#reference-rate 100000host1(config-policy-parameter)#exit
    2. Create a hierarchical rate-limit profile rlpData.
      host1(config)#rate-limit-profile rlpData hierarchical host1(config-rate-limit-profile)#committed-rate refRlpRate percentage 10 host1(config-rate-limit-profile)#peak-rate refRlpRate percentage 100 host1(config-rate-limit-profile)#exit
    3. Associate this hierarchical rate-limit profile with the external parent group.
      host1(config)#parent-group epg1 host1(config-parent-group)#rate-limit-profile rlpDatahost1(config-parent-group)#exit
    4. Create a hierarchical policy parameter.
      host1(config)#policy-parameter A hierarchical host1(config-policy-parameter)#aggregation-node forwarding host1(config-policy-parameter)#exit
    5. Create a policy that references the external parent group.
      host1(config)#ip policy-list P host1(config-policy)#classifier-group data external parent-group epg1 parameter A host1(config-policy-classifier-group)#forwardhost1(config-policy-classifier-group)#exit host1(config-policy)#exit
    6. Attach an IP policy P at interface atm5/0.1 by specifying a different reference-rate value.
      host1(config)#interface atm 5/0.1 host1(config-if)#ip policy-parameter reference-rate refRlpRate 5000000 host1(config-if)#ip policy input P stats enabled
    7. Attach an IP policy P at interface atm5/0.2 to use the default value.
      host1(config)#interface atm 5/0.2 host1(config-if)#ip policy input P stats enabled
    8. Display the policy list.
      host1#show policy-list
      
      Policy Table
      ------ -----
      IP Policy P
         Administrative state: enable
         Reference count:      2
         Classifier control list: cl1, precedence 100, external parent-group epg1 parameter A
            forward
      
         Referenced by interface(s): 
            ATM5/0.1 input policy, statistics disabled, virtual-router default
            ATM5/0.2 input policy, statistics enabled, virtual-router default
      
         Referenced by profile(s): 
            None
      
         Referenced by merge policies:
            None
      
      
    9. Display the interface configuration to verify the reference rate (committed rate and peak rate) being different for both interface attachments (only the policy-related section of the output is shown).
      host1#show ip interface atm 5/0.1
