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).
