# Creating Rate-Limit Profiles

Create rate-limit profiles with a rate based on percentage and a burst in milliseconds. The system creates a policy using these rate-limit profiles and then attaches them to different interfaces using different parameter values.

1. Create policy parameter refRlpRate.
   host1(config)#policy-parameter refRlpRate reference-rate host1(config-policy-param-reference-rate)#reference-rate 100000 host1(config-policy-param-reference-rate)#exit
2. Create rate-limit profile rlpData.
   host1(config)#ip rate-limit-profile rlpData host1(config-rate-limit-profile)#committed-rate refRlpRate percentage 10 host1(config-rate-limit-profile)#committed-burst millisecond 100 host1(config-rate-limit-profile)#peak-rate refRlpRate percentage 100 host1(config-rate-limit-profile)#peak-burst millisecond 150 host1(config-rate-limit-profile)#exit
3. Create rate-limit profile rlpVoice.
   host1(config)#ip rate-limit-profile rlpVoice host1(config-rate-limit-profile)#committed-rate 64000 host1(config-rate-limit-profile)#committed-burst 100000 host1(config-rate-limit-profile)#peak-rate refRlpRate percentage 100 host1(config-rate-limit-profile)#peak-burst millisecond 150 host1(config-rate-limit-profile)#exit
4. Create rate-limit profile rlpVideo.
   host1(config)#ip rate-limit-profile rlpVideo host1(config-rate-limit-profile)#committed-rate refRlpRate percentage 70 host1(config-rate-limit-profile)#committed-burst millisecond 100 host1(config-rate-limit-profile)#peak-rate refRlpRate percentage 100 host1(config-rate-limit-profile)#peak-burst millisecond 150 host1(config-rate-limit-profile)#exit
5. Create the policy.
   host1(config)#ip policy-list P host1(config-policy)#classifier-group data host1(config-policy-classifier-group)#rate-limit-profile rlpData host1(config-policy-classifier-group)#exit host1(config-policy)#classifier-group voice host1(config-policy-classifier-group)#rate-limit-profile rlpVoice host1(config-policy-classifier-group)#exit host1(config-policy)#classifier-group video host1(config-policy-classifier-group)#rate-limit-profile rlpVideo host1(config-policy-classifier-group)#exit host1(config-policy)#exit
6. Attach IP Policy P at interface atm5/0.1.
   host1(config)#interface atm 5/0.1 host1(config-if)#ip policy-parameter reference-rate refRlpRate 1000000 host1(config-if)#ip policy input P
7. Attach IP Policy P at interface atm5/0.2 with merge.
   host1(config)#interface atm 5/0.2 host1(config-if)#ip policy input P stats enabled merge
8. Display the policy list.

       host1#show policy-list

       Policy Table

          Administrative state: enable

To configure a policy-parameter at an interface with the increase keyword:

1. Create policy list P2.
   host1(config)#ip policy-list P2 host1(config-policy)#classifier-group data2 host1(config-policy-classifier-group)#rate-limit-profile rlpData host1(config-policy-classifier-group)#exit host1(config-policy)#exit
2. Attach IP Policy P2 at interface atm5/0.2 with the merge keyword.
   host1(config)#interface atm 5/0.2 host1(config-If)#ip policy-parameter reference-rate refRlpRate 100000

   This increases from 0.

   host1(config)#ip policy-parameter reference-rate refRlpRate increase 100000

   This increases from the existing 100000.

   host1(config)#ip policy input P2 merge
3. Verify the configuration.

       host1#show policy-parameter
       Policy Parameter refRlpRate
           Type: reference-rate
           Rate: 100000
           Reference count: 7
           Referenced by interfaces: 2 references
             IP interface ATM5/0.1: 1000000
             IP interface ATM5/0.2: 200000

           Referenced by rate-limit profiles: 5 references
             rlpData
             rlpVoice
             rlpVideo
