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

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
