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.

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

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
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

Verify the configuration.
