at the time of attachment. You can attach the same policy to multiple interfaces with
different parameter values.
A hierarchical rate-limit profile that contains percentage-based parameters can be
used in an external parent-group and the global default values can be changed for
each external parent group instance. The following restrictions apply:
When you attach policies that reference such same external parent group instances
to each interface, you must specify the same reference-rate policy-parameter value.
You cannot change the reference-rate policy-parameter values at interface level
when a policy attachment to the interface exists.
To configure policing, use the following steps:
Configure a policy parameter in Global Configuration mode.
1.
Assign the parameter type and global default value to a parameter.
2.
Use this policy parameter in policy objects, create a generic policy, and attach it to

multiple interfaces.
Adjust the policy parameter value for a specific interface by configuring it in Interface
4.
Configuration mode for any interface.
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.
Create policy parameter refRlpRate.
