Defining Policies
A policy is a collection of classes, each of which is a combination of a class map and a QoS action to apply to
matching traffic. Classes are applied in a first-fit manner within a policy.
Before configuring policies for classes whose match criteria are defined in a class map, a class map must first be
defined, or the name of the policy map to be created, added to, or modified must first be specified. Class policies
can be configured in a policy map only if the classes have defined match criteria.
An aggregate policer can be applied to multiple classes in the same policy map, but an aggregate policer cannot
be used across different policy maps. Define an aggregate policer if the policer is shared with multiple classes.
policers in one port cannot be shared with other policers in another device. Traffic from two different ports can be
aggregated for policing purposes. To define policies:
