Policies dynamically control how an MPE device processes protocol messages as they pass through it. Using these rules, you can define how and when network resources are utilized by subscribers. For example, when the MPE device receives a request to establish a session with a certain quality of service (QoS) level, you can use a policy rule to approve the request as is, to reject the request, or to make changes in the request before it is forwarded to the intended destination as a network element.
This chapter describes how policies are structured and used within the CMP system. To create policy rules or groups, see Managing Policy Rules or Managing Policy Groups, respectively.
Before reading this chapter, you should have a basic understanding of the CMP interface. For a discussion of the CMP interface and the terminology used to describe it, see CMP Interface Overview.
