Policy Management Overview

Policy management enables network service providers to configure services that customize the treatment of individual packet flows received on a subscriber’s interface. The main tool for implementing policy management is a policy list. A policy list is a set of rules, each of which specifies a policy action. A rule is a policy action optionally combined with a classification.

Packets are sorted at ingress or egress into packet flows based on attributes defined in classifier control lists (CLACLs). You can apply policy lists to packets arriving and leaving an interface. You can use policy management on ATM, Frame Relay, generic routing encapsulation (GRE), IP, IPv6, Layer 2 Tunneling Protocol (L2TP), Multiprotocol Label Switching (MPLS), and virtual local area network (VLAN) traffic.

Policy management provides:

Use the SRC CLI and C-Web interface to configure policies. You configure policy components, or modules, which can be combined to implement a policy. By combining the various policy components, you can deploy a wide variety of services.
