2. Policy - Create policies, associate classes with policies, and define policy statements.

Packets are classified and processed based on defined criteria. The classification criteria is
defined by a class. The processing is defined by a policy's attributes. Policy attributes may be
defined on a per-class instance basis, and it is these attributes that are applied when a match
occurs. A policy can contain multiples classes. When the policy is active, the actions taken
depend on which class matches the packet.
Packet processing begins by testing the class match criteria for a packet. A policy is applied
to a packet when a class match within that policy is found.
