4.5.4 Differentiated Services
Packets are filtered and processed based on defined criteria. The filtering 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.
The configuration process begins with defining one or more match criteria for a class. Then one or more classes are added to a
policy. Policies are then added to interfaces.
Packet processing begins by testing the match criteria for a packet. The 'all' class type option defines that each match criteria
within a class must evaluate to true for a packet to match that class. The 'any' class type option defines that at least one match
criteria must evaluate to true for a packet to match that class. Classes are tested in the order in which they were added to the
policy. A policy is applied to a packet when a class match within that policy is found.
