DiffServ Configuration
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.
