Configure the Global Diffserv Mode
Packets are filtered and processed based on defined criteria. The filtering criteria are defined
by a class. The processing is defined by a policy's attributes. Policy attributes can 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 specifies 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.
