5.20.3. Policy commands
The 'policy' command set is used in DiffServ to define:
Traffic Classification Specify traffic conditioning actions (policing, marking, shaping) to apply to traffic
classes.
Service Provisioning Specify bandwidth and queue depth management requirements of service levels (EF,
AF, etc.).
The policy commands are used to associate a traffic class, which was defined by the class command set, with
one or more QoS policy attributes. This association is then assigned to an interface in a particular direction to
form a service. The user specifies the policy name when the policy is created.
The DiffServ CLI does not necessarily require that users associate only one traffic class to one policy. In fact,
multiple traffic classes can be associated with a single policy, each defining a particular treatment for packets
that match the class definition. When a packet satisfies the conditions of more than one class, preference is
based on the order in which the classes were added to the policy, with the foremost class taking highest
precedence.
This set of commands consists of policy creation/deletion, class addition/removal, and individual policy
attributes. Note that the only way to remove an individual policy attribute from a class instance within a policy is
to remove the class instance and re-add it to the policy. The values associated with an existing policy attribute
can be changed without removing the class instance.
The CLI command root is policy-map.
