The policy command set is used in DiffServ to define:
• Traffic Conditioning—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 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.
Class instances are always added to the end of an existing policy. While existing class instances may be
removed, their previous location in the policy is not reused, so the number of class instance additions/
removals is limited. In general, significant changes to a policy definition require that the entire policy
be deleted and re-created with the desired configuration.
The CLI command root is policy-classmap.
This command modifies the queue ID to which the associated traffic stream is assigned.
