Policy Commands

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 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

config diffserv policy.

config diffserv policy create

This command establishes a new DiffServ policy. The <policyname> parameter is a case-sensitive

alphanumeric string from 1 to 31 characters uniquely identifying the policy. The type of policy is

specific to either the inbound or outbound traffic direction as indicated by the

<in/out> parameter.
