10-12 CLI Commands: Differentiated Services

202-10009-01_060204

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

policy-map.

bandwidth kbps

This command identifies a minimum amount of bandwidth to be reserved for the specified class

instance within the named policy using an absolute rate notation. The committed information rate

is specified in kilobits-per-second (Kbps) and is an integer from 1 to 4294967295.

Note: The actual bandwidth allocation does not occur until the policy is attached to an interface in

a particular direction.

Note: The bandwidth kbps and percent commands are alternative ways to specify the same

bandwidth policy attribute.

Note: This command is only supported for GSM7324 and GSM7312.

Format

bandwidth kbps <1-4294967295>

Mode Policy-Class-Map Config

Restrictions The sum of the committed information rate values for all band-

width and expedite commands defined within a policy must not

exceed the available link bandwidth of the interface to which that

policy is assigned. Violation of this requirement shall prevent
