Quality of Service (QoS) Commands

11-19

202-10088-01, March 2005

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

.

assign-queue

This command modifies the queue id to which the associated traffic stream is assigned. The

queueid is an integer from 0 to n-1, where n is the number of egress queues supported by the

device.

Format

assign-queue <queueid>

Mode

Policy-Class-Map Config

drop

This command specifies that all packets for the associated traffic stream are to be dropped at

ingress.

Format

drop

Mode

Policy-Class-Map Config

mark secondary-cos

This command marks all packets for the associated traffic stream with the specified secondary

class of service value (the inner 802.1Q tag of a double VLAN tagged packet) in the priority field

of the 802.1p header. If the packet does not already contain this header, one is inserted. The CoS

value is an integer from 0 to 7.

Format

mark secondary-cos <0-7>

Mode

Policy-Class-Map Config

redirect

This command specifies that all incoming packets for the associated traffic stream are redirected to

a specific egress interface (physical port or port-channel).

Format

redirect <slot/port>

Mode

Policy-Class-Map Config

conform-color

This command is used to enable color-aware traffic policing and define the conform-color and

exceed-color class maps used. Used in conjunction with the police command where the fields for

the conform level (for simple, single-rate, and two-rate policing) and optionally the exceed level

(for single-rate and two-rate policing) are specified. The <

class-map-name

> parameter is the

name of an existing Diffserv class map, where different ones must be used for the conform and

exceed colors.

Format

conform-color <class-map-name> [exceed-color <class-

map-name>]

Mode

Policy-Class-Map Config

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.

Format

bandwidth kbps <1-4294967295>

Mode

Policy-classmap 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

successful attachment of a policy to the interface, or shall cause

this command to fail if the policy is already in service on one or

more interfaces.

Expedite (all forms)

bandwidth percent

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

instance within the named policy using a relative rate notation. The committed information rate is

specified as a percentage of total link capacity and is an integer from 1 to 100.

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.

Format

bandwidth percent <1-100>

Mode

Policy-classmap 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

successful attachment of a policy to the interface, or shall cause

this command to fail if the policy is already in service on one or

more interfaces.

Expedite (all forms)

class

This command creates an instance of a class definition within the specified policy for the purpose

of defining treatment of the traffic class through subsequent policy attribute statements. The

<

classname>

is the name of an existing DiffServ class. Note that this command causes the

specified policy to create a reference to the class definition.

Note:

The CLI mode is changed to Policy-classmap Config when this command is successfully

executed.

Format

class <classname>

no class

This command deletes the instance of a particular class and its defined treatment from the

specified policy. <

classname>

is the names of an existing DiffServ class. Note that this command

removes the reference to the class definition for the specified policy.

Format

no class <classname>

Policy-Map Config

expedite kbps

This command identifies the maximum guaranteed 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.

The optional committed burst size is specified in kilobytes (KB) as an integer from 1 to 128, with

a default of 4.

Note:

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

a particular direction.

Note:

The expedite kbps and percent commands are alternative ways to specify the same expedite

policy attribute.

Format

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

width and expedite commands defined within a policy must not

this command to fail if the policy is already in service on one or

expedite percent

This command identifies the maximum guaranteed amount of bandwidth to be reserved for the

specified class instance within the named policy using a relative rate notation. The committed

information rate is specified as a percentage of total link capacity and is an integer from 1 to 100.
