Quality of Service (QoS) Commands

11-29

202-10088-01, March 2005

Note:

Queue depth management defaults to tail drop, but the randomdrop command can be used

to change to a RED scheme.

Format

shape peak <1-4294967295> <1-4294967295>

Mode

Policy-classmap Config

Restrictions

Neither of the shaping rate parameters is allowed to exceed the

maximum link data rate of the interface to which the policy is

applied.

Policy Type

Out

Incompatibilities

Expedite (all forms)

Service Commands

The 'service' command set is used in DiffServ to define:

Traffic Conditioning

Assign a DiffServ traffic conditioning policy (as specified by the

policy commands) to an interface in the incoming direction

Service Provisioning

Assign a DiffServ service provisioning policy (as specified by the

policy commands) to an interface in the outgoing direction

The service commands attach a defined policy to a directional interface. Only one policy may be

assigned at any one time to an interface in a particular direction. The policy type (in, out) must

match the interface direction to which it is attached.

This set of commands consists of service addition/removal.

The CLI command root is

service-policy

This command attaches a policy to an interface in a particular direction. The command can be used

in the

Interface Config

mode to attach a policy to a specific interface. Alternatively, the command

can be used in the

Global Config

mode to attach this policy to all system interfaces. The direction

value is either in or out. The <

policyname>

parameter is the name of an existing DiffServ policy,

whose type must match the interface direction. Note that this command causes a service to create a

reference to the policy.

Note:

This command effectively enables DiffServ on an interface (in a particular direction). There

is no separate interface administrative 'mode' command for DiffServ.

Quality of Service (QoS) Commands

202-10088-01, March 2005

Note:

This command shall fail if any attributes within the policy definition exceed the capabilities

of the interface. Once a policy is successfully attached to an interface, any attempt to change the

policy definition such that it would result in a violation of said interface capabilities shall cause the

policy change attempt to fail.

Format

service-policy <in | out> <policymapname>

Modes

Global Config (for all system interfaces)

Interface Config (for a specific interface)

Restrictions

Only a single policy may be attached to a particular interface in a

particular direction at any one time.

no service-policy

This command detaches a policy from an interface in a particular direction. The command can be

used in the Interface Config mode to detach a policy from a specific interface. Alternatively, the

command can be used in the Global Config mode to detach this policy from all system interfaces

to which it is currently attached. The direction value is either in or out. The <

policyname>

parameter is the name of an existing DiffServ policy. Note that this command causes a service to

remove its reference to the policy.

Note:

This command effectively disables DiffServ on an interface (in a particular direction).

There is no separate interface administrative 'mode' command for DiffServ.

Format

no service-policy <in | out> <policymapname>

Modes

Global Config (for all system interfaces)

Interface Config (for a specific interface)

Show Commands

The 'show' command set is used in DiffServ to display configuration and status information for:

•

Classes

•

Policies

•

Services

This information can be displayed in either summary or detailed formats. The status information is

only shown when the DiffServ administrative mode is enabled; it is suppressed otherwise.

There is also a 'show' command for general DiffServ information that is available at any time.

show class-map

This command displays all configuration information for the specified class. The

is

the name of an existing DiffServ class.

Format

show class-map

Mode

Privileged EXEC and User EXEC

If the Class Name is specified the following fields are displayed:

Class Name

The name of this class.

Class Type

The class type (all, any, or acl) indicating how the match criteria

are evaluated for this class. A class type of all means every match

criterion defined for the class is evaluated simultaneously they

must all be true to indicate a class match. For a type of any each

match criterion is evaluated sequentially and only one need be

true to indicate a class match. Class type acl rules are evaluated in

a hybrid manner, with those derived from each ACL Rule

grouped and evaluated simultaneously, while each such grouping

is evaluated sequentially.

Match Criteria

The Match Criteria fields will only be displayed if they have been

configured. They will be displayed in the order entered by the

user. These are evaluated in accordance with the class type. The

possible Match Criteria fields are: Class of Service, Destination

IP Address, Destination Layer 4 Port, Destination MAC Address,

Every, IP DSCP, IP Precedence, IP TOS, Protocol Keyword, Ref-

erence Class, Source IP Address, Source Layer 4 Port, Source

MAC Address, COS,

Secondary COS

, and VLAN,

Secondary

VLAN, and Ethertype

.

Values

This field displays the values of the Match Criteria.

Excluded

This field indicates whether or not this Match Criteria is

excluded.

If the Class Name is not specified, this command displays a list of all defined DiffServ classes. The

following fields are displayed:

Class Name

The name of this class. (Note that the order in which classes are

displayed is not necessarily the same order in which they were

created.)

Class Type

The class type (all, any, or acl) indicating how the match cri-

teria are evaluated for this class. A class type of all means

every match criterion defined for the class is evaluated simul-

taneously they must all be true to indicate a class match.For a

type of any each match criterion is evaluated sequentially and

only one need be true to indicate a class match. Class type acl

rules are evaluated in a hybrid manner, with those derived

from each ACL Rule grouped and evaluated simultaneously,

while each such grouping is evaluated sequentially.

ACL Number

The ACL number used to define the class match conditions

at the time the class was created. This field is only meaning-

ful if the class type is acl. (Note that the contents of the ACL

may have changed since this class was created.)

Ref Class Name

The name of an existing DiffServ class whose match con-

ditions are being referenced by the specified class definition.

show diffserv

This command displays the DiffServ General Status Group information, which includes the

current administrative mode setting as well as the current and maximum number of rows in each of

the main DiffServ private MIB tables. This command takes no options.

Format

show diffserv

Mode

Privileged EXEC

DiffServ Admin mode

Class Table Size

The current number of entries (rows) in the Class Table.

Class Table Max

The maximum allowed entries (rows) for the Class Table.

Class Rule Table Size

The current number of entries (rows) in the Class Rule Table.

Class Rule Table Max

Table.

is the name of an existing DiffServ policy.

Format

show policy-map

[policyname]

Mode

Policy-classmap Config

Mark Secondary COS

Denotes the secondary class of service value that is set in the

802.1p header of outbound packets. This is not displayed if the

mark secondary-cos was not specified.

Conform COS

The action to be taken on conforming packets per the policing

metrics.

Conform Secondary COS

The action to be taken on packets conforming with the second-

ary class of service value per the policing metrics.

Exceed COS

Exceed Secondary COS

The action to be taken on excess packets conforming with the

secondary class of service value per the policing metrics.

Non-Conform COS

The action to be taken on violating packets per the policing met-

ric.

Non-Conform Secondary COS

The action to be taken on violating packets conforming

with the secondary class of service per the policing metric.

Assign Queue

Directs traffic stream to the specified QoS queue.

This allows a

traffic classifier to specify which one of the supported hardware

queues are used for handling packets belonging to the class.

Drop

Drop a packet upon arrival.

This is useful for emulating access

control list operation using DiffServ, especially when DiffServ

and ACL cannot co-exist on the same interface.

Redirect

Forces a classified traffic stream to a specified egress port (physi-

cal or LAG).

This can occur in addition to any marking or polic-

Rate
