Quality of Service (QoS) Commands

Format

diffserv

Mode

Global Config

no diffserv

This command sets the DiffServ operational mode to inactive. While disabled, the DiffServ

configuration is retained and can be changed, but it is not activated. When enabled, Diffserv

services are activated.

Format

no diffserv

Mode

Global Config

Class Commands

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

Traffic Classification

Specify Behavior Aggregate (BA), based on DSCP, and Multi-

Field (MF) classes of traffic (name, match criteria)

Service Levels

Specify the BA forwarding classes / service levels. Conceptually,

DiffServ is a two-level hierarchy of classes: 1. Service/PHB, 2.

Traffic Class

This set of commands consists of class creation/deletion and matching, with the class match

commands specifying layer 3, layer 2, and general match criteria. The class match criteria are also

known as class rules, with a class definition consisting of one or more rules to identify the traffic

belonging to the class. Note that once a class match criterion is created for a class, it cannot be

changed or deleted - the entire class must be deleted and re-created.

The CLI command root is

class-map

.

class-map

This command defines a new DiffServ class of type match-all, match-any or match-access-group.

The <

classname>

parameter is a case sensitive alphanumeric string from 1 to 31 characters

uniquely identifying the class (Note: the class name 'default' is reserved and must not be used

here).

When used without any match condition, this command enters the class-map mode. The

<

classname>

is the name of an existing DiffServ class (note: the class name 'default' is reserved

and is not allowed here)

Quality of Service (QoS) Commands

202-10088-01, March 2005

The class type of

match-all

indicates all of the individual match conditions must be true for a

packet to be considered a member of the class.

The class type of

match-any

indicates only one of the match criteria must be true for a packet to

belong to the class; multiple matching criteria are evaluated in a sequential order, with the highest

precedence awarded to the first criterion defined for the class.

The class type of

match-access-group

indicates the individual class match criteria are evaluated

based on an access list (ACL). The <

aclid>

parameter is an integer specifying an existing ACL

number (refer to the appropriate ACL documentation for the valid ACL number range). A

match-

access-group

class type copies its set of match criteria from the current rule definition of the

specified ACL number. All elements of a single ACL Rule are treated by DiffServ as a grouped

set, similar to class type all. For any class, at least one class match condition must be specified for

the class to be considered valid.

Note: The class match conditions are obtained from the referenced access list

at the time of class

creation

. Thus, any subsequent changes to the referenced ACL definition do not affect the

DiffServ class. To pick up the latest ACL definition, the DiffServ class must be deleted and re-

created.

This command may be used without specifying a class type to enter the Class-Map Config mode

for an existing DiffServ class.

Note: The CLI mode is changed to Class-Map Config when this command is successfully

executed.

Format

class-map {<match-all | match-any | match-access-

group> <aclid>} <classmapname>

Mode

Global Config

no class-map

This command eliminates an existing DiffServ class. The <

classname>

is the name of an existing

DiffServ class (note: the class name 'default' is reserved and is not allowed here). This command

may be issued at any time; if the class is currently referenced by one or more policies or by any

other class, this deletion attempt shall fail.

Format

no class-map <classname>

Mode

Global Config

class-map rename

This command changes the name of a DiffServ class. The

is the name of an existing

DiffServ class. The

parameter is a case-sensitive alphanumeric string from 1 to

31 characters uniquely identifying the class (Note: the class name ‘default’ is reserved and must

not be used here).

Default

none

Format

class-map rename <classname> <newclassname>

Mode

Global Config

match ethertype

This command adds to the specified class definition a match condition based on the value of the

ethertype. The <

ethertype>

value is specified as one of the following keywords:

appletalk, arp,

ibmsna, ipv4, ipv6, ipx, mplsmcast, mplsucast, netbios, novell, pppoe, rarp

or as a custom ethertype value in the

range of 0x0600-0xFFFF.

Format

match [not] ethertype {<keyword> | custom <0x0600-

0xFFFF>}

Mode

Class-Map Config

match secondary-cos

This command adds to the specified class definition a match condition for the secondary Class of

Service value (the inner 802.1Q tag of a double VLAN tagged packet). The value may be from 0 to

7.

Format

match [not] secondary-cos <0-7>

Mode

Class-Map Config

match secondary-vlan

This command adds to the specified class definition a match condition for the secondary VLAN

identifier value (the inner 802.1Q tag of a double VLAN tagged packet). The range from

vlanmin

and vlanmax

are integers from 1 to 4094 with vlanmax being optional.

Format

match [not] secondary-vlan <vlanmin> [<vlanmax>]

Mode

match any

This command adds to the specified class definition a match condition whereby all packets are

considered to belong to the class. The

optional [

not]

parameter has the effect of negating this match

condition for the class (i.e., none of the packets are considered to belong to the class).

Default

none

Format

match [not] any

Mode

Class-Map Config

match class-map

This command adds to the specified class definition the set of match conditions defined for another

class. The <

refclassname>

is the name of an existing DiffServ class whose match conditions are

being referenced by the specified class definition.

Note: there is no [

not

]

option for this match command.

Default

none

Format

match class-map

Mode

Class-Map Config

Restrictions

The class types of both <

classname>

and <

refclassname>

must

be identical (i.e., any vs. any, or all vs. all). A class type of acl is

not supported by this command.

Cannot specify

the same as <

classname>

(i.e.,

self-referencing of class name not allowed).

At most one other class may be referenced by a class.

Any attempt to delete the <

refclassname>

class while still refer-

enced by any <

classname

> shall fail.

The combined match criteria of <

classname>

and <

refclass-

name>

must be an allowed combination based on the class type.

Any subsequent changes to the <

refclassname>

class match cri-

teria must maintain this validity, or the change attempt shall fail.

The total number of class rules formed by the complete reference

class chain (includes both predecessor and successor classes)

must not exceed a platform-specific maximum.

In some cases, each removal of a refclass rule reduces the maxi-

mum number of available rules in the class definition by one.

no match class-map

This command removes from the specified class definition the set of match conditions defined for

another class. The <

refclassname>

is the name of an existing DiffServ class whose match conditions

are being referenced by the specified class definition. Note: there is no [

not]

option for this match

command.

Format

match cos

This command adds to the specified class definition a match condition for the Class of Service

value (the only tag in a single tagged packet or the first or outer 802.1Q tag of a double VLAN

tagged packet). The value may be from 0 to 7. The optional [

not]

parameter has the effect of

negating this match condition for the class (i.e., match all class of service values except for what is

specified here).

Default

none

Format

match [not] cos

<0-7>

Mode

Class-Map Config

match destination-address mac

This command adds to the specified class definition a match condition based on the destination

MAC address of a packet. The <macaddr>

parameter is any layer 2 MAC address formatted as six,

two-digit hexadecimal numbers separated by colons (e.g., 00:11:22:dd:ee:ff). The <

macmask>

parameter is a layer 2 MAC address bit mask, which need not be contiguous, and is formatted as

six, two-digit hexadecimal numbers separated by colons (e.g., ff:07:23:ff:fe:dc). The optional [

not]

parameter has the effect of negating this match condition for the class (i.e., match all destination

MAC addresses except for what is specified here).

Default

none

Format

match [not] destination-address mac <macaddr> <mac-

mask>
