qos map cos-traffic-class

 

Creates a QoS map for performing CoS-to-Traffic Class mapping.

Synopsis

qos map cos-traffic-classname tc0 tc1 tc2 tc3 tc4 tc5 tc6 tc7

 

no qos map cos-traffic-class

Operands.

name

Specifies the CoS-to-Traffic Class QoS map name. If the named CoS-to-Traffic

 

 

Class QoS map does not exist, then it is created. If the named CoS-to-Traffic

 

 

Class QoS map already exists, then it is updated and new mappings are

 

 

automatically propagated to all interfaces bound to the QoS map.

 

tc0

Sets the Traffic Class value for all packets with outbound CoS 0.

 

tc1

Sets the Traffic Class value for all packets with outbound CoS 1.

 

tc2

Sets the Traffic Class value for all packets with outbound CoS 2.

 

tc3

Sets the Traffic Class value for all packets with outbound CoS 3.

 

tc4

Sets the Traffic Class value for all packets with outbound CoS 4.

 

tc5

Sets the Traffic Class value for all packets with outbound CoS 5.

 

tc6

Sets the Traffic Class value for all packets with outbound CoS 6.

 

tc7

Sets the Traffic Class value for all packets with outbound CoS 7.

Defaults

There are no CoS-to-Traffic Class QoS maps defined.

Description

Use this command to create a QoS map for performing CoS-to-Traffic Class mapping. A

 

CoS-to-Traffic Class QoS map takes an outbound CoS value and maps it to a Traffic Class. The

 

outbound CoS value is used as the packet user priority after applying the configured interface QoS

 

trust, interface default CoS, and CoS-to-CoS mutation policies. Traffic Class is a reference to a

 

scheduler queue and packet servicing policy. Use the no qos map cos-traffic-classname

 

command to delete the CoS-to-Traffic Class QoS map specified by the name. The CoS-to-Traffic

 

Class QoS map can only be deleted when it is not bound to any interface. All other CoS values go

 

through unchanged. This mapping matches the default behavior recommended in IEEE 802.1Q for

 

systems supporting eight Traffic Classes.

Usage

There are no usage guidelines for this command.

Examples

To create a CoS-to-Traffic Class QoS map to map CoS 0 to Traffic Class 1 and CoS 1 to Traffic Class

 

0:

 

switch(config)#qos map cos-traffic-class test 1 0 2 3 4 5 6 7

To delete a CoS-to-Traffic Class QoS map:

switch(config)#no qos map cos-traffic-class test
