qos map cos-traffic-class
Creates a QoS map for performing CoS-to-Traffic Class mapping.
Synopsis qos map cos-traffic-class name 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.
Command
Modes
Global configuration mode
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-class name
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
Guidelines
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
