Once the traffic class mapping has been resolved for ingress traffic, it is applied consistently
across all queueing incurred on the ingress and egress ports.
across all queueing incurred on the ingress and egress ports.
Mapping CoS-to-Traffic-Class
Perform the following steps from Privileged EXEC mode to map a CoS-to-Traffic-Class.
1. Enter global configuration mode.
switch#configure terminal
2. Create the CoS-Traffic-Class mapping by specifying a name and the mapping.
switch(config)#qos map cos-traffic-class test 1 0 2 3 4 5 6 7
Example of creating CoS-to-Traffic-Class QoS map to map CoS 0 (best effort) to Traffic Class 1 and CoS 1 to
below best effort Traffic Class 0, all other CoS go through unchanged. This mapping matches the default
behavior recommended in IEEE 802.1Q for systems supporting 8 Traffic Classes.
below best effort Traffic Class 0, all other CoS go through unchanged. This mapping matches the default
behavior recommended in IEEE 802.1Q for systems supporting 8 Traffic Classes.

switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)#qos map cos-traffic-class test 1 0 2 3 4 5 6 7
switch(config)#end
switch#
3. Enter the copy command to save the running-config file to the startup-config file.
switch#copy running-config startup-config
Activating a mapping CoS-to-Traffic-Class
Perform the following steps from Privileged EXEC mode to activate a CoS-to-traffic class mapping.
1. Enter global configuration mode.
switch#configure terminal
2. Specify the 10-gigabit Ethernet interface.
Example of selecting the 10-Gigabit Ethernet interface port 0/2.
switch(config)#interface tengigabitethernet 0/2
3. Activate the CoS-to-Traffic-Class mapping by name.
switch(conf-if-te-0/2)#qos cos-traffic-class test
Example of activating the CoS-to-Traffic-Class QoS map on an interface.
switch:admin>cmsh
switch>enable
switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)#interface tengigabitethernet 0/2
switch(conf-if-te-0/2)#qos cos-traffic-class test
switch(conf-if-te-0/2)#exit
switch(config)#end
switch#
4. Enter the copy command to save the running-config file to the startup-config file.
switch#copy running-config startup-config
