The following example creates 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.
switch:admin>cmsh
switch>enable
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
To activate a CoS-to-traffic class mapping, perform the following steps from Privileged EXEC mode.
1. Enter global configuration mode.
switch#configure terminal
2. Specify the 10-gigabit Ethernet interface.
switch(config)#interface intengigabitethernet 0/2
3. Activate the CoS-to-Traffic-Class mapping by name.
switch(conf-if-te-0/2)#qos cos-traffic-class test
The following example activates 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 intengigabitethernet 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
Verifying a mapping CoS-to-Traffic-Class
To verify a CoS-to-Traffic-Class mapping, perform the following steps from Privileged EXEC mode.
1. Enter global configuration mode.
switch#configure terminal
2. Verify the CoS-Traffic-Class mapping specifying a name and the mapping.
switch(config)#show qos map cos-traffic-class test
