Table 17 presents the Layer 2 CoS user priority generation table conforming to 802.1Q default
mapping. You can override this default user priority table per port if you want to change (mutate)
the COS value.
Configuring the QoS trust
Example of setting the QoS trust on a 10-Gigabit Ethernet 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 trust cos
switch(conf-if-te-0/2)#exit
switch(config)#exit
