Command Modes Interface subtype configuration mode
Description Use this command to apply a CoS-to-CoS mutation QoS map on a specific interface. Mutation
mapping is a method of modifying a QoS field in all packets on an interface. On ingress, mutation
mapping occurs before traffic classification and all other actions. On egress, mutation mapping
occurs after traffic classification and before all other actions.
Usage Guidelines The qos cos-mutation command is not available if the interface is in CEE Provisioning mode.
Enter no qos cos-mutation to remove the CoS-to-CoS mutation map.
Examples To activate a CoS-to-CoS mutation QoS map named test on a specific 40-gigabit Ethernet interface:
switch(config)# interface fortygigabitethernet 1/3/1
switch(conf-if-fo-1/3/1)# qos cos-mutation test
To remove a CoS-to-CoS mutation QoS map from a specific port-channel interface:
switch(config)# interface port-channel 22
switch(config-port-channel-22)# no qos cos-mutation
