qos cos-traffic-class

Applies a Quality of Service (QoS) CoS-to-traffic class mutation map on an interface.

Syntax

qos cos-traffic-class cos_map_name

Command Default

No explicit QoS CoS-to-traffic class mutation map is applied; the inbound CoS equals the outbound CoS.

Parameters

cos_tc_map_name: The name of the CoS-to-traffic class mutation map.

Modes

Interface configuration mode.

Usage Guidelines

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.

Examples

To activate a QoS CoS-to-traffic class mutation map named cosMutMap on a specific Ethernet interface:

device# configure terminal
device(config)# interface ethernet 1/3 
device(conf-if-eth-1/3)# qos cos-mutation cosMutMap

To activate a QoS CoS-to-traffic class mutation map from a specific port channel interface:

device# configure terminal
device(config)# interface port-channel 22 
device(config-port-channel-22)# qos cos-mutation cosMutMap
