Queue color-to-dscp map profile configuration
Configuration queue-color-to-dscp
The following steps describe how to configure queue-color-to-dscp map profile.
#configure terminal | Enter configure mode. |
(config)#qos enable | Enable QoS globally. |
(config)#qos statistics | Enable QoS statistics. |
(config)#qos remark dscp | Configure QOS remark DSCP in global configuration mode |
(config)#qos profile queue-color-to-dscp Profile6 | Enter queue-color-to-dscp profile configuration mode |
(config-egress-dscp-map)#queue 3 color green dscp 48 | Map queue 3 to dscp 48 for green color traffic under queue-color-to-dscp profile configuration mode |
(config-egress-dscp-map)#exit | Exit queue-color-to-dscp map configuration mode |
(config)#qos profile queue-color-to-dscp default | Enter queue-color-to-dscp default map profile configuration mode |
(config-egress-dscp-map)#queue 5 dscp 32 | Map queue 5 frames to dscp 32 |
(config-egress-cos-map)#exit | Exit queue-color-to-dscp configuration mode |
(config)#commit | Committing the configured line |
(config)#exit | Exit configure mode. |

Configuration of Queue-color-to-dscp Map Profile on Interface mode
The following steps describe how to configure Queue-color-to-dscp map profile on interface mode.
#configure terminal | Enter configure mode. |
(config)#qos enable | Enable QoS globally. |
(config)#qos statistics | Enable QoS statistics. |
(config)#interface xe2 | Enter interface mode. |
(config-if)#switchport | Configure the port as switchport |
(config-if)#qos map-profile queue-color-to-dscp Profile6 | map queue-color-to-dscp profile on the interface |
(config-if)#qos remark dscp disable | Disable QoS remark for DSCP on interface level |
(config-if)#exit | Exit interface mode. |
(config)#commit | Committing the configured line |
(config)#exit | Exit configure mode. |
Note: When QoS remark for DSCP is disabled on interface level, it will only change queue, CoS value won't be changed. If qos remark dscp enable is configured on interface level, DSCP value is altered accordingly. By default, qos remark dscp is enabled on interface level.
