Displaying a DSCP-to-CoS Mapping
To display the CoS value to which a specific DSCP value is mapped during
classification, use the following command:
display qos dscp-to-cos-map dscp-value
The following command displays the CoS value to which DSCP value 55 is
mapped:
WX1200# display qos dscp-to-cos-map 55
dscp 55 is classified as cos 6
Displaying a CoS-to-DSCP Mapping
To display the DSCP value to which a specific CoS value is mapped during
marking, use the following command:
display qos cos-to-dscp-map cos-value
The following command displays the DSCP value to which CoS value 6 is
mapped:
WX1200# display qos cos-to-dscp-map 6
