decimal values are 0 to 63. To specify a range, use the following
format: 40-56. Specify the lower number first.
cos level — Internal QoS value. You can specify a number from
0to7.
Defaults — The defaults are listed by the display qos command.

History —Introduced in MSS Version 4.1.
Examples — The following command maps DSCP values 40-56 to
internal CoS value 6:
WX1200# set qos dscp-to-cos-map 40-56 cos 6
warning: cos 5 is marked with dscp 63 which will be
classified as cos 7
warning: cos 7 is marked with dscp 56 which will be
classified as cos 6
As shown in this example, if the change results in a change to CoS, MSS
displays a warning message indicating the change.
