Purpose
Enters global configuration mode.

qos-policy-map-name, and then enters policy-map mode.
The policy-map name can contain alphabetic, hyphen, or
underscore characters, is case sensitive, and can be up to
40 characters.
Creates a reference to class-map-name, and enters
policy-map class configuration mode. The class is added
to the end of the policy map unless insert-before is used
to specify the class to insert before. Use the class-default
keyword to select all traffic that is not currently matched
by classes in the policy map.
Sets the CoS value to cos-value. The value can range from
0 to 7.
