The match dscp command specifies a DSCP value that is used as the match criteria against which packets
are checked to determine if they belong to the class specified by the class map.
To use the match dscp command, you must first enter the class-map command to specify the name of the
class whose match criteria you want to establish. If you specify more than one match dscp command in a
class map, only the last command entered applies.
