The match precedence command specifies a precedence 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 precedence 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 precedence
command in a class map, only the last command entered applies.
