The match discard-class command specifies a discard class 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 discard-class 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 discard-class
command in a class map, the new values are added to the existing match statement.
The match discard-class command sets the match criteria for examining discard classes marked on the
packet. Up to eight discard class values can be matched in one match statement. For example, match
discard-class 0 1 2 3 4 5 6 7 returns matches for discard class values 0, 1, 2, 3, 4, 5, 6, and 7. Only one of the
seven values is needed to yield a match (OR operation).
