            Setting this object to the value invalid(2) has the effect
            of invalidating the corresponding entry in the
            ipNetToMediaTable.  That is, it effectively disassociates
            the interface identified with said entry from the mapping
            identified with said entry.  It is an implementation-
            specific matter as to whether the agent removes an
            invalidated entry from the table.  Accordingly, management
            stations must be prepared to receive tabular information
            from agents that corresponds to entries not currently in
            use.  Proper interpretation of such entries requires
            examination of the relevant ipNetToMediaType object."
