Setting this object to the value invalid(2) has the effect of invalidating the corresponding entry in the nwDecIVHostMapTable. That is, it effectively dissasociates the circuitand/or 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 inter- pretation of such entries requires examination of the relevant wDecIVHostMapType object.
