Description: The type of mapping.

Setting this object to the value invalid(2) has the effect of invalidating the corresponding entry in the cInetNetToMediaTable. 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 cInetNetToMediaType object.

The 'dynamic(3)' type indicates that the IP address to physical addresses mapping has been dynamically resolved using e.g. IPv4 ARP or the IPv6 Neighbor Discovery protocol.

The 'static(4)' type indicates that the mapping has been statically configured. The 'local(5)' type indicates that the mapping is provided for an entity's own interface address.
