The type of mapping. Setting this object to the value invalid(2) has the effect of invalidating the corresponding entry (static entry) in the fsMIStdIpNetToPhysicalTable. That is, the agent removes the invalidated entry from the table. 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. Both of these refer to entries that provide mappings for other entities addresses. The 'local(5)' type indicates that the mapping is provided for an entity's own interface address.
