ipNetToMediaType (1.3.6.1.2.1.4.22.1.4)

The type of mapping. 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 the entry from the mapping identified with the 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.

Additional IP objects

Following are the additional IP objects.

ipRoutingDiscards (1.3.6.1.2.1.4.23)

The number of routing entries that were selected to be discarded even though they are valid. One possible
reason for discarding such an entry could be to free up buffer space for other routing entries.
