Description: The number of locally-addressed IP datagrams received successfully but discarded because of an unknown or unsupported protocol.

When tracking interface statistics, the counter of the interface to which these datagrams were addressed is incremented. This interface might not be the same as the input interface for some of the datagrams.

Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ipSystemStatsDiscontinuityTime.
