    MAX-ACCESS read-only
    STATUS     current
    DESCRIPTION
       "The total number of frames which were received by the probe
        and therefore not accounted for in the *StatsDropEvents, but
        for which the probe chose not to count for this entry for
        whatever reason.  Most often, this event occurs when the probe
        is out of some resources and decides to shed load from this
        collection.

        This count does not include packets that were not counted
        because they had MAC-layer errors.

        Note that, unlike the dropEvents counter, this number is the
        exact number of frames dropped."

    DESCRIPTION
        "The status of this row.

        An entry may not exist in the active state unless all

        Counters are updated in this table for every protocol type
        that is encountered when parsing a packet, but no counters are

    STATUS      current
    DESCRIPTION
        "A conceptual row in the protocolDistStatsTable.

        The index is composed of the protocolDistControlIndex of the
        associated protocolDistControlEntry followed by the
        protocolDirLocalIndex of the associated protocol that this
        entry represents.  In other words, the index identifies the
        protocol distribution an entry is a part of as well as the
        particular protocol that it represents.

        An example of the indexing of this entry is

    DESCRIPTION
        "The number of packets without errors received of this
        protocol type.  Note that this is the number of link-layer
        packets, so if a single network-layer packet is fragmented
        into several link-layer frames, this counter is incremented
        several times."

        "The number of octets in packets received of this protocol
        type since it was added to the protocolDistStatsTable
        (excluding framing bits but including FCS octets), except for
        those octets in packets that contained errors.

        protocol frames, but includes the entire packet that contained
        the protocol."

        an entry is deleted, then inserted, and then deleted, this

    MAX-ACCESS  read-write
    STATUS      current
    DESCRIPTION
        "The maximum number of entries that are desired in the
        addressMapTable. The probe will not create more than
        this number of entries in the table, but may choose to create
        fewer entries in this table for any reason including the lack
        of resources.

        If this object is set to a value less than the current number
        of entries, enough entries are chosen in an
        implementation-dependent manner and deleted so that the number
        of entries in the table equals the value of this object.

        If this value is set to -1, the probe may create any number
        of entries in this table.

        This object may be used to control how resources are allocated
        on the probe for the various RMON functions."

        "A table to control the collection of network layer address to
        physical address to interface mappings.

        Note that this is not like the typical RMON
        controlTable and dataTable in which each entry creates
        its own data table.  Each entry in this table enables the
        discovery of addresses on a new interface and the placement
        of address mappings into the central addressMapTable.

        Implementations are encouraged to add an entry per monitored
        interface upon initialization so that a default collection
        of address mappings is available."
