nlHostOutMacNonUnicastPkts OBJECT-TYPE

    DESCRIPTION
        "The number of packets without errors transmitted by this
        address that were directed to any MAC broadcast addresses
        or to any MAC multicast addresses since this host was
        added to the nlHostTable.  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."

hlMatrixControlTable OBJECT-TYPE
    SYNTAX      SEQUENCE OF HlMatrixControlEntry
    MAX-ACCESS  not-accessible
    STATUS      current
    DESCRIPTION
        "A list of higher-layer (i.e., non-MAC) matrix control entries.

        These entries will enable the collection of the network- and
        application-level matrix tables containing conversation
        statistics indexed by pairs of network addresses.
        Both the network- and application-level matrix tables are
        controlled by this table so that they will both be created
        and deleted at the same time, further increasing the ease with
        which they can be implemented as a single datastore.  (Note that
        if an implementation stores application-layer matrix records

Top      Up      ToC       Page 48 
        in memory, it can derive network-layer matrix records from
        them.)

        Entries in the nlMatrixSDTable and nlMatrixDSTable will be
        created on behalf of each entry in this table.  Additionally,
        if this probe implements the alMatrix tables, entries in the
        alMatrix tables will be created on behalf of each entry in
        this table."
