       "To facilitate the provisioning of access control by a

       Control Model (RFC 2575, VACM) for tables in which
       multiple users may need to create or
       modify entries independently, the initial index is used as
       an 'owner index'.  Such an initial index has a syntax of
       SnmpAdminString and can thus be trivially mapped to a


       securityName or groupName defined in VACM, in
       accordance with a security policy.

       When used in conjunction with such a security policy all
       entries in the table belonging to a particular user (or
       group) will have the same value for this initial index.
       For a given user's entries in a particular table, the
       object identifiers for the information in these entries
       will have the same subidentifiers (except for the
       'column' subidentifier) up to the end of the encoded
       owner index.  To configure VACM to permit access to this
       portion of the table, one would create
       vacmViewTreeFamilyTable entries with the value of
       vacmViewTreeFamilySubtree including the owner index
       portion, and vacmViewTreeFamilyMask 'wildcarding' the

        A remote lookup operation is started when an

        occurs by setting the value of this object

        the row is created.

        A value MUST be specified for lookupCtlTargetAddress

        A remote lookup operation starts when its entry
        first becomes active(1).  Transitions in and
        out of active(1) state have no effect on the
        operational behavior of a remote lookup
        operation, with the exception that deletion of
        an entry in this table by setting its RowStatus
        object to destroy(6) will stop an active
        remote lookup operation.

        The operational state of a remote lookup operation
        can be determined by examination of its
        lookupCtlOperStatus object."

-- Lookup Results Table

 lookupResultsTable OBJECT-TYPE
    SYNTAX      SEQUENCE OF LookupResultsEntry
    MAX-ACCESS  not-accessible

    DESCRIPTION
        "Defines the Lookup Results Table for providing
        the capability of determining the results of a
        operation at a remote host.

        One or more entries are added to the
        lookupResultsTable when a lookup operation,
        as reflected by an lookupCtlEntry, is completed
        successfully.  All entries related to a
        successful lookup operation MUST be added
        to the lookupResultsTable at the same time
        that the associating lookupCtlOperStatus
        object is transitioned to completed(2).

        The number of entries added depends on the
        results determined for a particular lookup
        operation.  All entries associated with an
        lookupCtlEntry are removed when the
        lookupCtlEntry is deleted.

        A remote host can be multi-homed and have more than one IP
        address associated with it (returned by lookup function),
        or it can have more than one symbolic name (returned
        by lookup function).

        A function such as, for example, getnameinfo() or
        gethostbyaddr() is called with a host address as its
        parameter and is used primarily to determine a symbolic
        name to associate with the host address.  Entries in the
        lookupResultsTable MUST be made for each host name
        returned.  If the function identifies an 'official host
        name,' then this symbolic name MUST be assigned a
        lookupResultsIndex of 1.

        A function such as, for example, getaddrinfo() or
        gethostbyname() is called with a symbolic host name and is
        used primarily to retrieve a host address.  The entries


        MUST be stored in the order that they are retrieved from
