4. The Structure of the MIB Modules

   There are three separate MIB modules described in this document, the
   management target MIB, the notification MIB, and the proxy MIB.  The
   following sections describe the structure of these three MIB modules.

   The use of these MIBs by particular types of applications is
   described later in this document:

   - The use of the management target MIB and the notification MIB in
     notification originator applications is described in section 5.

   - The use of the notification MIB for filtering notifications in
     notification originator applications is described in section 6.

   - The use of the management target MIB and the proxy MIB in proxy
     forwarding applications is described in section 7.

4.1. The Management Target MIB Module

   The SNMP-TARGET-MIB module contains objects for defining management
   targets.  It consists of two tables and conformance/compliance
   statements.

   The first table, the snmpTargetAddrTable, contains information about
   transport domains and addresses.  It also contains an object,
   snmpTargetAddrTagList, which provides a mechanism for grouping
   entries.

   The second table, the snmpTargetParamsTable, contains information
   about SNMP version and security information to be used when sending
   messages to particular transport domains and addresses.

   The Management Target MIB is intended to provide a general-purpose
   mechanism for specifying transport address, and for specifying
   parameters of SNMP messages generated by an SNMP entity.  It is used
   within this document for generation of notifications and for proxy
   forwarding.  However, it may be used for other purposes.  If another
   document makes use of this MIB, that document is responsible for
   specifying how it is used.  For example, [RFC2576] uses this MIB for
   source address validation of SNMPv1 messages.

4.1.1. Tag Lists

   The snmpTargetAddrTagList object is used for grouping entries in the
   snmpTargetAddrTable.  The value of this object contains a list of tag
   values which are used to select target addresses to be used for a
   particular operation.

Top      Up      ToC       Page 30 
   A tag value, which may also be used in MIB objects other than
   snmpTargetAddrTagList, is an arbitrary string of octets, but may not
   contain a delimiter character.  Delimiter characters are defined to
   be one of the following characters:

   - An ASCII space character (0x20).

   - An ASCII TAB character (0x09).

   - An ASCII carriage return (CR) character (0x0D).

   - An ASCII line feed (LF) character (0x0A).

   In addition, a tag value within a tag list may not have a zero
   length.  Generally, a particular MIB object may contain either

   - a zero-length octet string representing an empty list, or

   - a single tag value, in which case the value of the MIB object may
     not contain a delimiter character, or

   - a list of tag values, separated by single delimiter characters.

     For a list of tag values, these constraints imply certain
     restrictions on the value of a MIB object:

   - There cannot be a leading or trailing delimiter character.

   - There cannot be multiple adjacent delimiter characters.

           "An octet string containing a tag value.
            Tag values are preferably in human-readable form.

            To facilitate internationalization, this information
            is represented using the ISO/IEC IS 10646-1 character
            set, encoded as an octet string using the UTF-8
            character encoding scheme described in RFC 2279.

            Since additional code points are added by amendments
            to the 10646 standard from time to time,
            implementations must be prepared to encounter any code
            point from 0x00000000 to 0x7fffffff.

            The use of control codes should be avoided, and certain

            control codes are not allowed as described below.

            For code points not directly supported by user
            interface hardware or software, an alternative means
            of entry and display, such as hexadecimal, may be
            provided.

            For information encoded in 7-bit US-ASCII, the UTF-8
            representation is identical to the US-ASCII encoding.

            Note that when this TC is used for an object that
            is used or envisioned to be used as an index, then a
            SIZE restriction must be specified so that the number
            of sub-identifiers for any object instance does not
            exceed the limit of 128, as defined by [RFC1905].

            An object of this type contains a single tag value
            which is used to select a set of entries in a table.

            A tag value is an arbitrary string of octets, but
            may not contain a delimiter character.  Delimiter
            characters are defined to be one of the following:

                -  An ASCII space character (0x20).

                -  An ASCII TAB character (0x09).

                -  An ASCII carriage return (CR) character (0x0D).

                -  An ASCII line feed (LF) character (0x0A).

            Delimiter characters are used to separate tag values
            in a tag list.  An object of this type may only
            contain a single tag value, and so delimiter
            characters are not allowed in a value of this type.

            Note that a tag value of 0 length means that no tag is
            defined.  In other words, a tag value of 0 length would
            never match anything in a tag list, and would never
            select any table entries.

            Some examples of valid tag values are:

                - 'acme'

                - 'router'

                - 'host'

            Delimiter characters are used to separate tag values

Top      Up      ToC       Page 35 
            in a tag list.  Only a single delimiter character may
            occur between two tag values.  A tag value may not
            have a zero length.  These constraints imply certain
            restrictions on the contents of this object:

                - There cannot be a leading or trailing delimiter
                  character.

                - There cannot be multiple adjacent delimiter
                  characters.

            Some examples of valid tag lists are:

                - ''                        -- an empty list

                - 'acme'                    -- list of one tag

                - 'host router bridge'      -- list of several tags

            Note that although a tag value may not have a length of
            zero, an empty string is still valid.  This indicates
            an empty list (i.e. there are no tag values in the list).

            The use of the tag list to select table entries is
            application and MIB specific.  Typically, an application
            will provide one or more tag values, and any entry
            which contains some combination of these tag values
            will be selected."

4.2. The Notification MIB Module

   The SNMP-NOTIFICATION-MIB module contains objects for the remote
   configuration of the parameters used by an SNMP entity for the
   generation of notifications.  It consists of three tables and
   conformance/compliance statements.  The first table, the
   snmpNotifyTable, contains entries which select which entries in the
   snmpTargetAddrTable should be used for generating notifications, and
   the type of notifications to be generated.

   The second table, the snmpNotifyFilterProfileTable, sparsely augments
   the snmpTargetParamsTable with an object which is used to associate a
   set of filters with a particular management target.

   The third table, the snmpNotifyFilterTable, defines filters which are
   used to limit the number of notifications which are generated using
   particular management targets.

           "The bit mask which, in combination with the corresponding
            instance of snmpNotifyFilterSubtree, defines a family of
            subtrees which are included in or excluded from the
            filter profile.

            Each bit of this bit mask corresponds to a
            sub-identifier of snmpNotifyFilterSubtree, with the
            most significant bit of the i-th octet of this octet
            string value (extended if necessary, see below)
            corresponding to the (8*i - 7)-th sub-identifier, and
            the least significant bit of the i-th octet of this
            octet string corresponding to the (8*i)-th
            sub-identifier, where i is in the range 1 through 16.

            Each bit of this bit mask specifies whether or not
            the corresponding sub-identifiers must match when
            determining if an OBJECT IDENTIFIER matches this
            family of filter subtrees; a '1' indicates that an
            exact match must occur; a '0' indicates 'wild card',
            i.e., any sub-identifier value matches.

Top      Up      ToC       Page 52 
            Thus, the OBJECT IDENTIFIER X of an object instance
            is contained in a family of filter subtrees if, for
            each sub-identifier of the value of
            snmpNotifyFilterSubtree, either:

              the i-th bit of snmpNotifyFilterMask is 0, or

              the i-th sub-identifier of X is equal to the i-th
              sub-identifier of the value of
              snmpNotifyFilterSubtree.

            If the value of this bit mask is M bits long and
            there are more than M sub-identifiers in the
            corresponding instance of snmpNotifyFilterSubtree,
            then the bit mask is extended with 1's to be the
            required length.

            Note that when the value of this object is the
            zero-length string, this extension rule results in
            a mask of all-1's being used (i.e., no 'wild card'),
            and the family of filter subtrees is the one
            subtree uniquely identified by the corresponding
