DisplayString ::= TEXTUAL-CONVENTION
    DISPLAY-HINT "255a"

    STATUS       current
    DESCRIPTION
            "Represents textual information taken from the NVT ASCII
            character set, as defined in pages 4, 10-11 of RFC 854.

    To summarize RFC 854, the NVT ASCII repertoire specifies:

              - the use of character codes 0-127 (decimal)

              - the graphics characters (32-126) are interpreted as
                US ASCII

              - NUL, LF, CR, BEL, BS, HT, VT and FF have the special
                meanings specified in RFC 854

              - the other 25 codes have no standard interpretation

              - the sequence 'CR LF' means newline

              - the sequence 'CR NUL' means carriage-return

              - an 'LF' not preceded by a 'CR' means moving to the
                same column on the next line.

              - the sequence 'CR x' for any x other than LF or NUL is
                illegal.  (Note that this also means that a string may
                end with either 'CR LF' or 'CR NUL', but not with CR.)

    Any object defined using this syntax may not exceed 255 characters in length."

    SYNTAX       OCTET STRING (SIZE (0..255))

PhysAddress ::= TEXTUAL-CONVENTION
    DISPLAY-HINT "1x:"

    STATUS       current
    DESCRIPTION
            "Represents media- or physical-level addresses."
    SYNTAX       OCTET STRING


MacAddress ::= TEXTUAL-CONVENTION
    DISPLAY-HINT "1x:"

    STATUS       current
    DESCRIPTION
            "Represents an 802 MAC address represented in the
            `canonical' order defined by IEEE 802.1a, i.e., as if it
            were transmitted least significant bit first, even though
            802.5 (in contrast to other 802.x protocols) requires MAC
            addresses to be transmitted most significant bit first."
    SYNTAX       OCTET STRING (SIZE (6))


TruthValue ::= TEXTUAL-CONVENTION

    STATUS       current
    DESCRIPTION
            "Represents a boolean value."
    SYNTAX       INTEGER { true(1), false(2) }


TestAndIncr ::= TEXTUAL-CONVENTION

    STATUS       current
    DESCRIPTION
            "Represents integer-valued information used for atomic
            operations.  When the management protocol is used to specify
            that an object instance having this syntax is to be
            modified, the new value supplied via the management protocol
            must precisely match the value presently held by the
            instance.  If not, the management protocol set operation
            fails with an error of `inconsistentValue'.  Otherwise, if
            the current value is the maximum value of 2^31-1 (2147483647
            decimal), then the value held by the instance is wrapped to
            zero; otherwise, the value held by the instance is
            incremented by one.  (Note that regardless of whether the
            management protocol set operation succeeds, the variable-
            binding in the request and response PDUs are identical.)

    The value of the ACCESS clause for objects having this syntax is either `read-write' or `read-create'. When an instance of a columnar object having this syntax is created, any value may be supplied via the management protocol.

    When the network management portion of the system is re- initialized, the value of every object instance having this syntax must either be incremented from its value prior to the re-initialization, or (if the value prior to the re- initialization is unknown) be set to a pseudo-randomly generated value."

    SYNTAX       INTEGER (0..2147483647)


AutonomousType ::= TEXTUAL-CONVENTION

    STATUS       current
    DESCRIPTION
            "Represents an independently extensible type identification
            value.  It may, for example, indicate a particular sub-tree
            with further MIB definitions, or define a particular type of
            protocol or hardware."
    SYNTAX       OBJECT IDENTIFIER


InstancePointer ::= TEXTUAL-CONVENTION

    STATUS       obsolete
    DESCRIPTION
            "A pointer to either a specific instance of a MIB object or
            a conceptual row of a MIB table in the managed device.  In
            the latter case, by convention, it is the name of the
            particular instance of the first accessible columnar object
            in the conceptual row.

    The two uses of this textual convention are replaced by VariablePointer and RowPointer, respectively."

    SYNTAX       OBJECT IDENTIFIER


VariablePointer ::= TEXTUAL-CONVENTION

    STATUS       current
    DESCRIPTION
            "A pointer to a specific object instance.  For example,
            sysContact.0 or ifInOctets.3."
    SYNTAX       OBJECT IDENTIFIER


RowPointer ::= TEXTUAL-CONVENTION

    STATUS       current
    DESCRIPTION
            "Represents a pointer to a conceptual row.  The value is the
            name of the instance of the first accessible columnar object
            in the conceptual row.
