   SnmpEngineID ::= TEXTUAL-CONVENTION
       STATUS       current
       DESCRIPTION "An SNMP engine's administratively-unique identifier.
                    Objects of this type are for identification, not for
                    addressing, even though it is possible that an
                    address may have been used in the generation of
                    a specific value.

                    The value for this object may not be all zeros or
                    all 'ff'H or the empty (zero length) string.

                    The initial value for this object may be configured
                    via an operator console entry or via an algorithmic
                    function.  In the latter case, the following
                    example algorithm is recommended.

                    In cases where there are multiple engines on the
                    same system, the use of this algorithm is NOT
                    appropriate, as it would result in all of those
                    engines ending up with the same ID value.

                    1) The very first bit is used to indicate how the
                       rest of the data is composed.

                       0 - as defined by enterprise using former methods
                           that existed before SNMPv3. See item 2 below.

                       1 - as defined by this architecture, see item 3
                           below.

                       Note that this allows existing uses of the
                       engineID (also known as AgentID [RFC1910]) to
                       co-exist with any new uses.

                    2) The snmpEngineID has a length of 12 octets.

                       The first four octets are set to the binary
                       equivalent of the agent's SNMP management
                       private enterprise number as assigned by the
                       Internet Assigned Numbers Authority (IANA).
                       For example, if Acme Networks has been assigned
                       { enterprises 696 }, the first four octets would
                       be assigned '000002b8'H.

                       The remaining eight octets are determined via
                       one or more enterprise-specific methods. Such
                       methods must be designed so as to maximize the
                       possibility that the value of this object will
                       be unique in the agent's administrative domain.
                       For example, it may be the IP address of the SNMP
                       entity, or the MAC address of one of the
                       interfaces, with each address suitably padded
                       with random octets.  If multiple methods are
                       defined, then it is recommended that the first
                       octet indicate the method being used and the
                       remaining octets be a function of the method.

                    3) The length of the octet strings varies.

                       The first four octets are set to the binary
                       equivalent of the agent's SNMP management
                       private enterprise number as assigned by the
                       Internet Assigned Numbers Authority (IANA).
                       For example, if Acme Networks has been assigned
                       { enterprises 696 }, the first four octets would
                       be assigned '000002b8'H.

                       The very first bit is set to 1. For example, the
                       above value for Acme Networks now changes to be
                       '800002b8'H.

                       The fifth octet indicates how the rest (6th and
                       following octets) are formatted. The values for
                       the fifth octet are:

                         0     - reserved, unused.

                         1     - IPv4 address (4 octets)
                                 lowest non-special IP address

                         2     - IPv6 address (16 octets)
                                 lowest non-special IP address

                         3     - MAC address (6 octets)
                                 lowest IEEE MAC address, canonical
                                 order

                         4     - Text, administratively assigned
                                 Maximum remaining length 27

                         5     - Octets, administratively assigned
                                 Maximum remaining length 27

                         6-127 - reserved, unused

                       127-255 - as defined by the enterprise

   SnmpSecurityModel ::= TEXTUAL-CONVENTION
       STATUS       current
       DESCRIPTION "An identifier that uniquely identifies a
                    securityModel of the Security Subsystem within the
                    SNMP Management Architecture.

                    The values for securityModel are allocated as
                    follows:

                    - The zero value is reserved.
                    - Values between 1 and 255, inclusive, are reserved
                      for standards-track Security Models and are
                      managed by the Internet Assigned Numbers Authority
                      (IANA).
                    - Values greater than 255 are allocated to
                      enterprise-specific Security Models.  An
                      enterprise-specific securityModel value is defined
                      to be:

                      enterpriseID * 256 + security model within
                      enterprise

                      For example, the fourth Security Model defined by
                      the enterprise whose enterpriseID is 1 would be
                      260.

                    This scheme for allocation of securityModel
                    values allows for a maximum of 255 standards-
                    based Security Models, and for a maximum of
                    255 Security Models per enterprise.

                    It is believed that the assignment of new
                    securityModel values will be rare in practice
                    because the larger the number of simultaneously
                    utilized Security Models, the larger the
                    chance that interoperability will suffer.
                    Consequently, it is believed that such a range
                    will be sufficient.  In the unlikely event that
                    the standards committee finds this number to be
                    insufficient over time, an enterprise number
                    can be allocated to obtain an additional 255
                    possible values.

                    Note that the most significant bit must be zero;
                    hence, there are 23 bits allocated for various
                    organizations to design and define non-standard
                    securityModels.  This limits the ability to
                    define new proprietary implementations of Security
                    Models to the first 8,388,608 enterprises.

                    It is worthwhile to note that, in its encoded
                    form, the securityModel value will normally
                    require only a single byte since, in practice,
                    the leftmost bits will be zero for most messages
                    and sign extension is suppressed by the encoding
                    rules.

                    As of this writing, there are several values
                    of securityModel defined for use with SNMP or
                    reserved for use with supporting MIB objects.
                    They are as follows:

                        0  reserved for 'any'
                        1  reserved for SNMPv1
                        2  reserved for SNMPv2c

                           messageProcessingModel within enterprise

                      For example, the fourth Message Processing Model
                      defined by the enterprise whose enterpriseID
                      is 1 would be 260.

                    This scheme for allocating messageProcessingModel
                    values allows for a maximum of 255 standards-

   SnmpAdminString ::= TEXTUAL-CONVENTION
       DISPLAY-HINT "255a"
       STATUS       current
       DESCRIPTION "An octet string containing administrative
                    information, 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 transformation format
                    described in [RFC2279].

                    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.  Byte sequences that do not
                    correspond to the valid UTF-8 encoding of a
                    code point or are outside this range are
                    prohibited.

                    The use of control codes should be avoided.

                    When it is necessary to represent a newline,
                    the control code sequence CR LF should be used.

                    The use of leading or trailing white space should
                    be avoided.

                    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 encoding is identical to the
                    US-ASCII encoding.

                    UTF-8 may require multiple bytes to represent a
                    single character / code point; thus the length
                    of this object in octets may be different from
                    the number of characters encoded.  Similarly,
                    size constraints refer to the number of encoded
                    octets, not the number of characters represented
                    by an 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].

                    Note that the size of an SnmpAdminString object is
                    measured in octets, not characters.
