  22. Abstract
  23.  
  24.    This memo defines a portion of the Management Information Base (MIB)
  25.    for use with network management protocols in TCP/IP-based internets.
  26.    In particular, it defines objects for managing the Packet Layer of
  27.    X.25.  The objects defined here, along with the objects in the "SNMP
  28.    MIB Extension for LAPB" [9] and the "Definitions of Managed Objects
  29.    for RS-232-like Hardware Devices" [8], combine to allow management of
  30.    an X.25 protocol stack.

  67. 1.  The Network Management Framework
  68.  
  69.    The Internet-standard Network Management Framework consists of three
  70.    components.  These components give the rules for defining objects,
  71.    the definitions of objects, and the protocol for manipulating
  72.    objects.
  73.  
  74.    The network management framework structures objects in an abstract
  75.    information tree. The branches of the tree name objects and the
  76.    leaves of the tree contain the values manipulated to effect
  77.    management. This tree is called the Management Information Base or
  78.    MIB. The concepts of this tree are given in STD 16/RFC 1155, "The
  79.    Structure of Management Information" or SMI [1]. The SMI defines the
  80.    trunk of the tree and the types of objects used when defining the
  81.    leaves. STD 16/RFC 1212, "Towards Concise MIB Definitions" [4],
  82.    defines a more concise description mechanism that preserves all the
  83.    principals of the SMI.
  84.  
  85.    The core MIB definitions for the Internet suite of protocols can be
  86.    found in RFC 1156 [2] "Management Information Base for Network
  87.    Management of TCP/IP-based internets". STD 17/RFC 1213 [5] defines
  88.    MIB-II, an evolution of MIB-I with changes to incorporate
  89.    implementation experience and new operational requirements.
  90.  
  91.    STD 15/RFC 1157 [3] defines the SNMP protocol itself. The protocol
  92.    defines how to manipulate the objects in a remote MIB.
  93.  
  94.    The tree structure of the MIB allows new objects to be defined for
  95.    the purpose of experimentation and evaluation.
  96.  
  97. 2.  Objects
  98.  
  99.    The definition of an object in the MIB requires an object name and
  100.    type.  Object names and types are defined using the subset of
  101.    Abstract Syntax Notation One (ASN.1) [6] defined in the SMI [1].
  102.    Objects are named using ASN.1 object identifiers, administratively
  103.    assigned names, to specify object types.  The object name, together
  104.    with an optional object instance, uniquely identifies a specific
  105.    instance of an object.  For human convenience, we often use a textual
  106.    string, termed the OBJECT DESCRIPTOR, to also refer to objects.
  107.  
  108.    Objects also have a syntax that defines the abstract data structure
  109.    corresponding to that object type.  The ASN.1 language [6] provides
  110.    the primitives used for this purpose.  The SMI [1] purposely
  111.

  119.    restricts the ASN.1 constructs which may be used for simplicity and
  120.    ease of implementation.  The encoding of an object type simply
  121.    describes how to represent an object using ASN.1 encoding rules [7],
  122.    for purposes of dealing with the SNMP protocol.
  123.  
  124. 2.1.  Format of Definitions
  125.  
  126.    Section 4 contains the specification of all object types defined in
  127.    this MIB module.  The object types are defined using the conventions
  128.    defined in the SMI, as amended by the extensions specified in
  129.    "Towards Concise MIB Definitions" [4].
  130.  
  131. 3.  Overview
  132.  
  133. 3.1.  Informal Overview
  134.  
  135.    This section describes how the objects defined below relate with
  136.    other MIBs.  This section is only informational to help understand
  137.    how the pieces fit together.
  138.  
  139.    The objects defined below are used in conjunction with MIB-II and
  140.    other MIBs such as the LAPB MIB [9].  A system with a complete X.25
  141.    stack running over a synchronous line will have at least two
  142.    interfaces in the ifTable defined in MIB-II.  There will be an
  143.    interface for LAPB and another interface for the packet layer of
  144.    X.25. There will also be objects defined in the RS-232-like MIB for
  145.    the physical sync line.
  146.  
  147.    Each software interface identifies the layer below it used to send
  148.    and receive packets. The X.25 MIB object, defined below,
  149.    x25OperDataLinkId, specifies an instance of lapbAdmnIndex for the
  150.    LAPB interface under that X.25. The LAPB object, lapbOperPortId,
  151.    identifies an instance of the rs232PortIndex for the the Sync line
  152.    used by LAPB.
  153.  
  154.    For X.25 running over LAPB over Ethernet, the lapbOperPortId would
  155.    identify the instance of ifIndex for the Ethernet interface.
  156.  
  157.    Each X.25 subnetwork will have separate entries in the ifTable.  Thus
  158.    a system with two X.25 lines would have two ifTable entries for the
  159.    two X.25 packet layers and two other entries for the two LAPB
  160.    interfaces. Each X.25 Packet Layer MIB would identify the instance of
  161.    the LAPB MIB for the interface below it. Each LAPB MIB would identify
  162.    the Sync line below it. The system would also have two entries in the
  163.    rs232PortTable and rs232SyncPortTable for the two physical lines.
  164.  
  165.    Since the ifTable as defined in MIB-II is device independent, it
  166.    doesn't have anything specific for any type of interface.  The

  173.  
  174.  
  175.    objects below define the X.25 packet layer specific information for
  176.    an interface of type X.25. Different X.25 interfaces can also be
  177.    differentiated by matching the values of ifIndex with x25AdmnIndex.
  178.  
  179. 3.2.  Textual Conventions
  180.  
  181.    This MIB introduces a new data type as a textual convention for use
  182.    with X.25.  This textual convention enhances the readability of the
  183.    specification and can ease comparison with other specifications if
  184.    appropriate.  It should be noted that the introduction of such
  185.    textual conventions has no effect on either the syntax nor the
  186.    semantics of any managed objects.  These conventions are merely an
  187.    artifact of the explanatory method used.  Objects defined in terms of
  188.    one of these methods are always encoded by means of the rules that
  189.    define the primitive type.  Hence, no changes to the SMI or the SNMP
  190.    are necessary to accommodate these textual conventions which are
  191.    adopted merely for the convenience of readers and writers in pursuit
  192.    of the elusive goal of clear, concise, and unambiguous MIB documents.
  193.  
  194.    This MIB introduces the data type of:
  195.  
  196.                        X121Address
  197.  
  198. 3.3.  Structure of MIB
  199.  
  200.    Instances of the objects defined below represent attributes of an
  201.    X.25 Packet Layer interface.  At present these interfaces are
  202.    identified by an ifType object in the Internet-standard MIB-II [5]
  203.    of:
  204.  
  205.                  ddn-x25(4), and
  206.                  rfc887-x25(5).
  207.  
  208.    For these interfaces, the value of the ifSpecific variable in the
  209.    MIB-II [5] has the OBJECT IDENTIFIER value:
  210.  
  211.                  x25    OBJECT IDENTIFIER ::= { transmission 5 }
  212.  
  213.    The objects defined below are similar to those defined in a draft ISO
  214.    document for X.25 management [11]. Some object definitions also
  215.    reference the ISO specification for X.25 [10] to specify  the section
  216.    that will give the reader additional information about the object.
  217.    Access to those documents maybe useful (but isn't essential) to
  218.    understand the names and semantics of some objects.  The similarity
  219.    of these objects with the ISO objects minimizes the instrumentation
  220.    required by those systems that support both OSI and TCP/IP management
  221.    protocols.

  229.  
  230.  
  231.    Since the objects defined here are extensions to the Internet
  232.    Standard MIB [2] and thus also an extension of the second version,
  233.    MIB-II [5], the objects defined here explicitly do not duplicate
  234.    objects defined in existing standards.  In some instances
  235.    clarification of how to apply those objects has been given.
  236.  
  237.    The relationship between an X.25 Packet Layer interface and an
  238.    interface in the context of the Internet-standard MIB [5] is one-to-
  239.    one. As such, the value of an ifIndex object instance can be directly
  240.    used to identify corresponding instances of the objects defined
  241.    below.
  242.  
  243. 3.4.  Tables
  244.  
  245.    The objects below form several tables.  These tables are:
  246.  
  247.                                x25AdmnTable
  248.                                x25OperTable
  249.                                x25StatTable
  250.                                x25ChannelTable
  251.                                x25CircuitTable
  252.                                x25ClearedCircuitTable
  253.                                x25CallParmTable
  254.  
  255.    The x25AdmnTable defines objects for the parameters of an X.25
  256.    interface which the administrator can read and set.  These objects
  257.    are used at interface initialization time to start the interface.
  258.    Once the interface has started, changes to the objects in the
  259.    Administration table may not take affect until the interface is re-
  260.    initialized.
  261.  
  262.    The x25OperTable defines objects that report the current parameters
  263.    used by a running interface.  These objects are read-only.
  264.  
  265.    The x25StatTable defines objects that report operational statistics
  266.    for an X.25 interface.  These are read-only counters of events that
  267.    occurred at the interface.
  268.  
  269.    The x25ChannelTable defines objects to allow the administrator to
  270.    manage the division of channel numbers.
  271.  
  272.    The x25CircuitTable defines objects that return information about
  273.    existing X.25 circuits.  These entries result from calls placed or
  274.    answered by the PLE or from PVCs.
  275.  
  276.    The x25ClearedCircuitTable contains objects for recording the
  277.    termination information from circuits that cleared abnormally.

  285.  
  286.  
  287.    The x25CallParmTable defines the call parameters used to call other
  288.    systems.  This table contains call parameter entries which are
  289.    referenced by other tables.  For example, the x25AdmnTable has one
  290.    object that identifies the entry in the table for the default PLE
  291.    parameters.  The x25CircuitTable has one object that identifies the
  292.    entry in the x25CallParmTable for the parameters in use by that
  293.    circuit.  Other MIBs may also reference entries to identify call
  294.    parameters to use to make X.25 calls.
  295.  
  296. 3.5.  Table Usage
  297.  
  298.    Different tables provide different functions.  The administrator sets
  299.    the starting X.25 parameters in the x25AdmnTable for the X.25 PLE;
  300.    these objects include a reference to the x25CallParmTable entry to
  301.    identify the default call parameters for the PLE.  Once all the
  302.    parameters are set, the administrator initializes the interface.  As
  303.    part of initializing the interface, the operating parameters are
  304.    copied into the interface from the x25AdmnTable; these parameters are
  305.    viewable by getting the objects in the x25OperTable.  (The interface
  306.    maybe started by setting the value of ifAdminStatus to up.)  If any
  307.    PVCs are configured, their parameters can be set in the the
  308.    x25CircuitTable before initializing the interface; this should be
  309.    done in conjunction with configuring higher layer entities to use the
  310.    PVCs via the MIBs for those entities.
  311.  
  312.    Once the PLE completes initialization, it makes additional entries in
  313.    the x25circuitTable for calls placed or answered.  When a circuit is
  314.    cleared, the status of the entry for the circuit is set to closed
  315.    and, if the clear is abnormal, an entry will also be made in the
  316.    x25ClearedCircuitTable.  An entry in the x25CircuitTable with a
  317.    status of closed maybe deleted by the agent at its convenience.  A
  318.    closed entry will always be reused at the time the PLE re-allocates
  319.    the channel number of the entry for another call.  The call
  320.    parameters used for a circuit can be found by looking in the
  321.    x25CircuitTable and following the x25CircuitCallParamId pointer to
  322.    the entry in the x25CallParmTable that contains the parameters.
  323.  
  324.    There are no mechanisms in the X.25 MIB for telling the PLE to place
  325.    an X.25 call. Such mechanisms belong in the MIBs for the higher layer
  326.    entities that use the X.25 circuits.
  327.  
  328. 3.6.  Conformance
  329.

  3484.           made the following changes:
  3485.  
  3486.                A value of dxe was defined for x25AdmnInterfaceMode and
  3487.                x25OperInterfaceMode.
  3488.  
  3489.                The objects in the x25ChannelTable can now have a value
  3490.                of zero to indicate no channels configured in the range.
  3491.  
  3492.                The length of an X121Address was extended to 17 to
  3493.                accommodate the 1988 CCITT X.25 standard.
  3494.  
  3495.                Some object descriptions have been expanded and
  3496.                simplified, these include:  all the channel table objects
  3497.                except the index, x25AdmnDataRxmtCount,
  3498.                x25AdmnRejectCount, x25AdmnRegistrationRequestCount,

  3535.                All reference comments were changed to reference fields.
  3536.  
  3537.                The type PositiveInteger was imported from the RFC1381-
  3538.                MIB and used for all index and timer values.
  3539.  
  3540.                The x25PleTable was split into the x25AdmnTable,
  3541.                x25OperTable, and x25StatTable.
  3542.  
  3543.                The timer and counter objects from the x25CircuitTable
  3544.                were moved to the x25AdmnTable and replicated in the
  3545.                x25OperTable
  3546.  
  3547.                The objects in the x25CircuitTable were reordered to put
  3548.                the non-integer objects at the end of the table for
  3549.                easier implementation.
  3550.  
  3551.                The called and calling extension character set was
  3552.                extended to include a-f, and A-F.
  3553.  
  3554.                Additional states were added to the x25CircuitStatus

  3604.  
  3605.                Many of the tables were combined.  For example, the
  3606.                x25InfoTable, x25PktStatTable, and x25TmrStatTable were
  3607.                combined into the x25PleTable.  The x25ConInfoTable,
  3608.                x25ConStatTable, and x25ConTimrTable were combined into
  3609.                the x25CircuitTable.
  3610.  
  3611.                The objects for call parameters were drastically
  3612.                reworked.  All call parameters were combined in the
  3613.                x25CallParmTable.  Any table, such as the  x25PleTable or
  3614.                x25CircuitTable, that needs to reference call parameters
  3615.                identifies an entry in the new table.  As part of this
  3616.                the x25ConDefTable was deleted and replaced with the
  3617.                x25PleDefCallParamId.
  3618.  
  3619.                The x25PvcTable was deleted; the x25CircuitStatus object

  3621.  
  3622.                The x25ClearedCircuitTable was added to record the status
  3623.                code of cleared circuits.
  3624.  
  3625.                Many object definitions were restructured. For example,
  3626.                the time units for timers was changed from 1/100ths of a
  3627.                second to milliseconds.  Some indexes into tables were
  3628.                replaced with object identifiers.
  3629.  
  3630.                Much of the introductory text was changed and the
  3631.                references were changed to match.

  3646.  
  3647.                the pvcResetting(5) value was changed to pvcResetting(6)
  3648.                to avoid a conflict with a previous use of the number 5.
  3649.  
  3650.                The name of the counter object
  3651.                x25TmrStatRetryCountsExceeded was changed to
  3652.                x25TmrStatRetryCountExceededs.
  3653.  
  3654.                The name of the counter object
  3655.                x25TmrStatClearCountsExceeded was changed to
  3656.                x25TmrStatClearCountExceededs.
  3657.  
  3658.                All occurrence of Guage was changed to Gauge.
