1.  Abstract

  This memo defines a portion of the Management Information Base (MIB)
  for use with network management protocols in TCP/IP-based internets.
  In particular, it defines objects for managing AppleTalk networks.




AppleTalk-IP Working Group                                      [Page 1]

RFC 1243                     AppleTalk MIB                     July 1991


2.  The Network Management Framework

  The Internet-standard Network Management Framework consists of three
  components.  They are:

     RFC 1155 which defines the SMI, the mechanisms used for describing
     and naming objects for the purpose of management.  RFC 1212
     defines a more concise description mechanism, which is wholly
     consistent with the SMI.

     RFC 1156 which defines MIB-I, the core set of managed objects for
     the Internet suite of protocols.  RFC 1213, defines MIB-II, an
     evolution of MIB-I based on implementation experience and new
     operational requirements.

     RFC 1157 which defines the SNMP, the protocol used for network
     access to managed objects.

  The Framework permits new objects to be defined for the purpose of
  experimentation and evaluation.

3.  Objects

  Managed objects are accessed via a virtual information store, termed
  the Management Information Base or MIB.  Objects in the MIB are
  defined using the subset of Abstract Syntax Notation One (ASN.1) [7]
  defined in the SMI.  In particular, each object has a name, a syntax,
  and an encoding.  The name is an object identifier, an
  administratively assigned name, which specifies an object type.  The
  object type together with an object instance serves to uniquely
  identify a specific instantiation of the object.  For human
  convenience, we often use a textual string, termed the OBJECT
  DESCRIPTOR, to also refer to the object type.

  The syntax of an object type defines the abstract data structure
  corresponding to that object type.  The ASN.1 language is used for
  this purpose.  However, the SMI [3] purposely restricts the ASN.1
  constructs which may be used.  These restrictions are explicitly made
  for simplicity.

  The encoding of an object type is simply how that object type is
  represented using the object type's syntax.  Implicitly tied to the
  notion of an object type's syntax and encoding is how the object type
  is represented when being transmitted on the network.

  The SMI specifies the use of the basic encoding rules of ASN.1 [8],
  subject to the additional requirements imposed by the SNMP.

RFC 1243                     AppleTalk MIB                     July 1991


3.1.  Format of Definitions

  Section 5 contains the specification of all object types contained in
  this MIB module.  The object types are defined using the conventions
  defined in the SMI, as amended by the extensions specified in [9,10].

4.  Overview

  AppleTalk is a protocol suite which features an open peer-to-peer
  architecture that runs over a variety of transmission media.
  AppleTalk is defined in [10].  This protocol suite interoperates with
  the IP protocol suite through various encapsulation methods.  As
  large AppleTalk networks are built that coexist with large IP
  networks, a method to manage the AppleTalk networks with SNMP becomes
  necessary.  This MIB defines managed objects to be used for managing
  AppleTalk networks.

4.1.  Structure of MIB

  The objects are arranged into the following groups:

                     - LLAP
                     - AARP
                     - ATPort
                     - DDP
                     - RTMP
                     - KIP
                     - ZIP
                     - NBP
                     - ATEcho

  These groups are the basic unit of conformance. If the semantics of a
  group is applicable to an implementation, then it must implement all
  objects in that group.  For example, a managed agent must implement
  the KIP group if and only if it implements the KIP protocol.

  These groups are defined to provide a means of assigning object
  identifiers, and to provide a method for managed agents to know which
  objects they must implement.

4.2.  The LocalTalk Link Access Protocol Group

  The LocalTalk Link Access Protocol (LLAP) is a medium-speed data-link
  protocol designed for low cost and plug-and-play operation.  The LLAP
  group is designed to manage all interfaces on a managed device that
  use this protocol.

RFC 1243                     AppleTalk MIB                     July 1991


4.3.  The AppleTalk Address Resolution Protocol Group

  The AppleTalk Address Resolution Protocol (AARP) is used to map
  between AppleTalk node addresses, used by the Datagram Delivery
  Protocol, and the addresses of the underlying data link layer.  The
  AARP table allows for management of the Address Mapping Table on the
  managed device.

4.4.  The AppleTalk Port Group

  An AppleTalk Port is a logical connection to a network over which
  AppleTalk packets can be transmitted.  This group allows the
  management of the configuration of these AppleTalk ports.

4.5.  The Datagram Delivery Protocol Group

  The Datagram Delivery Protocol (DDP) is the network-layer protocol
  that is responsible for the socket-to-socket delivery of datagrams
  over the AppleTalk Internet.  This group manages the DDP layer on the
  managed device.

4.6.  The Routing Table Maintenance Protocol Group

  The Routing Table Maintenance Protocol (RTMP) is used by AppleTalk
  routers to create and maintain the routing tables that dictate the
  process of forwarding datagrams on the AppleTalk internet.  The RTMP
  group manages the RTMP protocol as well as the routing tables
  generated by this protocol.

4.7.  The Kinetics Internet Protocol Group

  The Kinetics Internet Protocol (KIP) is a protocol for encapsulating
  and routing AppleTalk datagrams over an IP internet.  This name is
  historical.  The KIP group manages the KIP routing protocol as well
  as the routing tables generated by this protocol.

4.8.  The Zone Information Protocol Group

  The Zone Information Protocol (ZIP) is used to maintain a mapping
  between networks and zone names to facilitate the name lookup process
  performed by the Name Binding Protocol.  The ZIP group manages this
  protocol and the mapping it produces.

4.9.  The Name Binding Protocol Group

  The Name Binding Protocol (NBP) is a transport-level protocol that is
  used to convert human readable service names into the numeric
  AppleTalk network addresses needed for communicating across the



AppleTalk-IP Working Group                                      [Page 4]

RFC 1243                     AppleTalk MIB                     July 1991


  AppleTalk network.  The NBP group manages this protocol and the NBP
  services that exist on the managed device.

4.10.  The AppleTalk Echo Protocol Group

  The AppleTalk Echo Protocol is a transport-level protocol used to
  test and verify the status of the AppleTalk internet.  The AtEcho
  group manages this protocol.

4.11.  Textual Conventions

  A new data type is introduced as a textual convention in this MIB
  document.  This textual convention enhances the readability of the
  specification and can ease comparison with other specifications if
  appropriate.  It should be noted that the introduction of this
  textual convention has no effect on either the syntax or the
  semantics of any managed objects.  The use of this is merely an
  artifact of the explanatory method used.  Objects defined in terms of
  this method are always encoded by means of the rules that define the
  primitive type.  Hence, no changes to the SMI or the SNMP are
  necessary to accommodate this textual convention which is adopted
  merely for the convenience of readers and writers in pursuit of the
  elusive goal of clear, concise, and unambiguous MIB documents.

  The new data type is:

                 DdpAddress ::=          -- 2 octets of net number,
                                         -- 1 octet of node number
                         OCTET STRING (SIZE (3))
