               AppleTalk Management Information Base II

Status of this Memo

  This document specifies an Internet standards track protocol for the
  Internet community, and requests discussion and suggestions for
  improvements.  Please refer to the current edition of the "Internet
  Official Protocol Standards" (STD 1) for the standardization state
  and status of this protocol.  Distribution of this memo is unlimited.

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.

  RFC 1243 defines a set of MIB objects for managing the lower layers
  of the AppleTalk protocol stack, up to the Network layer.  This memo
  defines additional objects that exist in the AppleTalk portion of the
  MIB.  These objects provide for the management of the transport and
  session layers of the AppleTalk protocol stack, as well as extensions
  to the lower layers.  This is achieved in an upwardly-compatable
  fashion.

1. The Network Management Framework

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

     STD 16/RFC 1155 which defines the SMI, the mechanisms used for
        describing and naming objects for the purpose of management.

     STD 16/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.  STD 17/RFC 1213 defines MIB-
        II, an evolution of MIB-I based on implementation experience
        and new operational requirements.

     STD 15/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.

RFC 1742                    AppleTalk MIB II                January 1995


  These llap variables were duplicated in the interfaces table of MIB-
  II.

2.4.  Changes

  The IMPORTS list has been updated to reflect the current SNMP
  documents.

  New textual conventions have been defined.

  Hyphens have been removed from enumeration strings.

  Variables used as INDEXes to new tables have ACCESS not-accessible.
  This is because the values of the INDEX variables are contained in
  the object identifier for any of the other variables in the table;
  therefore, it does not need to be explicitly available as data.

  The atportNetConfig and atportZoneConfig variables have been changed
  from read-only to read-write.

  The atportZone variable has be renamed to atportZoneDefault, and its
  DESCRIPTION clause has been clarified.

  The atportType, atportStatus, and kipType variables have had more
  values added to their enumeration lists.

  The DDP group has been split into two groups; one includes variables
  that any AppleTalk node would implement and the other includes
  variables only a router would implement.

  The rtmpState variable now includes another enumeration, invalid(5),
  which is used when deleting rows.

  The variables rtmpRangeStart, rtmpRangeEnd, rtmpNextHop, rtmpType,
  rtmpPort, and rtmpHops have been changed from read-write to read-
  only.

  The ZIP Group has been renamed the ZIP End Node Group.

  The DESCRIPTION clause for zipZoneIndex has been clarified.

  The variables zipZoneName, zipZoneNetStart, and zipZoneNetEnd have
  been changed from read-write to read-only.

  The nbpIndex variable has been changed from read-only to read-write.

  The nbpObject, nbpType, and nbpZone variables now suggest that the
  agent reregister its service when any of these variables is changed.

RFC 1742                    AppleTalk MIB II                January 1995


  The nbpState variable includes new enumerations.

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.

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].

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.






Waldbusser & Frisa                                              [Page 6]

RFC 1742                    AppleTalk MIB II                January 1995


4.1.  Structure of MIB

  The objects are arranged into the following groups:

                 - LLAP
                 - AARP
                 - ATPort
                 - DDP
                 - DDP Router
                 - RTMP
                 - RTMP Stub
                 - KIP
                 - ZIP Router
                 - ZIP End Node
                 - NBP
                 - ATEcho
                 - ATP
                 - PAP
                 - ASP
                 - ADSP
                 - ATPortPtoP
                 - Per Port Counters

  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 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.

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.






Waldbusser & Frisa                                              [Page 7]

RFC 1742                    AppleTalk MIB II                January 1995


4.4.  The AppleTalk Port Group

  An AppleTalk Port is a logical connection to a network over which
  AppleTalk packets can be transmitted.  The "network" could be a
  tunnel, backbone network, point-to-point link, etc, as well as a
  native AppleTalk network.  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.

  The DDP group contains statistical counters for the DDP protocol, and
  a table describing the DDP sockets that have protocol handlers
  registered.

4.6.  The Datagram Delivery Protocol Router Group

  Some variables relevant to the Datagram Delivery Protocol (DDP) are
  only applicable to AppleTalk routers.  These variables are included
  in this group.

4.7.  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.

4.8.  The Routing Table Maintenance Protocol Stub Group

  The RTMP Stub process is implemented by end nodes in order to
  maintain information about the routers on their networks.  The
  variables in this group apply to both routers and end nodes.  This
  group manages the RTMP stub process.

4.9.  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.

RFC 1742                    AppleTalk MIB II                January 1995


4.10.  The Zone Information Protocol Router 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.  Some variables relevant to
  the Zone Information Protocol (ZIP) are only applicable to AppleTalk
  routers.  These variables are included in this group.

4.11.  The Zone Information Protocol End Node Group

  The ZIP End Node group manages the variables relevant to the Zone
  Information Protocol (ZIP) that are applicable to both routers and
  end nodes.

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

4.13.  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.

4.14.  The AppleTalk Transaction Protocol Group

  The AppleTalk Transaction Protocol (ATP) is a transport-level
  protocol that is defined to support transaction based communications.
  The ATP group manages this protocol.

4.15.  The Printer Access Protocol Group

  The Printer Access Protocol (PAP) is a session-level protocol that
  enables communications between workstations and print servers.  The
  PAP group manages this protocol.

4.16.  The AppleTalk Session Protocol Group

  The AppleTalk Session Protocol (ASP) is a session-level protocol that
  enables sequences of communications to occur.  ASP uses the services
  of the AppleTalk Transaction Protocol (ATP), but extends these
  services into the session layer.  The ASP group manages this
  protocol.

RFC 1742                    AppleTalk MIB II                January 1995


4.17.  The AppleTalk Data Stream Protocol Group

  The AppleTalk Data Stream Protocol (ADSP) is a session-level protocol
  that provides symmetric, connection-oriented, full-duplex
  communication between two sockets on the AppleTalk internet.  In
  addition, ADSP handles flow-control and reliability.  The ADSP group
  manages this protocol.

4.18.  The AppleTalk Port Point to Point Group

  The AppleTalk Port Point to Point Group manages ports that have one
  or more associated point-to-point connections.

4.19.  The Per Port Counters Group

  The Per Port Counters Group contains a set of counters which are
  deemed useful on a per port basis.

4.20.  Textual Conventions

  New data types are introduced as textual conventions in this MIB
  document.  These textual conventions enhance the readability of the
  specification and can ease comparison with other specifications if
  appropriate.  It should be noted that the introduction of these
  textual conventions 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 these textual conventions which are 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 types are:

                 ATNetworkNumber ::=         -- 2 octets of network
                                             -- number in network
                                             -- byte order
                         OCTET STRING (SIZE (2))

                 DdpNodeAddress ::=          -- 2 octets of net number
                                             -- in network byte order,
