          Internet Draft         AppleTalk MIB II             April 1993

          2.  Abstract

          This memo defines an experimental 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.

          RFC1243 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.

          This memo does not specify a standard for the Internet
          community.

          Internet Draft         AppleTalk MIB II             April 1993

          3.  Historical Perspective

          As reported in RFC 1052, IAB Recommendations for the
          Development of Internet Network Management Standards [1], a
          two-prong strategy for network management of TCP/IP-based
          internets was undertaken.  In the short-term, the Simple
          Network Management Protocol (SNMP), defined in RFC 1067, was
          to be used to manage nodes in the Internet community.  In the
          long-term, the use of the OSI network management framework was
          to be examined.  Two documents were produced to define the
          management information: RFC 1065, which defined the Structure
          of Management Information (SMI), and RFC 1066, which defined
          the Management Information Base (MIB).  Both of these
          documents were designed so as to be compatible with both the
          SNMP and the OSI network management framework.

          This strategy was quite successful in the short-term:
          Internet-based network management technology was fielded, by
          both the research and commercial communities, within a few
          months.  As a result of this, portions of the Internet
          community became network manageable in a timely fashion.

          As reported in RFC 1109, Report of the Second Ad Hoc Network
          Management Review Group [2], the requirements of the SNMP and
          the OSI network management frameworks were more different than
          anticipated.  As such, the requirement for compatibility
          between the SMI/MIB and both frameworks was suspended.  This
          action permitted the operational network management framework,
          based on the SNMP, to respond to new operational needs in the
          Internet community by producing MIB-II.

          In May of 1990, the core documents were elevated to "Standard
          Protocols" with "Recommended" status.  As such, the Internet-
          standard network management framework consists of: Structure
          and Identification of Management Information for TCP/IP-based
          internets, RFC 1155 [3], which describes how managed objects
          contained in the MIB are defined; Management Information Base
          for Network Management of TCP/IP-based internets, which
          describes the managed objects contained in the MIB, RFC 1156
          [4]; and, the Simple Network Management Protocol, RFC 1157
          [5], which defines the protocol used to manage these objects.

          Consistent with the IAB directive to produce simple, workable
          systems in the short-term, the list of managed objects defined
          in the Internet-standard MIB was derived by taking only those

          Internet Draft         AppleTalk MIB II             April 1993

          elements which are considered essential.  However, the SMI
          defined three extensibility mechanisms: one, the addition of
          new standard objects through the definitions of new versions
          of the MIB; two, the addition of widely-available but non-
          standard objects through the experimental subtree; and three,
          the addition of private objects through the enterprises
          subtree.  Such additional objects can not only be used for
          vendor-specific elements, but also for experimentation as
          required to further the knowledge of which other objects are
          essential.

          This memo defines extensions to the MIB using the second
          method.  It contains definitions of managed objects used for
          experimentation.

          The following variables have been deprecated in this version
          of the MIB:

          Waldbusser, Frisa                                     [Page 6]



          Internet Draft         AppleTalk MIB II             April 1993

                  llapInPkts
                  llapOutPkts
                  llapInNoHandlers
                  llapInErrors

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

          4.4.  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.

          Internet Draft         AppleTalk MIB II             April 1993

          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.

          The nbpState variable includes new enumerations.

          5.  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.

          5.1.  Format of Definitions

          Section 7 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].

          Internet Draft         AppleTalk MIB II             April 1993

          6.  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.

          6.1.  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

          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.

          6.2.  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.

          6.3.  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.

          6.4.  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.

          6.5.  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.

          6.6.  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.

          6.7.  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

          Waldbusser, Frisa                                    [Page 11]



          Internet Draft         AppleTalk MIB II             April 1993

          AppleTalk internet.  The RTMP group manages the RTMP protocol
          as well as the routing tables generated by this protocol.

          6.8.  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.

          6.9.  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.

          6.10.  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.

          6.11.  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.

          6.12.  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.

          6.13.  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.

          6.14.  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.

          6.15.  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.

          6.16.  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.

          6.17.  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.

          6.18.  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.

          6.19.  The Per Port Counters Group

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

          6.20.  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:

                  removes an invalidated entry from the table.
                  Accordingly, management stations must be prepared to
                  receive from agents tabular information corresponding
                  to entries not currently in use.  Proper

                  When the registration for an entry in the nbpTable
                  fails, it is an implementation-specific matter as to
                  how long the entry will remain in the
                  registrationFailed(3) state before moving to the
                  invalid(4) state.  Note that the entry may pass
                  immediately from the registrationFailed state to
                  the invalid state.

                  Setting this object to the value invalid(4) has the
                  effect of invalidating the corresponding entry in the
                  nbpTable.  That is, it  effectively disassociates the
                  mapping identified with said entry.  It is an
                  implementation-specific matter as to whether the agent
                  removes an invalidated entry from the table.
                  Accordingly, management stations must be prepared to
                  receive from agents tabular information corresponding
                  to entries not currently in use.  Proper
                  interpretation of such entries requires examination
