+
+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.

+
+
+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]

+
+
+   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))
