 AppleTalk Management Information Base
Status of this Memo
 This memo defines objects for managing AppleTalk objects for use with
 the SNMP protocol. This memo is a product of the AppleTalk-IP
 Working Group of the Internet Engineering Task Force (IETF). This
 RFC specifies an IAB standards track protocol for the Internet
 community, and requests discussion and suggestions for improvements.
 Please refer to the current edition of the "IAB Official Protocol
 Standards" for the standardization state and status of this protocol.
 Distribution of this memo is unlimited.

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.

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.
AppleTalk-IP Working Group [Page 3]

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))

 Setting this object to the value invalid(3) has
 the effect of invalidating the corresponding

 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
