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:
RFC1155 which defines the SMI, the mechanisms used for describing
and naming objects for the purpose of management. RFC1212
defines a more concise description mechanism, which is wholly
consistent with the SMI.
RFC1156 which defines MIB-I, the core set of managed objects for
the Internet suite of protocols. RFC1213, defines MIB-II, an
evolution of MIB-I based on implementation eXPerience and new
operational requirements.
RFC1157 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.
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 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,

"An entry of zone information for a particular
zone and network combination."
INDEX { zipZoneNetStart, zipZoneIndex }
::= { zipTable 1 }
ZipEntry ::= SEQUENCE {
zipZoneName OCTET STRING,
zipZoneIndex INTEGER,
zipZoneNetStart OCTET STRING (SIZE(2)),
zipZoneNetEnd OCTET STRING (SIZE(2)),
zipZoneState INTEGER
}
zipZoneName OBJECT-TYPE
SYNTAX OCTET STRING
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The ASCII zone name of this entry."
::= { zipEntry 1 }
zipZoneIndex OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"An integer that is unique to the zipZoneName
that is present in this entry. For any given
zone name, every zipEntry that has an equal zone
name will have the same zipZoneIndex."
::= { zipEntry 2 }
zipZoneNetStart OBJECT-TYPE
SYNTAX OCTET STRING (SIZE(2))
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The network that starts the range for this
entry. This address is a two octet DDP network
address in network byte order."
::= { zipEntry 3 }
zipZoneNetEnd OBJECT-TYPE
SYNTAX OCTET STRING (SIZE(2))
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The network that ends the range for this
entry. This address is a two octet DDP network
address in network byte order. If the network
to which this zip entry pertains is a Phase 1
network or a non-extended network, the value for
zipZoneNetEnd shall be two bytes of zero."
::= { zipEntry 4 }
zipZoneState OBJECT-TYPE
SYNTAX INTEGER {
valid(1),
invalid(2)
}
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The state of this zip entry.
Setting this object to the value invalid(2) has
the effect of invalidating the corresponding
entry in the zipTable. 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 of the
relevant zipZoneState object."
::= { zipEntry 5 }
-- The NBP Group
nbpTable OBJECT-TYPE
SYNTAX SEQUENCE OF NbpEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"The table of NBP services registered on this
entity."

SYNTAX NbpEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"The description of an NBP service registered on
this entity."

nbpObject OCTET STRING,
nbpType OCTET STRING,
nbpZone OCTET STRING,
nbpState INTEGER
}
nbpIndex OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The index of this NBP entry. This value ranges
from 1 to the number of NBP entries currently
registered on this entity."
::= { nbpEntry 1 }
nbpObject OBJECT-TYPE
SYNTAX OCTET STRING
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The name of the service described by this
entity."
::= { nbpEntry 2 }
nbpType OBJECT-TYPE
SYNTAX OCTET STRING
ACCESS read-write

DESCRIPTION
"The type of the service described by this
entity."
::= { nbpEntry 3 }

DESCRIPTION
"The zone the service described by this entity is
registered in."
::= { nbpEntry 4 }
nbpState OBJECT-TYPE
SYNTAX INTEGER {
valid(1),
invalid(2)
}
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The state of this NBP entry.
Setting this object to the value invalid(2) 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
