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.
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.

1. The Network Management Framework
The Internet-standard Network Management Framework consists of three
components. They are:
STD 16/RFC1155 which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management.
STD 16/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. STD 17/RFC1213 defines MIB-
II, an evolution of MIB-I based on implementation eXPerience
and new operational requirements.
STD 15/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.
2. Additions and Changes
This MIB includes additions and changes to RFC1243. These changes
are outlined in the following sections.
2.1. New Groups
The following groups are introduced in this MIB:
- DDP Router
- RTMP Stub
- ZIP Router
- ATP
- PAP
- ASP
- ADSP
- ATPortPtoP
- Per Port Counters
2.2. Additional Variables

llapOutPkts
llapInNoHandlers
llapInErrors
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.
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.
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.
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.
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.
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,
-- 1 octet of node number
OCTET STRING (SIZE (3))
DdpSocketAddress ::= -- 2 octets of net number
-- in network byte order,

-- perform a case-insensitive search and a case-sensitive

-- to the name being inconsistent (SNMPv1 should return a
