Abstract

This memo describes the method by which the Simple Network Management Protocol (SNMP) as specified in [1] can be used over AppleTalk protocols [2] instead of the Internet UDP/IP protocol stack. This specification is useful for network elements which have AppleTalk support but lack TCP/IP support. It should be noted that if a network element supports multiple protocol stacks, and UDP is available, it is the preferred network layer to use.

Introduction

This memo describes the method by which the Simple Network Management

Protocol (SNMP) as specified in [1] can be used over AppleTalk

protocols [2] instead of the Internet UDP/IP protocol stack. This

specification is useful for network elements which have AppleTalk

support but lack TCP/IP support. It should be noted that if a

network element supports multiple protocol stacks, and UDP is

available, it is the preferred network layer to use.

SNMP has been successful in managing Internet capable network

elements which support the protocol stack at least through UDP, the

connectionless Internet transport layer protocol. As originally

designed, SNMP is capable of running over any reasonable transport

mechanism (not necessarily a transport protocol) that supports bi-

directional flow and addressability.

Many non-Internet capable network elements are present in networks.

Some of these elements are equipped with the AppleTalk protocols.

One method of using SNMP to manage these elements is to define a

method of transmitting an SNMP message inside an AppleTalk protocol

data unit.

This RFC is the product of the SNMP over a Multi-protocol Internet

Working Group of the Internet Engineering Task Force (IETF).

1. Background

The AppleTalk equivalent of UDP (and IP) is DDP (Datagram Delivery

Protocol). The header field of a DDP datagram includes (at least

conceptually) source and destination network numbers, source and

destination node numbers, and source and destination socket numbers.

Additionally, DDP datagrams include a "protocol type" in the header

field which may be used to further demultiplex packets. The data

portion of a DDP datagram may contain from zero to 586 octets.

AppleTalk's Name Binding Protocol (NBP) is a distributed name-to-

address mapping protocol. NBP names are logically of the form
