Abstract

This memo defines a convention for encapsulating Simple Network

Management Protocol (SNMP) [1] packets over the transport mechanism

provided via the Internetwork Packet Exchange (IPX) protocol [2].

Editor's Note

As stated below and in reference [5], it is strongly advised that for

interoperability, SNMP be implemented over UDP/IP and not directly on

media or other protocols (such as IPX).

1. Introduction

The SNMP protocol has been specified as the official network

management protocol of the Internet. Its widespread acceptance and

implementation by developers, both inside and outside the Internet

community, is fostering synergetic growth to a variety of protocols

and platforms.

This memo addresses the use of SNMP over the IPX protocol, which has

become quite widespread principally due to the popularity of Novell

NetWare. Roughly equivalent to UDP in function, IPX provides

connectionless, unacknowledged datagram service over a variety of

physical media and protocols.

Although modifications have been made elsewhere in the NetWare

protocol suite, IPX is identical to the Xerox Internet Datagram

Protocol (IDP) [3]. The socket address space authority is

administered by Novell.

The use of SNMP over the UDP transport [4] is today the common mode

of operation in the Internet. This specification may be appropriate

for some environments in which UDP transport services are not

available. SNMP implementors should be aware that the choice of

underlying transport may have a significant impact on the

interoperability and ubiquity of the management capability in the

Internet. Considerations relevant to choosing a transport for use

with SNMP are described in [5].

2. Specification

SNMP packets will always set the Packet Type field in the IPX header

to 4 (i.e., Packet Exchange Packet).

2.1 Socket Assignments

SNMP protocol entities will receive GetRequest-PDU, GetNextRequest-

PDU, and SetRequest-PDU messages on socket 36879 (Destination Socket

field set to hexadecimal 900F), and Trap-PDU messages on socket 36880

(Destination Socket field set to hexadecimal 9010).

GetResponse-PDU messages will be addressed to the IPX address and

socket from which the corresponding GetRequest-PDU, GetNextRequest-

PDU, or SetRequest-PDU originated.

2.2 Maximum Packet Length

Although SNMP does not require conformant implementations to accept

messages whose length exceed 484 bytes, it is recommended that

imple...
