This memo defines a convention for encapsulating Simple Network
Management Protocol (SNMP)  packets over the transport mechanism
provided via the Internetwork Packet Exchange (IPX) protocol .
As stated below and in reference , it is strongly advised that for
interoperability, SNMP be implemented over UDP/IP and not directly on
media or other protocols (such as IPX).
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
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) . The socket address space authority is
administered by Novell.
The use of SNMP over the UDP transport  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 .
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 ...
