This document defines a convention for encapsulating Simple Network
Management Protocol (SNMP)  packets over the transport mechanism
provided via the Internetwork Packet Exchange (IPX) protocol .
The Simple Network Management Protocol (SNMP) as defined in  is
now used as an integral part of the network management framework for
TCP/IP-based internets. Together with its companion standards, which
define the Structure of Management Information (SMI) [3,4], and the
Management Information Base (MIB) , the SNMP has received
widespread deployment in many operational networks running the
Internet suite of protocols.
The success of SNMP in the TCP/IP environment has led to its
deployment in non TCP/IP-based internets. This specification
describes the mapping of SNMP onto the Internetwork Packet Exchange
(IPX) protocol  used in Novell NetWare environments.
As noted in , the preferred mapping for SNMP is onto UDP . As
such, this specification is intended for use in environments where
UDP transport is not available. No aspect of this specification
should be construed as a suggestion that, in a heterogeneous
transport environment, a managed agent should support more than one
mapping. Conversely, management stations are strongly encouraged to
support mappings of SNMP onto all popular transports.
2. Mapping SNMP onto IPX
Mapping SNMP onto IPX is straight-forward since IPX provides a
datagram service very similar to that provided by IP/UDP.
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.
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
