SNMP over Ethernet

Status of This Memo

This memo describes an experimental method by which the Simple

Network Management Protocol (SNMP) as specified in [1] can be used

over Ethernet MAC layer framing [2] instead of the Internet UDP/IP

protocol stack. This specification is useful for LAN based network

elements that support no higher layer protocols beyond the MAC sub-

layer. Distribution of this memo is unlimited.

Overview and Rational

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 local

networks; for example, repeaters and wiring concentrators. They

include both addressability, and programmable intelligence. These

devices are widely used and increasingly important yet, for the most

part, invisible except through proprietary mechanisms.


Almost all Internet capable network elements use the same mechanism

for encapsulation of the Internet protocol stack regardless of

conformity with the physical characteristics of Ethernet or 802.3,

this mechanism is specified in [3] and [4]. This specification

continues that style with the assignment (by XEROX) of 33100

(hexadecimal 814C) to the Ethernet Type field for SNMP. The data

portion of the Ethernet frame would then be a standard SNMP message

as specified in [1].
