- 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.
-
- Specification
-
- 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].
