Definitions and Managed Objects for
Operations, Administration, and Maintenance (OAM) Functions on
Ethernet-Like Interfaces
Status of This Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.

Abstract
This document defines objects for managing Operations,
Administration, and Maintenance (OAM) capabilities on Ethernet-like
interfaces conformant to the Ethernet OAM functionality defined in
the Ethernet in the First Mile (EFM) clauses of the Ethernet
standards. The Ethernet OAM functionality is complementary to the
Simple Network Management Protocol (SNMP) in that it is focused on a
small set of link-specific functions for directly connected Ethernet
interfaces. This document defines objects for controlling those link
OAM functions and for providing results and status of the OAM
functions to management entities.

1. Introduction
The IEEE 802.3ah Ethernet in the First Mile (EFM) taskforce added new
management capabilities to Ethernet-like interfaces. These
management capabilities were introduced to provide some basic Ordered
Aggregate (OA) function on Ethernet media. The defined functionality
includes discovery, error signaling, loopback, and link monitoring.
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community
to manage these new Ethernet interface capabilities.
Conventions Used in This Document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
2. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).

Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
