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.

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,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

3.  Overview

   Ethernet networks have evolved over the past 30 years from simple
   LANs to a variety of other applications, including wide-area
   networks.  To address some of these emerging markets, the IEEE
   802.3ah taskforce defined additional clauses in [802.3ah] for the
