    description
      "The MIB module for managing the new Ethernet OAM features
    introduced by the Ethernet in the First Mile task force (IEEE
    802.3ah).  The functionality presented here is based on IEEE
    802.3ah [802.3ah], released in October, 2004.  [802.3ah] was
    prepared as an addendum to the standing version of IEEE 802.3
    [802.3-2002] at the time.  Since then, [802.3ah] has been
    merged into the base IEEE 802.3 specification in [802.3-2005].
    
    In particular, this MIB focuses on the new OAM functions
    introduced in Clause 57 of [802.3ah].  The OAM functionality
    of Clause 57 is controlled by new management attributes
    introduced in Clause 30 of [802.3ah].  The OAM functions are
    not specific to any particular Ethernet physical layer, and
    can be generically applied to any Ethernet interface of
    [802.3-2002].  
    
    An Ethernet OAM protocol data unit is a valid Ethernet frame
    with a destination MAC address equal to the reserved MAC
    address for Slow Protocols (See 43B of [802.3ah]), a
    lengthOrType field equal to the reserved type for Slow
    Protocols, and a Slow Protocols subtype equal to that of the
    subtype reserved for Ethernet OAM.  OAMPDU is used throughout
    this document as an abbreviation for Ethernet OAM protocol
    data unit.  
    
    The following reference is used throughout this MIB module:

              "At initialization and failure conditions, two OAM entities on
            the same full-duplex Ethernet link begin a discovery phase to
            determine what OAM capabilities may be used on that link.  The
            progress of this initialization is controlled by the OAM
            sublayer.  
                       
            This value is always disabled(1) if OAM is disabled on this
            interface via the cdot3OamAdminState.  
            
            If the link has detected a fault and is transmitting OAMPDUs
            with a link fault indication, the value is linkFault(2). Also,
            if the interface is not operational (ifOperStatus is not 
            up(1)), linkFault(2) is returned.  Note that the object 
            ifOperStatus may not be up(1) as a result of link failure or
            administrative action (ifAdminState being down(2) or
            testing(3)).  
                             
            The passiveWait(3) state is returned only by OAM entities in
            passive mode (cdot3OamMode) and reflects the state in which the
            OAM entity is waiting to see if the peer device is OAM
            capable.  The activeSendLocal(4) value is used by active mode
            devices (cdot3OamMode) and reflects the OAM entity actively
            trying to discover whether the peer has OAM capability but has
            not yet made that determination.  
                             
            The state sendLocalAndRemote(5) reflects that the local OAM
            entity has discovered the peer but has not yet accepted or
            rejected the configuration of the peer.  The local device can,
            for whatever reason, decide that the peer device is
            unacceptable and decline OAM peering.  If the local OAM entity
            rejects the peer OAM entity, the state becomes
            oamPeeringLocallyRejected(7).  If the OAM peering is allowed
            by the local device, the state moves to
            sendLocalAndRemoteOk(6).  Note that both the
            sendLocalAndRemote(5) and oamPeeringLocallyRejected(7) states
            fall within the state SEND_LOCAL_REMOTE of the Discovery state
            diagram [802.3ah, Figure 57-5], with the difference being
            whether the local OAM client has actively rejected the peering
            or has just not indicated any decision yet.  Whether a peering
            decision has been made is indicated via the local flags field
            in the OAMPDU (reflected in the aOAMLocalFlagsField of
            30.3.6.1.10).  
            
            If the remote OAM entity rejects the peering, the state
            becomes oamPeeringRemotelyRejected(8).  Note that both the
            sendLocalAndRemoteOk(6) and oamPeeringRemotelyRejected(8)
            states fall within the state SEND_LOCAL_REMOTE_OK of the
            Discovery state diagram [802.3ah, Figure 57-5], with the
            difference being whether the remote OAM client has rejected
            the peering or has just not yet decided.  This is indicated
            via the remote flags field in the OAM PDU (reflected in the
            aOAMRemoteFlagsField of 30.3.6.1.11).  
                             
            When the local OAM entity learns that both it and the remote
            OAM entity have accepted the peering, the state moves to
            operational(9) corresponding to the SEND_ANY state of the
            Discovery state diagram [802.3ah, Figure 57-5].  
            
            Since Ethernet OAM functions are not designed to work
            completely over half-duplex interfaces, the value
            nonOperHalfDuplex(10) is returned whenever Ethernet OAM is
            enabled (cdot3OamAdminState is enabled(1)) but the interface is

            that active mode provides additional capabilities to initiate
            monitoring activities with the remote OAM peer entity, while
            passive mode generally waits for the peer to initiate OAM
            actions with it.  As an example, an active OAM entity can put
