        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.

          In particular, this MIB focused on the changes to Clause 30 of
          the draft that are not specific to any physical layer.  These
          changes are primarily reflected in the new OAM features
          developed under this project, that can be applied to any
          Ethernet like interface.  The OAM features are described in
          Clause 57 of [802.3ah].
          This MIB is excerpted from the draft files directly,only changed
          the object name,added the hh3c as prefix.

          The following reference is used throughout this MIB module:

        MAX-ACCESS  read-only
        STATUS      current
        DESCRIPTION
          "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 hh3cDot3OamAdminState.

          If the link has detected a fault and is transmitting OAMPDUs
          with a link fault indication, the value is linkFault(2).

          The passiveWait(3) state is returned only by OAM entities in
          passive mode (hh3cDot3OamMode) and reflects the state in which the
          OAM entity is waiting to see if the peer device is OAM
          capable.  The activeSendLocal(4) is used by active mode
          devices (hh3cDot3OamMode) 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]."

          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
          the remote OAM entity in a loopback state, where a passive OAM
          entity cannot.

          Changing this value results in incrementing the configuration
          revision field of locally generated OAMPDUs (30.3.6.1.12) and

          "The loopback status of the OAM entity.  This status is
          determined by a combination of the local parser and
          multiplexer states, the remote parser and multiplexer states,

          operating in normal mode with no loopback in progress, the
          status reads noLoopback(1).

          If the OAM client has sent an Loopback OAMPDU and is waiting
          for a response, where the local parser and multiplexer states
          are DISCARD (see [802.3ah, 57.2.11.1]), the status is
          'initiatingLoopback'.  In this case, the local OAM entity has
          yet to receive any acknowledgement that the remote OAM entity
          has received its loopback command request.

          If the local OAM client knows that the remote OAM entity is in
          loopback mode (via the remote state information as described
          in [802.3ah, 57.2.11.1, 30.3.6.1.15]), the status is
          remoteLoopback(3).  If the local OAM client is in the process
          of terminating the remote loopback [802.3ah, 57.2.11.3,
          30.3.6.1.14], with its local multiplexer and parser states in
          DISCARD, the status is terminatingLoopback(4).  If the remote
          OAM client has put the local OAM entity in loopback mode as
          indicated by its local parser state, the status is
          localLoopback(5).

          The unknown(6) status indicates the parser and multiplexer
          combination is unexpected.  This status may be returned if the
          OAM loopback is in a transition state but should not persist.
