+        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:

+        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]."

+          "Ethernet OAM includes the ability to generate and receive
+          event notifications to indicate various link problems.  This
+          table contains the mechanisms to configure the thresholds to
+          generate the standard Ethernet OAM events.
+
+          These events are:
+            - Errored Symbol Period Event.  Generated when the number of
+              symbol errors exceeds a threshold within a given window
+              defined by a number of symbols (e.g. 1,000 symbols out of
+              1,000,000 had errors).
+            - Errored Frame Period Event.  Generated when the number of
+              frame errors exceeds a threshold within a given window
+              defined by a number of frames (e.g. 10 frames out of 1000
+              had errors).
+            - Errored Frame Event.  Generated when the number of frame
+              errors exceeds a threshold within a given window defined
+              by a period of time (e.g. 10 frames in 1 second had
+              errors).
+            - Errored Frame Seconds Summary Event.  Generated when the
+              number of errored frame seconds exceeds a threshold within
+              a given time period (e.g. 10 errored frame seconds within
+              the last 100 seconds).  An errored frame second is defined
+              as a 1 second interval which had >0 frame errors.
