Description: Manages Ciena LEOS Ethernet OAM link monitoring, fault detection, and remote loopback configuration.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is WWP-LEOS-OAM-MIB?

This is Ciena/WWP's LEOS implementation of the IEEE 802.3ah (Ethernet in the First Mile) Clause 30 OAM functionality, providing link-level Operations, Administration, and Maintenance capability: link monitoring, remote fault indication, and remote loopback control for Ethernet links. It exposes fault/alarm-oriented data (OAM peer discovery state, remote fault flags such as dying-gasp and critical events) and configuration for enabling remote loopback testing, rather than throughput counters. This MIB is squarely a fault/software-status monitoring tool: it lets an operator see whether OAM is active on a link, detect remote faults signaled by the far-end device, and verify loopback test results, direct indicators of physical link health without needing console access to the remote device. It explicitly builds on IEEE 802.3ah OAM Clause 30 (closely related to the IETF DOT3-OAM-MIB) as its standards basis. It is typically deployed on Ethernet access-network links, such as between a carrier's Metro Ethernet switch and a customer demarcation device, for first-mile fault isolation. Engineers can download the WWP-LEOS-OAM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in WWP-LEOS-OAM-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Ciena/World Wide Packets Metro Ethernet switch
Ethernet access/first-mile demarcation device

Monitoring Examples

No sample objects were provided for this module in the source data. In general, an 802.3ah OAM MIB of this kind exposes per-link OAM peer discovery and fault-flag state, which an operator would poll to detect a remote dying-gasp or critical-event indication signaling an imminent or occurred failure at the far end of an access link.

What Can Be Monitored

OAM peer discovery state
remote link fault indication (dying gasp/critical event)
remote loopback configuration/status
OAM enable state per port

OIDs

OID symbolic	OID numeric	Type	Access	Description
I32 wwpLeosMaxOamPduSize	1.3.6.1.4.1.6141.2.60.400.1.2.1.1.4	Integer32	read-only	The largest OAMPDU that the OAM entity supports. OAM entities exchange maximum OAMPDU sizes and negotiate to use the smaller of the two maximum OAMPDU sizes between the peers. This value is determined by the local implementation.
INT wwpLeosOamAdminState	1.3.6.1.4.1.6141.2.60.400.1.2.1.1.1	INTEGER	read-write	This object is used to provision the default administrative OAM mode for this interface. This object represents the desired state of OAM for this interface. The wwpLeosOamAdminState always starts in the disabled(1) state until an explicit management action or configuration information retained by the system causes a transition to the enabled(2) state. Note that the value of this object is ignored when the interface is not operating in full-duplex mode. OAM is not supported on half-duplex links.
wwpLeosOamCompls	1.3.6.1.4.1.6141.2.60.400.1.1.2
wwpLeosOamConf	1.3.6.1.4.1.6141.2.60.400.1.1
U32 wwpLeosOamConfigRevision	1.3.6.1.4.1.6141.2.60.400.1.2.1.1.5	Unsigned32	read-only	The configuration revision of the OAM entity as reflected in the latest OAMPDU sent by the OAM entity. The configuration revision is used by OAM entities to indicate configuration changes have occurred which might require the peer OAM entity to re-evaluate whether the peering is allowed. See local_satisfied in [802.3ah, 57.3.1.2].
INT wwpLeosOamCriticalEventEnable	1.3.6.1.4.1.6141.2.60.400.1.2.6.1.12	INTEGER	read-write	Indicates whether the local device should attempt to indicate a critical event has occurred via the OAMPDU flags field to its peer OAM entity. If the system does not support dying gasp capability, setting this object has no effect, and reading the object should always result in 'disabled(2)'. By default, this object should have the value enabled(1) for Ethernet like interfaces that support OAM. If the OAM layer does not support event notifications (as indicated via the OamFunctionsSupported attribute), this value is ignored.

Event notification OAMPDUs may be sent in duplicate to increase the probability of successfully being received, given the possibility that a frame may be lost in transit. An Event Notification OAMPDU is indicated by a valid frame with (1) destination MAC address equal to that of the reserved MAC address for Slow Protocols (See 43B of [802.3ah]), (2) a lengthOrType field equal to the reserved type for Slow Protocols, (3) a Slow Protocols subtype equal to that of the subtype reserved for OAM, and (4) an OAMPDU code equals the OAM Event code. A duplicate Event Notification OAMPDU is indicated as an Event Notification OAMPDU with a Sequence Number field that is identical to the previously received Event Notification OAMPDU Sequence Number. Discontinuities of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of the ifCounterDiscontinuityTime.

A duplicate Event Notification OAMPDU is indicated as an Event Notification OAMPDU with a Sequence Number field that is identical to the previously transmitted Event Notification OAMPDU Sequence Number. Discontinuities of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of the ifCounterDiscontinuityTime.
INT wwpLeosOamDyingGaspEnable	1.3.6.1.4.1.6141.2.60.400.1.2.6.1.11	INTEGER	read-write	Indicates whether the local device should attempt to indicate a dying gasp fault via the OAMPDU flags field to its peer OAM entity. If the system does not support dying gasp capability, setting this object has no effect, and reading the object should always result in 'disabled(2)'. By default, this object should have the value enabled(1) for Ethernet like interfaces that support OAM. If the OAM layer does not support event notifications (as indicated via the OamFunctionsSupported attribute), this value is ignored.

The default value of the window is the number of minimum size Ethernet frames that can be received over the physical layer in one second. If wwpLeosOamErrFramePeriodThreshold frame errors occur within a window of wwpLeosOamErrFramePeriodWindow frames, an Event Notification OAMPDU should be generated with an Errored Frame Period Event TLV indicating the threshold has been crossed in this window.
INT wwpLeosOamErrFrameSecsEvNotifEnable	1.3.6.1.4.1.6141.2.60.400.1.2.6.1.10	INTEGER	read-write	Indicates whether the occurrence of an Errored Frame Seconds Summary Event should result in an Event Notification OAMPDU generated by the OAM layer.

The default value is one errored frame second. If wwpLeosOamErrFrameSecsSummaryThreshold frame errors occur within a window of wwpLeosOamErrFrameSecsSummaryWindow (in tenths of seconds), an Event Notification OAMPDU should be generated with an Errored Frame Seconds Summary Event TLV indicating the threshold has been crossed in this window.
I32 wwpLeosOamErrFrameSecsSummaryWindow	1.3.6.1.4.1.6141.2.60.400.1.2.6.1.8	Integer32	read-write	The amount of time (in 100ms intervals) over which the threshold is defined.

This table contains the mechanisms to configure the thresholds to generate the standard Ethernet OAM Event. 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.
wwpLeosOamEventLogEntry	1.3.6.1.4.1.6141.2.60.400.1.2.7.1		not-accessible	An entry in the wwpLeosOamEventLogTable.
U32 wwpLeosOamEventLogEventTotal	1.3.6.1.4.1.6141.2.60.400.1.2.7.1.13	Unsigned32	read-only	This value represents the total number of times one or more of these occurrences have resulted in an event (e.g. 51 when 3253 symbol errors have occurred since the last reset, which has resulted in 51 symbol error threshold crossing events since the last reset).

OCT wwpLeosOamEventLogOui	1.3.6.1.4.1.6141.2.60.400.1.2.7.1.4	OCTET STRING	read-only	The OUI of the entity defining the object type. All IEEE 802.3 defined events (as appearing in [802.3ah] except for the Organizationally Unique Event TLVs) use the IEEE 802.3 OUI of 0x0180C2. Organizations defining their own Event Notification TLVs include their OUI in the Event Notification TLV which gets reflected here.
I32 wwpLeosOamEventLogPort	1.3.6.1.4.1.6141.2.60.400.1.2.7.1.1	Integer32	read-only	An Ethernet port on the switch
C64 wwpLeosOamEventLogRunningTotal	1.3.6.1.4.1.6141.2.60.400.1.2.7.1.12	Counter64	read-only	This value represents the total number of times this occurrence has happened since the last reset (e.g. 3253, when 3253 symbol errors have occurred since the last reset, which has resulted in 51 symbol error threshold crossing events since the last reset).
wwpLeosOamEventLogTable	1.3.6.1.4.1.6141.2.60.400.1.2.7		not-accessible	This table records a history of the events that have occurred at the Ethernet OAM level. These events can include locally detected events, which may result in locally generated OAMPDUs, and remotely detected events, which are detected by the OAM peer entity and signaled to the local entity via Ethernet OAM. Ethernet OAM events can be signaled by Event Notification OAMPDUs or by the flags field in any OAMPDU.
U32 wwpLeosOamEventLogThresholdHi	1.3.6.1.4.1.6141.2.60.400.1.2.7.1.9	Unsigned32	read-only	If the event represents a threshold crossing event, the two objects wwpLeosOamEventThresholdHi and wwpLeosOamEventThresholdLo form an unsigned 64-bit integer yielding the value that was crossed for the threshold crossing event (e.g. 10, when 11 occurrences happened in 5 seconds while the threshold was 10). The two objects are combined as: wwpLeosOamEventLogThreshold = ((2^32) * wwpLeosOamEventLogThresholdHi) + wwpLeosOamEventLogThresholdLo Otherwise, this value is returned as all F's (0xFFFFFFFF) and adds no useful information.
U32 wwpLeosOamEventLogThresholdLo	1.3.6.1.4.1.6141.2.60.400.1.2.7.1.10	Unsigned32	read-only	If the event represents a threshold crossing event, the two objects wwpLeosOamEventThresholdHi and wwpLeosOamEventThresholdLo form an unsigned 64-bit integer yielding the value that was crossed for the threshold crossing event (e.g. 10, when 11 occurrences happened in 5 seconds while the threshold was 10). The two objects are combined as: wwpLeosOamEventLogThreshold = ((2^32) * wwpLeosOamEventLogThresholdHi) + wwpLeosOamEventLogThresholdLo Otherwise, this value is returned as all F's (0xFFFFFFFF) and adds no useful information.
TIM wwpLeosOamEventLogTimestamp	1.3.6.1.4.1.6141.2.60.400.1.2.7.1.3	TimeStamp	read-only	The value of sysUpTime at the time of the logged event. For locally generated events, the time of the event can be accurately retrieved from sysUpTime. For remotely generated events, the time of the event is indicated by the reception of the Event Notification OAMPDU indicating the event occurred on the peer. A system may attempt to adjust the timestamp value to more accurately reflect the time of the event at the peer OAM entity by using other information, such as that found in the timestamp found of the Event Notification TLVs, which provides an indication of the relative time between events at the peer entity.
U32 wwpLeosOamEventLogType	1.3.6.1.4.1.6141.2.60.400.1.2.7.1.5	Unsigned32	read-only	The type of event that generated this entry in the event log. When the OUI is the IEEE 802.3 OUI of 0x0180C2, the following event types are defined: erroredSymbolEvent(1), erroredFramePeriodEvent (2), erroredFrameEvent(3), erroredFrameSecondsEvent(4), linkFault(256), dyingGaspEvent(257), criticalLinkEvent(258) The first four are considered threshold crossing events as they are generated when a metric exceeds a given value within a specified window. The other three are not threshold crossing events. When the OUI is not 0x0180C2, then some other organization has defined the event space. If event subtyping is known to the implementation, it may be reflected here. Otherwise, this value should return all F's (0xFFFFFFFF).
C64 wwpLeosOamEventLogValue	1.3.6.1.4.1.6141.2.60.400.1.2.7.1.11	Counter64	read-only	If the event represents a threshold crossing event, this value indicates the value of the parameter within the given window that generated this event (e.g. 11, when 11 occurrences happened in 5 seconds while the threshold was 10). Otherwise, this value is returned as all F's (0xFFFFFFFFFFFFFFFF) and adds no useful information.
U32 wwpLeosOamEventLogWindowHi	1.3.6.1.4.1.6141.2.60.400.1.2.7.1.7	Unsigned32	read-only	If the event represents a threshold crossing event, the two objects wwpLeosOamEventWindowHi and wwpLeosOamEventWindowLo form an unsigned 64-bit integer yielding the window over which the value was measured for the threshold crossing event (e.g. 5, when 11 occurrences happened in 5 seconds while the threshold was 10). The two objects are combined as: wwpLeosOamEventLogWindow = ((2^32) * wwpLeosOamEventLogWindowHi) + wwpLeosOamEventLogWindowLo Otherwise, this value is returned as all F's (0xFFFFFFFF) and adds no useful information.
U32 wwpLeosOamEventLogWindowLo	1.3.6.1.4.1.6141.2.60.400.1.2.7.1.8	Unsigned32	read-only	If the event represents a threshold crossing event, the two objects wwpLeosOamEventWindowHi and wwpLeosOamEventWindowLo form an unsigned 64-bit integer yielding the window over which the value was measured for the threshold crossing event (e.g. 5, when 11 occurrences happened in 5 seconds while the threshold was 10). The two objects are combined as: wwpLeosOamEventLogWindow = ((2^32) * wwpLeosOamEventLogWindowHi) + wwpLeosOamEventLogWindowLo Otherwise, this value is returned as all F's (0xFFFFFFFF) and adds no useful information.
I32 wwpLeosOamEventPort	1.3.6.1.4.1.6141.2.60.400.1.2.6.1.1	Integer32	read-only	An Ethernet port on the switch
C32 wwpLeosOamframesLostDueToOam	1.3.6.1.4.1.6141.2.60.400.1.2.4.1.15	Counter32	read-only	A count of the number of frames that were dropped by the OAM multiplexer. Since the OAM multiplexer has multiple inputs and a single output, there may be cases where frames are dropped due to transmit resource contention. This counter is incremented whenever a frame is dropped by the OAM layer. When this counter is incremented, no other counters in this MIB are incremented. Discontinuities of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of the ifCounterDiscontinuityTime.
BIT wwpLeosOamFunctionsSupported	1.3.6.1.4.1.6141.2.60.400.1.2.1.1.6	Bits	read-only	The OAM functions supported on this Ethernet like interface. OAM consists of separate functional sets beyond the basic discovery process which is always required. These functional groups can be supported independently by any implementation.

NTF wwpLeosOamLinkLostTimerActiveTrap	1.3.6.1.4.1.6141.2.60.400.1.3.0.2			A wwpLeowsOamLinkLostTimerActiveTrap notification is sent whenever a link lost timer becomes active for a port.
NTF wwpLeosOamLinkLostTimerExpiredTrap	1.3.6.1.4.1.6141.2.60.400.1.3.0.3			A wwpLeowsOamLinkLostTimerActiveTrap notification is sent whenever a link lost timer expires for a port.
I32 wwpLeosOamLocalPort	1.3.6.1.4.1.6141.2.60.400.1.2.2.1.9	Integer32	read-only	An Ethernet port on the local switch.
INT wwpLeosOamLoopbackCommand	1.3.6.1.4.1.6141.2.60.400.1.2.3.1.1	INTEGER	read-write	This attribute initiates or terminates remote loopback with an OAM peer. Writing startRemoteLoopback(2) to this attribute cause the local OAM client to send a loopback OAMPDU to the OAM peer with the loopback enable flags set. Writing stopRemoteLoopback(3) to this attribute will cause the local OAM client to send a loopback OAMPDU to the OAM peer with the loopback enable flags cleared. Writing noLoopback to this attribute has no effect. Writes to this attribute are ignored unless the OAM status of this interface is 'operational' (wwpLeosOamOperStatus). The attribute always returns noLoopback on a read. To determine the loopback status, use the attribute wwpLeosOamLoopbackStatus.
C32 wwpLeosOamLoopbackControlRx	1.3.6.1.4.1.6141.2.60.400.1.2.4.1.6	Counter32	read-only	A count of the number of Loopback Control OAMPDUs transmitted on this interface.

Discontinuities of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of the ifCounterDiscontinuityTime.
wwpLeosOamLoopbackEntry	1.3.6.1.4.1.6141.2.60.400.1.2.3.1		not-accessible	An entry in the table, containing information on the loopback status for a single Ethernet like interface. There is an entry in this table for every Ethernet like interface on which supports OAM and loopback function within OAM (as indicated in wwpLeosOamFunctionsSupported).
INT wwpLeosOamLoopbackIgnoreRx	1.3.6.1.4.1.6141.2.60.400.1.2.3.1.3	INTEGER	read-write	Since OAM loopback is a disruptive operation (user traffic does not pass), this attribute provides a mechanism to provide controls over whether received OAM loopback commands are processed or ignored. When the value is ignore(1), received loopback commands are ignored. When the value is process(2), OAM loopback commands are processed. The default value is to ignore loopback commands (ignore(1)). The attribute has no meaning if the local OAM entity does not support the loopback function (as defined in wwpLeosOamFunctionsSupported).
I32 wwpLeosOamLoopbackPort	1.3.6.1.4.1.6141.2.60.400.1.2.3.1.4	Integer32	read-only	An Ethernet port on the switch
INT wwpLeosOamLoopbackStatus	1.3.6.1.4.1.6141.2.60.400.1.2.3.1.2	INTEGER	read-only	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, as well as by the actions of the local OAM client. When 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. The values of this attribute correspond to the following values of the local and remote parser and multiplexer states. value LclPrsr LclMux RmtPrsr RmtMux noLoopback FWD FWD FWD FWD initLoopback DISCARD DISCARD FWD FWD rmtLoopback DISCARD FWD LPBK DISCARD tmtngLoopback DISCARD DISCARD LPBK DISCARD lclLoopback LPBK DISCARD DISCARD FWD unknown * any other combination *
wwpLeosOamLoopbackTable	1.3.6.1.4.1.6141.2.60.400.1.2.3		not-accessible	This table contains methods to control the loopback state of the local link as well as indicating the status of the loopback function. Loopback can be used to place the remote OAM entity in a state where every received frame (except OAMPDUs) are echoed back over the same interface on which they were received. In this state, at the remote entity, 'normal' traffic is disabled as only the looped back frames are transmitted on the interface. Loopback is thus an intrusive operation that prohibits normal data flow and should be used accordingly.
wwpLeosOamMIB	1.3.6.1.4.1.6141.2.60.400.1
wwpLeosOamMibModule	1.3.6.1.4.1.6141.2.60.400			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]. The following reference is used throughout this MIB module: [802.3ah] refers to: IEEE Std 802.3ah-2004: 'Draft amendment to - Information technology - Telecommunications and information exchange between systems - Local and metropolitan are networks - Specific requirements - Part 3: Carrier sense multiple access with collision detection (CSMA/CD) access method and physical layer specifications - Media Access Control Parameters, Physical Layers and Management Parameters for subscriber access networks', October 2004. [802-2001] refers to: 'IEEE Standard for LAN/MAN (Local Area Network/Metropolitan Area Network): Overview and Architecture', IEEE 802, June 2001. Copyright (c) The Internet Society (2005). This version of this MIB module is part of RFC XXXX; See the RFC itself for full legal notices.
INT wwpLeosOamMode	1.3.6.1.4.1.6141.2.60.400.1.2.1.1.3	INTEGER	read-write	This object configures the mode of OAM operation for this Ethernet like interface. OAM on Ethernet interfaces may be in 'active' mode or 'passive' mode. These two modes differ in 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. The default value of wwpLeosOamMode is dependent on the type of system on which this Ethernet like interface resides. The default value should be 'active(1)' unless it is known that this system should take on a subservient role to the other device connected over this interface. Changing this value results in incrementing the configuration revision field of locally generated OAMPDUs (30.3.6.1.12) and potentially re-doing the OAM discovery process if the wwpLeosOamOperStatus was already operational(9).

INT wwpLeosOamOperStatus	1.3.6.1.4.1.6141.2.60.400.1.2.1.1.2	INTEGER	read-only	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 sub layer. This value is always disabled(1) if OAM is disabled on this interface via the wwpLeosOamAdminState. 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 (wwpLeosOamMode) 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 (wwpLeosOamMode) 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].
