The SNMP agent supports Get, Get-next, and Get-Bulk requests on the OAMDot3 MIB. SNMP Set requests is not supported.
The 802.3ah OAM MIB is defined here: https://tools.ietf.org/html/rfc4878 . This MIB defines objects for managing This MIB defines objects for managing Operations, Administration, and Maintenance (OAM) capabilities on Ethernet-like interfaces.

dot3OamAdminState OID: dot3OamEntry.1 SYNTAX: INTEGER MAX-ACCESS: Read Only |
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 dot3OamAdminState always starts in the disabled (2) state until an explicit management action or configuration information retained by the system causes a transition to the enabled (1) state. When enabled (1), Ethernet OAM will attempt to operate over this interface. |
enabled(1), disabled(2) |
Yes |
|
dot3OamAdminState OID: dot3OamEntry.2 SYNTAX: INTEGER MAX-ACCESS: 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 OAsublayer. This value is always disabled (1) if OAM is disabled on this interface via the dot3OamAdminState.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) ortesting(3)).The passiveWait(3) state is returned only by OAM entities in passive mode (dot3OamMode) and reflects the state in which the OAM entity is waiting to see if the peer device is OA capable. The activeSendLocal(4) value is used by active mode devices (dot3OamMode) and reflects the OAM entity actively trying to discover whether the peer has OAM capability but hasnot yet made that determination. The state sendLocalAndRemote(5) reflects that the local OAentity 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 within the state SEND_LOCAL_REMOTE of the Discovery state diagram [802.3ah, Figure 57-5], with the difference beingwhether the local OAM client has actively rejected the peeringor 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 rejectedthe peering or has just not yet decided. This is indicated via the remote flags field in the OAMPDU (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 (dot3OamAdminState is enabled(1)), but the interface is in half-duplex operation. |

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.

If the event represents a threshold crossing event, the two objects dot3OamEventThresholdHi and dot3OamEventThresholdLo form an unsigned 64-bit integer yielding the value that was crossed for the threshold crossing event (for example, 10, when 11 occurrences happened in 5 seconds while the threshold was 10). The two objects are combined as:dot3OamEventLogThreshold = ((2^32) * dot3OamEventLogThresholdHi)+ dot3OamEventLogThresholdLoOtherwise, this value is returned as all F's (2^32 -1) and adds no useful information. | No | |

| dot3OamEventLogValue
OID: dot3OamEventLogEntry .10 SYNTAX:CounterBasedGauge64 MAX-ACCESS: 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 (for example, 11, when 11Occurrences happened in 5 seconds while the threshold was 10).Otherwise, this value is returned as all F's (2^64 - 1) and adds no useful information | Yes. SLX-OS supports only non-threshold events .For such events this MIB objects expects 1's in all bits | |
| dot3OamEventLogRunningTotal
OID: dot3OamEventLogEntry .11 SYNTAX:CounterBasedGauge64 MAX-ACCESS: Read Only |
Each Event Notification TLV contains a running total of the number of times an event has occurred, as well as the number of times an Event Notification for the event has been transmitted. For non-threshold crossing events, the number of events (dot3OamLogRunningTotal) and the number of resultant Event Notifications (dot3OamLogEventTotal) should be identical. For threshold crossing events, since multiple occurrences may be required to cross the threshold, these values are likely different. This value represents the total number of times this event has happened since the last reset (for example, 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). | Yes.
Note: SLX-OS supports only non threshold events |

For non-threshold crossing events, the number of events (dot3OamLogRunningTotal) and the number of resultant Event Notifications (dot3OamLogEventTotal) should be identical. For threshold crossing events, since multiple occurrences may be required to cross the threshold, these values are likely different. This value represents the total number of timesone or more of these occurrences have resulted in an Event Notification (for example, 51 when 3253 symbol errors have occurred since the last reset, which has resulted in 51 symbolerror threshold crossing events since the last reset) | Yes.

A local threshold crossing event is detected by the local entity, while a remote threshold crossing event is detected by the reception of an Ethernet OAM Event Notification OAMPDU that indicates a threshold event. This notification should not be sent more than once perSecond. The OAM entity can be derived from extracting the ifIndex from the variable bindings. The objects in the notification correspond to the values in a row instance in thedot3OamEventLogTable. | No |
