dot3OamNonThresholdEvent

Table 1. dot3OamNonThresholdEvent properties
Property name	Value
Application name	EFM_OAM
Event ID	2005
Event name	dot3OamNonThresholdEvent
SNMP notification prefix and OID	DOT3-OAM-MIB.dot3OamNotifications.2
Default severity	minor
Source stream	main
Message format string	Port $ifIndex$ raised $dot3OamEventLogLocation$ fault $dot3OamEventLogType$
Cause	A dot3OamNonThresholdEvent notification is sent when a local or remote non-threshold crossing event is detected. A local event is detected by the local entity, while a remote event is detected by the reception of an Ethernet OAM Event Notification OAMPDU that indicates a non-threshold crossing event. This notification should not be sent more than once per second. 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 of the dot3OamEventLogTable. The management entity should periodically check dot3OamEventLogTable to detect any missed events.
Effect	N/A
Recovery	N/A

dot3OamThresholdEvent

Table 2. dot3OamThresholdEvent properties
Property name	Value
Application name	EFM_OAM
Event ID	2004
Event name	dot3OamThresholdEvent
SNMP notification prefix and OID	DOT3-OAM-MIB.dot3OamNotifications.1
Default severity	major
Source stream	main
Message format string	Port $ifIndex$ raised $dot3OamEventLogLocation$ SF fault $dot3OamEventLogType$ - $dot3OamEventLogValue$ errors exceeded the $dot3OamEventLogThresholdLo$ error threshold during the $dot3OamEventLogWindowLo$ decisecond window
Cause	A dot3OamThresholdEvent notification is sent when a local or remote threshold crossing event is detected. 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 per second. 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 the dot3OamEventLogTable. The management entity should periodically check dot3OamEventLogTable to detect any missed events.
Effect	N/A
Recovery	N/A

tmnxDot3OamLoopCleared

Table 3. tmnxDot3OamLoopCleared properties
Property name	Value
Application name	EFM_OAM
Event ID	2003
Event name	tmnxDot3OamLoopCleared
SNMP notification prefix and OID	TIMETRA-DOT3-OAM-MIB.tmnxDot3OamNotifications.3
Default severity	minor
Source stream	main
Message format string	Loop cleared on port $subject$
Cause	The tmnxDot3OamLoopCleared notification is generated if efm-oam is enabled and the protocol stops receiving PDUs with the source MAC address equal to the MAC address of the port it was received on.
Effect	N/A
Recovery	N/A

tmnxDot3OamLoopDetected

Table 4. tmnxDot3OamLoopDetected properties
Property name	Value
Application name	EFM_OAM
Event ID	2002
Event name	tmnxDot3OamLoopDetected
SNMP notification prefix and OID	TIMETRA-DOT3-OAM-MIB.tmnxDot3OamNotifications.2
Default severity	minor
Source stream	main
Message format string	Loop detected on port $subject$
Cause	The tmnxDot3OamLoopDetected notification is generated if efm-oam is enabled and the protocol receives a PDU with the source MAC address equal to the MAC address of the port it was received on. Only the first such PDU will cause the notification to be generated.
Effect	N/A
Recovery	N/A

tmnxDot3OamNonThresholdEventClr

Table 5. tmnxDot3OamNonThresholdEventClr properties
Property name	Value
Application name	EFM_OAM
Event ID	2008
Event name	tmnxDot3OamNonThresholdEventClr
SNMP notification prefix and OID	TIMETRA-DOT3-OAM-MIB.tmnxDot3OamNotifications.6
Default severity	minor
Source stream	main
Message format string	Port $ifIndex$ cleared $dot3OamEventLogLocation$ fault $dot3OamEventLogType$
Cause	The tmnxDot3OamNonThresholdEventClr notification is generated when the local or remote non-threshold crossing event (DOT3-OAM-MIB::dot3OamNonThresholdEvent) is cleared on the port.
Effect	This non-threshold crossing event is no longer a potential cause for the port to restrict user traffic.
Recovery	There is no recovery for this notification.

tmnxDot3OamPeerChanged

Table 6. tmnxDot3OamPeerChanged properties
Property name	Value
Application name	EFM_OAM
Event ID	2001
Event name	tmnxDot3OamPeerChanged
SNMP notification prefix and OID	TIMETRA-DOT3-OAM-MIB.tmnxDot3OamNotifications.1
Default severity	minor
Source stream	main
Message format string	Peer MAC for port $subject$ has changed to $dot3OamPeerMacAddress$
Cause	The tmnxDot3OamPeerChanged notification is generated when the peer information (specifically the Peer MAC address) changes. Note that this notification will only be sent out if the peer information was previously available and the information changed, and not when the peer information is first learned or becomes unavailable.
Effect	N/A
Recovery	N/A

tmnxDot3OamSdThresholdEvent

Table 7. tmnxDot3OamSdThresholdEvent properties
Property name	Value
Application name	EFM_OAM
Event ID	2006
Event name	tmnxDot3OamSdThresholdEvent
SNMP notification prefix and OID	TIMETRA-DOT3-OAM-MIB.tmnxDot3OamNotifications.4
Default severity	minor
Source stream	main
Message format string	Port $ifIndex$ $tmnxDot3OamSdEventLogCleared$ $tmnxDot3OamSdEventLogLocation$ SD fault $tmnxDot3OamSdEventLogType$ - $tmnxDot3OamSdEventLogValue$ errors exceeded the $tmnxDot3OamEventLogSdThresholdLo$ error threshold during the $tmnxDot3OamSdEventLogWindowLo$ $tmnxDot3OamSdEventLogType$ window
Cause	The tmnxDot3OamSdThresholdEvent notification is generated when a local or remote threshold crossing event for signal degradation is detected. A local threshold crossing SD 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 an SD threshold event. This notification should not be sent more than once per second. 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 the tmnxDot3OamSdEventLogTable. The management entity should periodically check tmnxDot3OamSdEventLogTable to detect any missed events.
Effect	N/A
Recovery	N/A

tmnxDot3OamThresholdEventClr

Table 8. tmnxDot3OamThresholdEventClr properties
Property name	Value
Application name	EFM_OAM
Event ID	2007
Event name	tmnxDot3OamThresholdEventClr
SNMP notification prefix and OID	TIMETRA-DOT3-OAM-MIB.tmnxDot3OamNotifications.5
Default severity	minor
Source stream	main
Message format string	Port $ifIndex$ cleared $dot3OamEventLogLocation$ SF fault $dot3OamEventLogType$ - $dot3OamEventLogValue$ errors exceeded the $dot3OamEventLogThresholdLo$ error threshold during the $dot3OamEventLogWindowLo$ $dot3OamEventLogType$ window
Cause	The tmnxDot3OamThresholdEventClr notification is generated when the local or remote signal failure (SF) threshold crossing event is cleared on the port.
Effect	This SF threshold crossing event is no longer a potential cause for the port to restrict user traffic.
Recovery	There is no recovery for this notification.
