tmnxOamPmThrClear

Table 13. tmnxOamPmThrClear properties
Property name	Value
Application name	OAM
Event ID	2301
Event name	tmnxOamPmThrClear
SNMP notification prefix and OID	TIMETRA-OAM-PM-MIB.tmnxOamPmNotifications.2
Default severity	warning
Message format string	OAM-PM TCA cleared for session " $tmnxOamPmCfgSessName$", test type $tmnxOamPmStsBaseTestType$, measurement interval duration $tmnxOamPmStsMeasIntvlDuration$, MI start $tmnxOamPmStsBaseStartTime$ UTC, delay bin type $tmnxOamPmNotifThrDelayBinType$. Threshold type $tmnxOamPmNotifThrType$, direction $tmnxOamPmNotifThrDirection$, bin lower bound (us) $tmnxOamPmNotifThrBinLowerBound$, configured threshold $tmnxOamPmNotifThrCfgClear$, operational value $tmnxOamPmNotifThrOperClear$. TCA type $tmnxOamPmNotifThrStateType$, suspect flag $tmnxOamPmStsBaseSuspect$.
Cause	A tmnxOamPmThrClear trap is sent at the end of an OAM-PM measurement interval when a loss or delay counter meets or falls below its configured Clear threshold. At most one tmnxOamPmThrClear trap is sent per tmnxOamPmThrRaise trap. OAM-PM thresholds are explained in the description clauses of tmnxOamPmCfgThrDelayTable, tmnxOamPmCfgThrLossFwBwAgTable, and tmnxOamPmCfgThrLossFwBwTable. OAM-PM counters are explained in the description clauses of the tmnxOamPmStatsTableObjs tables.
Effect	For an LMM test, the loss of live traffic has met or fallen below a configured threshold. For other test types, the loss or delay of OAM-PM test probes has met or fallen below a configured threshold, indicating a possible improvement in the loss or delay of live traffic.
Recovery	No recovery is required for this trap.

tmnxOamPmThrRaise

Table 14. tmnxOamPmThrRaise properties
Property name	Value
Application name	OAM
Event ID	2300
Event name	tmnxOamPmThrRaise
SNMP notification prefix and OID	TIMETRA-OAM-PM-MIB.tmnxOamPmNotifications.1
Default severity	warning
Message format string	OAM-PM TCA raised for session " $tmnxOamPmCfgSessName$", test type $tmnxOamPmStsBaseTestType$, measurement interval duration $tmnxOamPmStsMeasIntvlDuration$, MI start $tmnxOamPmStsBaseStartTime$ UTC, delay bin type $tmnxOamPmNotifThrDelayBinType$. Threshold type $tmnxOamPmNotifThrType$, direction $tmnxOamPmNotifThrDirection$, bin lower bound (us) $tmnxOamPmNotifThrBinLowerBound$, configured threshold $tmnxOamPmNotifThrCfgRaise$, operational value $tmnxOamPmNotifThrOperRaise$. TCA type $tmnxOamPmNotifThrStateType$, suspect flag $tmnxOamPmStsBaseSuspect$.
Cause	A tmnxOamPmThrRaise trap is sent when an OAM-PM loss or delay counter meets or exceeds its configured Raise threshold. If an Average Frame Loss Ratio (FLR) threshold (i.e. tmnxOamPmCfgThrLossAvgFlrRaise) is met or exceeded, the tmnxOamPmThrRaise trap is sent at the end of the measurement interval. If another type of threshold (e.g. tmnxOamPmCfgThrLossHliRaise) is met or exceeded, the tmnxOamPmThrRaise trap is sent when the problem is detected. The Average FLR threshold is a special case because the measured Average FLR can fluctuate during a measurement interval. At most one tmnxOamPmThrRaise trap is sent per threshold type during one OAM-PM measurement interval. For example, at most one tmnxOamPmThrRaise trap is sent to record an excessive High Loss Indicator (HLI) count in the forward direction seen in a particular 15 minute interval belonging to the SLM test belonging to OAM-PM session 'oamPmSession1'. OAM-PM thresholds are explained in the description clauses of tmnxOamPmCfgThrDelayTable, tmnxOamPmCfgThrLossFwBwAgTable, and tmnxOamPmCfgThrLossFwBwTable. OAM-PM counters are explained in the description clauses of the tmnxOamPmStatsTableObjs tables.
Effect	For an LMM test, the loss of live traffic has met or exceeded a configured threshold. For the other test types, the loss or delay of OAM-PM test probes has met or exceeded a configured threshold, indicating possible excessive loss or excessive delay of live traffic.
Recovery	Fix the cause of the excessive loss or excessive delay.

Default severity	minor
Message format string	TWAMP server control connection to client $tmnxTwampSrvNotifClientAddr$ could not be established because the system limit ( $tmnxTwampSrvConnectionCount$ concurrent connections) has been reached
Cause	The tmnxTwampSrvMaxConnsExceeded notification is generated when a TWAMP control connection could not be established by the TWAMP server because the system-level maximum number of concurrent TWAMP control connections (tmnxTwampSrvMaxConnections) has been reached.
