The value of tmnxOamPmCfgTwlRflInactTimer specifies the system inactivity timeout for TWAMP-Light reflectors. A TWAMP-Light reflector replies to TWAMP-Test PDUs. When a reflector sees a TWAMP-Test PDU for a new session (i.e. a {source IP address, source UDP port, destination IP address} triple which is not known to the reflector), the reflector allocates a record for the session. The record is used to ensure that reply PDUs sent for the session have consecutive sequence numbers. When a reflector sees tmnxOamPmCfgTwlRflInactTimer seconds pass without receiving a TWAMP-Test PDU for a particular session, an inactivity timeout has occurred, so the record allocated to the session is freed.

tmnxOamPmCfgBinGroupTable contains the configuration information for OAM Performance Monitoring bin groups.

tmnxOamPmCfgBinGroupEntry contains the configuration information for one OAM Performance Monitoring bin group. Bin group 1 is created by the system on a CPM restart. The configuration of bin group 1 is shown in the following table. Object Value -------------------------------- ------------------------------ tmnxOamPmCfgBinGroupId 1 tmnxOamPmCfgBinGroupRowStatus active(1) tmnxOamPmCfgBinGroupAdminStatus enabled(1) tmnxOamPmCfgBinGroupDescription 'OAM PM default bin group (not modifiable)' tmnxOamPmCfgBinGroupFdBinCount 3 tmnxOamPmCfgBinGroupFdrBinCount 2 tmnxOamPmCfgBinGroupIfdvBinCount 2 Bin group 1 cannot be changed or destroyed. The rest of the rows in this table are created or destroyed using tmnxOamPmCfgBinGroupRowStatus. When a row is created, the following objects must be set in the SNMP Set PDU: tmnxOamPmCfgBinGroupRowStatus tmnxOamPmCfgBinGroupFdBinCount tmnxOamPmCfgBinGroupFdrBinCount tmnxOamPmCfgBinGroupIfdvBinCount The value of the following objects cannot be changed after their row is created: tmnxOamPmCfgBinGroupFdBinCount tmnxOamPmCfgBinGroupFdrBinCount tmnxOamPmCfgBinGroupIfdvBinCount A row can be destroyed if its administrative status (tmnxOamPmCfgBinGroupAdminStatus) is disabled, and no OAM Performance Monitoring sessions refer to the bin group.

The value of tmnxOamPmCfgBinGroupRowStatus specifies the status of the configuration row for the specified bin group.

The value of tmnxOamPmCfgBinGroupAdminStatus specifies whether or not the specified bin group is administratively enabled. An attempt to set this object to 'disabled(2)' will be rejected if tests referring to the specified bin group are enabled. An attempt to set this object to 'enabled(1)' will be rejected if one (or more) of the three sets of lower bounds for the specified bin group (as configured using tmnxOamPmCfgBinLowerBound) is not in strictly ascending order. For example, tmnxOamPmCfgBinGroupAdminStatus.255 cannot be set to 'enabled(1)' if the following lower bound values are configured. Object ID Value (in microseconds) ------------------------------------- ----------------------- tmnxOamPmCfgBinLowerBound.255.fd(1).1 5000 tmnxOamPmCfgBinLowerBound.255.fd(1).2 5000 tmnxOamPmCfgBinLowerBound.255.fd(1).3 5002 Setting this object to 'disabled(2)' deletes ALL the OAM-PM statistics for each test belonging to each session which refers to the specified bin group. For example, if session 'Sess1' has a DMM test and an SLM test configured, and 'Sess1' uses bin-group 255, then disabling bin-group 255 will delete all the DMM and SLM statistics for 'Sess1'.

The value of tmnxOamPmCfgBinGroupDescription specifies the descriptive text for the specified bin group.

The value of tmnxOamPmCfgBinGroupFdBinCount specifies the number of Frame Delay bins to be created for the specified bin group. There is no default value for this object. A value must be provided on row creation. See the DESCRIPTION clause for tmnxOamPmCfgBinGroupEntry for more information.

The value of tmnxOamPmCfgBinGroupFdrBinCount specifies the number of Frame Delay Range bins to be created for the specified bin group. There is no default value for this object. A value must be provided on row creation. See the DESCRIPTION clause for tmnxOamPmCfgBinGroupEntry for more information.

tmnxOamPmCfgBinTable contains the configuration information for OAM Performance Monitoring bins.

tmnxOamPmCfgBinEntry contains the configuration information for one OAM Performance Monitoring bin. Rows are created in this table when one (or more) of the following objects is set: tmnxOamPmCfgBinGroupFdBinCount, tmnxOamPmCfgBinGroupFdrBinCount, or tmnxOamPmCfgBinGroupIfdvBinCount. Suppose, for example, that the following values are set for bin group 255. Object Value ------------------------------------ ----- tmnxOamPmCfgBinGroupFdBinCount.255 4 tmnxOamPmCfgBinGroupFdrBinCount.255 3 tmnxOamPmCfgBinGroupIfdvBinCount.255 2 Then, the following rows will be created in this table (where index columns are underlined with '#', column names have been abbreviated by replacing 'tmnxOamPmCfg' with '_', and the _BinLowerBound column shows the default values). _BinGroupId _BinGroupType _BinId _BinLowerBound (microsec) ########### ############# ###### ------------------------- 255 fd(1) 1 5000 255 fd(1) 2 10000 255 fd(1) 3 15000 255 fdr(2) 1 5000 255 fdr(2) 2 10000 255 ifdv(3) 1 5000 Note that tmnxOamPmCfgBinGroupFdBinCount.255 is 4, but there are only three corresponding rows in this table. The fourth bin is bin 0, which has a hard coded lower bound of 0 microseconds. Bin 0 never has a row in this table. The lower bounds for a particular {tmnxOamPmCfgBinGroupId, tmnxOamPmCfgBinType} pair must be strictly ascending. See the tmnxOamPmCfgBinGroupAdminStatus DESCRIPTION clause for more information.

The value of tmnxOamPmCfgBinType specifies the type of the bin to be configured or read.

A lower bound can be changed if the administrative state (i.e. tmnxOamPmCfgBinGroupAdminStatus) for the parent bin group is disabled. Please see additional restrictions on setting lower bounds in the tmnxOamPmCfgBinEntry DESCRIPTION clause. The default lower bound for bin number 1 is 5000 microseconds. The default lower bound for a subsequent bin number is computed using defLowerBound(n) = defLowerBound(n-1) + (5000 microseconds).

tmnxOamPmCfgSessTable contains the configuration information for OAM Performance Monitoring sessions.

tmnxOamPmCfgSessEntry contains the configuration information for one OAM Performance Monitoring session. Rows are created or destroyed by SNMP Set operations on tmnxOamPmCfgSessRowStatus.

After a session is created, tmnxOamPmCfgSessTestFamily cannot be changed.

The value of tmnxOamPmCfgSessType specifies the type (e.g. 'onDemand(2)') of the specified session. When a session is created, tmnxOamPmCfgSessRowStatus and tmnxOamPmCfgSessType can be specified in the same SNMP Set PDU. Or, tmnxOamPmCfgSessType can be left at its default value. After a session is created, tmnxOamPmCfgSessType cannot be changed.

The value of tmnxOamPmCfgSessBinGroupId specifies the bin group to be used by the specified session. Changing the bin group for a session deletes ALL the OAM-PM statistics for the session's tests.

tmnxOamPmCfgSessEthTable contains the Ethernet endpoint configuration information for OAM Performance Monitoring sessions.

tmnxOamPmCfgSessEthEntry contains the Ethernet endpoint configuration information for one OAM Performance Monitoring session. A row is created when a tmnxOamPmCfgSessTable row is created with tmnxOamPmCfgSessTestFamily = 'ethernet(1)'. A row is destroyed when a tmnxOamPmCfgSessTable row with tmnxOamPmCfgSessTestFamily = 'ethernet(1)' is destroyed. An attempt to change a value in a row for a particular session will be rejected if an administratively enabled test (e.g. an SLM test) exists for the session.

The value of tmnxOamPmCfgSessEthSrcMepId specifies the source Ethernet Maintenance association End Point (MEP) identifier to be used by the specified session. Zero indicates a value has not been configured.

The value of tmnxOamPmCfgSessEthSrcMdIndex specifies the source Ethernet Maintenance Domain (MD) index to be used by the specified session. Zero indicates a value has not been configured.

The value of tmnxOamPmCfgSessEthSrcMaIndex specifies the source Ethernet Maintenance Association (MA) index to be used by the specified session. Zero indicates a value has not been configured.

The value of tmnxOamPmCfgSessEthPriority specifies the value to be copied into the priority field when launching a test PDU for the specified session.

The value of tmnxOamPmCfgSessEthDestMacAddr specifies the destination MAC address for the specified session. The all-zeros MAC address indicates a value has not been configured.

tmnxOamPmCfgDelayDmmTable contains the configuration information for OAM Performance Monitoring Delay Measurement Message (DMM) tests.

tmnxOamPmCfgDelayDmmEntry contains the configuration information for one OAM Performance Monitoring Delay Measurement Message (DMM) test. Rows are created or destroyed by SNMP Set operations on tmnxOamPmCfgDelayDmmRowStatus. An attempt to change any value in a row (except tmnxOamPmCfgDelayDmmAdminStatus and tmnxOamPmCfgDelayDmmOnDmndStatus) will be rejected if tmnxOamPmCfgDelayDmmAdminStatus is 'enabled(1)'.

The value of tmnxOamPmCfgDelayDmmRowStatus specifies the status of the configuration row for the specified session's DMM test. An attempt to create a row for a session with tmnxOamPmCfgSessTestFamily other than 'ethernet(1)' will be rejected.

The value of tmnxOamPmCfgDelayDmmAdminStatus specifies whether or not the specified session's DMM test is administratively enabled. If the session type (tmnxOamPmCfgSessType) is 'proactive(1)', setting tmnxOamPmCfgDelayDmmAdminStatus to 'enabled(1)'/'disabled(2)' starts/stops the test. If the session type is 'onDemand(2)', see the DESCRIPTION clause for tmnxOamPmCfgDelayDmmOnDmndStatus for information on starting/stopping the test. An attempt to set this object to 'enabled(1)' will be rejected if the tmnxOamPmCfgSessEthTable row for the specified session has incomplete endpoint information for the test (e.g. if tmnxOamPmCfgSessEthDestMacAddr is the all-zeroes MAC address).

The value of tmnxOamPmCfgDelayDmmOnDmndStatus specifies the status of the on-demand DMM test for the specified session. Values: 'enabled(1)' Set by an SNMP manager to start an on-demand DMM test. The test will start if tmnxOamPmCfgDelayDmmAdminStatus is 'enabled(1)'. 'disabled(2)' Set by an SNMP manager to stop an on-demand DMM test. Set by SROS to indicate an on-demand DMM test has stopped running because the configured period for the test (i.e. tmnxOamPmCfgDelayDmmTestDuration) has ended. Set by SROS for an on-demand DMM test when tmnxOamPmCfgDelayDmmAdminStatus is set to 'disabled(2)'. 'notApplicable(3)' This code point is the only acceptable value for a proactive DMM test. An attempt to set this code point for an on-demand DMM test will be rejected. The default value is 'disabled(2)' for an on-demand DMM test, and 'notApplicable(3)' for a proactive DMM test.

The value of tmnxOamPmCfgDelayDmmTestId specifies the test identifier for the specified session's DMM test. When a DMM test is created, tmnxOamPmCfgDelayDmmRowStatus and tmnxOamPmCfgDelayDmmTestId must be specified in the same SNMP Set PDU. When a Y.1731 DMM PDU is being built, the test identifier is copied into the PDU's Test ID TLV. An attempt to add a duplicate test identifier to this table will be rejected. Test identifier values larger than 2147483647 are reserved for internal use.

The value of tmnxOamPmCfgDelayDmmInterval specifies the elapsed time between transmission of Y.1731 DMM PDUs for the specified session's DMM test.

The value of tmnxOamPmCfgDelayDmmDataTlvSize specifies the amount of padding to be added to each launched Y.1731 DMM PDU for the specified session's DMM test. Zero specifies that a Data TLV should not be added to each launched Y.1731 DMM PDU. A value larger than zero specifies the total size (including the header) of the Data TLV added to each launched Y.1731 DMM PDU.

The value of tmnxOamPmCfgDelayDmmTestDuration specifies the test duration for the specified session's DMM test. Zero specifies a test which runs until it is manually stopped. An attempt to set a non-zero value will be rejected if tmnxOamPmCfgSessType is 'proactive(1)'.

The value of tmnxOamPmCfgDelayDmmRunTimeLeft indicates the run time remaining for the specified session's DMM test. For example, suppose a DMM test has the following configuration: tmnxOamPmCfgSessType tmnxOamPmCfgDelayDmmTestDuration -------------------- -------------------------------- 'onDemand(2)' 1000 (seconds) Then, when the DMM test is started (see tmnxOamPmCfgDelayDmmOnDmndStatus), tmnxOamPmCfgDelayDmmRunTimeLeft is initialized to 1000 seconds. After a minute, tmnxOamPmCfgDelayDmmRunTimeLeft is 940 seconds. If tmnxOamPmCfgSessType is 'proactive(1)', zero is always returned (because a proactive test runs until it is manually stopped). If tmnxOamPmCfgSessType is 'onDemand(2)' and the test is stopped (see tmnxOamPmCfgDelayDmmOnDmndStatus), zero is returned (because the test is not running).

tmnxOamPmCfgLossSlmTable contains the configuration information for OAM Performance Monitoring Synthetic Loss Message (SLM) tests.

tmnxOamPmCfgLossSlmEntry contains the configuration information for one OAM Performance Monitoring Synthetic Loss Message (SLM) test.

An attempt to change any value in a row (except tmnxOamPmCfgLossSlmAdminStatus and tmnxOamPmCfgLossSlmOnDmndStatus) will be rejected if tmnxOamPmCfgLossSlmAdminStatus is 'enabled(1)'. The following objects must all be set together in one SNMP Set PDU: tmnxOamPmCfgLossSlmChliThreshold, tmnxOamPmCfgLossSlmConsecDeltaTs, tmnxOamPmCfgLossSlmInterval, and tmnxOamPmCfgLossSlmTxFrmsPerDelT.

The value of tmnxOamPmCfgLossSlmRowStatus specifies the status of the configuration row for the specified session's SLM test. An attempt to create a row for a session with tmnxOamPmCfgSessTestFamily other than 'ethernet(1)' will be rejected.

The value of tmnxOamPmCfgLossSlmAdminStatus specifies whether or not the specified session's SLM test is administratively enabled. If the session type (tmnxOamPmCfgSessType) is 'proactive(1)', setting tmnxOamPmCfgLossSlmAdminStatus to 'enabled(1)'/'disabled(2)' starts/stops the test. If the session type is 'onDemand(2)', see the DESCRIPTION clause for tmnxOamPmCfgLossSlmOnDmndStatus for information on starting/stopping the test. An attempt to set this object to 'enabled(1)' will be rejected if the tmnxOamPmCfgSessEthTable row for the specified session has incomplete endpoint information for the test (e.g. if tmnxOamPmCfgSessEthDestMacAddr is the all-zeroes MAC address).

The value of tmnxOamPmCfgLossSlmOnDmndStatus specifies the status of the on-demand SLM test for the specified session. Values: 'enabled(1)' Set by an SNMP manager to start an on-demand SLM test. The test will start if tmnxOamPmCfgLossSlmAdminStatus is 'enabled(1)'. 'disabled(2)' Set by an SNMP manager to stop an on-demand SLM test. Set by SROS to indicate an on-demand SLM test has stopped running because the configured period for the test (i.e. tmnxOamPmCfgLossSlmTestDuration) has ended. Set by SROS for an on-demand SLM test when tmnxOamPmCfgLossSlmAdminStatus is set to 'disabled(2)'. 'notApplicable(3)' This code point is the only acceptable value for a proactive SLM test. An attempt to set this code point for an on-demand SLM test will be rejected. The default value is 'disabled(2)' for an on-demand SLM test, and 'notApplicable(3)' for a proactive SLM test.

The value of tmnxOamPmCfgLossSlmTestId specifies the test identifier for the specified session's SLM test. When an SLM test is created, tmnxOamPmCfgLossSlmRowStatus and tmnxOamPmCfgLossSlmTestId must be specified in the same SNMP Set PDU. When a Y.1731 SLM PDU is being built, the test identifier is copied into the PDU's Test ID field. An attempt to add a duplicate test identifier to this table will be rejected. Test identifier values larger than 2147483647 are reserved for internal use.

The value of tmnxOamPmCfgLossSlmInterval specifies the elapsed time between transmission of Y.1731 SLM PDUs for the specified session's SLM test.

The value of tmnxOamPmCfgLossSlmDataTlvSize specifies the amount of padding to be added to each launched Y.1731 SLM PDU for the specified session's SLM test. Zero specifies that a Data TLV should not be added to each launched Y.1731 SLM PDU. A value larger than zero specifies the total size (including the header) of the Data TLV added to each launched Y.1731 SLM PDU.

The value of tmnxOamPmCfgLossSlmTxFrmsPerDelT specifies the number of Y.1731 SLM frames to send in one MEF-35 'delta_t' (also known as 'Small Time Interval') for the specified session's SLM test. Expressed in milliseconds, delta_t = tmnxOamPmCfgLossSlmTxFrmsPerDelT * tmnxOamPmCfgLossSlmInterval.

The value of tmnxOamPmCfgLossSlmConsecDeltaTs specifies the number of consecutive MEF-35 'delta_t's (also known as 'Small Time Intervals') which constitute a MEF-35 'Availability Window' for the specified session's SLM test. The duration of an Availability Window (in milliseconds) is tmnxOamPmCfgLossSlmTxFrmsPerDelT * tmnxOamPmCfgLossSlmInterval * tmnxOamPmCfgLossSlmConsecDeltaTs. An attempt to change the duration of an Availability Window to more than 10,000 milliseconds will be rejected. An attempt to change tmnxOamPmCfgLossSlmConsecDeltaTs to a value less than or equal to tmnxOamPmCfgLossSlmChliThreshold will be rejected.

The value of tmnxOamPmCfgLossSlmChliThreshold specifies the MEF-35 Consecutive High Loss Interval (CHLI) threshold for the specified session's SLM test. An attempt to change tmnxOamPmCfgLossSlmChliThreshold to a value greater than or equal to tmnxOamPmCfgLossSlmConsecDeltaTs will be rejected.

The value of tmnxOamPmCfgLossSlmFlrThreshold specifies the MEF-35 Frame Loss Ratio (FLR) threshold for the specified session's SLM test. The FLR threshold is used to decide if a MEF-35 Small Time Interval (also known as delta_t) is Available or Unavailable.

The value of tmnxOamPmCfgLossSlmTestDuration specifies the test duration for the specified session's SLM test. Zero specifies a test which runs until it is manually stopped. An attempt to set a non-zero value will be rejected if tmnxOamPmCfgSessType is 'proactive(1)'.

The value of tmnxOamPmCfgLossSlmRunTimeLeft indicates the run time remaining for the specified session's SLM test. For example, suppose an SLM test has the following configuration: tmnxOamPmCfgSessType tmnxOamPmCfgLossSlmTestDuration -------------------- -------------------------------- 'onDemand(2)' 1000 (seconds) Then, when the SLM test is started (see tmnxOamPmCfgLossSlmOnDmndStatus), tmnxOamPmCfgLossSlmRunTimeLeft is initialized to 1000 seconds. After a minute, tmnxOamPmCfgLossSlmRunTimeLeft is 940 seconds. If tmnxOamPmCfgSessType is 'proactive(1)', zero is always returned (because a proactive test runs until it is manually stopped). If tmnxOamPmCfgSessType is 'onDemand(2)' and the test is stopped (see tmnxOamPmCfgLossSlmOnDmndStatus), zero is returned (because the test is not running).

tmnxOamPmCfgMeasIntvlTable contains the configuration information for OAM Performance Monitoring measurement intervals.

tmnxOamPmCfgMeasIntvlEntry contains the configuration information for the OAM Performance Monitoring measurement interval associated with the specified session and measurement interval duration. Rows are created or destroyed by SNMP Set operations on tmnxOamPmCfgMeasIntvlRowStatus.

The value of tmnxOamPmCfgMeasIntvlDuration specifies the duration of the measurement interval (e.g. 'mi15Minutes(2)') to be read or configured.

The value of tmnxOamPmCfgMeasIntvlRowStatus specifies the status of the configuration row for the specified session and measurement interval duration.

The value of tmnxOamPmCfgMeasIntvlAccntPolicy specifies the accounting policy for the specified session and measurement interval duration. Zero specifies that the specified session and measurement interval duration has no associated accounting policy.

The value of tmnxOamPmCfgMeasIntvlsStored specifies the maximum number of historical measurement intervals which can be read using SNMP Get operations. For example, suppose tmnxOamPmCfgMeasIntvlsStored is 32 in the row indexed by {'mySess1', 'mi15Minutes(2)'}. Suppose 'mySess1' has a DMM test which has been running for at least 8 hours (i.e. 15 minutes/interval * 32 intervals). Then, the number of SNMP accessible 15 minute intervals for the test is shown in the following table. Test State Number of SNMP Accessible 15 Minute Intervals ---------- ----------------------------------------------------------- running 33 (i.e. 32 historical intervals, and the current interval) stopped 32 (i.e. 32 historical intervals) At the moment when a test is stopped, the current interval becomes the newest historical interval. If that makes the total number of historical intervals larger than tmnxOamPmCfgMeasIntvlsStored, the oldest historical interval is made SNMP inaccessible. In a typical configuration, older statistics are recorded in a local file (see tmnxOamPmCfgMeasIntvlAccntPolicy). Statistics in the file are not SNMP accessible. The range and default of tmnxOamPmCfgMeasIntvlsStored varies with the row's measurement interval duration index value, as follows. tmnxOamPmCfgMeasIntvlDuration Intvls Stored Range Intvls Stored Default ----------------------------- ------------------- --------------------- 'mi5Minutes(5)' 1..96 32 'mi15Minutes(2)' 1..96 32 'mi1Hour(3)' 1..24 8 'mi1Day(4)' 1..1 1 The following limit is enforced per session (where 'S' is the session name): tmnxOamPmCfgMeasIntvlsStored.S.mi5Minutes(5) + tmnxOamPmCfgMeasIntvlsStored.S.mi15Minutes(2) <= 96.

The value of tmnxOamPmCfgMeasIntvlBoundaryTyp specifies whether or not the start of each measurement interval is aligned to the wall clock. Values: clockAligned(1) For example, if the specified tmnxOamPmCfgMeasIntvlDuration is 'mi1Day(4)', the first measurement interval for the test will start at midnight (UTC). See the DESCRIPTION clause for tmnxOamPmCfgMeasIntvlClockOffset for additional information. testRelative(2) The first measurement interval for the test will start when the test starts.

If tmnxOamPmCfgSessIpSrcUdpPort is non-zero, the source UDP port with port number equal to tmnxOamPmCfgSessIpSrcUdpPort is allocated. The read-only object tmnxOamPmStsSessIpSrcUdpPort indicates the allocated UDP port number.

tmnxOamPmCfgTwampLtTable contains the configuration information for OAM Performance Monitoring TWAMP-Light (Two-Way Active Measurement Protocol, Light) tests.

tmnxOamPmCfgTwampLtEntry contains the configuration information for the OAM Performance Monitoring TWAMP-Light test for the specified session. Rows are created or destroyed by SNMP Set operations on tmnxOamPmCfgTwampLtRowStatus. An attempt to change any value in a row (except tmnxOamPmCfgTwampLtAdminStatus and tmnxOamPmCfgTwampLtOnDmndStatus) will be rejected if tmnxOamPmCfgTwampLtAdminStatus is 'enabled(1)'.

The value of tmnxOamPmCfgTwampLtRowStatus specifies the status of the configuration row for the specified session's TWAMP-Light test. An attempt to create a row for a session with tmnxOamPmCfgSessTestFamily other than 'ip(2)' will be rejected.

The value of tmnxOamPmCfgTwampLtAdminStatus specifies whether or not the specified session's TWAMP-Light test is administratively enabled. If the session type (tmnxOamPmCfgSessType) is 'proactive(1)', setting tmnxOamPmCfgTwampLtAdminStatus to 'enabled(1)'/'disabled(2)' starts/stops the test. If the session type is 'onDemand(2)', see the DESCRIPTION clause for tmnxOamPmCfgTwampLtOnDmndStatus for information on starting/stopping the test. An attempt to set this object to 'enabled(1)' will be rejected if the tmnxOamPmCfgSessIpTable row for the specified session has incomplete information for the test (e.g. if tmnxOamPmCfgSessIpSrcAddressType is 'unknown(0)').

The value of tmnxOamPmCfgTwampLtOnDmndStatus specifies the status of the on-demand TWAMP-Light test for the specified session. Values: 'enabled(1)' Set by an SNMP manager to start an on-demand TWAMP-Light test. The test will start if tmnxOamPmCfgTwampLtAdminStatus is 'enabled(1)'. 'disabled(2)' Set by an SNMP manager to stop an on-demand TWAMP-Light test. Set by SROS to indicate an on-demand TWAMP-Light test has stopped running because the configured period for the test (i.e. tmnxOamPmCfgTwampLtTestDuration) has ended. Set by SROS for an on-demand TWAMP-Light test when tmnxOamPmCfgTwampLtAdminStatus is set to 'disabled(2)'. 'notApplicable(3)' This code point is the only acceptable value for a proactive TWAMP-Light test. An attempt to set this code point for an on-demand TWAMP-Light test will be rejected. The default value is 'disabled(2)' for an on-demand TWAMP-Light test, and 'notApplicable(3)' for a proactive TWAMP-Light test.

The value of tmnxOamPmCfgTwampLtTestId specifies the test identifier for the specified session's TWAMP-Light test. When a TWAMP-Light test is created, tmnxOamPmCfgTwampLtRowStatus and tmnxOamPmCfgTwampLtTestId must be specified in the same SNMP Set PDU. An attempt to add a duplicate test identifier to this table will be rejected. Test identifier values larger than 2147483647 are reserved for internal use.

The value of tmnxOamPmCfgTwampLtTestDuration specifies the test duration for the specified session's TWAMP-Light test. Zero specifies a test which runs until it is manually stopped. An attempt to set a non-zero value will be rejected if tmnxOamPmCfgSessType is 'proactive(1)'.

The value of tmnxOamPmCfgTwampLtRunTimeLeft indicates the run time remaining for the specified session's TWAMP-Light test. For example, suppose a TWAMP-Light test has the following configuration: tmnxOamPmCfgSessType tmnxOamPmCfgTwampLtTestDuration -------------------- ------------------------------- 'onDemand(2)' 1000 (seconds) Then, when the TWAMP-Light test is started (see tmnxOamPmCfgTwampLtOnDmndStatus), tmnxOamPmCfgTwampLtRunTimeLeft is initialized to 1000 seconds. After a minute, tmnxOamPmCfgTwampLtRunTimeLeft is 940 seconds. If tmnxOamPmCfgSessType is 'proactive(1)', zero is always returned (because a proactive test runs until it is manually stopped). If tmnxOamPmCfgSessType is 'onDemand(2)' and the test is stopped (see tmnxOamPmCfgTwampLtOnDmndStatus), zero is returned (because the test is not running).

The value of tmnxOamPmCfgTwampLtCollectStats specifies the type(s) of statistics to collect while the TWAMP-Light test is running. Code points: collectDelayStats(1) - collect TWAMP-Light delay statistics (readable using tmnxOamPmStsDelayTwlTable and tmnxOamPmStsDelayTwlBinTable) collectLossStats(2) - collect TWAMP-Light loss statistics (readable using tmnxOamPmStsLossTwlTable) collectDelayAndLossStats(3) - collectDelayStats(1) and collectLossStats(2), simultaneously Enumeration: 'collectDelayAndLossStats': 3, 'collectLossStats': 2, 'collectDelayStats': 1.

The loss parameters used by SROS for TWAMP-Light tests (e.g. tmnxOamPmCfgTwampLtTxFrmsPerDelT) are modelled after the MEF-35 loss parameters defined for Synthetic Loss Measurement (SLM) tests. Hence, the REFERENCE text for this object is a MEF-35 SLM section. Expressed in milliseconds, delta_t = tmnxOamPmCfgTwampLtTxFrmsPerDelT * tmnxOamPmCfgTwampLtInterval.

The value of tmnxOamPmCfgTwampLtConsecDeltaTs specifies the number of consecutive MEF-35 'delta_t's (also known as 'Small Time Intervals') which constitute a MEF-35 'Availability Window' when computing loss statistics for the specified session's TWAMP-Light test. The loss parameters used by SROS for TWAMP-Light tests (e.g. tmnxOamPmCfgTwampLtConsecDeltaTs) are modelled after the MEF-35 loss parameters defined for Synthetic Loss Measurement (SLM) tests. Hence, the REFERENCE text for this object is a MEF-35 SLM section. The duration of an Availability Window (in milliseconds) is tmnxOamPmCfgTwampLtTxFrmsPerDelT * tmnxOamPmCfgTwampLtInterval * tmnxOamPmCfgTwampLtConsecDeltaTs. An attempt to change the duration of an Availability Window to more than 100,000 milliseconds will be rejected.

The value of tmnxOamPmCfgTwampLtChliThreshold specifies the MEF-35 Consecutive High Loss Interval (CHLI) threshold for the specified session's TWAMP-Light test. The loss parameters used by SROS for TWAMP-Light tests (e.g. tmnxOamPmCfgTwampLtChliThreshold) are modelled after the MEF-35 loss parameters defined for Synthetic Loss Measurement (SLM) tests. Hence, the REFERENCE text for this object is a MEF-35 SLM section. An attempt to change tmnxOamPmCfgTwampLtChliThreshold to a value greater than or equal to tmnxOamPmCfgTwampLtConsecDeltaTs will be rejected.

The value of tmnxOamPmCfgTwampLtFlrThreshold specifies the MEF-35 Frame Loss Ratio (FLR) threshold for the specified session's TWAMP-Light test.

tmnxOamPmCfgTwlRflEntry contains the configuration information for the OAM Performance Monitoring TWAMP-Light reflector for the virtual router specified by the given service identifier. Service identifier zero specifies the Base virtual router (i.e. the virtual router with TIMETRA-VRTR-MIB::vRtrName = 'Base'). A service identifier larger than zero must be the service identifier of a VPRN service (i.e. a service with TIMETRA-SERV-MIB::svcType = 'vprn(4)'). Rows are created or destroyed by SNMP Set operations on tmnxOamPmCfgTwlRflRowStatus. A row indexed by a VPRN service identifier is destroyed when the VPRN service is destroyed.

The value of tmnxOamPmCfgTwlRflRowStatus specifies the status of the configuration row for the TWAMP-Light reflector for the virtual router specified by the given service identifier. When a reflector is created, tmnxOamPmCfgTwlRflRowStatus and tmnxOamPmCfgTwlRflListenUdpPort must be specified in the same SNMP Set PDU.

The value of tmnxOamPmCfgTwlRflAdminStatus specifies whether or not the specified TWAMP-Light reflector is administratively enabled. tmnxOamPmCfgTwlRflListenUdpPort cannot be changed while tmnxOamPmCfgTwlRflAdminStatus is 'enabled(1)'.

The value of tmnxOamPmCfgTwlRflListenUdpPort specifies the UDP port on which the specified TWAMP-Light reflector listens for TWAMP PDUs. When a reflector is created, tmnxOamPmCfgTwlRflRowStatus and tmnxOamPmCfgTwlRflListenUdpPort must be specified in the same SNMP Set PDU. tmnxOamPmCfgTwlRflListenUdpPort cannot be changed while tmnxOamPmCfgTwlRflAdminStatus is 'enabled(1)'. The valid range is (64364..64373). For backwards compatibility reasons, the range has not been restricted in the MIB definition.

tmnxOamPmCfgTwlRflPfxTable contains the configuration information for OAM Performance Monitoring TWAMP-Light (Two-Way Active Measurement Protocol, Light) reflector prefixes. The set of prefixes configured for a TWAMP-Light reflector defines a set of valid source addresses for the reflector. When the reflector is validating an incoming TWAMP-Test PDU, the PDU is rejected (and counted) if its source address is invalid.

tmnxOamPmCfgTwlRflPfxEntry contains the configuration information for the OAM Performance Monitoring TWAMP-Light reflector prefix specified by the indices. Rows are created or destroyed by SNMP Set operations on tmnxOamPmCfgTwlRflPfxRowStatus. Rows are destroyed when the corresponding tmnxOamPmCfgTwlRflTable row is destroyed.

The value of tmnxOamPmCfgTwlRflPfxPrefixType specifies the prefix type of tmnxOamPmCfgTwlRflPfxPrefix.

The value of tmnxOamPmCfgTwlRflPfxPrefix (in combination with tmnxOamPmCfgTwlRflPfxPrefixType and tmnxOamPmCfgTwlRflPfxPrefixLen) specifies a valid source prefix for the TWAMP-Light reflector specified by the given service identifier. A TWAMP-Test PDU with an invalid source address (i.e. a source address which matches none of the prefixes configured against the reflector) will be counted and dropped by the reflector. Therefore, if no prefixes are configured against a reflector, the reflector will drop and count all incoming PDUs. Configuring the prefix 0.0.0.0/0 instructs the reflector to accept the source address in each incoming IPv4 TWAMP-Test PDU. Configuring the prefix 0::0/0 instructs the reflector to accept the source address in each incoming IPv6 TWAMP-Test PDU.

The value of tmnxOamPmCfgTwlRflPfxPrefixLen (in combination with tmnxOamPmCfgTwlRflPfxPrefixType and tmnxOamPmCfgTwlRflPfxPrefix) specifies a valid source prefix for the TWAMP-Light reflector specified by the given service identifier.

If the session type (tmnxOamPmCfgSessType) is 'proactive(1)', setting tmnxOamPmCfgLossLmmAdminStatus to 'enabled(1)'/'disabled(2)' starts/stops the test. If the session type is 'onDemand(2)', see the DESCRIPTION clause for tmnxOamPmCfgLossLmmOnDmndStatus for information on starting/stopping the test. An attempt to set this object to 'enabled(1)' will be rejected if the tmnxOamPmCfgSessEthTable row for the specified session has incomplete endpoint information for the test (e.g. if tmnxOamPmCfgSessEthDestMacAddr is the all-zeroes MAC address).

The value of tmnxOamPmCfgLossLmmOnDmndStatus specifies the status of the on-demand LMM test for the specified session. Values: 'enabled(1)' Set by an SNMP manager to start an on-demand LMM test. The test will start if tmnxOamPmCfgLossLmmAdminStatus is 'enabled(1)'. 'disabled(2)' Set by an SNMP manager to stop an on-demand LMM test. Set by SROS to indicate an on-demand LMM test has stopped running because the configured period for the test (i.e. tmnxOamPmCfgLossLmmTestDuration) has ended. Set by SROS for an on-demand LMM test when tmnxOamPmCfgLossLmmAdminStatus is set to 'disabled(2)'. 'notApplicable(3)' This code point is the only acceptable value for a proactive LMM test. An attempt to set this code point for an on-demand LMM test will be rejected. The default value is 'disabled(2)' for an on-demand LMM test, and 'notApplicable(3)' for a proactive LMM test.

The value of tmnxOamPmCfgLossLmmTestId specifies the test identifier for the specified session's LMM test. When an LMM test is created, tmnxOamPmCfgLossLmmRowStatus and tmnxOamPmCfgLossLmmTestId must be specified in the same SNMP Set PDU.

The value of tmnxOamPmCfgLossLmmRunTimeLeft indicates the run time remaining for the specified session's LMM test. For example, suppose an LMM test has the following configuration: tmnxOamPmCfgSessType tmnxOamPmCfgLossLmmTestDuration -------------------- -------------------------------- 'onDemand(2)' 1000 (seconds) Then, when the LMM test is started (see tmnxOamPmCfgLossLmmOnDmndStatus), tmnxOamPmCfgLossLmmRunTimeLeft is initialized to 1000 seconds. After a minute, tmnxOamPmCfgLossLmmRunTimeLeft is 940 seconds. If tmnxOamPmCfgSessType is 'proactive(1)', zero is always returned (because a proactive test runs until it is manually stopped). If tmnxOamPmCfgSessType is 'onDemand(2)' and the test is stopped (see tmnxOamPmCfgLossLmmOnDmndStatus), zero is returned (because the test is not running).

The value of tmnxOamPmCfgLossLmmTxFrmsPerDelT specifies the number of LMM frames to send in one MEF-35 'delta_t' (also known as 'Small Time Interval') when computing availability statistics for the specified session's LMM test. The availability parameters used by SROS for LMM tests (e.g. tmnxOamPmCfgLossLmmTxFrmsPerDelT) are modelled after the MEF-35 availability parameters defined for Synthetic Loss Measurement (SLM) tests. Hence, the REFERENCE text for this object is a MEF-35 SLM section. Expressed in milliseconds, delta_t = tmnxOamPmCfgLossLmmTxFrmsPerDelT * tmnxOamPmCfgLossLmmInterval.

The value of tmnxOamPmCfgLossLmmConsecDeltaTs specifies the number of consecutive MEF-35 'delta_t's (also known as 'Small Time Intervals') which constitute a MEF-35 'Availability Window' when computing availability statistics for the specified session's LMM test. The availability parameters used by SROS for LMM tests (e.g. tmnxOamPmCfgLossLmmConsecDeltaTs) are modelled after the MEF-35 availability parameters defined for Synthetic Loss Measurement (SLM) tests. Hence, the REFERENCE text for this object is a MEF-35 SLM section. The duration of an Availability Window (in milliseconds) is tmnxOamPmCfgLossLmmTxFrmsPerDelT * tmnxOamPmCfgLossLmmInterval * tmnxOamPmCfgLossLmmConsecDeltaTs. An attempt to change the duration of an Availability Window to more than 100,000 milliseconds will be rejected. An attempt to change tmnxOamPmCfgLossLmmConsecDeltaTs to a value less than or equal to tmnxOamPmCfgLossLmmChliThreshold will be rejected.

The value of tmnxOamPmCfgLossLmmChliThreshold specifies the MEF-35 Consecutive High Loss Interval (CHLI) threshold for the specified session's LMM test. The availability parameters used by SROS for LMM tests (e.g. tmnxOamPmCfgLossLmmChliThreshold) are modelled after the MEF-35 availability parameters defined for Synthetic Loss Measurement (SLM) tests. Hence, the REFERENCE text for this object is a MEF-35 SLM section. An attempt to change tmnxOamPmCfgLossLmmChliThreshold to a value greater than or equal to tmnxOamPmCfgLossLmmConsecDeltaTs will be rejected.

The value of tmnxOamPmCfgLossLmmFlrThreshold specifies the MEF-35 Frame Loss Ratio (FLR) threshold for the specified session's LMM test. The FLR threshold is used to decide if a MEF-35 'delta_t' (also known as 'Small Time Interval') is Available or Unavailable. The availability parameters used by SROS for LMM tests (e.g. tmnxOamPmCfgLossLmmFlrThreshold) are modelled after the MEF-35 availability parameters defined for Synthetic Loss Measurement (SLM) tests. Hence, the REFERENCE text for this object is a MEF-35 SLM section.

tmnxOamPmCfgThrLossFwBwEntry contains the configured thresholds for the forward or backward direction of one OAM-PM loss test. For example, a row may contain the configurable thresholds for the forward direction for the SLM test belonging to OAM-PM session OAM_PM_Eth_session_1. SROS creates/destroys two rows (forward and backward) in this table for each OAM-PM loss test created/destroyed. A manager creates a loss test using: tmnxOamPmCfgLossLmmRowStatus, tmnxOamPmCfgLossSlmRowStatus, or tmnxOamPmCfgTwampLtRowStatus.

The value of tmnxOamPmCfgTestType specifies the test type index of the row. The test types supporting loss thresholds are 'slm(2)', 'twampLight(3)', and 'lmm(4)'.

OAM-PM loss TCAs are enabled for the 'mi15minutes(2)' measurement interval of the OAM-PM session OAM_PM_Eth_session_1 (using tmnxOamPmCfgMeasIntvlLossTCAs and tmnxOamPmCfgMeasIntvlTCAs). 2. tmnxOamPmCfgThrLossAvgFlrRaise is set to 5000 (i.e. 5.000%) for the indices {OAM_PM_Eth_session_1, 'slm(2)', 'forward(1)'}. 3. At the end of a 15 minute interval belonging to OAM_PM_Eth_session_1's SLM test, the average FLR (i.e. tmnxOamPmStsLossSlmAvgFlrFwd) is 5000 (i.e. 5.000%) or more. 4. Generating an average FLR Raise TCA is allowed (e.g. the most recent average FLR TCA for the specified indices was a Clear). Then, SROS generates an average FLR Raise TCA (using tmnxOamPmThrRaise) at the end of the 15-minute interval, for the forward direction. Negative one specifies that average FLR thresholding is disabled for the specified indices (i.e. SROS will not generate a Raise TCA, or a Clear TCA). tmnxOamPmCfgThrLossAvgFlrRaise must be greater than tmnxOamPmCfgThrLossAvgFlrClear. Exception: the combination tmnxOamPmCfgThrLossAvgFlrRaise=-1 and tmnxOamPmCfgThrLossAvgFlrClear=-1 is supported. tmnxOamPmCfgThrLossAvgFlrRaise and tmnxOamPmCfgThrLossAvgFlrClear must be set in the same SNMP Set PDU.

The value of tmnxOamPmCfgThrLossAvgFlrClear specifies the clear threshold for the average Frame Loss Ratio (FLR). Depending on the specified indices, tmnxOamPmCfgThrLossAvgFlrClear is the clear threshold for: tmnxOamPmStsLossSlmAvgFlrFwd, tmnxOamPmStsLossSlmAvgFlrBwd, tmnxOamPmStsLossLmmAvgFlrFwd, tmnxOamPmStsLossLmmAvgFlrBwd, tmnxOamPmStsLossTwlAvgFlrFwd, or tmnxOamPmStsLossTwlAvgFlrBwd. For example, suppose: 1. OAM-PM loss TCAs are enabled for the 'mi15minutes(2)' measurement interval of the OAM-PM session OAM_PM_Eth_session_1 (using tmnxOamPmCfgMeasIntvlLossTCAs and tmnxOamPmCfgMeasIntvlTCAs). 2. tmnxOamPmCfgThrLossAvgFlrClear is set to 4000 (i.e. 4.000%) for the indices {OAM_PM_Eth_session_1, 'slm(2)', 'forward(1)'}. 3. A previous 15 minute interval belonging to OAM_PM_Eth_session_1's SLM test generated an average FLR Raise TCA for the forward direction (see tmnxOamPmCfgThrLossAvgFlrRaise). The TCA has not been cleared. 4. The just-closed 15-minute interval has an average forward FLR for the forward direction (i.e. tmnxOamPmStsLossSlmAvgFlrFwd) of 4000 (i.e. 4.000%), or less. Then, SROS generates an average FLR Clear TCA (using tmnxOamPmThrClear) at the end of the 15-minute interval, for the forward direction. If tmnxOamPmCfgThrLossAvgFlrRaise > 0 AND tmnxOamPmCfgThrLossAvgFlrClear >= 0, average FLR Clear TCAs can be generated for the specified indices. In this case, the maximum number of average FLR TCAs that will be generated for the specified indices across (for example) two 15 minute intervals is two: Raise and Clear. If tmnxOamPmCfgThrLossAvgFlrRaise > 0 AND tmnxOamPmCfgThrLossAvgFlrClear = -1, no average FLR Clear TCAs will be generated for the specified indices. In this case, the maximum number of average FLR TCAs that will be generated for the specified indices across (for example) two 15 minute intervals is two: Raise and Raise. tmnxOamPmCfgThrLossAvgFlrRaise must be greater than tmnxOamPmCfgThrLossAvgFlrClear. Exception: the combination tmnxOamPmCfgThrLossAvgFlrRaise=-1 and tmnxOamPmCfgThrLossAvgFlrClear=-1 is supported. tmnxOamPmCfgThrLossAvgFlrClear and tmnxOamPmCfgThrLossAvgFlrClear must be set in the same SNMP Set PDU.

tmnxOamPmCfgThrLossFwBwAgTable contains configured thresholds for OAM Performance Monitoring loss TCAs. The subset of the loss thresholds that are configurable in the forward, backward, and aggregate directions is configured using this table. An aggregate loss threshold applies to the sum of a forward loss counter and a backward loss counter.

tmnxOamPmCfgThrLossFwBwAgEntry contains the configured thresholds for the forward, backward, or aggregate direction of one OAM-PM loss test. For example, a row may contain the configurable thresholds for the forward direction for the SLM test belonging to OAM-PM session OAM_PM_Eth_session_1. SROS creates/destroys three rows (forward, backward, and aggregate) in this table for each OAM-PM LMM, SLM or TWAMP-Light test created/destroyed. A manager creates an LMM, SLM or TWAMP-Light test using: tmnxOamPmCfgLossLmmRowStatus, tmnxOamPmCfgLossSlmRowStatus, or tmnxOamPmCfgTwampLtRowStatus.

The value of tmnxOamPmCfgForwardBackwardAggr specifies the direction index of the row.

The value of tmnxOamPmCfgThrLossChliRaise specifies the raise threshold for Consecutive High Loss Intervals (CHLIs). Depending on the specified indices, tmnxOamPmCfgThrLossChliRaise is the raise threshold for: tmnxOamPmStsLossLmmChliBwd, tmnxOamPmStsLossLmmChliFwd + tmnxOamPmStsLossLmmChliBwd, tmnxOamPmStsLossLmmChliFwd, tmnxOamPmStsLossSlmChliBwd, tmnxOamPmStsLossSlmChliFwd + tmnxOamPmStsLossSlmChliBwd, tmnxOamPmStsLossSlmChliFwd, tmnxOamPmStsLossTwlChliBwd, tmnxOamPmStsLossTwlChliFwd + tmnxOamPmStsLossTwlChliBwd, or tmnxOamPmStsLossTwlChliFwd. For example, suppose: 1. OAM-PM loss TCAs are enabled for the 'mi15minutes(2)' measurement interval of the OAM-PM session OAM_PM_Eth_session_1 (using tmnxOamPmCfgMeasIntvlLossTCAs and tmnxOamPmCfgMeasIntvlTCAs). 2. tmnxOamPmCfgThrLossChliRaise is set to 7 for the indices {OAM_PM_Eth_session_1, 'slm(2)', 'forward(1)'}. 3. A 15 minute interval belonging to OAM_PM_Eth_session_1's SLM test has its forward CHLI count (i.e. tmnxOamPmStsLossSlmChliFwd) increase to 7. 4. Generating a CHLI Raise TCA is allowed (e.g. the most recent CHLI TCA for the specified indices was a Clear). Then, SROS immediately generates a CHLI Raise TCA (using tmnxOamPmThrRaise) for the 15-minute interval, for the forward direction. Negative one specifies that CHLI thresholding is disabled for the specified indices (i.e. SROS will not generate a Raise TCA, or a Clear TCA). tmnxOamPmCfgThrLossChliRaise must be greater than tmnxOamPmCfgThrLossChliClear. Exception: the combination tmnxOamPmCfgThrLossChliRaise=-1 and tmnxOamPmCfgThrLossChliClear=-1 is supported. tmnxOamPmCfgThrLossChliRaise and tmnxOamPmCfgThrLossChliClear must be set in the same SNMP Set PDU. The upper bound of this object is the maximum number of MEF-35 'delta_t' time intervals (also known as 'Small Time Intervals') which can occur in a 24 hour measurement interval.

The value of tmnxOamPmCfgThrLossChliClear specifies the clear threshold for Consecutive High Loss Intervals (CHLIs). tmnxOamPmCfgThrLossChliClear is the clear threshold for the list of counters specified in the tmnxOamPmCfgThrLossChliRaise DESCRIPTION clause. For example, suppose: 1. OAM-PM loss TCAs are enabled for the 'mi15minutes(2)' measurement interval of the OAM-PM session OAM_PM_Eth_session_1 (using tmnxOamPmCfgMeasIntvlLossTCAs and tmnxOamPmCfgMeasIntvlTCAs). 2. tmnxOamPmCfgThrLossChliClear is set to 5 for the indices {OAM_PM_Eth_session_1, 'slm(2)', 'forward(1)'}. 3. A previous 15 minute interval belonging to OAM_PM_Eth_session_1's SLM test generated a CHLI Raise TCA for the forward direction (see tmnxOamPmCfgThrLossChliRaise). The TCA has not been cleared. 4. The just-closed 15-minute interval has an forward CHLI count for the forward direction (i.e. tmnxOamPmStsLossSlmChliFwd) of 5, or less. Then, SROS generates a CHLI Clear TCA (using tmnxOamPmThrClear) for the 15-minute interval, for the forward direction. If tmnxOamPmCfgThrLossChliRaise>0 AND tmnxOamPmCfgThrLossChliClear>=0, CHLI Clear TCAs can be generated for the specified indices. In this case, the maximum number of CHLI TCAs that will be generated for the specified indices across (for example) two 15 minute intervals is two: Raise and Clear. If tmnxOamPmCfgThrLossChliRaise>0 AND tmnxOamPmCfgThrLossChliClear=-1, no CHLI Clear TCAs will be generated for the specified indices. In this case, the maximum number of CHLI TCAs that will be generated for the specified indices across (for example) two 15 minute intervals is two: Raise and Raise. tmnxOamPmCfgThrLossChliRaise must be greater than tmnxOamPmCfgThrLossChliClear. Exception: the combination tmnxOamPmCfgThrLossChliRaise=-1 and tmnxOamPmCfgThrLossChliClear=-1 is supported. tmnxOamPmCfgThrLossChliClear and tmnxOamPmCfgThrLossChliClear must be set in the same SNMP Set PDU.

The value of tmnxOamPmCfgThrLossHliRaise specifies the raise threshold for High Loss Intervals (HLIs). tmnxOamPmCfgThrLossHliRaise has the same operating principles as tmnxOamPmCfgThrLossChliRaise. Depending on the specified indices, tmnxOamPmCfgThrLossHliRaise is the raise threshold for: tmnxOamPmStsLossLmmHliBwd, tmnxOamPmStsLossLmmHliFwd + tmnxOamPmStsLossLmmHliBwd, tmnxOamPmStsLossLmmHliFwd, tmnxOamPmStsLossSlmHliBwd, tmnxOamPmStsLossSlmHliFwd + tmnxOamPmStsLossSlmHliBwd, tmnxOamPmStsLossSlmHliFwd, tmnxOamPmStsLossTwlHliBwd, tmnxOamPmStsLossTwlHliFwd + tmnxOamPmStsLossTwlHliBwd, or tmnxOamPmStsLossTwlHliFwd.

The value of tmnxOamPmCfgThrLossHliClear specifies the clear threshold for High Loss Intervals (HLIs). tmnxOamPmCfgThrLossHliClear has the same operating principles as tmnxOamPmCfgThrLossChliClear. tmnxOamPmCfgThrLossHliClear is the clear threshold for the list of counters specified in the tmnxOamPmCfgThrLossHliRaise DESCRIPTION clause.

The value of tmnxOamPmCfgThrLossUnavlIndRaise specifies the raise threshold for the number of availability indicators evaluated as Unavailable. tmnxOamPmCfgThrLossUnavlIndRaise has the same operating principles as tmnxOamPmCfgThrLossChliRaise. Depending on the specified indices, tmnxOamPmCfgThrLossUnavlIndRaise is the raise threshold for: tmnxOamPmStsLossLmmUnavlIndBwd, tmnxOamPmStsLossLmmUnavlIndFwd + tmnxOamPmStsLossLmmUnavlIndBwd, tmnxOamPmStsLossLmmUnavlIndFwd, tmnxOamPmStsLossSlmUnavlIndBwd, tmnxOamPmStsLossSlmUnavlIndFwd + tmnxOamPmStsLossSlmUnavlIndBwd, tmnxOamPmStsLossSlmUnavlIndFwd, tmnxOamPmStsLossTwlUnavlIndBwd, tmnxOamPmStsLossTwlUnavlIndFwd + tmnxOamPmStsLossTwlUnavlIndBwd, or tmnxOamPmStsLossTwlUnavlIndFwd.

The value of tmnxOamPmCfgThrLossUnavlIndClear specifies the clear threshold for the number of availability indicators evaluated as Unavailable. tmnxOamPmCfgThrLossUnavlIndClear has the same operating principles as tmnxOamPmCfgThrLossChliClear. tmnxOamPmCfgThrLossUnavlIndClear is the clear threshold for the list of counters specified in the tmnxOamPmCfgThrLossUnavlIndRaise DESCRIPTION clause.

The value of tmnxOamPmCfgThrLossUndtAvlRaise specifies the raise threshold for the number of availability indicators evaluated as Available based on extrapolation from the previous state. tmnxOamPmCfgThrLossUndtAvlRaise has the same operating principles as tmnxOamPmCfgThrLossChliRaise. Depending on the specified indices, tmnxOamPmCfgThrLossUndtAvlRaise is the raise threshold for: tmnxOamPmStsLossLmmUndtAvlBwd, tmnxOamPmStsLossLmmUndtAvlFwd + tmnxOamPmStsLossLmmUndtAvlBwd, tmnxOamPmStsLossLmmUndtAvlFwd, tmnxOamPmStsLossSlmUndtAvlBwd, tmnxOamPmStsLossSlmUndtAvlFwd + tmnxOamPmStsLossSlmUndtAvlBwd, tmnxOamPmStsLossSlmUndtAvlFwd, tmnxOamPmStsLossTwlUndtAvlBwd, tmnxOamPmStsLossTwlUndtAvlFwd + tmnxOamPmStsLossTwlUndtAvlBwd, or tmnxOamPmStsLossTwlUndtAvlFwd.

The value of tmnxOamPmCfgThrLossUndtAvlClear specifies the clear threshold for the number of availability indicators evaluated as Available based on extrapolation from the previous state. tmnxOamPmCfgThrLossUndtAvlClear has the same operating principles as tmnxOamPmCfgThrLossChliClear. tmnxOamPmCfgThrLossUndtAvlClear is the clear threshold for the list of counters specified in the tmnxOamPmCfgThrLossUndtAvlRaise DESCRIPTION clause.

The value of tmnxOamPmCfgThrLossUndtUnavlRais specifies the raise threshold for the number of availability indicators evaluated as Unavailable based on extrapolation from the previous state. tmnxOamPmCfgThrLossUndtUnavlRais has the same operating principles as tmnxOamPmCfgThrLossChliRaise.

tmnxOamPmCfgThrDelayTable contains threshold configuration for OAM Performance Monitoring delay TCAs.

tmnxOamPmCfgThrDelayEntry contains the threshold configuration for one OAM-PM bin group, bin type, and direction. For example, a row may contain the threshold configuration for bin group 255, bin type 'ifdv(3)', and direction 'twoWay(3)'. SROS creates/destroys nine rows (i.e. {'fd(1)', 'fdr(2)', 'ifdv(3)'} x {'forward(1)', 'backward(2)', 'twoWay(3)'}) when an OAM-PM bin group is created/destroyed. A manager creates/destroys an OAM-PM bin group using tmnxOamPmCfgBinGroupRowStatus. The objects in this table cannot be changed from the default value when the index value tmnxOamPmCfgBinGroupId is 1.

The value of tmnxOamPmCfgForwardBackward2Way specifies the direction of the row to be configured or read.

The value of tmnxOamPmCfgThrDelayLowestBin specifies the lowest OAM-PM delay bin to be used when applying a configured Raise or Clear delay threshold. The usage is described in the tmnxOamPmCfgThrDelayRaise and tmnxOamPmCfgThrDelayClear DESCRIPTION clauses.

The value of tmnxOamPmCfgThrDelayRaise specifies the OAM-PM raise threshold for excessive delay. For example, suppose: 1. tmnxOamPmCfgThrDelayRaise=1000 and tmnxOamPmCfgThrDelayLowestBin=7 for the index values 255, 'ifdv(3)', 'twoWay(3)'. 2. Bin group 255 has been configured with 10 Inter-Frame Delay Variation (IFDV) bins (numbered 0..9), using tmnxOamPmCfgBinGroupIfdvBinCount. 3. The OAM-PM session 'oamPmSession1' is configured to use bin group 255 (using tmnxOamPmCfgSessBinGroupId). 4. OAM-PM delay TCAs are enabled for the measurement interval with indices 'oamPmSession1', 'mi15Minutes(2)' (using tmnxOamPmCfgMeasIntvlDelayTCAs and tmnxOamPmCfgMeasIntvlTCAs). 5. During a 15 minute interval belonging to a DMM test which belongs to 'oamPmSession1', the following inequality becomes true (where only the last two indices of the object are shown, and the last index is a bin number): tmnxOamPmStsDelayDmmBin2wyCount.ifdv(3).7 + tmnxOamPmStsDelayDmmBin2wyCount.ifdv(3).8 + tmnxOamPmStsDelayDmmBin2wyCount.ifdv(3).9 >= 1000 Then, a delay Raise TCA (using tmnxOamPmThrRaise) will be generated immediately. The TCA suppression and configuration rules for tmnxOamPmCfgThrDelayRaise and tmnxOamPmCfgThrDelayClear are the same as the rules for tmnxOamPmCfgThrLossChliRaise and tmnxOamPmCfgThrLossChliClear. The upper bound of this object is the maximum number of DMM PDUs (or TWAMP-Test PDUs) which can be sent in the longest supported (i.e. 24 hour) measurement interval.

The value of tmnxOamPmCfgThrDelayClear specifies the OAM-PM clear threshold for excessive delay. For example, suppose: 1. tmnxOamPmCfgThrDelayClear=900 and tmnxOamPmCfgThrDelayLowestBin=7 for the index values 255, 'ifdv(3)', 'twoWay(3)'. 2. Bin group 255 has been configured with 10 Inter-Frame Delay Variation (IFDV) bins (numbered 0..9), using tmnxOamPmCfgBinGroupIfdvBinCount. 3. The OAM-PM session 'oamPmSession1' is configured to use bin group 255 (using tmnxOamPmCfgSessBinGroupId). 4. OAM-PM delay TCAs are enabled for the measurement interval with indices 'oamPmSession1', 'mi15Minutes(2)' (using tmnxOamPmCfgMeasIntvlDelayTCAs and tmnxOamPmCfgMeasIntvlTCAs). 5. At the end of a 15 minute interval belonging to a DMM test which belongs to 'oamPmSession1', the following inequality is true (where only the last two indices of the object are shown, and the last index is a bin number): tmnxOamPmStsDelayDmmBin2wyCount.ifdv(3).7 + tmnxOamPmStsDelayDmmBin2wyCount.ifdv(3).8 + tmnxOamPmStsDelayDmmBin2wyCount.ifdv(3).9 <= 900 6. Generating a delay Clear TCA is allowed (i.e. the most recent delay TCA for the specified indices was a Raise). Then, a delay Clear TCA (using tmnxOamPmThrClear) will be generated. The TCA suppression and configuration rules for tmnxOamPmCfgThrDelayRaise and tmnxOamPmCfgThrDelayClear are the same as the rules for tmnxOamPmCfgThrLossChliRaise and tmnxOamPmCfgThrLossChliClear.

The value of tmnxOamPmCfgThrDelayExclBinFrTca specifies the bin number of the lowest delay bin to be excluded from the OAM-PM TCA calculations for the specified bin group, bin type, and direction. Configuring tmnxOamPmCfgThrDelayExclBinFrTca allows outlier high delay frames to be ignored when deciding to raise or clear a delay TCA. For example, suppose the following values are configured for bin group 255. Object Value ---------------------------------------------------- ----- tmnxOamPmCfgBinGroupFdBinCount.255 10 tmnxOamPmCfgThrDelayLowestBin.255.fd(1).forward(1) 6 tmnxOamPmCfgThrDelayExclBinFrTca.255.fd(1).forward(1) 8 Then, the decision to raise or clear a Frame Delay (FD) TCA for the forward direction will be made based on the packet counts in bins 6 and 7 (while ignoring the packet counts in bins 8 and 9). Configuring tmnxOamPmCfgThrDelayExclBinFrTca to the value -1 specifies that no bins are to be excluded. Configuring tmnxOamPmCfgThrDelayExclBinFrTca does not affect the value of delay bin packet counters (e.g. tmnxOamPmStsDelayDmmBinFwdCount). An attempt to change tmnxOamPmCfgThrDelayExclBinFrTca to a non-default value will be rejected if the specified bin does not exist. Bins are created using: tmnxOamPmCfgBinGroupFdBinCount, tmnxOamPmCfgBinGroupFdrBinCount, tmnxOamPmCfgBinGroupIfdvBinCount, and tmnxOamPmCfgBinGroupRowStatus. An attempt to change tmnxOamPmCfgThrDelayExclBinFrTca to a non-default value will be rejected if tmnxOamPmCfgThrDelayExclBinFrTca is less than or equal to tmnxOamPmCfgThrDelayLowestBin. An attempt to change tmnxOamPmCfgThrDelayExclBinFrTca will be rejected if the specified bin group (i.e. tmnxOamPmCfgBinGroupId) is 1. tmnxOamPmCfgThrDelayExclBinFrTca can be changed regardless of the specified bin group's administrative status (i.e. tmnxOamPmCfgBinGroupAdminStatus).

tmnxOamPmCfgBinGrpTypeDirTable contains configuration information for the delay bins to be excluded from OAM Performance Monitoring average delay calculations.

tmnxOamPmCfgBinGrpTypeDirEntry contains the delay bins to be excluded from OAM-PM average delay calculations for one OAM-PM bin group, bin type, and direction.

The value of tmnxOamPmCfgBgTyDirExclBinsFrAvg specifies the set of delay bins to be excluded from OAM-PM average delay calculations for the specified bin group, bin type, and direction. Configuring a set of delay bins using tmnxOamPmCfgBgTyDirExclBinsFrAvg allows outlier delay values to be excluded from average delay calculations. For example, suppose tmnxOamPmCfgBgTyDirExclBinsFrAvg has the value { bin0, bin9 } for bin group 255, bin type 'ifdv(3)', and the forward direction. Suppose the configured lower bounds for {bin group 255, bin type 'ifdv(3)'} are as follows. Bin Number Lower Bound (microseconds) ---------- -------------------------- 0 0 (not configurable) 1 1 2 5000 3 10000 4 15000 5 20000 6 25000 7 30000 8 35000 9 40000 Then, the average forward IFDV delay calculations for tests using bin group 255 will ignore any delay measurement that is less than 1 microsecond, or greater than or equal to 40000 microseconds. The following objects present the result of an average delay calculation: tmnxOamPmStsDelayDmmFwdAvg, tmnxOamPmStsDelayDmmBwdAvg, tmnxOamPmStsDelayDmm2wyAvg, tmnxOamPmStsDelayTwlFwdAvg, tmnxOamPmStsDelayTwlBwdAvg, and tmnxOamPmStsDelayTwl2wyAvg. Configuring tmnxOamPmCfgBgTyDirExclBinsFrAvg does not affect minimum delay or maximum delay calculations. An attempt to change tmnxOamPmCfgBgTyDirExclBinsFrAvg will be rejected if the specified bin group (i.e. tmnxOamPmCfgBinGroupId) is 1. An attempt to change tmnxOamPmCfgBgTyDirExclBinsFrAvg will be rejected if the specified bin group's administrative status (i.e. tmnxOamPmCfgBinGroupAdminStatus) is enabled.

tmnxOamPmStsBaseTable contains the base statistics for OAM Performance Monitoring Measurement Interval Data Sets. The statistics in this table are common to all test types (e.g. DMM and SLM tests).

tmnxOamPmStsBaseEntry contains the base statistics for one OAM Performance Monitoring Measurement Interval Data Set. Rows are created in this table when a test is started (e.g. using tmnxOamPmCfgDelayDmmAdminStatus and tmnxOamPmCfgDelayDmmOnDmndStatus). At that time, a row for the current interval (with the index value tmnxOamPmStsIntvlNum=1) is created for each row with a matching session name in tmnxOamPmCfgMeasIntvlTable. In addition, a row is created in this table for the test's 'miRaw(1)' interval. After that, the timed creation and destruction of rows in this table is explained using the following example. Suppose the configured number of intervals to be retained is as follows (where index columns are underlined with octothorpes, and 'tmnxOamPm' is abbreviated as '_'): _CfgSessName _CfgMeasIntvlDuration _CfgMeasIntvlsStored ############ ##################### -------------------- 'mySess1' 'mi15Minutes(2)' 3 Suppose statistics collection started at t = 0 (minutes). Suppose the following rows exist in tmnxOamPmStsBaseTable at t = 59 (minutes): _CfgSessName _StsBaseTestType _StsIntvlDuration _StsIntvlNum ############ ################ ################# ############ 'mySess1' 'dmm(1)' 'mi15Minutes(2)' 1 'mySess1' 'dmm(1)' 'mi15Minutes(2)' 2 'mySess1' 'dmm(1)' 'mi15Minutes(2)' 3 'mySess1' 'dmm(1)' 'mi15Minutes(2)' 4 The interval numbers are assigned as follows: 1 - the historical interval ended at t = 15 minutes 2 - the historical interval ended at t = 30 minutes 3 - the historical interval ended at t = 45 minutes 4 - the current interval Then, after the next 15 minute interval ends (e.g. at t = 61 minutes), the following rows will exist: _CfgSessName _StsBaseTestType _StsIntvlDuration _StsIntvlNum ############ ################ ################# ############ 'mySess1' 'dmm(1)' 'mi15Minutes(2)' 2 'mySess1' 'dmm(1)' 'mi15Minutes(2)' 3 'mySess1' 'dmm(1)' 'mi15Minutes(2)' 4 'mySess1' 'dmm(1)' 'mi15Minutes(2)' 5 The interval numbers are assigned as follows: 2 - the historical interval ended at t = 30 minutes 3 - the historical interval ended at t = 45 minutes 4 - the historical interval ended at t = 60 minutes 5 - the current interval The row with interval number 1 was destroyed, because tmnxOamPmCfgMeasIntvlsStored=3 specifies that at most three historical intervals be retained. Rows are also destroyed in this table when the corresponding tmnxOamPmCfgMeasIntvlTable row is destroyed. When the index value tmnxOamPmStsMeasIntvlDuration is 'miRaw(1)', only one interval is available (i.e. tmnxOamPmStsIntvlNum = 1). When a test is running, the measurement interval data set for a test's 'miRaw(1)' measurement interval duration can be cleared using TIMETRA-CLEAR-MIB::tmnxClearAction and tmnxClearParams. The change to the objects in the specified row is as follows. Object Change on Clear Operation ---------------------------- -------------------------------------- tmnxOamPmStsBaseOperStatus No change tmnxOamPmStsBaseSuspect Set to 'true(1)' tmnxOamPmStsBaseStartTime Set to UTC time of the clear operation tmnxOamPmStsBaseElapsedTime Set to zero tmnxOamPmStsBaseTestFramesTx Set to zero tmnxOamPmStsBaseTestFramesRx Set to zero Measurement interval data sets for measurement interval durations other than 'miRaw(1)' cannot be cleared.

The value of tmnxOamPmStsBaseTestType specifies the type of test for which statistics are to be read (e.g. 'dmm(1)').

The value of tmnxOamPmStsMeasIntvlDuration specifies the duration of the interval of the statistics to be read (e.g. 'mi15Minutes(2)').

The value of tmnxOamPmNotifThrBinLowerBound indicates the configured lower bound (in microseconds) of the MEF-35 delay bin which is the subject of the enclosing notification. When this object is part of a tmnxOamPmThrRaise notification, the notification was raised because the number of PDUs with delay greater than or equal to tmnxOamPmNotifThrBinLowerBound (in the specified measurement interval) met or exceeded the configured threshold tmnxOamPmCfgThrDelayRaise. When this object is part of a tmnxOamPmThrClear notification, the notification was raised because the number of PDUs with delay greater than or equal to tmnxOamPmNotifThrBinLowerBound (in the specified measurement interval) was less than or equal to the configured threshold tmnxOamPmCfgThrDelayClear. For example, suppose an OAM-PM delay raise threshold is configured with tmnxOamPmCfgThrDelayRaise = 1000 and tmnxOamPmCfgThrDelayLowestBin = 6. Suppose the configured lower bound (i.e. tmnxOamPmCfgBinLowerBound) for the specified bin 6 is 30,000 microseconds. Then, if the count of PDUs with delay at or above 30,000 microseconds (e.g. tmnxOamPmStsDelayDmmBin2wyCount) is 1000, and a TCA is raised, this object will report 30,000. This value must be ignored if the enclosing notification is a loss TCA (i.e. when tmnxOamPmNotifThrType is not 'delay(1)').

[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.

[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.
