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.
