MEF-SOAM-PM-MIB Table View

This table is an extension of the dot1agCfmMepTable and rows
are automatically added or deleted from this table based upon row
creation and destruction of the dot1agCfmMepTable. 
          
This table represents the local MEP PM configuration table. The
primary purpose of this table is provide local parameters for the 
SOAM PM function found in [Y.1731] and [MEF SOAM-PM] and instantiated
at a MEP.

This table includes configuration objects and operations for the 
Frame Loss Measurement function defined in [Y.1731] and [MEF SOAM-PM]. 
          
Each row in the table represents a Loss Measurement session for
the defined MEP. This table uses four indices. The first three indices
are the indices of the Maintenance Domain, MaNet, and MEP tables. The 
fourth index is the specific LM session on the selected MEP. A
Loss Measurement session is created on an existing MEP by first 
accessing the mefSoamPmMepOperNextIndex object and using this value as 
the mefSoamLmCfgIndex in the row creation.
          
Some writable objects in this table are only applicable in certain cases
(as described under each object), and attempts to write values for them 
in other cases will be ignored.
          
The writable objects in this table need to be persistent upon reboot 
or restart of a device.

This object contains the last measured results for a SOAM Loss 
Measurement session.
          
Each row in the table represents a Loss Measurement session for
the defined MEP. This table uses four indices. The first three indices
are the indices of the Maintenance Domain, MaNet, and MEP tables. The 
fourth index is the specific LM session on the selected MEP.
          
Instances of this managed object are created automatically
by the SNMP Agent when the Loss Measurement session is running.
          
Each object in this table applies only if the corresponding bit is set in 
mefSoamLmCfgMeasurementEnable.
          
The objects in this table do not need to be persistent upon reboot
or restart of a device.

This object contains the current results for a SOAM Loss Measurement
session for availability statistics gathered during the interval 
indicated by mefSoamLmCfgAvailabilityMeasurementInterval.
          
Each row in the table represents a Loss Measurement session for
the defined MEP. This table uses four indices. The first three indices
are the indices of the Maintenance Domain, MaNet, and MEP tables. The 
fourth index is the specific LM session on the selected MEP.
          
Instances of this managed object are created automatically
by the SNMP Agent when the Loss Measurement session is running.
          
The objects in this table apply regardless of the value of 
mefSoamLmCfgType unless otherwise specified in the object description.
          
Except for mefSoamLmCurrentAvailStatsIndex,
mefSoamLmCurrentAvailStatsStartTime, mefSoamLmCurrentAvailStatsElapsedTime
and mefSoamLmCurrentAvailStatsSuspect, each object in this table applies
only if the corresponding bit is set in mefSoamLmCfgMeasurementEnable.
          
The objects in this table may be persistent upon reboot or restart
of a device.

This table contains the results for the current Measurement
Interval in a SOAM Loss Measurement session gathered during the interval
indicated by mefSoamLmCfgMeasurementInterval.
          
A row in this table is created automatically
by the SNMP Agent when the Loss Measurement session is configured.
          
Each row in the table represents the current statistics for a Loss
Measurement session for the defined MEP. This table uses four indices. 
The first three indices are the indices of the Maintenance Domain, MaNet,
and MEP tables. The fourth index is the specific LM session on the 
selected MEP. There may be more than one LM session per MEP. The
main use case for this is to allow multiple CoS instances to be 
operating simultaneously for a MEP.
          
The objects in this table apply regardless of the value of 
mefSoamLmCfgType unless otherwise specified in the object description.
          
Except for mefSoamLmCurrentStatsIndex, mefSoamLmCurrentStatsStartTime,
mefSoamLmCurrentStatsElapsedTime and mefSoamLmCurrentStatsSuspect, 
each object in this table applies only if the corresponding bit is set in 
mefSoamLmCfgMeasurementEnable.
          
          
The objects in this table do not need to be persistent upon reboot or
restart of a device.

This table contains the results for availability history Measurement
Intervals in a SOAM Loss Measurement session.
          
Rows of this table object are created automatically
by the SNMP Agent when the Loss Measurement session is running and a 
Measurement Interval is completed.
          
Each row in the table represents the history statistics for a Loss
Measurement session availability Measurement Interval for the defined
MEP. This table uses five indices. The first three indices are the indices of
the Maintenance Domain, MaNet, and MEP tables. The fourth index is the
specific LM session on the selected MEP. The fifth index index the
specific Measurement Interval.
          
At least 32 completed Measurement Intervals are to be supported. 96
completed Measurement Intervals are recommended to be supported. If
there are at least 32 rows in the table and a new Measurement Interval
completes and a new row is to be added to the table, the oldest completed
Measurement Interval can be deleted (row deletion). If the availability
Measurement Interval is other than 15 minutes then a minimum of 8 hours of 
completed Measurement Intervals are to be supported and 24 hours are
recommended to be supported.
          
Except for mefSoamLmHistoryAvailStatsIndex, 
mefSoamLmHistoryAvailStatsEndTime, mefSoamLmHistoryAvailStatsElapsedTime and 
mefSoamLmHistoryAvailStatsSuspect, each object in this table applies only
if the corresponding bit is set in mefSoamLmCfgMeasurementEnable.
          
The rows and objects in this table are to be persistent upon reboot 
or restart of a device.

This table contains the results for history Measurement
Intervals in a SOAM Loss Measurement session.
          
Rows of this table object are created automatically
by the SNMP Agent when the Loss Measurement session is running and a 
Measurement Interval is completed.
          
Each row in the table represents the history statistics for a Loss
Measurement session Measurement Interval for the defined MEP. This
table uses five indices. The first three indices are the indices of
the Maintenance Domain, MaNet, and MEP tables. The fourth index is the
specific LM session on the selected MEP. The fifth index index the
specific Measurement Interval.
          
At least 32 completed Measurement Intervals are to be supported. 96
completed Measurement Intervals are recommended to be supported. If
there are at least 32 rows in the table and a new Measurement Interval
completes and a new row is to be added to the table, the oldest completed
Measurement Interval may be deleted (row deletion). If the measurement
interval is other than 15 minutes then a minimum of 8 hours of 
completed Measurement Intervals are to be supported and 24 hours are
recommended to be supported.
          
Except for mefSoamLmHistoryStatsIndex, mefSoamLmHistoryStatsEndTime,
mefSoamLmHistoryStatsElapsedTime and mefSoamLmHistoryStatsSuspect, 
each object in this table applies only if the corresponding bit is set in 
mefSoamLmCfgMeasurementEnable.
          
The rows and objects in this table are to be persistent upon reboot 
or restart of a device.

This table contains the list of Loss Measurement configuration threshold
values for LM Performance Monitoring.
          
The main purpose of the threshold configuration table is to configure
threshold alarm notifications indicating that a specific performance
metric is not being met.
          
Each row in the table represents a Loss Measurement session threshold
set for the defined MEP. This table uses five indices. The first three
indices are the indices of the Maintenance Domain, MaNet, and MEP tables.
The fourth index is the specific LM session on the selected MEP. The
fifth index is the specific threshold set number. 
          
Rows in this table are not created automatically. A row is created in
this table to set up a threshold set on a configured MEP that has a
configured LM session.
          
If two managers try to 'create' the same row at the same time, the first
creation would succeed, the second creation attempt would result in an
error. The second creation attempt would then need to select a new index
value to successfully create a new row.
          
An NE needs to support at least one threshold set for NE SOAM PM compliance. A 
second threshold set on the NE is desirable. More than two threshold 
sets can be configured on the NE if supported on the NE.
          
All the objects in the row have a default value that disables the
particular threshold measurement. In order to enable a threshold 
measurement the particular bit in the mefSoamLmThresholdCfgEnable object
is to be set to '1' and the selected threshold measurement is to have
a threshold value configured. Non-configured threshold measurements
are disabled by default.
          
The writable objects in this table need to be persistent upon reboot 
or restart of a device.

This table includes configuration objects and operations for the 
Delay Measurement function.  
          
Each row in the table represents a Delay Measurement session for
the defined MEP. This table uses four indices. The first three indices
are the indices of the Maintenance Domain, MaNet, and MEP tables. The 
fourth index is the specific DM session on the selected MEP. 
          
A Delay Measurement session is created on an existing MEP by first 
accessing the mefSoamDmOperNextIndex object and using this value as 
the mefSoamDmCfgIndex in the row creation.
          
Some writable objects in this table are only applicable in certain cases
(as described under each object), and attempts to write values for them 
in other cases will be ignored.
          
The writable objects in this table need to be persistent upon reboot 
or restart of a device.

This table includes configuration objects for the Delay Measurement 
bins to collect stats.
          
Each row in the table is automatically created when the Delay
Measurement session is defined for the selected MEP. The number of rows
created is based upon three items: the DM type, the number of bins
defined for each type, and whether bins are enabled for each type.
          
The first four indices are the same as used to create the DM session:
Maintenance Domain, MaNet, MEP identification, and mefSoamDmCfgIndex. The
fifth index is the type of bin, and the sixth index is the bin number.
          
For a dmDmm session all nine types of bins can be created. For a dm1DmmTx
session no bins are created. For a dm1DmmRx session only types 
forwardFrameDelay, forwardIfdv, and forwardFrameDelayRange can be created.
          
The number of bins created for a bin type is based upon: the 
mefSoamDmCfgNumMeasBinsPerFrameDelayInterval object, the 
mefSoamDmCfgNumMeasBinsPerInterFrameDelayVariationInterval object, the 
mefSoamDmCfgNumMeasBinsPerFrameDelayRangeInterval object, and
the mefSoamDmCfgMeasurementEnable object.
          
For instance, if a dmDmm session with Bins per Frame Delay Interval 
set to 5, Bins per Frame Delay Variation Interval set to 3, and Frame 
Delay Range set to 2 (default), all of the appropriate bits set in
mefSoamDmMeasurementCfgEnable, the following number of rows would be
created:
          
For bin types TwoWayFrameDelay(1), forwardFrameDelay(2), and 
backwardFrameDelay(3) = 5 bins * 3 types = 15 rows
          
For bin types TwoWayIfdv(4), forwardIfdv(5), backwardIfdv(6) = 
3 bins * 3 types = 9 rows.         
          
For bins types twoWayFrameDelayRange(7), forwardFrameDelayRange(8),
backwardFrameDelayRange(9) =
2 bins * 3 types = 6 rows.
          
This gives a total of 30 rows created for the DMM session example.
          
Each value in the bin defaults to 5000us greater than the previous bin,
with the first bin default value set to 0.
          
For the delay example above (5 bins), the following default values 
would be written to the bins:
      bin 1:     0  (range is 0us <= measurement < 5,000us)
      bin 2:  5000  (range is 5,000us <= measurement < 10,000us)
      bin 3: 10000  (range is 10,000us <= measurement < 15,000us)
      bin 4: 15000  (range is 15,000us <= measurement < 20,000us)
      bin 5: 20000  (range is 20,000us <= measurement < infinity)
          
For the delay variation example above (3 bins), the following default 
values would be written to the bins:
      bin 1:     0  (range is 0us <= measurement < 5,000us)
      bin 2:  5000  (range is 5,000us <= measurement < 10,000us)
      bin 3: 10000  (range is 10,000us <= measurement < infinity)
          
For the frame delay range example above (2 bins), the following default 
values would be written to the bins:
      bin 1:     0  (range is 0us <= measurement < 5,000us)
      bin 2:  5000  (range is 5,000us <= measurement < infinity)
          
The writable objects in this table need to be persistent upon reboot 
or restart of a device. 
          
Rows are only created if the corresponding measurement type has been enabled 
via the mefSoamDmCfgMeasurementEnable object.

values for DM Performance Monitoring.
          
The main purpose of the threshold configuration table is to configure
threshold alarm notifications indicating that a specific performance
metric is not being met.
          
Each row in the table represents a Delay Measurement session threshold
set for the defined MEP. This table uses five indices. The first three
indices are the indices of the Maintenance Domain, MaNet, and MEP tables.
The fourth index is the specific DM session on the selected MEP. The

An NE needs to support at least one threshold set for NE SOAM PM compliance. A 
second threshold set on the NE is desirable. More than two threshold 
sets on the NE can be configured if supported on the NE.
          
All the objects in the row have a default value that disables the
particular threshold measurement. In order to enable a threshold 
measurement the particular bit in the mefSoamDmThresholdCfgEnable object
is to be set to '1' and the selected threshold measurement is to have
a threshold value configured. Non-configured threshold measurements
are disabled by default.
