DVB-MGTR101290-MIB: View SNMP OID List / Download MIB

DVB Measurement Group MIB to support TR 101 290. This tr101290 module contains measurements defined in TR 101 290.

The current date and time at the location of the measurement equipment. It is highly desirable that the offset from UTC should be included. It is possible to set the time and date through this object, but it is expected that most systems will incorporate a more accurate method for doing this.

The persistence timer used with Event errors. An Event error test remains in the 'fail' state for this length of time after the occurrence of the Event.

Table which controls the RF modulation expected to be received on each input.

Row specification

RF input whose mode of operation is to be set

The type of signal the instrument should expect at its input.

Table reserved for future specification of synchronized timing.

Row specification

Transport Stream number to which the objects in this row apply.

This object is reserved pending future standardisation of timestamping of Transport Streams.

This trap is sent when a test which is not associated with a measurement fails. This trap is triggered by the transition of the '...State' or '...TestState' object associated with the test to the 'fail' state from any other state. Transmission of the trap is subject to rate control and to the enable status of each test.

Trap which is sent when a test which is associated with a measurement fails. This trap is triggered by the transition of the '...State' or '...TestState' object associated with the test to the 'fail' state from any other state. Transmission of the trap is subject to rate control and to the enable status of each test.

Trap which is sent when a measurement value becomes unavailable. This trap is triggered by the transition of the '...MeasurementState' object associated with the measurement to the 'unknown' state from any other state. Transmission of the trap is subject to rate control.

Table of trap control information for each input

Row specification

Each Transport Stream input has separate trap control parameters. This object identifies the Transport Stream input to which the trap control parameters apply

In the case of a testFailTrap or a measurementFailTrap, this object holds the OID of the '...State' or '...TestState' object whose transition to 'fail' has triggered the trap. In the case of a measurementUnknownTrap, this object holds the OID of the '...MeasurementState' object whose transition to 'unknown' has triggered the trap. This object is present for the formal purpose of defining the variable bindings returned with the traps. It is not accessible for normal reading.

In the case of a testFailTrap or a measurementFailTrap, at the moment when the trap is generated, the value of the '...LatestError' object associated with the test which caused the trap is copied here. In the case of a measurementUnknownTrap, the time at which the measurement became unknown is copied here. This object is present for the formal purpose of defining the variable bindings returned with the traps. It is not accessible for normal reading.

At the moment when a measurementFailTrap is generated, the value of this object is set from the '...Value' object associated with the measurement which caused the trap. Where a measurement returns multiple values, the value which is copied here is the one which is compared with the threshold(s) to generate the test result. The measurement units are the same as those of the source object. This object is present for the formal purpose of defining the variable bindings returned with the traps. It is not accessible for normal reading.

This object is used for rate control of traps, preventing overload of the management network by transmission of an excessive number of traps. The value 'disabled' means that traps are never sent. The value 'enabled' means that a trap will be sent when triggered. When a trap is sent, the agent changes the value of this object to 'enabledThrottled'. In this state the agent will not send any more traps. The agent automatically changes the value back to 'enabled' when the time specified by trapControlPeriod expires. A management application may set the value to 'enabled' at any time, but must never set the value to 'enabledThrottled'. This single status applies to all the trap types, so for example if an agent sends a testFailTrap it will not send a measurementFailTrap until the trapControlPeriod expires.

An agent will ensure that the interval between sending traps is no shorter than this time period. The management system can override this by setting trapControlRateStatus back to 'enabled' within the time period.

This bit string contains a summary of all the test failures. If the bit for the test is set to one, that test is in a fail state. When a trap is being generated, the agent should ensure that this information is as up to date as possible, without causing undue delay in sending the trap.

The Transport Stream input whose change triggered the current trap. This information can also be obtained by analysing the trapControlOID, but trapInput provides the information directly. This object is present for the formal purpose of defining the variable bindings returned with the traps. It is not accessible for normal reading.

The capabilities of the agent are expressed in relation to a specific revision of the tr101290 MIB module. The date and time here must exactly match one of the revision dates in the MODULE-IDENTITY section of the MIB.

The tsTestsSummaryTable provides access to the state of all of the Transport Stream tests enumerated in IndexTransportStreamTest. The status relates to the whole Transport Stream. In the case of tests which have a status per PID, the tsTestsSummaryTable gives the 'worst' status across all the PIDs and the status for each PID is available in tsTestsPIDTable.

Row specification

Transport Stream on which the test is made

Specifies the test, see definition of IndexTransportStreamTest. Rows in the table exist only for tests which are actually implemented by the measuring equipment.

This gives the overall pass/fail state of the test. For tests which have a state per PID, tsTestsSummaryState contains the highest numeric value of all the tsTestsPIDState objects for the test.

Determines whether this test and associated traps are enabled. Setting tsTestsSummaryEnable affects tsTestsPIDEnable in tsTestsPIDTable. When tsTestsSummaryEnable is set, all existing instances of tsTestsPIDEnable are set to the same value. Any new rows in tsTestsPIDTable which are created will also have this value for tsTestsPIDEnable (unless the row is created by explicitly setting the value of tsTestsPIDEnable).

Count of the number of times this error has occurred. For Status errors this is the number of times the TestState has entered the fail state from some other state. For Error events this is the total number of events; the persistence timer is not taken into account by the counter.

This table makes available the PCR_FO, PCR_DR, PCR_OJ and PCR_AC measurements.

Row specification

Input on which the measurement is made

PID (plus one) in the Transport Stream carrying (or expected to carry) PCRs.

Indicates the validity of the measurement

The units for the measured value depend on the measurement: PCR_FO Hz PCR_DR Hz/s Values for PCR_OJ and PCR_AC are not provided as they occur too quickly to be usefully retrieved via SNMP. For these measurements, the MeasurementState is always 'unknown'. However, the threshold tests are expected to work correctly for these measurements.

'tau' value for Transport Stream bit rate measurement. The MIB provides very flexible ways of setting the bit rate measurement parameters tau, N and element for the Transport Stream, services, PIDs and for individual services and PIDs. Real measurement equipment can be expected to provide much less flexibility. Management software should anticipate this by either being statically aware of the capabilities of the agent or by checking that preference settings have been accepted by reading them back after each attempt to set them.

A 'fail' is an approximate indication that the system is in a period of link unavailable time (LUAT). 'fail' is indicated as soon as a trigger period for link unavailable time completes. 'pass' is indicated as soon as a trigger period for link available time completes. This necessarily differs from the strict definition of LUAT because the measuring equipment is unable to look into the future.
