! 1376: DESCRIPTION
! 1377: "This table contains one entry per interface. It defines
! 1378: objects which allow a network manager to instruct an agent
! 1379: to test an interface for various faults. Tests for an
! 1380: interface are defined in the media-specific MIB for that
! 1381: interface. After invoking a test, the object ifTestResult
! 1382: can be read to determine the outcome. If an agent can not
! 1383: perform the test, ifTestResult is set to so indicate. The
! 1384: object ifTestCode can be used to provide further test-
! 1385: specific or interface-specific (or even enterprise-specific)
! 1386: information concerning the outcome of the test. Only one
! 1387: test can be in progress on each interface at any one time.
! 1388: If one test is in progress when another test is invoked, the
! 1389: second test is rejected. Some agents may reject a test when
! 1390: a prior test is active on another interface.
! 1391:
! 1392: Before starting a test, a manager-station must first obtain
! 1393: 'ownership' of the entry in the ifTestTable for the
! 1394: interface to be tested. This is accomplished with the
! 1395: ifTestId and ifTestStatus objects as follows:
! 1396:
! 1397: try_again:
! 1398: get (ifTestId, ifTestStatus)
! 1399: while (ifTestStatus != notInUse)

! 1415: ifTestOwner = 'my-IP-address') == FAILURE)
! 1416: /*

! 1430: set(ifTestType = test_to_run);
! 1431:
! 1432: wait for test completion by polling ifTestResult
! 1433:
! 1434: when test completes, agent sets ifTestResult
! 1435: agent also sets ifTestStatus = 'notInUse'
! 1436:
! 1437: retrieve any additional test results, and ifTestId
! 1438:
! 1439: if (ifTestId == lock_value+1) results are valid
! 1440:
! 1441: A manager station first retrieves the value of the
! 1442: appropriate ifTestId and ifTestStatus objects, periodically
! 1443: repeating the retrieval if necessary, until the value of
! 1444: ifTestStatus is 'notInUse'. The manager station then tries
! 1445: to set the same ifTestId object to the value it just
! 1446: retrieved, the same ifTestStatus object to 'inUse', and the
! 1447: corresponding ifTestOwner object to a value indicating
! 1448: itself. If the set operation succeeds then the manager has
! 1449: obtained ownership of the ifTestEntry, and the value of the
! 1450: ifTestId object is incremented by the agent (per the
! 1451: semantics of TestAndIncr). Failure of the set operation
! 1452: indicates that some other manager has obtained ownership of
! 1453: the ifTestEntry.
! 1454:
! 1455: Once ownership is obtained, any test parameters can be
! 1456: setup, and then the test is initiated by setting ifTestType.
! 1457: On completion of the test, the agent sets ifTestStatus to
! 1458: 'notInUse'. Once this occurs, the manager can retrieve the
! 1459: results. In the (rare) event that the invocation of tests
! 1460: by two network managers were to overlap, then there would be
! 1461: a possibility that the first test's results might be
! 1462: overwritten by the second test's results prior to the first
! 1463:
! 1464: results being read. This unlikely circumstance can be
! 1465: detected by a network manager retrieving ifTestId at the
! 1466: same time as retrieving the test results, and ensuring that
! 1467: the results are for the desired request.
! 1468:
! 1469: If ifTestType is not set within an abnormally long period of
! 1470: time after ownership is obtained, the agent should time-out
! 1471: the manager, and reset the value of the ifTestStatus object
! 1472: back to 'notInUse'. It is suggested that this time-out
! 1473: period be 5 minutes.
! 1474:
! 1475: In general, a management station must not retransmit a
! 1476: request to invoke a test for which it does not receive a
! 1477: response; instead, it properly inspects an agent's MIB to
! 1478: determine if the invocation was successful. Only if the
! 1479: invocation was unsuccessful, is the invocation request
! 1480: retransmitted.
! 1481:
! 1482: Some tests may require the interface to be taken off-line in
! 1483: order to execute them, or may even require the agent to
! 1484: reboot after completion of the test. In these
! 1485: circumstances, communication with the management station
! 1486: invoking the test may be lost until after completion of the
! 1487: test. An agent is not required to support such tests.
! 1488: However, if such tests are supported, then the agent should
! 1489: make every effort to transmit a response to the request
! 1490: which invoked the test prior to losing communication. When
! 1491: the agent is restored to normal service, the results of the
! 1492: test are properly made available in the appropriate objects.
! 1493: Note that this requires that the ifIndex value assigned to
! 1494: an interface must be unchanged even if the test causes a
! 1495: reboot. An agent must reject any test for which it cannot,
! 1496: perhaps due to resource constraints, make available at least
! 1497: the minimum amount of information after that test
! 1498: completes."
