+            "The table containing information on the relationships
+            between the multiple sub-layers of network interfaces.  In
+            particular, it contains information on which sub-layers run
+            'on top of' which other sub-layers, where each sub-layer
+            corresponds to a conceptual row in the ifTable.  For
+            example, when the sub-layer with ifIndex value x runs over
+            the sub-layer with ifIndex value y, then this table
+            contains:
+
+              ifStackStatus.x.y=active
+
+            For each ifIndex value, I, which identifies an active
+            interface, there are always at least two instantiated rows
+            in this table associated with I.  For one of these rows, I
+            is the value of ifStackHigherLayer; for the other, I is the
+            value of ifStackLowerLayer.  (If I is not involved in
+            multiplexing, then these are the only two rows associated
+            with I.)
+
+            For example, two rows exist even for an interface which has
+            no others stacked on top or below it:

+            information concerning the outcome of the test.  Only one
+            test can be in progress on each interface at any one time.
+            If one test is in progress when another test is invoked, the
+            second test is rejected.  Some agents may reject a test when
+            a prior test is active on another interface.
+
+            Before starting a test, a manager-station must first obtain
+            'ownership' of the entry in the ifTestTable for the
+            interface to be tested.  This is accomplished with the
+            ifTestId and ifTestStatus objects as follows:
+
+          try_again:
+              get (ifTestId, ifTestStatus)
+              while (ifTestStatus != notInUse)
+                  /*
+                   * Loop while a test is running or some other
+                   * manager is configuring a test.
+                   */
+                  short delay
+                  get (ifTestId, ifTestStatus)
+              }
+
+              /*
+               * Is not being used right now -- let's compete
+               * to see who gets it.
+               */
+              lock_value = ifTestId
+
+              if ( set(ifTestId = lock_value, ifTestStatus = inUse,
+                       ifTestOwner = 'my-IP-address') == FAILURE)
+                  /*
+                   * Another manager got the ifTestEntry -- go
+                   * try again
+                   */
+                  goto try_again;
+
+              /*
+               * I have the lock
+               */
+              set up any test parameters.
+
+              /*
+               * This starts the test
+               */
+              set(ifTestType = test_to_run);
+
+              wait for test completion by polling ifTestResult
+
+              when test completes, agent sets ifTestResult
+                   agent also sets ifTestStatus = 'notInUse'
+
+              retrieve any additional test results, and ifTestId
+
+              if (ifTestId == lock_value+1) results are valid
+
+            A manager station first retrieves the value of the
+            appropriate ifTestId and ifTestStatus objects, periodically
+            repeating the retrieval if necessary, until the value of
+            ifTestStatus is 'notInUse'.  The manager station then tries
+            to set the same ifTestId object to the value it just
+            retrieved, the same ifTestStatus object to 'inUse', and the
+            corresponding ifTestOwner object to a value indicating
+            itself.  If the set operation succeeds then the manager has
+            obtained ownership of the ifTestEntry, and the value of the
+            ifTestId object is incremented by the agent (per the
+            semantics of TestAndIncr).  Failure of the set operation
+            indicates that some other manager has obtained ownership of
+            the ifTestEntry.
+
+            Once ownership is obtained, any test parameters can be
+            setup, and then the test is initiated by setting ifTestType.
+            On completion of the test, the agent sets ifTestStatus to
+            'notInUse'.  Once this occurs, the manager can retrieve the
+            results.  In the (rare) event that the invocation of tests
+            by two network managers were to overlap, then there would be
+            a possibility that the first test's results might be
+            overwritten by the second test's results prior to the first
+
+            results being read.  This unlikely circumstance can be
+            detected by a network manager retrieving ifTestId at the
+            same time as retrieving the test results, and ensuring that
+            the results are for the desired request.
+
+            If ifTestType is not set within an abnormally long period of
+            time after ownership is obtained, the agent should time-out
+            the manager, and reset the value of the ifTestStatus object
+            back to 'notInUse'.  It is suggested that this time-out
+            period be 5 minutes.
+
+            In general, a management station must not retransmit a
+            request to invoke a test for which it does not receive a
+            response; instead, it properly inspects an agent's MIB to
+            determine if the invocation was successful.  Only if the
+            invocation was unsuccessful, is the invocation request
+            retransmitted.
+
+            Some tests may require the interface to be taken off-line in
+            order to execute them, or may even require the agent to
+            reboot after completion of the test.  In these
+            circumstances, communication with the management station
+            invoking the test may be lost until after completion of the
+            test.  An agent is not required to support such tests.
+            However, if such tests are supported, then the agent should
+            make every effort to transmit a response to the request
+            which invoked the test prior to losing communication.  When
+            the agent is restored to normal service, the results of the
+            test are properly made available in the appropriate objects.
+            Note that this requires that the ifIndex value assigned to
+            an interface must be unchanged even if the test causes a
+            reboot.  An agent must reject any test for which it cannot,
+            perhaps due to resource constraints, make available at least
+            the minimum amount of information after that test
+            completes."
