    DESCRIPTION 
        "This data type is used to model an administratively
         assigned name of the owner of a resource.  This information
         is taken from the NVT ASCII character set.  It is suggested
         that this name contain one or more of the following: ASCII
         form of the manager station's transport address, management
         station name (e.g., domain name), network management
         personnel's name, location, or phone number.  In some cases
         the agent itself will be the owner of an entry.  In these
         cases, this string shall be set to a string starting with

    DESCRIPTION 
        "This textual convention is an extension of the
         InterfaceIndex convention.  The latter defines a greater
         than zero value used to identify an interface or interface
         sub-layer in the managed system.  This extension permits the
         additional value of zero.  the value zero is object-specific
         and must therefore be defined as part of the description of
         any object which uses this syntax.  Examples of the usage of
         zero might include situations where interface was unknown,
         or when none or all interfaces need to be referenced."

         then ifOperStatus should change to up(1) if the interface is
         ready to transmit and receive network traffic; it should
         change to dormant(5) if the interface is waiting for
         external actions (such as a serial line waiting for an
         incoming connection); it should remain in the down(2) state
         if and only if there is a fault that prevents it from going
         to the up(1) state; it should remain in the notPresent(6)

        "This table contains one entry per interface.  It defines

         to test an interface for various faults.  Tests for an
         interface are defined in the media-specific MIB for that
         interface.  After invoking a test, the object ifTestResult
         can be read to determine the outcome.  If an agent can not
         perform the test, ifTestResult is set to so indicate.  The
         object ifTestCode can be used to provide further test-
         specific or interface-specific (or even enterprise-specific)
         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:

           get (ifTestId, ifTestStatus)
           while (ifTestStatus != notInUse)

               get (ifTestId, ifTestStatus)

            * Is not being used right now -- let's compete
            * to see who gets it.

                    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."
