          This memo defines an portion of the Management Information
          Base (MIB) for use with network management protocols in the
          Internet community.  In particular, it describes objects used
          for testing systems and interfaces. This memo defines the
          following:
          
          0    A general mechanism to initiate tests
          
          0    A capability to provide and store test results
          
          0    A capability to inventory the tests that are supported by
               an agent
          
          This memo does not specify individual tests. Such tests are
          subject of separate system- or media-specific specifications.
          
          This memo replaces the objects defined in the ifTestGroup of
          RFC2233[RFC2233] which have been deprecated.

          3.  The SNMP Management Framework
          
          The SNMP Management Framework presently consists of five major
          components:
          
              o   An overall architecture, described in RFC 2571
                  [RFC2571].
          
              o   Mechanisms for describing and naming objects and
                  events for the purpose of management. The first
                  version of this Structure of Management Information
                  (SMI) is called SMIv1 and described in STD 16, RFC
                  1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC
                  1215 [RFC1215]. The second version, called SMIv2, is
                  described in STD 58, RFC 2578 [RFC2578], RFC 2579
                  [RFC2579] and RFC 2580 [RFC2580].
          
              o   Message protocols for transferring management
                  information. The first version of the SNMP message
                  protocol is called SNMPv1 and described in STD 15, RFC
                  1157 [RFC1157]. A second version of the SNMP message
                  protocol, which is not an Internet standards track
                  protocol, is called SNMPv2c and described in RFC 1901
                  [RFC1901] and RFC 1906 [RFC1906]. The third version of
                  the message protocol is called SNMPv3 and described in
                  RFC 1906 [RFC1906], RFC 2572 [RFC2572] and RFC 2574
                  [RFC2574].
          
              o   Protocol operations for accessing management
                  information. The first set of protocol operations and
                  associated PDU formats is described in STD 15, RFC
                  1157 [RFC1157]. A second set of protocol operations
                  and associated PDU formats is described in RFC 1905
                  [RFC1905].
          
              o   A set of fundamental applications described in RFC
                  2573 [RFC2573] and the view-based access control
                  mechanism described in RFC 2575 [RFC2575].
          
                  A more detailed introduction to the current SNMP
                  Management Framework can be found in RFC 2570
                  [RFC2570].
          
                  Managed objects are accessed via a virtual information
                  store, termed the Management Information Base or MIB.

                  Objects in the MIB are defined using the mechanisms
                  defined in the SMI.
          
                  This memo specifies a MIB module that is compliant to
                  the SMIv2. A MIB conforming to the SMIv1 can be
                  produced through the appropriate translations. The
                  resulting translated MIB must be semantically
                  equivalent, except where objects or events are omitted
                  because no translation is possible (use of Counter64).
                  Some machine readable information in SMIv2 will be
                  converted into textual descriptions in SMIv1 during
                  the translation process. However, this loss of machine
                  readable information is not considered to change the
                  semantics of the MIB.

          4.  Experience with the Interfaces Test Group
          
          The ifTestGroup of objects defined in RFC2233 has not been
          used widely. Some cited problems were:
          
          
          0    Few standard tests had been defined to date.
          
          0    Some well known tests had already been written on a
               media-specific basis, e.g., DS1 loopback.  The
               ifTestGroup allowed for interface testing only.
          
          0    A logging capability was missing.
          
          As a result, the ifTestGroup and associated ifTestTable have
          been deprecated. However, since renewed interest was expressed
          in a generic testing capability, specifically in the
          development of MIBs for managing Asynchronous Transfer Mode
          interfaces, a set of requirements have been defined that form
          the basis for the design of the generic Test MIB defined in
          this memo.
          
          
          5.  Requirements for a Generic Test MIB
          
          This section describes the requirements that have been
          identified for a generic test MIB.
          
          5.1.  Test Identification
          
          The system defined in RFC2233 to identify tests relies on
          OBJECT IDENTIFIERs. This system is flexible in that it allows
          additional tests to be defined over time and autonomously by
          vendors, removing the need to register test types in a single
          place. This mechanism for test identification has been
          retained.

          5.2.  Test Targets
          
          With the advent of an increasing number of non-interface
          related MIB modules it is desirable to define a test
          capability that allows testing of interfaces and non-interface
          physical entities. The following possibilities were
          considered:
          
          a)   Separate test capabilities for interface tests and other
               tests.
          
          b)   The use of a single test capability where the test target
               would be defined within the test table.
          
          This memo uses the latter approach and uses an object with the
          syntax RowPointer to identify test targets. (Initially, the
          use of the Entity MIB[RFC2037] was considered for
          identification of test targets, but this was abandoned because
          this would require support of the Entity MIB for testing
          purposes.)
          
          Tests are listed in the testTable. The entries in the
          testTable are distinguished through the value of a simple
          integer called testIndex.
          
          
          5.3.  Logging Results
          
          A logging capability of test results serves to store the test
          results for some period of time. Two mechanisms were
          considered:
          
          1)   Separate the test capability and the log.
          
          2)   Combine the test capability and the log in a single
               table.
          
          The log length is necessarily limited. The following choices
          were considered:
          
          1)   Age the entries.
          
          2)   Limit by the number of entries.

          3)   A system that allows either 1) or 2).
          
          For efficiency reasons this MIB module chooses a system where
          the test and logging capability have been combined in a single
          table (testTable). The log length is limited by a read-write
          object (testTableMaxSize).
          
          This MIB module also defines a notification, testComplete,
          which contains the same information as the log entry.
          Therefore, an agent with limited resources can limit the
          maximum size of the log to a very few number of entries and
          rely on a management application to receive and log the
          testComplete notifications.
          
          
          5.4.  Log Searching
          
          Efficient searching in a log is a key to its effectiveness.
          The following possibilities were considered:
          
          a)   Sort on age of the entries.
          
          b)   Sort on test type.
          
          c)   Sort on combinations of the above.
          
          This MIB module chooses for the index testIndex, which is an
          integer identifier for an invocation of a test. To obtain a
          new testIndex a manager retrieves the value of testIndexNext.
          Each time this object is read the next lower available value
          is provided. This addresses the requests that are expected to
          be most common:
          
          0    What is the result of test (testIndex)?
          
          0    What are the results of the last n tests?
          
          Since the testIndex has been defined as decreasing, this
          approach will order log entries by time, newest to oldest. The
          possibility of testId wrapping is minimized by having it
          restart at its maximum value and when the agent restarts. When
          a manager is interested in a specific test, a specific get-
          request may be issued. When a manager is interested in the
          latest n tests for the system, getnext/bulk starting from
          (testIndex) provides the approximate answer.

                    The value 0 indicates that no unassigned entries
                    are available. To obtain the testIndex
                    value for a new entry, the manager issues a
                    management protocol retrieval operation to obtain
                    the current value of this object.  After each
                    retrieval, the agent should modify the value to
                    the next lower unassigned index. If the agent is
                    restarted this object shall be set to its highest
                    value.
                    The agent does not require that retrieved values

                    they are used in the order of their retrieval.

                DESCRIPTION
                   "This table is used to initiate tests and to log
                    test results.
                    An entry in this table corresponds to an instance
                    of a test. A test is invoked by creating a row with
                    the appropriate test attributes and using
                    testRowStatus to start a test. After invoking a test,
                    the object testResult can be read to determine the
                    outcome.  If an agent can not perform the test,
                    testResult is set accordingly.  The testCode can
                    be used to provide further test-specific or entity-
                    specific (or even enterprise-specific) information
                    concerning the outcome of the test.  Only one test
                    can be in progress on each entity at any one time.
                    If one test is in progress when another test is
                    invoked, the second test is rejected (e.g., for an
                    SNMPv2 SET operation an inconsistentValue error
                    is returned).  Some agents may reject a test when
                    a prior test is active on another entity.
          
                    Before starting a test, a manager-station must first
                    obtain 'ownership' of the entry in the testTable for
                    the entity to be tested.  This is accomplished by
                    retrieving the value of testIndexNext. This value
                    entitles the manager to create a row in the
                    testTable with the value of testIndex being equal to
                    the retrieved value of testIndexNext and testOwner
                    set to the appropriate value for the manager.
                    A prudent sequence to obtain 'ownership' of a
                    testTable entry and to minimize collisions (e.g., with
                    a manager not following the rules) is as follows:
                    (1) Retrieve testIndexNext; stop if no more values
                        are available
                    (2) Test whether the corresponding testTable entry
                        does exist through a retrieval operation
                    (3) If the entry exists go back to (1), else
                    (4) Once 'ownership' is obtained, the testOwner and
                        test parameters can be setup, by creating a row
                        with the reserved testIndex and appropriate test
                        parameter settings.
                    (5) Then the test is initiated by setting the

                        testRowStatus to 'active'. The agent sets the
                        value of testResult to 'inProgress'.
                    On completion of the test, the agent sets testResult
                    and testCode in accordance with the test results and
                    sets the testResultTimeStamp.
          
                    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 entity 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 testIndex value assigned to an entity
                    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.
          
                    Managers are responsible for removing rows that are no
                    longer in use.
                    The table is flushed when the agent is reset."

                    activiated.
                    Manipulation of the test:
                    - When all test parameters (testTarget, testType,

                      value of testResult is reached.
                    - If the manager sets testRowStatus to 'active'
                      while the test is inProgress then this action
                      will not affect the ongoing test.
                    - Details of ongoing or completed tests are
                      reported in testResult and testCode.
                    - After test completion the test may be repeated
                      by first setting testRowStatus to 'notInService',
                      manipulating the test parameters as necessary, and
                      setting the testRowStatus to 'active' again.
                    - A manager may abort ongoing tests or remove
                      completed test information by setting the

          7.  Security Considerations
          
          There are a number of management objects defined in this MIB
          that have a MAX-ACCESS clause of read-write and/or read-
          create.  Such objects may be considered sensitive or
          vulnerable in some network environments. The support for SET
          operations in a non-secure environment without proper
          protection can have a negative effect on network operations.
          
          The managed objects in this MIB contain sensitive information
          since, collectively, they allow the invocation of tests on the
          managed device. These tests may have consequences such as
          configuration changes, service interruptions, etc. Security
          considerations for individual tests are discussed in the
          documents defining such tests.
          
          It is thus important to control even GET access to these
          objects and possibly to even encrypt the values of these
          object when sending them over the network via SNMP. Not all
          versions of SNMP provide features for such a secure
          environment.
          
          SNMPv1 by itself is not a secure environment. Even if the
          network itself is secure (for example by using IPSec), even
          then, there is no control as to who on the secure network is
          allowed to access and GET/SET (read/change/create/delete) the
          objects in this MIB.
          
          It is recommended that the implementers consider the security
          features as provided by the SNMPv3 framework. Specifically,
          the use of the User-based Security Model RFC 2574 [RFC2574]
          and the View-based Access Control Model RFC 2575 [RFC2575] is
          recommended.
          
          It is then a customer/user responsibility to ensure that the
          SNMP entity giving access to an instance of this MIB, is
          properly configured to give access to the objects only to
          those principals (users) that have legitimate rights to indeed
          GET or SET (change/create/delete) them.
