          INTERNET-DRAFT         System/Interface Test MIB               June 1997
          
          
          Abstract
          
             This memo defines an experimental 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 replaces the objects
             originally defined in the ifTestGroup of RFC1573, the IF-MIB [6],
             which have been deprecated.
          
             This memo specifies a MIB module in a manner that is both compliant
             to the SNMPv2 SMI, and semantically identical to the peer SNMPv1
             definitions.
          
             This memo does not specify a standard for the Internet community.
          
          
          1.  The SNMP Network Management Framework
          
             The SNMP Network Management Framework presently consists of three
             major components.  They are:
          
             o    the SMI, described in RFC 1902 [1] - the mechanisms used for
                  describing and naming objects for the purpose of management.
          
             o    the MIB-II, STD 17, RFC 1213 [2] - the core set of managed
                  objects for the Internet suite of protocols.
          
             o    the protocol, RFC 1157 [3] and/or RFC 1905 [4], - the protocol
                  for accessing managed objects.
          
             The Framework permits new objects to be defined for the purpose of
             experimentation and evaluation.
          
          
          
          1.1.  Object Definitions
          
             Managed objects are accessed via a virtual information store, termed
             the Management Information Base or MIB.  Objects in the MIB are
             defined using the subset of Abstract Syntax Notation One (ASN.1)
             defined in the SMI.  In particular, each object type is named by an
             OBJECT IDENTIFIER, an administratively assigned name.  The object
             type together with an object instance serves to uniquely identify a
             specific instantiation of the object.  For human convenience, we
             often use a textual string, termed the descriptor, to also refer to
             the object type.

          2.  Experience with the Interfaces Test Group
          
             The ifTestGroup of objects defined in RFC1573 has not been used
             widely. Some cited problems were:
          
          
             o    Few standard tests had been defined to date.
          
             o    Some well known tests had already been written on a media-
                  specific basis, e.g., DS1 loopback.
          
             o    The ifTestGroup allowed for interface testing only.
          
             o    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.
          
          
          3.  Requirements for a Generic Test MIB
          
             This section describes the requirements that have been identified for
             a generic test MIB.
          
          3.1.  Test Identification
          
             The system defined in RFC1573 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.

          3.2.  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 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.

          3.3.  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.
          
             Note that searching criteria on the log relate to this choice as
             well.
          
             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).
          
             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.
          
          
          3.4.  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.

          INTERNET-DRAFT         System/Interface Test MIB               June 1997
          
          
             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:
          
             o    What is the result of test (testIndex)?
          
             o    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.
          
          
          3.5.  Determining Agent Test Capabilities
          
             A testCapabilitiesTable has been defined to list the tests that can
             be performed through this agent.

                                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

                                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.  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.
          
                               Once ownership is obtained, the test parameters can be
                               setup, and then the test is initiated by activating the
                               row through testRowStatus. 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 testCompletionTime.
          
                               If testRowStatus is not set to active within an
                               abnormally long period
                               of time after ownership is obtained, the agent should
                               time-out the manager, and reset the value of the
                               testRowStatus object back to 'destroy'.  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 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

                               due to resource constraints, make available at least the
                               minimum amount of information after that test
