4.3.  802.3 Tests


      --  802.3 Tests

      -- The ifExtnsTestTable defined in RFC 1229 provides a common
      -- means for a manager to test any interface corresponding to





      -- a value of ifIndex.

      -- At this time, one well known test (testFullDuplexLoopBack) is
      -- defined in RFC 1229.  For ethernet-like interfaces, this test
      -- configures the MAC chip and executes an internal loopback
      -- test of memory and the MAC chip logic.  This loopback test can
      -- only be executed if the interface is offline.  Once the test
      -- has completed, the MAC chip should be reinitialized for network
      -- operation, but it should remain offline.

      -- If an error occurs during a test, the object ifExtnsTestResult
      -- (defined in RFC 1229) will be set to failed(7).  The following
      -- two OBJECT IDENTIFIERs may be used to provided more
      -- information as values for the object ifExtnsTestCode in
      -- RFC 1229:

          dot3Errors             OBJECT IDENTIFIER ::= { dot3 7 }

                               -- couldn't initialize MAC chip for test
          dot3ErrorInitError     OBJECT IDENTIFIER ::= { dot3Errors 1 }

                                -- expected data not received (or not
                                -- received correctly) in loopback test
          dot3ErrorLoopbackError OBJECT IDENTIFIER ::= { dot3Errors 2 }

       -- Tests
        --  TDR Test

       -- Another test, specific to ethernet-like interfaces with the
       -- exception of 10BaseT and 10BaseF, is Time-domain Reflectometry
           (TDR).
       -- The TDR value may be useful in determining the approximate
           distance
       -- to a cable fault.  It is advisable to repeat this test to
           check for
       -- a consistent resulting TDR value, to verify that there is a
          fault.

          dot3Tests   OBJECT IDENTIFIER ::= { dot3 6 }
          dot3TestTdr OBJECT IDENTIFIER ::= { dot3Tests 1 }

       -- A TDR test returns as its result the time interval, measured
       -- in 10 MHz ticks or 100 nsec units, between the start of
       -- TDR test transmission and the subsequent detection of a
       -- collision or deassertion of carrier.  On successful completion
       -- of a TDR test, the appropriate instance of ifExtnsTestResult
       -- contains the OBJECT IDENTIFIER of the MIB object which
       -- contains the value of this time interval.
