Hi all,

I would like to know what problem usually happen to the router (7600
SRC3, SUP720-3B, X6748-DFC) which most of the time failing the
TestmacNotification diagnostic test.

Router# sh diagnostic result module 3 detail
12) TestMacNotification -------------> .

          Error code ------------------> 1 (DIAG_FAILURE)
          Total run count -------------> 13
          Last test execution time ----> Aug 10 2009 11:39:09
          First test failure time -----> Aug 10 2009 11:20:28
          Last test failure time ------> Aug 10 2009 11:39:09
          Last test pass time ---------> Aug 10 2009 11:31:58
          Total failure count ---------> 7
          Consecutive failure count ---> 3

And sometimes the linecard is failing the test consecutively and make
the linecard reset.

Please help me to troubleshoot this problem.
