Diagnostic Error Message Formats
If any port fails during a diagnostic test, it is marked BAD in the status
display.
To retest a port which has been marked BAD, clear the port and set to
OK using the
diagClearError (port#) command. This command
clears the port status only and does not clear the logs or change the
port’s condition. The
diagClearError (port#) command should
only be used during diagnostic procedures to reset a bad port for
retest.
Some messages contain the following abbreviations:
• sb = Should Be
• er = Bits in error
If you run the portStatsShow or the diagShow command prior to running
a test, errors may appear as a result of the normal synchronization process.
These errors should be addressed if the number of errors found increases
when running the portStatsShow command again.
Running any of the tests discussed in “Front Panel Test Menu” clears the
accumulated errors before the test is run.
