To display error messages using Telnet:
1.
From the prompt, enter the
errShow
command.
2.
To scroll through the error list, type CR.
3.
Scroll through error log (if no errors are encountered, the command returns
“
No
Error
”
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 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
Note:
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
after running the
portStatsShow
command again.
