Oine Diagnostic Commands
The oine diagnostics test suite is useful for isolating faults and debugging hardware. While tests are running, the Dell Networking OS
results are saved as a text le (TestReport-SU-X.txt) in the ash directory. The
show file command is available only on Master and
Standby.
Important Points to Remember
Oine diagnostics can only be run when the unit is oine.
Oine diagnostics cannot be run in Stacking mode.
You can only run oine diagnostics on a unit to which you are connected via the console. In other words, you cannot run diagnostics on
a unit to which you are connected via a stacking link.
Diagnostic results are stored in a le (TestReport-SU-X.txt) in the ash directory. To review the results, use the show file command,
which prints the results to the screen.
Diagnostics only test connectivity, not the entire data path.
The oine diagnostics commands are:
diag stack-unit
