Offline Diagnostic Commands

The offline diagnostics test suite is useful for isolating faults and debugging hardware. While tests are
running, the Dell Force10 operating software (FTOS) results are saved as a text file
(TestReport-SU-X.txt) in the flash directory. The show file command is available only on Master and
Standby.

Offline Diagnostic Commands
Hardware Commands
Offline diagnostics can only be run when the unit is offline.
Offline diagnostics cannot be run in Stacking mode.
You can only run offline 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 file (TestReport-SU-X.txt) in the flash 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.
