This chapter contains three sections:

• Buffer Tuning Commands
• Hardware Commands
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.
Important Points to Remember
• Offline diagnostics can only be run when the unit is offline.
• 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.
The offline diagnostics commands are:
• diag stack-unit
• offline stack-unit
• online stack-unit
