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
• oine stack-unit
• show diag
Hardware Commands
These commands display information from a hardware sub-component or ASIC.
The hardware commands are:
• clear hardware stack-unit
• show diag
• show hardware stack-unit
• show hardware system-ow
