Offline Diagnostic Commands

The offline diagnostics test suite is useful for isolating faults and debugging hardware. While tests are running, Dell EMC Networking OS results are saved as a text file (TestReport-SU-X.txt) in the flash directory. This 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 to via a stacking link.
  • The system stores the diagnostic results in the flash directory (TestReport-SU-X.txt). The system displays the following message after the diagnostic test is over.
    05:37:17 : Diagnostic test results are stored on file: flash:/TestReport-SU-1.txt
    05:37:22: %S3048-ON:1 %DIAGAGT-6-DA_DIAG_DONE: Diags finished on stack-unit 1
  • Diagnostics only test connectivity, not the entire data path.
