Debugging And Diagnostics; Offline Diagnostic Commands; Diag Stack-Unit - Dell S4810 Reference Manual

Debugging and Diagnostics

The basic debugging and diagnostic commands are supported by the Dell Networking Operating System
(OS) on the S4810 platform.
This chapter contains the following sections:
•

Offline Diagnostic Commands

• 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, Dell 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.
• Diagnostic results are printed to the screen. Dell Networking OS does not write them to memory.
• Diagnostics only test connectivity, not the entire data path.
