Debugging and Diagnostics
The basic debugging and diagnostic commands are supported by the Dell Networking OS on the S5000
switch.
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.
