Debugging And Diagnostics; Offline Diagnostic Commands; Diag Stack-Unit - Dell Force10 S4810P Reference Manual

Debugging and Diagnostics

The basic debugging and diagnostic commands are supported by the Dell Force10 operating software (FTOS) on the C-
Series, E-Series, S-Series, S4810, or Z-9000 platforms as indicated.
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, FTOS
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. FTOS does not write them to memory.
• Diagnostics only test connectivity, not the entire data path.
