S-Series Debugging and Diagnostics
The basic debugging and diagnostic commands are supported by FTOS on all Dell
Force10 platforms, as indicated by the characters that appear under each of the
command headings:
e E-Series, c C-Series, s S-Series (S25/S50), , or
.
This chapter contains three 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
console.
In other words, you cannot run diagnostics on a unit to which you are connected
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.
The offline diagnostics commands are:
• diag stack-unit
• offline stack-unit
• online stack-unit
