Debugging and Diagnostics
The basic debugging and diagnostic commands are supported by the Dell Networking operating software (FTOS) on the
Z-Series 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, 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.
diag stack-unit
Run offline diagnostics on a stack unit.

verbose testname
Parameters
number Enter the stack-unit number. The range is from 0 to 7.
alllevels Enter the keyword alllevels to run the complete set of offline
diagnostic tests.
level0 Enter the keyword level0 to run Level 0 diagnostics. Level 0
diagnostics check for the presence of various components and
perform essential path verifications. In addition, they verify the
identification registers of the components on the board.
level1 Enter the keyword Level1 to run Level 1 diagnostics. Level 1
