39 Debugging and Diagnostics 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, the Dell Force10 operating software (FTOS) results are saved as a text file (TestReport-SU-X.txt) in the flash directory. The 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 via a stacking link. • Diagnostic results are stored in a file (TestReport-SU-X.txt) in the flash directory. To review the results, use the show file command, which prints the results to the screen. • Diagnostics only test connectivity, not the entire data path. The offline diagnostics commands are: • diag stack-unit • offline stack-unit • online stack-unit diag stack-unit Run offline diagnostics on a stack unit. Syntax Parameters diag stack-unit number [alllevels | level0 | level1 | level2] verbose no-reboot number alllevels Enter the stack-unit number. Range: 0 to 5 Enter the keyword alllevels to run the complete set of offline diagnostic tests. Debugging and Diagnostics | 675
