12 Debugging and Diagnostics Use the debugging and diagnostics commands described in this chapter to troubleshoot switch operation. This chapter contains the following sections: • Offline Diagnostic Commands • Hardware Commands Topics: • Offline Diagnostic Commands • Hardware Commands Offline Diagnostic Commands Use the offline diagnostics test suite to isolate faults and debug switch hardware. While tests are running, the system results are saved as a text file in the flash directory: TestReport-N.txt , where N is 0,1, or 2 for the line-card processor (LP) and 0 for the Control processor (CP) and Route Processor (RP). To display the system results in this text file, use the show file command. 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. The Dell Networking OS does not write them to memory. • Diagnostics only test connectivity, not the entire data path. diag Run offline diagnostics on all CPUs or on a specified CPU in the switch. C9000 Series Syntax Parameters diag {cp-unit | linecard | pe [pe-id stack-unit unit-number] | system} } [alllevels | level0 | level1 | level2] [interactive] [testname name][terminate] cp unit-id linecard slot-id Enter the cp unit-id parameters to run offline diagnostic tests only on the Control Processor CPU. The Control Processor CPU ID is 0. Enter the linecard unit-id parameters to run offline diagnostic tests only on a specified line card. The linecard slot-id range is from 0 to 11. Each line-card CPU processes packets on the corresponding switch line card; for example, line-card CPU 1 processes packets on line card 1. Debugging and Diagnostics 626
