66 S-Series 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, 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 diag stack-unit s Run offline diagnostics on a stack unit. Syntax diag stack-unit number [alllevels | level0 | level1 | level2] verbose testname Parameters number alllevels level0 Enter the stack-unit number. Range: 0 to 7 Enter the keyword alllevels to run the complete set of offline diagnostic tests. 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.
