www.dell.com | support.dell.com 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] Parameters number alllevels level0 level1 level2 Enter the stack-unit number. Unit ID range: S55: 0-11 all other S-Series: 0-7 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. Enter the keyword Level1 to run Level 1 diagnostics. Level 1 diagnostics is a smaller set of diagnostic tests with support for automatic partitioning. They perform status/self test for all the components on the board and test their registers for appropriate values. In addition, they perform extensive tests on memory devices (e.g., SDRAM, flash, NVRAM, EEPROM, and CPLD) wherever possible. There are no tests on 10G links. At this level, stack ports are shut down automatically. Enter the keyword level2 to run Level 2 diagnostics. Level 2 diagnostics is a full set of diagnostic tests with no support for automatic partitioning. Level 2 diagnostics are used primarily for on-board loopback tests and more extensive component diagnostics. Various components on the board are put into loop back mode, and test packets are transmitted through those components. These diagnostics also perform snake tests using VLAN configurations. You must physically remove the unit from the stack to test 10G links. Defaults None 1078 | S-Series Debugging and Diagnostics
