application coredump is aborted. Dell EMC Networking OS completes the coredump process and wait until the upload is complete before rebooting the system. Offline Diagnostic Commands The offline diagnostics test suite is useful for isolating faults and debugging hardware. While tests are running, Dell EMC Networking OS 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. • The system stores the diagnostic results in the flash directory (TestReport-SU-X.txt). The system displays the following message after the diagnostic test is over. 05:37:17 : Diagnostic test results are stored on file: flash:/TestReport-SU-1.txt 05:37:22: %S3048-ON:1 %DIAGAGT-6-DA_DIAG_DONE: Diags finished on stack-unit 1 • Diagnostics only test connectivity, not the entire data path. diag stack-unit Run offline diagnostics on a stack unit. Syntax diag stack-unit number [alllevels | level0 | level1 | level2] verbose [testname | no-reboot] Parameters number Enter the stack-unit id. alllevels level0 level1 level2 verbose testname no-reboot 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 (for example, 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 are 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 Loopback mode and test packets are transmitted through those components. These diagnostics also perform snake tests using VLAN configurations. To test 10G links, physically remove the unit from the stack. Enter the keyword verbose to run the diagnostic in Verbose mode. Verbose mode gives more information in the output than Standard mode. Enter the keyword testname to run a specific test case. Enclose the test case name in double quotes (" "). For example: diag stack-unit 1 level1 testname "first". You can use this option only for interactive tests. Enter the keyword no-reboot to prevent the system from rebooting after the test. To bring the stack unit to online state, use the online stack-unit stack-unitnumber command. 464 Debugging and Diagnostics
