Dell Command Line Reference Guide for the S4048–ON System 9.14.2.8

diag stack-unit number [alllevels | level0 | level1 | level2] verbose [testname | no-reboot]

number

Enter the stack-unit id.

alllevels

Enter the keyword alllevels to run the complete set of offline diagnostic tests.

level0

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.

level1

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.

level2

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.

verbose

Enter the keyword verbose to run the diagnostic in Verbose mode. Verbose mode gives more information in the output than Standard mode.

testname

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.

no-reboot

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-unit-number command.
