White Papers

Parameters
number Enter the stack-unit number. The range is from 0 to 5.
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.
no-reboot Enter the keyword no-reboot to avoid automatic rebooting of the chassis after
completion of diagnostic execution. Generally, this option is never used because if
you run the diagnostic once again without rebooting the chassis, it may cause an
issue with the diagnostic results..
terminate Enter the keyword terminate to stop the execution of the level diag that is
already started using the diag stack-unit command. Once this CLI is issued, syslogs
indicating the termination of the diag test is displayed. The diag results for the
executed tests are stored in the flash directory (TestReport-SU-X.txt).
interactive Enter the keyword interactive to run some individual diag tests such
as POWERLEDTEST, STATUSLEDTEST and so on. The help option under the
interactive command displays the list of tests that can be run.
