Administrator Guide

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.
