CLI Guide

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.
Defaults None
