Reference Guide

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. You must physically
remove the unit from the stack to test 10G links.
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 level2 to run a specific test case.
Enclose the test case name in double quotes (“ “). For
example: diag stack-unit 1 level1 testname
“first”.
