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”
.
