Command Line Reference Guide

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..
