Enter the keyword level2 to display only the Level 2 diagnostic
tests. 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.

Level 0 — 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.
Level 1 — A smaller set of diagnostic tests. Level 1 diagnostics 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, or EEPROM) wherever possible.
Level 2 — The full set of diagnostic tests. 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
