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, ports are shut
down automatically.
level2 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.
Defaults Display the complete set of offline diagnostic tests available at all levels.

Usage
Information
Offline diagnostics tests are grouped into three levels:
● 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 transmitted through those components. These diagnostics
also perform snake tests using VLAN configurations.
