Debugging and Diagnostics
Enter the keyword Level1 to display only the Level 1
diagnostic tests. 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, ports are shut down automatically.
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 transmitted through those components. These diagnostics also
perform snake tests using VLAN configurations.
