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.
