Reference Guide
Version Description
7.7.1.0 Introduced on the S-Series.
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.
