www.dell.com | support.dell.com Offline Diagnostics The offline diagnostics test suite is useful for isolating faults and debugging hardware.The 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, access, and read/write tests 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) wherever possible. • Level 2—The full set of diagnostic tests. Level 2 diagnostics are used primarily for on-board MAC level, Physical level, and external 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 virtual local area network (VLAN) configurations. Note: Diagnostic is not allowed in Stacking mode, including member stacking. Avoid stacking before executing the diagnostic tests in the chassis. Important Points to Remember • You can only perform offline diagnostics on an offline standalone unit. You cannot perform diagnostics if the ports are configured in a stacking group. Remove the port(s) from the stacking group before executing the diagnostic test. • Diagnostics only test connectivity, not the entire data path. • Diagnostic results are stored on the flash of the unit on which you performed the diagnostics. • When offline diagnostics are complete, the unit or stack member reboots automatically. Running Offline Diagnostics To run offline diagnostics, follow these steps: 1. Place the unit in the offline state using the offline stack-unit command from EXEC Privilege mode (Figure 22-3). The system reboots when the off-line diagnostics complete. This is an automatic process. A warning message appears when you implement the offline stack-unit command. Warning - Diagnostic execution will cause stack-unit to reboot after completion of diags. Proceed with Offline-Diags [confirm yes/no]:y 246 | Debugging and Diagnostics

Use the show system brief command from EXEC Privilege mode to confirm offline status (Figure 22-4). Figure 22-4.

Each trace message provides the date, time, and name of the FTOS process. All messages are stored in a ring buffer and can be saved to a file either manually or automatically upon failover. Auto Save on Crash or Rollover Exception information on Master or Standby units is stored in the flash:/TRACE_LOG_DIR directory. This directory contains files that save trace information when there has been a task crash or timeout. On a Master unit, you can reach the TRACE_LOG_DIR files by file transfer protocol (FTP) or by using the show file command from the flash://TRACE_LOG_DIR directory. On a Standby unit, you can reach the TRACE_LOG_DIR files only by using the show file command from the flash://TRACE_LOG_DIR directory. Note: Non-management Member units do not support this functionality. Debugging and Diagnostics | 247
