Diagnostics

Diagnostics

Diagnostics include hardware and software components, and it runs in two modes: ROM and Firmware. The transition between the two modes is automatically controlled by SonicSetup, and is transparent to the administrator.

Diagnostics include (component and mode noted in parenthesis):

•Interface Test – Demonstrates operability of the LAN interface by means of discovery. (Hardware, Implicit)

•Validate ROM – Verifies that the ROM checksum stored in flash matches the calculated check- sum. (Hardware, ROM)

•Firmware Flash Region Test – Performs sector verification on the area in flash memory in which the firmware is stored. Only run in the event of firmware corruption. (Hardware, ROM)

•Wireless Radio Test – Tests the wireless radio component of SonicWALL appliances with an inte- grated 802.11 radio. (Hardware, ROM)

•Modem Test – Tests the modem component of SonicWALL appliances with an integrated modem. (Hardware, ROM)

•Firmware Validation – Verifies the state of firmware by validating the header and performing a CRC check on the data. If the validation fails, the Firmware Flash Region test is flagged to run. (Software, ROM)

•Bootlog Analysis – While the firmware starts, the startup messages (typically displayed on the console) are written to a protected region of memory. The SonicWALL security appliance is allotted a certain time to complete the boot process which, if exceeded, triggers a reboot. If the boot process fails again, the device reboots into SafeMode. From SafeMode, SonicSetup retrieves the bootlog and will determine the point of failure. (Software, Firmware).
