What is siteFallbackSoftwareVersion?

This read-only OID displays the firmware version (up to 15 characters) that the switch will automatically boot into if the current software becomes corrupted or fails. Engineers check this value to verify that a safe fallback version is configured and available. For example, if it shows '4.2.1', the switch will revert to that stable version automatically, allowing continued operation while repairs are made.
