The only way to get access to all of the possible diagnostic CLI commands is...

Comprehensive and Detailed In-Depth Explanation:Infoblox NIOS provides a Command Line Interface (CLI) for diagnostics, accessible via multiple methods, not solely the serial port:

Serial Console:Connecting a serial cable (9600 baud) to the appliance’s serial port grants CLI access, useful for physical troubleshooting or when network access is down. It provides full diagnostic commands (e.g., "show process," "set debug").

SSH:Remote access via SSH (default port 22) to the appliance’s management IP offers the same CLI, assuming network connectivity and credentials are available. This is equally comprehensive.

Key Point:Both methods provide access to all diagnostic commands (e.g., "show log," "reset database"), debunking the "only way" claim. The serial port is just one option, often used in failure scenarios (e.g., network outage), but SSH is more common day-to-day.

INE Context:The course covers CLI troubleshooting, emphasizing both serial and SSH access for Grid diagnostics, making this a practical distinction.
