Which method is commonly used to configure network devices for troubleshooting?

The command line interface (CLI) is a widely used method for configuring network devices, particularly when it comes to troubleshooting. The CLI allows administrators to input specific commands to view, configure, and manage network devices efficiently. This direct interaction with the device's operating system provides a level of granularity and control that can be particularly useful during troubleshooting.

Using CLI, network professionals can quickly navigate through configuration settings, check status, perform diagnostics, and make real-time adjustments. Commands may include diagnostic tools like ping and traceroute, as well as configuration commands to change settings or apply updates, which can help identify and resolve issues rapidly.

While web interfaces can also be used for configuration and management, they might not offer the same depth of access or speed when dealing with issues that require immediate attention. Console cables are typically used to establish a direct physical connection to a device’s CLI for initial setup or recovery purposes, but they are not a method of configuration in the same sense. Network management software can help monitor and manage multiple devices, but it may not provide the immediate and detailed access necessary for direct troubleshooting of individual devices.

Thus, using the command line interface stands out as the preferred method for quickly and effectively diagnosing and resolving network issues.
