What is the function of the Command Line Interface (CLI) in switch management?

The function of the Command Line Interface (CLI) in switch management is centered around providing a text-based command management system for network devices. The CLI allows network administrators to configure, manage, and troubleshoot switches through direct command input. This method of interaction is efficient for performing a wide range of tasks such as setting up VLANs, managing interfaces, and applying access controls on the device, all done through typed commands rather than a graphical interface.

Utilizing a CLI can offer more granular control compared to graphical user interfaces, which are generally more user-friendly but may not expose all possible functions or configurations. The CLI is also typically more powerful for experienced users who are comfortable with command syntax, allowing for more complex and rapid configurations, especially in large-scale environments where automation may be necessary.

The other options do not accurately capture the primary function of the CLI in switch management. While a graphical user interface offers a different approach to management, it is not what the CLI is designed for. Real-time monitoring of network traffic generally requires different tools or interfaces that are not specific to the CLI. Similarly, while establishing connections with remote devices can involve CLI commands, this is not the primary purpose of a CLI but rather one of the functionalities it supports within broader network management.
