Theon-box web interface for configurationis a key feature of the Cisco Catalyst 2960-L Series Switches, enabling rapid deployment in small branch or office environments. According to Cisco’s official documentation, the 2960-L series is equipped with an intuitive, built-in web-based GUI (also referred to as the “Cisco Configuration Professional for Catalyst” or “web UI”) that allows users to perform basic setup and management without the need for CLI expertise or external management platforms.

From the Cisco Catalyst 2960-L Series Switches Data Sheet:

“An on-box web interface helps customers configure and manage their network quickly and easily, allowing them to get a small branch or office network up and running in minutes. This browser-based device manager reduces the need for CLI skills and speeds time to deployment.”

Other options, such as full CLI support, do exist, but the question specifically refers to enabling rapid, simplified deployment—which is exactly the use case for the on-box web interface. Stackwise-160 is not available on 2960-L, and support for Cisco DNA Center is limited on this series.
