What is the primary method to add an endpoint into ISE?

Accessing the system via Internet Explorer is the primary method to add an endpoint into Identity Services Engine (ISE). This approach allows users to engage with the ISE's web-based interface, which is designed for managing endpoints, policies, and configurations. The user-friendly graphical interface facilitates the input of endpoint details, making it efficient and straightforward.

Using the web interface through a browser like Internet Explorer leverages the full capabilities of the system, including advanced features and functionalities specifically designed for endpoint management. This method ensures that data entry is streamlined and provides real-time feedback, which aids in reducing errors during the configuration process.

Other methods, such as securing a connection via secure shell or using FTP, are typically more suited for different administrative tasks, like system maintenance or file transfers, rather than directly adding endpoints. Therefore, the web interface through Internet Explorer is the most direct and effective way to manage endpoint configurations within ISE.
