What is necessary to provide when adding an endpoint into ISE?

When adding an endpoint into Identity Services Engine (ISE), it is necessary to provide the MAC address of the device. The MAC address is a unique identifier assigned to network interfaces for communications on the physical network segment. In ISE, the MAC address is critical for accurately identifying the endpoint and applying appropriate policies, authentication, and authorization processes.

Providing the MAC address ensures that the endpoint is correctly registered in the ISE database, allowing for effective monitoring and management of network access. This identification is essential for various functions, such as network access control, profiling, and endpoint visibility.

While other identifiers, such as the serial number, IP address, or network name, can be useful in different contexts or systems, the MAC address is specifically fundamental to the endpoint registration process within ISE. It serves as the primary means of uniquely identifying the device on the network.
