In the access tracker of ClearPass, after a customer successfully connects to a guest network through a captive portal, the OUTPUT tab should show a role indicating that the user is authenticated, such as "Guest authenticated." This role confirms that the user has passed the authentication process and has been granted access.

ICMP (Internet Control Message Protocol) is used by network devices to send error and operational information related to IP communications. It is used to send messages like
"destination unreachable" or "time exceeded" when there are issues in IP communication

A /30 subnet contains 4 addresses: the network address, two usable host addresses, and the broadcast address.
For the 10.0.1.0/30 subnet:
Network address: 10.0.1.0
Usable hosts: 10.0.1.1 and 10.0.1.2
Broadcast address: 10.0.1.3

A UXI (User Experience Insight) is a device that simulates user behavior and tests network performance from the user perspective. It can check different applications, such as HTTP, VOIP, or Office 365, and measure metrics such as latency, jitter, packet loss, and throughput.

The Address Resolution Protocol (ARP) is used to map layer-3 IP addresses to layer-2 MAC addresses. When a device on a network wants to communicate with another device, it uses ARP to find the MAC address that corresponds to the IP address it wishes to communicate with, allowing it to construct a frame for the local network.
