The columns in the Port Utilization tables in this document describe the following:

• Port. A numeric identifier the Internet transport protocol uses to distinguish among multiple, simultaneous connections to a single
destination host.
• Remote Source Port. An identifier—usually dynamic—for the port the remote application or service uses to connect to the local
destination port.
• Destination Port. An identifier for the TCP or UDP port that the local service or application is listening on, along with the IP address for
incoming connection requests when acting as a server.
• Source Port. An identifier—usually dynamic—for the port the local application or service uses to connect to the remote device’s
destination port.
• Remote Device Destination Port. The identifier for the TCP or UDP port that the remote device’s service or application is listening on,
along with the IP address for incoming connection requests when acting as the server.
• Remote Device. The remote application or device making a connection to the server or service specified by the protocol.
