Configuring connection types and port numbers

Ports are virtual connection points that software applications can use to send and receive data. Ports are distinguished by a specific port number. Different ports can be used to direct data to, or to receive data from, specific sources.

Software applications send and receive data over ports using protocols. A protocol is a software language, with its own rules and conventions, that software applications use to send, receive, and interpret data. Typical protocols include TCP, HTTPS, and HTTP.

The BlackBerry Enterprise Service 10 components use various ports to communicate with the BlackBerry Infrastructure, other external services, internal resources (for example, browsers), and with each other. The topics in this section list the default ports that the various components use. The tables indicate which ports you can change. If the table does not indicate that you can change the port, you must use the default port that is listed.

Depending on the size and complexity of your organization’s software environment, you may not need to change any of the port numbers. If your organization enforces certain security standards, restricts certain types of data that pass through the firewall, or has existing software that uses the ports that the components require, you may need to change some of the firewall settings or port settings.
