    This IBM Redpaper provides various tips and techniques for managing TCP/IP with IBM i5/OS:

    - Various recommendations that might improve your network configuration and enable you to obtain optimal performance in a TCP/IP network.

    - Information about the different ways that TCP/IP can be started and ended, including potential problems that might occur if starting TCP/IP is not carefully planned.

    - Discussion about why it is important for a TCP/IP application to check the status of TCP/IP in a proper way. Includes an example of a program that checks TCP/IP status.

    - Procedure for assigning an alias to a TCP/IP interface that can be used in place of an IP address in programs. Information is also provided about a new feature called the preferred interface list to assist with handling adapter failures.

    - Notes about using exit programs and what you can do with the exit points that are defined for IBM-supplied TCP/IP applications.
