TCP/IP

Transmission Control Protocol/Internet Protocol (TCP/IP) is a set of industry-standard protocols and applications that enable you to share data and computing resources with other computers, both IBM and non-IBM. By using TCP/IP commands at your workstation, you can perform tasks and communicate easily with a variety of other systems and workstations. z/OS Communications Server enables the user to interactively run TCP/IP applications (TCP/IP commands) from both the Time Sharing Option (TSO) and the z/OS shell.

For z/OS 2.4 and later, automatically collect data from SMF Type 1154 Subtype 1 to check whether all TCP/IP stacks have AT-TLS enabled, check whether IP packet forwarding is disabled on all TCP/IP stacks, check whether TCP/IP stacks are configured to audit important events, and more.

Note: Compliance data collection for Comm Server: TCP/IP requires z/OS 2.4 or later and PTFs for PH37372
