TCP/IP is at the core of the communication for the z/OS mainframe, both for communication between the z/OS images and processor complexes, and for traffic to and from the mainframe. Monitoring TCP/IP is important for:
- Performance – Is the workload properly balanced across the available interfaces?
- Network health – Are there errors as a result of physical or logical configuration issues?
- Security – Are encrypted connections always being used as expected?
Understand Traffic Patterns | Protect System Availability
IntelliMagic Vision for z/OS provides insight in the use of the physical interfaces, including the OSA channels and the new HiperSockets that are used for communication between LPARs. The traffic can be analyzed from different perspectives:
- address space (socket)
- port number (protocol)
- physical interface
The reporting also covers system-wide health metrics, like the availability of sufficient ephemeral (dynamic) ports in the pools for UDP and TCP/IP address spaces, or unexpected network errors. Just like for other aspects of the z/OS infrastructure, dashboards are used to summarize the results of the network health checks. You will no longer be surprised by a lack of ephemeral ports capacity or fabric issues.
Customer Experience from one of our early users said
The TCP/IP reports provide a lot of useful information and in some instances we now have the ability to better understand our interfaces and their usage, which is something we have never had in the past.”

Intelligent Analysis of TCP/IP zERT Summary Data
TCP/IP’s z/OS Encryption Readiness Technology (zERT) feature provides a single source of data to determine which traffic to and from your site is cryptographically protected by protocols like TLS, SSH, and IPSec, and which is not protected.
How to Use IBM’s zERT to Identify Unencrypted Connections
The primary use of the zERT data is likely to be the identification and remediation of unencrypted connections.
