TCP/IP tools and diagnostic aids

Networking on z/OS

In addition to abnormal end dumps, TCP/IP has various tools and diagnostic aids for problem source identification.

Note: TCP/IP utilizes VTAM for both memory (Communications Storage Manager, CSM) services and for communications I/O. Consequently, when analyzing TCP/IP problems, VTAM diagnostic data may also be required.
  • Tracing TCP/IP components
    By utilizing the z/OS component trace facility, you can store trace data efficiently (with low system impact) into data sets. After tracing of a failure is complete, IPCS can be used to format and view the data.
  • Diagnostic TCP/IP commands
    Commands used to display TCP/IP and network information include NETSTAT, PING, and TRACERTE.
