Abstract

The IBM z/OS Communications Server Network Utility Assistant tool is an unofficial TSO/ISPF front-end to the z/OS Communications Server TSO NETSTAT line-mode command.

Download Description

NOTE: This is not officially supported code from z/OS CS development. It is not part of normal z/OS CS development efforts. It is made available on an as-is basis only. There is no guarantee that it works in all installations. There is no commitment to make this code officially part of z/OS CS.

There are no plans to include it in future releases. A RFE (Request for Enhancement) should be opened to include this in a future release of the product.

You can use the following link to submit an RFE:

The brand, product family, product and component are Websphere, Enterprise Networking, z/OS Communications Server, and TCP/IP respectively.

Background 

The z/OS Communications Server NETSTAT command is a line-mode command that is available in TSO, the UNIX shell, and as a z/OS console command. In all environments, NETSTAT is invoked with a set of options that can be grouped in three ways:

  • The NETSTAT report name

    NETSTAT in z/OS V1R12 supports 29 different reports.

    General and report-specific modifiers

    Most reports have report-specific modifiers that are used to modify the type of information the NETSTAT report returns. The highest number of report-specific modifiers is seven on the ROUTE report. Some of the modifiers can be used together, and others are mutually exclusive.

    Report filters

    Report filters are used to reduce the amount of data that is returned from NETSTAT. z/OS Communications Server provides 13 different types of filters. Each report that supports filters supports one or more of these filter types. Multiple filter types cannot be mixed on a single NETSTAT invocation, but most of the filter types support up to six filter values (of the same type).


As the number of NETSTAT options has increased over the years, the use of the NETSTAT command as a line-mode command has become complicated. Users generally tend to remember a few reports and combinations of modifiers and filters and limit their use of NETSTAT to these few selected NETSTAT commands.

The Network Utility Assistant

This tool is a TSO/ISPF application that wraps around the z/OS Communications Server NETSTAT TSO command, providing a full-screen TSO-based interface to the NETSTAT command. It operates only in the TSO environment, not in NetView and not on the console.
