Purpose of this information
This information presents the meaning and coding syntax of Virtual Telecommunications Access Method (VTAM®) resource definition statements and operands, NCP resource definition statements and operands that affect VTAM, start options, and macroinstructions and operands for user-defined tables. The information includes descriptions of support for both IPv4 and IPv6 networking protocols. Unless explicitly noted, descriptions of IP protocol support concern IPv4. IPv6 support is qualified within the text.
To plan for the tasks of installing VTAM and defining resources to it, see z/OS Communications Server: New Function Summary.
When you are ready to install VTAM and define resources to it, you can find the broader, more conceptual information about installation and definition in the z/OS Communications Server: SNA Network Implementation Guide.
This information contains the specifics of resource definition.
Who should read this information:
This document is intended to help system programmers define resources to VTAM.
How this information is organized:
This topic describes the symbols and coding conventions used for the definition statements and macroinstructions described in this information. Descriptions of the sift-down effect and each type of major node are also included.
This topic describes the VTAM definition statements used to define major nodes. Descriptions of NCP definition statements and their operands are given only when they affect VTAM.
This topic describes the VTAM definition statements used, in general, to define routes and to dynamically reconfigure and dynamically change resources.
This topic describes VTAM start options and how you can code them to set various conditions that are to exist while VTAM is running.
This topic describes how to create or modify the associated LU table, Class-of-Service table, CMIP services directory definition file, interpret table, logon mode table, message-flooding prevention table, model name table, and unformatted system services (USS) table. It also describes how to code the session awareness (SAW) data filter.
This appendix contains listings of the IBM-supplied default tables.
This appendix contains examples of how to code USS tables to convert commands.
This appendix summarizes the results of using the VTAMTOPO filtering option for reporting a switched PU under an NCP.
This appendix lists documents that provide architectural specifications for the SNA Protocol.
This appendix lists information APARs for IP and SNA documents.
This appendix describes accessibility features to help users with physical disabilities.
Contains notices and trademarks used in this document.
Contains descriptions of the documents in the z/OS® Communications Server library.
How to use this information:
You can use this document as a reference for specific operator commands and as background reading to help understand how to operate VTAM.
To use this document, you should be familiar with the basic concepts of telecommunication, SNA, and VTAM.
