Abstract for SNA Network Implementation Guide
- Install VTAM
- Define network resources to VTAM
- Replace user tables and exit routines
- Tune VTAM for a specific environment
It also provides guidance for using VTAM resource definition statements and macroinstructions. Use this document when installing, upgrading, or otherwise changing a VTAM network. The information in this document supports both IPv6 and IPv4. Unless explicitly noted, information describes IPv4 networking protocol. IPv6 support is qualified within the text.
Conventions and terminology that are used in this information
- When describing how to use the command in a TSO environment, the command is presented in uppercase (for example, NETSTAT).
- When describing how to use the command in a z/OS UNIX environment, the command is presented in bold lowercase (for example, netstat).
- When referring to the command in a general way in text, the command is presented with an initial capital letter (for example, Netstat).
All the exit routines described in this information are installation-wide exit routines. The installation-wide exit routines also called installation-wide exits, exit routines, and exits throughout this information.
The TPF logon manager, although included with VTAM, is an application program; therefore, the logon manager is documented separately from VTAM.
Samples used in this information might not be updated for each release. Evaluate a sample carefully before applying it to your system.
- RoCE Express®, which is a generic term representing IBM® 10 GbE RoCE Express, IBM 10 GbE RoCE Express2, and IBM 25 GbE RoCE Express2 feature capabilities. When this term is used in this information, the processing being described applies to both features. If processing is applicable to only one feature, the full terminology, for instance, IBM 10 GbE RoCE Express will be used.
- RoCE Express2, which is a generic term representing an IBM RoCE Express2® feature that might operate in either 10 GbE or 25 GbE link speed. When this term is used in this information, the processing being described applies to either link speed. If processing is applicable to only one link speed, the full terminology, for instance, IBM 25 GbE RoCE Express2 will be used.
- RDMA network interface card (RNIC), which is used to refer to the IBM® 10 GbE RoCE Express, IBM® 10 GbE RoCE Express2, or IBM 25 GbE RoCE Express2 feature.
- Shared RoCE environment, which means that the "RoCE Express" feature can be used concurrently, or shared, by multiple operating system instances. The feature is considered to operate in a shared RoCE environment even if you use it with a single operating system instance.

How to read a syntax diagram
- Read the diagrams from left-to-right, top-to-bottom, following the main path line. Each diagram begins on the left with double arrowheads (►►) and ends on the right with two arrowheads facing each other (►◄).
- If a diagram is longer than one line, the first line ends with a single arrowhead (►) and the second line begins with a single arrowhead.
- Required operands and values appear on the main path line.
You must code required operands and values.
If there is more than one mutually exclusive required operand or value to choose from, they are stacked vertically in alphanumeric order.
- Optional operands and values appear below the main path line.
You can choose not to code optional operands and values.
If there is more than one mutually exclusive optional operand or value to choose from, they are stacked vertically in alphanumeric order below the main path line.
- An arrow returning to the left above an operand or value on the main path line means that the operand or value can be repeated. The comma means that each operand or value must be separated from the next by a comma.
- An arrow returning to the left above a group of operands or values means more than one can be selected, or a single one can be repeated.
- A word in all uppercase is an operand or value you must spell
exactly as shown. In this example, you must code OPERAND.
Note: VTAM and IP commands are not case sensitive. You can code them in uppercase or lowercase. If the operand is shown in both uppercase and lowercase, the uppercase portion is the abbreviation (for example, OPERand).
If an operand or value can be abbreviated, the abbreviation is described in the text associated with the syntax diagram.
- If a diagram shows a character that is not alphanumeric (such as parentheses, periods, commas, and equal signs), you must code the character as part of the syntax. In this example, you must code OPERAND=(001,0.001).
- If a diagram shows a blank space, you must code the blank space as part of the syntax. In this example, you must code OPERAND=(001 FIXED).
- Default operands and values appear above the main path line. VTAM uses the default if you omit the operand entirely.
- A word in all lowercase italics is a variable. Where you see a variable in the syntax, you must replace it with one of its allowable names or values, as defined in the text.
- References to syntax notes appear as numbers enclosed in parentheses above the line. Do not code the parentheses or the number.
- Some diagrams contain syntax fragments, which serve to break up diagrams that are too long, too complex, or too repetitious. Syntax fragment names are in mixed case and are shown in the diagram and in the heading of the fragment. The fragment is placed below the main diagram.
