Objectives

On successful completion of this course, attendees will be able to:

• describe the structure, operation and the addressing mechanisms used in a TCP/IP network
• list the major configuration steps involved in customising TCP/IP for z/OS and explain the Security Server customisation required in z/OS
• explain the purpose and use of Virtual IP addressing (VIPA) and explain how to code for both a static and dynamic VIPA configuration
• describe how to define devices to TCP/IP for z/OS and explain how to define the TCP/IP for z/OS host IP address(es)
• describe the purpose and customisation of the DATA data set
• define the host name, domain name and DNS information
• describe the purpose and use of the HOSTS file and the SERVICES data set
• explain the configuration of the TN3270 server and the SNA gateway and explain the VTAM configuration required to support the gateway
• implement a VTAM USS table for TN3270 users
• describe the operation and customisation of the FTP server and its major security features
• describe the customisation of the TFTP server
• explain the operation and customisation of the SMTP server and the Routed server
• describe the purpose and use of the major MVS, TSO and USS commands
• explain how to start, stop and interpret a TCP/IP packet trace and a component trace
• describe in overview how SNMP is implemented on z/OS and list the steps involved in customising SNMP under z/OS.>

Who Should Attend

This course is designed for network technicians, systems programmers and technical managers who need an understanding of how TCP/IP for z/OS is installed and configured.

Prerequisites

Attendance on the RSM course 'TCP/IP Fundamentals' or equivalent experience. . A familiarity with UNIX ais also required and some z/OS systems programming experience would be an advantage, but is not essential.
