  1. Chapter 18 Network Communications on z/OS

  2. Objectives • In this chapter, you will learn: • An overview of the communication network model layers • The software components of the z/OS Communications Server product • The difference between a VTAM subarea and APPN network topology • How the IP network can be used to transport data between SNA applications. • Commonly used TCP/IP and VTAM commands

  3. IBM Communications Server

  4. Open Systems Interconnect (OSI) network model

  5. TCP/IP introduction

  6. Interconnecting TCP/IP networks

  7. Internet addressing

  8. TCP/IP commands • TCP/IP Commands can be entered • TSO ready prompt • ISPF Command Shell • Prefixing the command with TSO on any ISPF command line. • NETSTAT • PING • TRACERTE • NSLOOKUP • TELNET • FTP • z/OS UNIX shell prompt (prefix “o”=command) • onetstat

  9. VTAM overview - the SNA environment

  10. A pure VTAM subarea network

  11. APPN topology

  12. Common VTAM commands • D NET,VTAMOPTS Displays VTAM startup options. • D NET,CSM[,OWNERID=ALL] Displays communication storage usage. • D NET,APPLS Displays status of defined applications (ACBs). • D NET,MAJNODES Displays status of VTAM activated ATCCONxx members. • D NET,TOPO,LIST=SUMMARY Displays APPN topology information. • D NET,CPCP Displays status of APPN CP-CP sessions. • D NET,SESSIONS Displays status of subarea SSCP-SSCP sessions. • D NET,CDRMS Displays status of subarea cross domain resource managers. • D NET,EXIT Displays status of VTAM exit points.

  13.
