Chapter 7. X.25 and SNA Networks

You can use an X.25 connection to connect a host machine to a (SNA) network and access a System/370 host.

This information is intended for system administrators responsible for:

• Installing SNA Server/6000.
• Configuring the system to match the network to which it is connected.
• Keeping the system running.

SNA administrators should be familiar with an AIX node and operating procedures for the AIX operating system. Also, they should know the network to which the system is being connected and the general concepts of SNA. In addition, individuals assuming administrative responsibilities should know how to use the System Management Interface Tool (SMIT) . Some of the tasks related to system administration are:

• Customizing AIX SNA Server.
• Starting and stopping SNA Server.
• Defining network security.
• Obtaining network status.

The SNA Server/6000 product provides menu dialogs, commands, and procedures for system administration purposes.
