Steps for setting up a SNALINK LU6.2 network

This list of steps can be used to diagnose problems in starting components by identifying the prerequisites. For details about how to complete the steps, see the appropriate documentation.

Procedure

Complete the following steps to establish the system that is described in Figure 1.

  1. Configure the SNALINK LU6.2 network on both the local and remote network hosts. This is fully described in z/OS Communications Server: IP Configuration Reference in the section about configuring and operating the SNALINK LU6.2 interface. The process can be condensed into the following steps:
    1. Specify SNALINK LU6.2 DEVICE and LINK statements in the hlq.PROFILE.TCPIP data set.
    2. Copy the sample SNALINK LU6.2 cataloged procedure to an authorized data set and update according to your system.
    3. Define a SNALINK LU6.2 application LU to VTAM®.
    4. Customize a SNALINK LU6.2 configuration data set.
  2. Vary the SNALINK LU6.2 VTAM application LUs active on both the local and remote network hosts.
  3. Start both the local and remote network TCP/IP address spaces.
  4. Start both the local and remote network SNALINK LU6.2 address spaces, if they have not been autologged by the TCP/IP address space.
  5. Verify that the network connection has been established between the local host and the remote host. See Using the SNALINK LU6.2 subcommand for details about how to verify SNALINK LU6.2 connections.

Results

The example in Figure 1 shows the messages that are expected when the SNALINK LU6.2 address space is started and a network connection is established.

The following list explains the MVS™ system console messages on SNALINK LU6.2 address space startup as shown in Figure 1.
 1 
The SNAL621A address space has been started.
 2 
The SNALINK LU6.2 configuration data set for the SNAL621A address space has been successfully parsed.
 3 
The SNAL621A address space displays its local VTAM application LU and the TCP/IP address space name to which it connects.
 4 
The SNAL621A address space establishes a network connection through the VTAM API.
 5 
The SNAL621A address space establishes a DLC connection with its TCP/IP address space.
