Changing the Initial WAN Subsystem Configuration

Change Procedure

The general method for changing the system configuration is as follows:

1. Create a command file containing the SCF commands to implement a

configuration change. You can use the SCF0000, STARTCOM, and/or STARTSCF

command files created by HP manufacturing as templates.

2. For fallback purposes, save the current initial manufacturing configuration

(CONFIG file) by using the SCF SAVE command. This example shows how to

save the current CONFIG file to a file named CONF0102 on the

$SYSTEM.ZSYSCONF subvolume:

1-> save configuration 1.2

3. Invoke the SCF command file created in Step 1. For example:

2-> obey scfconf

This method saves a copy of a known, stable configuration so you can restore the

previous configuration (if necessary).

Reconfiguring the DEVICE Objects That Use

the WAN Ports

All WAN ports (depending on the type of concentrator) on your SWAN concentrator are

preconfigured and started as ATP6100 lines for testing purposes by HP manufacturing.

The ATP6100 subsystem allows for an application program to use asynchronous point-

to-point terminals, printers, and other devices connected through the SWAN

concentrator.

To reconfigure an ATP6100 line—for example, to change it to an X25AM line:

1. Stop the ATP6100 line using the ATP6100 subsystem SCF STOP LINE command.

2. Stop the ATP6100 line-handler process using the SCF STOP DEVICE command.

3. Delete the ATP6100 line-handler process using the SCF DELETE DEVICE

command.

SERVER Represents one communications line interface processor (CLIP).

SUBSYS Represents the WAN manager process, $ZZWAN.*

TASK Represents a data link control (DLC) task.

*Because the WAN manager process is configured as a subsystem manager process in the NonStop Kernel

subsystem, you must use the NonStop Kernel subsystem SCF interface to configure and control it. The SCF

interface to the NonStop Kernel subsystem is described in the

SCF Reference Manual for the Kernel Subsystem.
