Configuration 3: Startup Files for Two Hosts Using
an X25AM-Based Connection
Configuring an X.25 Connection for \LA
Consider the organization of the set of command files that you will be examining. There
are four files to look at:

UP1 is the main command file. It invokes X25SUBU1, TCPUP1, and STATUS1.

X25SUBU1 configures the X.25 line and SUs, then starts the line.

TCPUP1 sets the appropriate ADD DEFINEs and starts the TCP/IP process. It
then invokes SCF against TCPSUBU1 which configures SUBNET objects and
ROUTE objects. Then TCPUP1 starts the LISTNER process. Next, it invokes
SCFWNDW1 which configures a TELSERV WINDOW object. Then, TCPUP1
invokes a TACL process against the WINDOW. The TCPUP1 counterpart from the
LAN-based configurations is TCPIPUP.

STATUS1 displays status information about the X.25 line and its SUs and about
the TCP/IP process and its SUBNETs and routes.
UP1: The Main Command File
The command file UP1 acts as the root command file and invokes all the second-level
subordinate command files. Example 3-6 shows a listing of the command file for UP1.
.
Example 3-6. Main Up File for X.25
== TACL command file to bring up TCP/IP over X25 for \LA.
== Set default volume and subvolume
Volume $CB21.TCPIPX25
== Add and start PDN X25 subdevices
scf/in X25SUBU1/
delay 10 sec
== Start TCP/IP Subsystems.
OBEY TCPUP1
== Status everything
SCF/in STATUS1/
Command Description
VOLUME $CB21.TCPIPX25
sets the default volume and subvolume to point to
the subvolume that contains the command files.
SCF /IN X25SUBU1/
invokes SCF against the command file X25SUBU1.
This command file configures X.25 line attributes
and SUs.
