The procedures that follow describe how to modify the NMMGR

conﬁguration ﬁle and network directory ﬁle for X.25 iX System Access

conﬁguration. These procedures assume that you have already

conﬁgured the datacommunications and terminal subsystem (DTS) for

this system. See Chapter 3, “Conﬁguring DTCs Step-by-Step,” for

information on DTS conﬁguration.

Step 1: Begin the Conﬁguration Process

Run the NMMGR program. Node manager (NM) or network

administrator (NA) capabilities are required to run this program. To

run NMMGR:

1. Type NMMGR.PUB.SYS at the MPE/iX prompt (:).

2. Press

[Return].

NOTE

You cannot modify the X.25 iX transport and link conﬁgurations in

NMCONFIG.PUB.SYS if the Network Services are active. Verify that the

Network Services are not running by issuing the NETCONTROL STATUS

command. You must have NM (Node Manager) capability to issue this

command.

If NS is down, you will see the following two messages in response to

the NETCONTROL STATUS command:

TRANSPORT NOT ACTIVE. (NETXPORTWARN

0001) ENCOUNTERED ONE OR MORE WARNINGS

WHILE PROCESSING COMMAND. (CIWARN 4437)

Step 2: Open the Conﬁguration File

The ﬁrst screen that NMMGR displays is the Open

Conﬁguration/Directory File screen (Figure 6-1). You should already

have created the conﬁguration ﬁle you are using when you conﬁgured

DTS. (If you have not already conﬁgured DTS, stop here, and go to

Chapter 3, “Conﬁguring DTCs Step-by-Step,” for step-by-step

instructions.
