The procedures that follow describe how to modify the NMMGR
configuration file for the introductory screens. To Start NMMGR | |
Node manager (NM) or network administrator (NA) capabilities
are required to run this program. To run NMMGR: Type NMMGR.PUB.SYS
at the system prompt (:). Press [RETURN].
To Open the Configuration File | |
The Open Configuration/Directory File screen (#1) in Figure 5-2 “Open Configuration/Directory File
Screen” is the first screen displayed
when you run NMMGR. Figure 5-2 Open Configuration/Directory File
Screen
![[Open Configuration/Directory File Screen]](img/gfx20.gif)
Follow the steps listed here to enter data for this screen.
Refer to "Fields" subsection for detailed information
about each field on the screen. Verify that the correct configuration file
name, backup configuration file name, and network directory file
name are in the appropriate fields. If you have assigned a write access password, enter
it in this field. If you are not using the password feature, leave
this field blank. Press the [Open Config] key. If you
are creating the configuration file for the first time, NMMGR will
ask you to verify creation. Press the [Open Config]
key again to continue. Fields- configuration file name
The only configuration file name the system recognizes for use by
the network subsystem is NMCONFIG.PUB.SYS.
You can,
however, create or modify a configuration file using a different
name and save it as an offline configuration file. You can use offline configuration
files as a means of creating and storing configurations that you
want to use in the future or that you are preparing for use on a
different system. When you are ready to use an offline
configuration file, rename it as NMCONFIG.PUB.SYS
and reboot the system. (Keep in mind that any file you use as a
configuration file must be successfully validated before you try
to use it.) - Backup configurationfile name
A backup file name must be specified whenever a configuration
file is opened or created. The default backup configuration file
name is NMCBACK.group.account.
The backup file will be automatically updated with the contents
of the configuration file each time the configuration file is successfully
validated. - Network directory file name
A network directory must be configured in the following
circumstances: nodes not using domain name services nodes on a LAN network that do not support the HP-PROBE
protocol
The only network directory file name supported by HP is NSDIR.NET.SYS.
This file is part of a KSAM pair. A key file is created at the same
time as this data file. The key file will automatically be named
using the first six letters of the network directory file name,
appended with the character K.
For example, NSDIRK.NET.SYS is the name of
the key file associated with the data file NSDIR.NET.SYS.
If the name of the data file is less than six letters long, then
the entire file name would be appended with a K. - Write access password
The password is an optional feature. If a password has been assigned,
you must enter it in the password field to update the configuration
file or the directory file. It is still possible to open an existing
file without using an assigned password, but the file will be in
read only mode and NMMGR will not accept changes. If a password has not been assigned, you should ignore the
password field. If you want to assign a password for the system you are configuring,
see Using the Node Management Services (NMS) Utilities.
To Select NS Configuration | |
To Select NS Configuration. The Main screen (#2) in Figure 5-3 “Main Screen” is displayed after you create or open
a configuration file by pressing the [Open Config]
key from the Open Configuration Directory File screen (#1) in Figure 5-2 “Open Configuration/Directory File
Screen”. Figure 5-3 Main Screen

removed from the Corporate Price List. The product is obsolete with
no plans for support. | | | | |
Ensure that the information in the fields
on this screen is correct. If not, or if the information has not
been entered, specify the correct information and press the [Save Data]
key. (See Configuring Systems for Terminals, Printers,
and Other Serial Devices for information about configuring
the information on this screen.) When you are satisfied with the information as configured,
press the [NS] key to select the NS configuration
branch.
Fields- Local node name
The local node name is the name by which the HP 3000 Series 900
computer is known in the network. The format of a node name is nodename.domain.organization
where the total number of characters is 50 or fewer, and each field
contains 16 or fewer characters (alphanumeric, underscore, or hyphens).
The first character of each field must be alphabetic. The nodename portion of each node name
must be unique within the node's network. The nodename.domain
portion of each node name must be unique within the internetwork.
HP recommends that all nodes on the network be assigned the same
domain and organization. Assign meaningful node names. For example, MKTG.BND.HP
and LAB.BND.HP are meaningful names for two
nodes on the same network within Hewlett-Packard. One node (MKTG.BND.HP)
is used by the marketing department. The other node (LAB.BND.HP)
is used by the lab. The domain field is the
same because the nodes belong to the same network. The organization
field is the same because the nodes belong to the same internetwork. - Are you using OpenView DTC Manager?
If you answer yes to this question, NMMGR assumes
you are using a PC to manage your system and takes you to the corresponding
set of screens when you configure DTS. If you answer no, NMMGR assumes
you are using host-based network management and takes you to a different
set of DTS screens. You should already have answered this question
when you configured DTS. - Do you have X.25 system- to-system or PAD connections?
If you answer yes to this question, NMMGR assumes
you are configuring X.25 connections and takes you to the set of
screens required to configure DTC X.25 Network Access Cards when
you configure DTS. If you answer no, NMMGR assumes you have no need
to configure X.25 connections and takes you to a different set of
DTS screens. You should already have answered this question when
you configured DTS.
To Select Guided Configuration | |
The NS Configuration screen (#166) in Figure 5-4 “NS Configuration Screen” is displayed if you press the [NS]
key at the Main screen (#2) in Figure 5-3 “Main Screen”. Figure 5-4 NS Configuration Screen
![[NS Configuration Screen]](img/gfx22.gif)
If you are using domain names for network
access, replace the node name in the field at the bottom of the
screen with this system's domain name and press the [Save Data]
key. If not using domain names, leave the node name as is. Press the [Guided Config] key to proceed
with guided configuration of LAN.
Guided/Unguided Configuration | |
Hewlett-Packard recommends that you press the [Guided Config]
key to select the guided configuration branch whenever you need
to initially configure a network interface. Guided configuration
supplies many default values for your configuration and requires
that you visit a minimal number of screens. This manual provides
information on every screen available to you through unguided NS
configuration. The [Unguided Config] key is used to modify
configuration values that are not available in the guided screens.
To use the unguided configuration screens, refer to the NS
3000/iX NMMGR Screens Reference Manual. Fields- Local Domain Name
The name of this system in the ARPANET standard
format. This name can be used by other nodes on the network to access
this host. The domain name is composed of labels, with each label separated
by a period. Each label must start with a letter or digit, and have
as interior characters only letters, digits, hyphens (-), or underbars
(_). A domain name may have any number of labels, but its total
length, including periods, is limited to 255 characters. label[.label][...] Domain names are not case sensitive. Use of domain names is optional. If you are not using domain
names for network access, leave the local node name in this field.
To Perform Guided Network Transport Configuration | |
The Network Transport Configuration screen
(#42) in Figure 5-5 “Network Transport Configuration Screen” is displayed
if you press the [Guided Config] key at the NS
Configuration screen (#166) in Figure 5-4 “NS Configuration Screen”. Figure 5-5 Network Transport Configuration Screen
![[Network Transport Configuration Screen]](img/gfx23.gif)
Next to the words Enter a network interface:,
enter a name for the selected network interface (for example, LANNI). Next to the words Enter a network type:,
enter the selected network type number indicated on the above screen.
(For example, enter a 1 to indicate
that the NI is a LAN NI.) Press the [Config Network] key. (There
may be a short pause before the next screen appears.) | | | | | NOTE: NS/SNA is no longer offered as a product and has been
removed from the Corporate Price List. The product is obsolete with
no plans for support. | | | | |
Proceed to the chapter of the network interface selected
above for screen information. Refer to Chapter 6 “Configuring a LAN, Token Ring, FDDI,
100VG-AnyLAN, 100Base-T Node” for information on LAN, Token Ring, FDDI,
100VG-AnyLAN, and 100Base-T; and other chapters for information
on Point-to-Point, X.25, and Gateway Half respectively.
Fields- Enter a network interface
The network name (NI name) is used to easily identify
one of the types of network interfaces: LAN, Token Ring, FDDI, 100VG-AnyLAN,
100Base-T, NS Point-to-Point, X.25 or Gateway Half. The name can
be up to eight alphanumeric characters, starting with a letter.
The maximum number of NIs that can be configured on a node is 12.
One of the 12 allowable NIs is reserved for loopback.
(Loopback is configured for you automatically.) If a node interfaces to more than one network, give each NI
on that node a unique name. Although all nodes on the same network
do not have to have the same NI name, it will be easier to remember
if you make the NI name the same for all nodes on the same network
(for instance, LANNET). You will use the NI
name with the NETCONTROL command to start the
transport and network link. - Enter a network type
Number that indicates the type of network interface
you are configuring. You must enter a network type if you are configuring
a new network interface. Refer to the following for what number
to enter: | Enter 1 for a LAN NI | | Enter 2 for a Point-to-Point (router) NI | | Enter 3 for an X.25 NI | | Enter 4 for an SNA NI | | Enter 5 for a Gateway Half NI | | Enter 6 for a Token Ring NI | | Enter 7 for an FDDI NI | | Enter 8 for 100VG-AnyLAN | | Enter 9 for 100Base-T |
