Once a configuration file is successfully opened or created, NMMGR displays the Main screen, shown in Figure 3-2 "Main Screen". This screen presents a menu from which you select the group of NMMGR screens you need to configure the appropriate subsystem.

Figure 3-2 Main Screen

The main screen also contains three data fields that must be completed in order to configure the local node name and determine which type of network configuration is appropriate for the node.

The following steps describe the action that should be taken at the Main screen:

Enter the node name of the system you are configuring in the local node name field (if it is not already present).
In the field next to the question Are you using OpenView DTC Manager?, enter a "Y" if you are using PC-based network management for this node, enter an "N" if you are using host-based network management. If you are using PC-based network management, an OpenView workstation must be present on the network.
In the field next to the question Do you have X.25 system-to-system or PAD connections?, enter a "Y" to indicate you will be configuring a DTC/X.25 Network Access card for this node, otherwise, enter an "N".
Press the [Save Data] key to save the node name in the configuration file (create the data record). The Data flag will be set to "Y" when the data record exists.
Proceed to one of the NMMGR configuration subbranches by pressing the appropriate function key.

Each of the configuration subbranches are described.

Configuring Terminals, Printers, and Other Serial Devices

Terminals, printers, and other serial devices are connected to HP e3000 computers through a device called the Datacommunications and Terminal Controller (DTC). In order to connect to a device, the system's configuration file must contain information that makes it possible for the DTC, as well as the devices attached to the DTC, to establish communications with the system. DTCs and their devices are configured through NMMGR's distributed terminal subsystem (DTS) configuration.

If you press the key labeled [DTS] at the Main screen, you will be taken to the Host Configuration screen (Figure 3-3 "Host Configuration Screen"), the first screen in a progression that lets you configure DTS for Host-based network management only. The PC-based management screen will vary slightly.

Figure 3-3 Host Configuration Screen

You will perform a number of tasks using these screens, including the following:

Define the DTS link configuration for the system.
Define connection capabilities for terminals, printers, and other serial devices that will be able to communicate with the system.
Define terminal, printer, and other serial device profiles specifying sets of characteristics that can be applied to various terminals, printers, or other serial devices connected to the system and associate the profiles with individual devices. The screen in Figure 3-4 "NS Configuration Screen" reflects PC-based network management only. The Host-based management screen will vary slightly.

See the following manuals for more information on configuring DTCs and serial devices:

Configuring NS 3000/iX

The NS 3000/iX product consists of NS 3000/iX Network Services and NS 3000/iX links. NS 3000/iX Network Services contain software that allows you to access data, initiate processes, and exchange information between all the systems on a network. NS 3000/iX links provide connections between systems (either HP e3000s or personal computers) in a network. To use NS 3000/iX Network Services, the systems must be connected by an NS 3000/iX link and each link must be properly configured through NMMGR.

If you press the key labeled [NS] at the Main screen, you are taken to the NS Configuration screen (Figure 3-4 "NS Configuration Screen"), the first screen in a progression that lets you configure NS.

Figure 3-4 NS Configuration Screen

NMMGR provides two methods of creating or updating configuration information for an NS link. The methods are referred to as Guided Configuration and Unguided Configuration respectively. You determine which method you will use by making a choice at the NS Configuration screen.

You also use this screen to configure a domain name for the node you are configuring if using domain names for network access. To configure a domain name, replace the local node name in the field at the bottom of the screen and press the [Save Data] key. (If you are not using domain names, leave the local node name as is.)

To perform guided configuration, press the key labeled [Guided Config] and refer to the HP e3000/iX Network Planning and Configuration Guide for information.
To perform unguided (manual) configuration, press the key labeled [Unguided Config] and refer to the NS 3000/iX NMMGR Screens Reference Manual for information.

NOTE: Hewlett-Packard strongly recommends using guided configuration whenever you need to initially configure a network interface. You can also take advantage of its convenience later for most network maintenance and updating. Guided configuration supplies many default values for your configuration and requires that you visit a minimal number of screens. Use unguided configuration only if you need to modify configuration values that are not available on the guided screens.

Guided Configuration

If you press the key labeled [Guided Config] at the NS Configuration screen, you will be taken to the Network Transport Configuration screen shown in Figure 3-5 "Network Transport Configuration Screen". From this screen, you choose the specific task you want to perform using guided NS configuration. These tasks include configuring or modifying a network interface, modifying logging parameters, and fine tuning global or network transport configuration parameters.

Figure 3-5 Network Transport Configuration Screen

Guided configuration is a procedure that automates part of the configuration process. It "guides" you through the configuration screens for a specific task. It assumes and supplies default values wherever possible to furnish most of the configuration file's data.

When you run guided configuration, you use only a minimal number of configuration screens. You will normally use fewer screens than you would if you were performing the same task using unguided configuration. Many of these screens are different from those used for unguided configuration.

Unguided Configuration

If you press the key labeled [Unguided Config] at the NS Configuration screen (#166), you will be taken to the Unguided Configuration screen shown in Figure 3-6 "Unguided Configuration Screen".

Figure 3-6 Unguided Configuration Screen

From this screen, you can move to the screens that let you:

Configure or modify a network interface.
Configure or modify an NS link.
Configure or modify logging parameters.
Configure or modify a network interface.

If you choose to create or modify an NS configuration using unguided (manual) configuration, you must take care that you know which screens you need to use to completely create or modify a configuration. The unguided nature of manual configuration makes it possible to get "lost" or to miss some necessary screens entirely.

Under most circumstances, HP recommends that you use guided configuration. Unguided configuration can be useful, however, if you only need to use a few screens and you know exactly which screens you need.

Refer to the NS 3000/iX Screens Reference Manual for information on the unguided NS configuration screens.

Configuring HP-IBM Connections

Hewlett-Packard provides a number of networking products that make it possible to establish communication links between HP e3000 and IBM mainframe computers.

If you press the key labeled [IBM] at the Main screen, you are sent to the HP-IBM Configuration screen shown in Figure 3-7 "HP-IBM Configuration Screen".

Figure 3-7 HP-IBM Configuration Screen

From this screen, you can choose any of the IBM subsystems for configuration by pressing the appropriate function key. You can also choose to configure logging for all of the IBM subsystems, or you can choose SNANODE configuration (SNA node, SDLC link, X.25 link, and token ring link).

The HP-IBM Configuration screen presents you with more choices than there are available function keys. For this reason, the screen includes a [Next Key Labels] function key that lets you toggle between two sets of function key choices. If the choice you want does not currently appear on any of the [Go to] function keys, press the [Next Key Labels] key. You can then make the choice you need to configure the HP-IBM subsystem you want to configure.

For more information on configuring any of the HP-IBM products, see the Node Manager's Guide for that product. For information on HP-IBM subsystem logging or SNANODE configuration, see the SNA Link/iX Node Manager's Guide.
