Preface This manual documents functionality for the MPE/iX 6.0 release, as well as later releases for HP e3000 systems. This reference manual assumes that you are familiar with your network topology. NMMGR is an interface used to configure Local Area Networks (LANs), point-to-point (router) networks, Token Ring networks, FDDI, 100VG-AnyLAN, 100Base-T, and X.25 networks.
Special Note MPE/iX, Multiprogramming Executive with Integrated POSIX, is the latest in a series of forward-compatible operating systems for the HP e3000 line of computers. In HP documentation and in talking with HP e3000 users, you will encounter references to MPE XL, the direct predecessor of MPE/iX. MPE/iX is a superset of MPE XL. All programs written for MPE XL will run without change under MPE/iX.
Helpful Manuals This manual is intended as a reference for those who need detailed information about NS 3000/iX configuration screens and their fields. Not all parts of the NMMGR screens set are described in this manual. The following paragraphs describe where to find information about other aspects of NMMGR and network configuration. The planning you should do before attempting to configure a network is discussed in the HP e3000/iX Network Planning and Configuration Guide.
Related Publications • HP e3000/iX Network Planning and Configuration Guide provides information for planning your network and also provides step-by-step instructions for using guided configuration to configure network links. • System Startup, Configuration, and Shutdown Reference Manual provides the information on how to determine the physical paths of I/O cards installed in the system.
1 Overview NS 3000/iX network subsystems on HP e3000 computers are configured using a utility called the node management configuration manager (NMMGR). NMMGR uses a series of VPLUS screens to display and accept configuration data. Configuration data is stored in a hierarchically structured file, of file type NCONF, called NMCONFIG.PUB.SYS. The network services, network transport, data communications configurator, and logging services use NMCONFIG.PUB.SYS to get the information they need to operate.
Overview Using the Command Window Using the Command Window The command window at the top of each NMMGR screen is used to enter NMMGR or MPE commands. The command window is the third line from the top of an NMMGR screen and has Command: on the left-hand side. You type a command in the command window and execute it by pressing the [Enter] key. The [Enter] key is the block mode enter key, different from the carriage return key.
Overview Using the Path Name Using the Path Name The path name is used to go directly to a given screen. A path name may include one or more of the following variables: • NIname is the name of the network interface you want to modify. • linkname is the name of the link you want to modify. • gatewayn is the name of the gateway you want to modify. • mapentry is the name of the entry you want to modify in the router mapping table. • fsetname is the name of the X.25 facility set you want to modify.
Overview Getting Help Getting Help Help is available for all the NMMGR screens described in this manual. It is also available for the screens used to configure the distributed terminal subsystem and those used for guided configuration. There are two ways to access NMMGR help: • The simplest way to use the help facility is to press the [Help] function key while at the screen for which you need information.
Overview Using This Manual Using This Manual This manual is organized so that you can find information on specific screens in any of the following ways: • If you know the name of the screen you need information about, you can refer to the index for an alphabetical listing of screens by name. • Screens are arranged in this manual by screen type. If you know both the screen’s name and its type you can locate screens easily using the Table of Contents.
Overview Software Configuration Maximums Software Configuration Maximums The following are the software maximums in Table 1-1 that must be adhered to when configuring a supported link. These maximums may be further limited by the system hardware (number of available slots). Maximums are also documented throughout the manual for the appropriate screen.
Introductory Screens 2 The introductory screens are the first few screens that are displayed when you configure a node using NMMGR. Figure 2-1 shows the screen flow of the introductory screens. [FUNCTION] denotes the function key used at a screen to invoke the next screen on the screen flow. This Chapter describes the introductory screens relevant to configuring NS using unguided configurations.
Introductory Screens Open Configuration Directory File Open Configuration Directory File The Open Configuration/Directory File screen (#1) shown in Figure 2-2 is the first screen displayed when you run NMMGR. Figure 2-2 Open Configuration/Directory Screen To create or modify a configuration, enter the configuration file name and press the [Open Config] key. If the configuration file does not already exist, NMMGR will ask you to press the [Open Config] key again to confirm creation.
Introductory Screens Open Configuration Directory File NOTE The write access password is optional. If you do not choose to assign a password, you will be able to update the configuration file at any time it is opened. For information on how to assign a write access password, refer to the information about the password maintenance mode command in Using the Node Management Services (NMS) Utilities.
Introductory Screens Open Configuration Directory File Network directory screens are discussed in Chapter 13 , “Network Directory,” of this manual. Write access password The password is an optional feature. If a password has been assigned, you must enter the password in the write access password field in order to update the configuration file. It is still possible to open the file without using an assigned password, but the file will be in read only mode and NMMGR will accept no changes to the file.
Introductory Screens Main Main If you create or modify a configuration file and press the [Open Config] key from the Open Configuration/Directory File, the Main screen (#2) shown in Figure 2-3 appears. Figure 2-3 Main Screen At the Main screen you configure the local node name of the HP e3000 host system. Before you can proceed beyond the Main configuration screen you will need to enter a valid local node name, answer the questions asked on the screen, and press the [Save Data] key.
Introductory Screens Main Assign meaningful node names. For example, MKTG.IND.HP and LAB.IND.HP are meaningful names for two nodes on the same Local Area Network within Hewlett-Packard. One node (MKTG.IND.HP) is used by the marketing department. The other node (LAB.IND.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.
Introductory Screens Main NMMGR Configuration Subbranches To select one of the NMMGR configuration subbranches (DTS, NS, OSI, IBM and Utility), press the appropriate function key. To configure Datacommunications and Terminal Controllers (DTCs) and the devices attached to them, press the [DTS] function key and refer to Configuring Systems for Terminals, Printers, and Other Serial Devices.

Network Transport Configuration Screens Transmission Control Protocol (TCP) Configuration The algorithm used for congestion and flow control is based on the Van Jacobson algorithm which uses the initial retransmission timeout for most calculations. The initial retransmission timeout is the greater of the following two values: 1. The value you configure in the Retransmission interval lower bound field. 2.
Network Transport Configuration Screens Transmission Control Protocol (TCP) Configuration performance. Values to be entered for the retransmission fields should, in general, reflect the average load on system resources at the local node, the remote node, and the intervening network(s), if any. The optimal values for these fields can be determined only by experience for each node. Fields Checksum enabled Checksumming is a method of error checking used for reliability.
Network Transport Configuration Screens Transmission Control Protocol (TCP) Configuration of user or Network Services data over TCP connections. The number of connections configured should reflect an estimation of the number of Network Services and NetIPC users that will be active simultaneously. This includes both outbound and inbound connections. The value configured should be relatively large to accommodate expansion. Note that the allocation of buffers is related to the number of TCP connections.
Network Transport Configuration Screens Transmission Control Protocol (TCP) Configuration Maximum retransmissions per packet This is the maximum number of times that TCP will retransmit a packet before aborting the connection. Increase the value if connections are being dropped prematurely. Decrease the value if there is too much traffic due to packet retransmission.

Each subsystem includes different classes of events (such as internal errors). You can record logging to a disk file for later analysis, to the system console so that the system operator receives the messages, or both. You can also display logging events at individual users’ list devices.
Logging Configuration Screens Activating Logging Activating Logging NetIPC logging is automatically activated at system startup. Network Services logging is activated when the Network Services are initiated (i.e., when the NSCONTROL START command is issued). Link manager logging and network transport logging are activated when you initiate the network transport (NETCONTROL START).

Network Directory 13 The screens in this chapter are those you would see when configuring the Network Directory. The Network Directory branch of NMMGR begins with a screen called the Network Directory Main screen. Figure 13-1 shows the screen flow for configuring the Directory screens. Screens unique to the Network Directory are indicated by bold boxed screens. [FUNCTION] denotes the function key used at a screen to invoke the next screen on the screen flow.
Network Directory You use NMMGR to perform the following network directory functions: • Add, modify, and delete entries in the directory. • Review and inspect directory information. • Merge a remote directory with a directory on the local node. • Automatically update directories on a group of remote nodes by using a background stream job, controlled from a central administrative node. Central administrative nodes are described in more detail later in this chapter.
Network Directory What a Network Directory Provides What a Network Directory Provides A network directory is used by the node for internetwork routing. Each entry in a network directory consists of a node name associated with an IP address, the network type, and an additional address, if necessary. The network directory uses the internet protocol (IP) address to transfer data between networks. When a Network Directory is Required A network directory must be configured on nodes with X.25 links.
Network Directory What a Network Directory Provides purposes, you should designate at least two nodes on a LAN to be proxy servers. A node is configured as a proxy server in the Probe Protocol Configuration screen, (path name NETXPORT.NI.NIname.PROTOCOL.PROBE). Path Report Lists A path report is an internal structure containing all configured paths to a given IP address in the internet. The path report list is a list of all path reports in a network directory.
Network Directory Planning the Network Directory Planning the Network Directory There are two schools of thought on how network directories should be planned and configured on a network, as follows: • Centralized network directories. • Decentralized network directories. The centralized school of thought requires each node on the internet to have the same network directory. This means that every node in the network must have an entry in the network directory.
Network Directory Planning the Network Directory Once a network directory has been established on each node in the internet, you can set up a job stream to automate network directory updates. The MERGEDIR command is part of a maintenance interface provided primarily to support the updating of directories using a batch job. Using this method, a job or series of jobs can be scheduled at regular intervals to copy and then merge remote directories into the local-system directory.
Network Directory Open Configuration/Directory File Open Configuration/Directory File The Open Configuration/Directory File screen (#1) shown in Figure 13-2 is the first screen displayed when you run NMMGR. Figure 13-2 Open Configuration/Directory File Screen To create or modify a network directory, enter the network directory file name (and write access password, if one is required) and press the appropriate function key. The name NSDIR.NET.SYS is used by the network subsystems.
Network Directory Network Directory Main Network Directory Main The Network Directory Main screen (#8) shown in Figure 13-3 is displayed when you press the [Open Directry] or the [Create Directry] function key at the Open Configuration/Directory File screen (#1) as shown in Figure 2-2. This screen is also displayed if a network directory has already been opened and you type NETDIR in the command window of any screen and press the [Enter] key.
Network Directory Network Directory Main Press the [Maint Mode] function key to enter the command interface to perform directory merging or to expand the size of your directory. Refer to Using the Node Management Services (NMS) Utilities for details on maintenance mode. Within the maintenance mode interface, command input is read from the formal designator NMMGRCMD, which defaults to $STDINX. Type EXIT and press the [Return] key to leave maintenance mode.
Network Directory Network Directory Select Node Name Network Directory Select Node Name The Network Directory Select Node Name screen (#9) shown in Figure 13-4 is displayed when you press the function key for [Update Dir] at the Network Directory Main screen (Figure 13-3). The function of this screen is to display node names that are currently configured in the directory, and to allow you to delete, rename, add, or modify information about a node.
Network Directory Network Directory Select Node Name • To change the name of a node in the directory, specify the node name and a new name; then press the [Rename] function key. The previously configured node name is replaced and the screen displays the new name in a display field under the label Configured Entries. Fields Node name The name of the node for which you want network directory information.
Network Directory Network Directory Select Node Name Other uses of local entries include restricting certain nodes from communicating with the internet, or being able to direct which way to access remote nodes depending on your configuration of local entries. When both local and global entries exist for the same node, the network transport uses the local entry. Default value: Y Range: Y or N New name (Required only when renaming an existing node name.
Network Directory Network Directory Data Network Directory Data The Network Directory Data screen (#10) shown in Figure 13-5 is displayed when you press the [Add] or [Modify] function key at the Network Directory Select Node Name screen (Figure 13-4). Figure 13-5 Network Directory Data Screen The function of this screen is to configure path report data for the node name listed at the top of the screen. One path report is configured for each NI on a node.
Network Directory Network Directory Data then checksums are used when communicating with this node. Checksumming is required for communication to non-HP systems. The default is N. PXP PXP must be Y (yes) for all nodes. The default is Y. Note that the selection of transport services here must match the settings in the remote node’s configuration file. If the checksum enabled field in the path NETXPORT.GPROT.
