Preface This manual documents functionality for the MPE/iX 6.0 release, as well as later releases for HP 3000 Series 900 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.
An introduction to the generic use of the NMMGR utility, including discussions of the first levels of selection menus and of the utility screen branch, can be found in Using the Node Management Services (NMS) Utilities. The NMMGR screens that are associated with configuring the terminal, printer, and other serial device connections made through the Datacommunications and Terminal Controller (DTC) are described in Configuring Systems for Terminals, Printers, and Other Serial Devices.
1 Overview NS 3000/iX network subsystems on HP 3000 Series 900 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.
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 (MPE/iX 6.0) Software Configuration Maximums (MPE/iX 6.0) 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.
2 Introductory Screens 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 15, “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 3000 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 The name portion of each node name must be unique within the node’s network. The name.domain portion of each node name must be unique within the internetwork. HP recommends that all nodes on the same network be assigned the same domain and organization. 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.
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.
Introductory Screens NS Configuration NS Configuration If you press the [NS] function key from the Main screen, the NS Configuration screen (#166) shown in Figure 2-4 appears.

4 Network Transport Configuration Screens This section contains information about the NMMGR configuration screens that are common to all network interfaces. The network transport configuration branch of NMMGR begins with a screen called the Network Transport Configuration Selection screen. Figure 4-1 shows the screen flow for configuring the Network Transport Configuration screens. Screens unique to the Network Transport Configuration are indicated by bold boxed screens.
Network Transport Configuration Screens The Network Transport Configuration Selection screen allows you to define global parameters for the node as well as network interfaces of type LAN, ROUTER (point-to-point), X.25, SNA, TOKEN (token ring), FDDI, 100VG-AnyLAN, 100Base-T, Gateway Half, or Loopback. To reach the network transport configuration screens, run NMMGR, and refer to the following pages of this section for a step-by-step process. Step-by-Step Process: Step 1. Run NMMGR.
Network Transport Configuration Screens Network Transort Configuration Selection Network Transort Configuration Selection The Network Transport Configuration Selection screen (#154) shown in Figure 4-2 is displayed when you press the function key for [Go To NETXPORT] at the Unguided Configuration screen (#80).

Network Transport Configuration Screens Global Transport Configuration Default value: 2, 3, 1 (Probe, Probe Proxy, Network Directory) Range: 0–3 NOTE If you are using domain names, the domain name can be resolved via either the domain name resolver or host tables. See the HP 3000/iX Network Planning and Configuration Guide for more information on domain names. Maximum inbound buffer memory (in kilobytes) This configures the amount of memory used to store incoming data.
Network Transport Configuration Screens General Protocol Configuration General Protocol Configuration The General Protocol Configuration screen (#153) in Figure 4-4 is displayed when you press the [Go To GPROT] function key at the Network Transport Configuration Selection screen (Figure 4-2). It is also displayed when you type the path name: @NETXPORT.GPROT in the command window of any screen and press the [Enter] key.
Network Transport Configuration Screens Packet Exchange Protocol (PXP) Configuration Packet Exchange Protocol (PXP) Configuration The Packet Exchange Protocol (PXP) Configuration screen (#93) in Figure 4-5 is displayed when you press the [Go To PXP] function key at the General Protocol Configuration screen (Figure 4-4). It is also displayed when you type the path name: @NETXPORT.GPROT.PXP in the command window of any screen and press the [Enter] key.
Network Transport Configuration Screens Packet Exchange Protocol (PXP) Configuration Fields Checksum enabled (Y/N) Checksumming is a method of error checking. Enter a Y (yes) to enable checksumming for all sockets for this protocol. Enter an N (no) to allow individual sockets to choose checksumming for themselves. PXP checksumming causes significant overhead, and is not normally needed for this protocol. Also, error checking is provided for at the link level.
Network Transport Configuration Screens Packet Exchange Protocol (PXP) Configuration would cause unacceptably long delays before IPCLookup would fail under normal conditions such as the remote node failing.
Network Transport Configuration Screens Transmission Control Protocol (TCP) Configuration Transmission Control Protocol (TCP) Configuration The Transmission Control Protocol (TCP) Configuration screen (#94) in Figure 4-6 is displayed when you press the [Go To TCP] function key at the General Protocol Configuration screen (Figure 4-4). It is also displayed when you type the path name: @NETXPORT.GPROT.TCP in the command window of any screen and press the [Enter] key.
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.
Network Transport Configuration Screens Transmission Control Protocol (TCP) Configuration Connections may be prematurely aborted if you set retransmission interval lower bound low and you set maximum time to wait for remote response or maximum retransmissions per packet low. All of these retransmission fields are configurable to optimize connection performance.
Network Transport Configuration Screens Transmission Control Protocol (TCP) Configuration flow control and retransmissions. TCP connections and NetIPC have a one-to-one correspondence for calls to IPCCONNECT, and therefore between each Network Service invoked by each user. There is no multiplexing 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.
Network Transport Configuration Screens Transmission Control Protocol (TCP) Configuration Initial retransmission interval (secs) This field sets the initial amount of time that TCP will wait for a reply from a remote node before attempting to retransmit a packet. This value is used for connection setup when the retransmission interval has not yet been calculated. It should be greater than the retransmission interval lower bound.
Network Transport Configuration Screens Transmission Control Protocol (TCP) Configuration Maximum connection assurance retransmissions This is the maximum number of times that TCP will transmit a connection assurance packet to a non-responding remote system. Together with the connection assurance interval, this value defines the time it will take for an idle connection to abort if the remote TCP fails to respond. Unlike the retransmission timer, a backoff algorithm is not used.

LAN Network Interface Configuration Screens LAN Network Interface Configuration Fields Network segment size (bytes) (HP modifiable.) This field specifies the largest packet (including all data, protocol headers, and link level headers) that will be sent by the LAN device. The only reason for entering a value smaller than 1514 is to make better use of memory for those systems where it is known that upper layer services will always send shorter messages.
LAN Network Interface Configuration Screens LAN Network Interface Configuration Load network directory mapping? (Y/N) If you have non-HP nodes on the LAN (nodes that do not support either ARP or probe protocols,) you must enter these nodes into the network directory and set load network directory mapping to Y. HP recommends the default unless non-HP nodes are on the LAN and the network directory has been configured. Refer to Chapter 15, “Network Directory,” for information about the network directory.
LAN Network Interface Configuration Screens Protocol Configuration Protocol Configuration The Protocol Configuration screen (#113) in Figure 5-4 is displayed when you press the [Go To PROTOCOL] function key at the LAN Network Interface Configuration screen (Figure 5-3).

LAN Network Interface Configuration Screens Probe Protocol Configuration Fields Proxy enabled (Y/N) Proxy nodes exist on LANs to provide node name and address mapping facilities for nodes that do not have local network directories. Proxy requests are multicast on the LAN to request information about a third-party node from a proxy node. Y means this node may be a proxy server and to answer all proxy requests on the LAN. N means this node will ignore all proxy requests on the LAN.
LAN Network Interface Configuration Screens Probe Protocol Configuration Proxy requests retransmission timeout (seconds) The time interval in seconds that the probe protocol will wait for a reply before attempting to retransmit a proxy request. The value should be set sufficiently large to avoid retransmissions in a temporarily overloaded environment, yet small enough to get a timely failure report when failure is inevitable.

14 Logging Configuration Screens The screens in this chapter are those you would see when configuring logging. The Logging Configuration branch of NMMGR begins with a screen called the Netxport Log Configuration screen. Figure 14-1 shows the screen flow for configuring the logging screens. Screens unique to logging are indicated by bold boxed screens. [FUNCTION] denotes the function key used at a screen to invoke the next screen on the screen flow.
Logging Configuration Screens Logging is configured for the purpose of recording events such as errors and console commands. You configure logging for each of the network subsystems and links. 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).

15 Network Directory 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 15-1 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 request for an internet address from the proxy server. For backup 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.
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 15-2 is the first screen displayed when you run NMMGR.
