To Configure a LAN Network Interface The LAN Configuration screen (#41) in figure 6-2 is displayed when you press the [Config Network] key at the Network Transport Configuration screen (#42) with an NI type of 1 (LAN). Refer to page 5-9 for information on the Network Transport Configuration screen.Figure 6-2. LAN Configuration Screen Steps 1. In the IP address field, enter the internet protocol (IP) address for the node being configured. An example of an address is: C 192.191.191 009. 2. The IP subnet mask is optional. If entering one, tab to the IP subnet mask field and enter the number in the same format as an IP address. 3. The proxy node is optional. Enter Y only if your network has internetworks (networks with gateways) or non-HP nodes and you are not using domain name services. 4. Move to the Link name field. Enter a link name to represent the LAN card for which you are configuring a link. This name must be unique to the node. 5. Tab down to the field called Physical path of LANIC. Enter the physical path number corresponding to the SPU slot number where the LAN interface controller card is located. 6. Tab down to the field called Enable Ethernet (Y/N). By default, ethernet is enabled. Change the field to N if you do not want ethernet enabled. 7. Tab down to field called Enable IEEE802.3 (Y/N). By default, IEEE802.3 is enabled. Change the field to N if you do not want IEEE802.3 enabled. 8. Press the [Save Data] key to save the LAN link configuration. If you need to identify neighbor gateways, press the [Neighbor Gateways] key and proceed to the section in this chapter called "To Identify Neighbor Gateways." Otherwise, proceed to chapter 10 titled "Validating the Network Transport and Cross-Validating with SYSGEN" and press the [Validate Netxport] key. Optional Keys Press the [List NIs] key to list the names and types of already configured network interfaces. Press the [Delete NI] key to remove a configured network interface from the configuration file. Press the [Read Other NI] key to call up a previously configured Network Interface name. Fields. Node name Display only. Network interface (NI) Display only. name IP address The IP address is an address of a node on a network. An IP address has two parts: a network portion and a node portion. The network portion must be the same for all nodes on a LAN network; the node portion must be unique for all nodes on a LAN network. There are two methods of entering an internet protocol (IP) address within NMMGR: 1. Enter the fully qualified IP address (for example, Class C, C 192.191.191 009) OR 2. Enter only the network (nnn) and node (xxx) portions of the IP address as four positive integers between 0 and 255 separated by periods or blanks (for example, 15.123.44.98). You need not enter the following items as NMMGR will fill these in: - Class A, B, C - Leading zeros for the network and node portion of the IP address. HP assigns the network portion (initial nine digits) of IP addresses from ARPA Class C, though your addresses may also be of Classes A or B. The complete formats are: Class A nnn xxx.xxx.xxx B nnn.nnn xxx.xxx C nnn.nnn.nnn xxx Where : nnn = the network portion of the IP address and xxx = the node portion of the IP address. For Class C, the node portion of the IP address must be between 001 and 254. If you are adding your NS3000/iX node to an existing network, the network portion of each node's IP address should be the same. You will have to find out what this is, and use it in the network portion of the IP address of your NS3000/iX node. Also, you will need to know the node portions of the IP addresses of each of the nodes (usually they will be numbered sequentially, such as 001, 002, and so on), so that you can specify a unique node portion for the IP address of your node. If you have a network map, it should provide a record of such items as the node name and IP address of each node. If there is no record, and if you want to find out each node's IP address, you will have to issue the following command (NM capability required) on each of the nodes: NETCONTROL NET=NIname;STATUS One of the lines of output from this command tells you what the complete IP address is for that node; the last three digits are the unique node portion of the class C address. ______________________________________________ NOTE To obtain a class B or C IP address, contact Government Systems, Incorporated (GSI). To obtain an application form, write GSI at the address below. Allow at least eight working days for GSI to process an IP address request. Government Systems, Inc.

The 32-bit mask is grouped in octets expressed as decimal integers and delimited by either a period (.) or a space. An IP mask is used when configuring subnetworks. The mask identifies which bits of an IP address will be used to define a subnetwork. To determine these bits, you first need to estimate how many subnetworks and nodes per subnetwork you need. See chapter 2 for details on deriving an IP subnet mask. Proxy node Establishing a proxy node is a way of placing node name and address mapping information in a single location. If you are configuring an internetwork or a network with non-HP nodes, it may be easier to update your configurations if you have them located in a central place, that is, the proxy node. On an internetwork, the proxy node is usually a gateway. (It is not necessary to configure a proxy node if you have configured domain names. See chapter 12 for information on domain names.) Link name The link name can have up to eight alphanumeric characters and the first character must be alphabetic. Physical Path of LANIC The physical path number corresponds to the slot location of a node's local area network interface controller (LANIC) card. Recommended slot locations and physical path calculations vary according to the type of HP 3000 system you are running. If you are unsure of the slot location or of the physical path number to configure for your system, see your system documentation or consult your Hewlett-Packard service representative. Enable Ethernet? A Y in this field enables ethernet for the LAN. You can enable either ethernet or IEEE802.3 or both simultaneously. One or the other must be enabled (both fields may not be set to N). Ethernet is enabled by default. Disabling Ethernet has the effect of disabling the ARP protocol as well and you will need to handle name to IP address resolution by other means. Enable IEEE802.3? A Y in this field enables IEEE802.3 for the LAN. You can enable either IEEE802.3 or ethernet or both simultaneously. One or the other must be enabled (both fields may not be set to N). IEEE802.3 is enabled by default. Disabling IEEE802.3 has the effect of disabling the probe protocol as well and you will need to handle name to IP address resolution by other means.
