To Configure a Point-to-Point Network Interface The Point-to-Point Configuration screen (#44) in figure 7-2 is displayed when you press the [Config Network] key at the Network Transport Configuration screen (#42) with an NI type of 2 (point-to-point). Refer to page 5-9 for information on the Network Transport Configuration screen.Figure 7-2. Point-to-Point Link 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. Move to the Link Name field. Enter a linkname to represent the point-to-point card for which you are configuring a link. This name must be unique to both the node and the network interface (NI). Up to 40 network links are supported per point-to-point (router) NI. (Up to eight network links are supported per screen. To configure additional links, save the current screen and then clear the screen to add additional links.|) 4. Tab down to the Physical Path field. Enter the physical path number corresponding to the SPU slot number of the programmable serial interface (PSI) card. 5. Tab to the Speed field. Enter the line transmission speed of this link. 6. Tab to the Type field. Enter DD for direct dial, SD for shared dial or DC for direct connection. 7. Press the [Save Data] key to record the data you have entered. 8. If you need to identify neighbor gateways, press the [Neighbor Gateways] key and proceed to the section in this chapter called "To Configure Neighbor Gateways." 9. If you have already configured neighbor gateways for this link or your network contains no neighbor gateways, press the [Link Routing] key and proceed to the section in this chapter titled "To Configure Node Mapping." 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 point-to-point network; the node portion must be unique for all nodes on a point-to-point 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 more information on deriving the IP subnet mask. Link Name The link name can have up to eight alphanumeric characters and the first character must be alphabetic. Physical Path The physical path number corresponds to the slot location of a node's programmable serial interface (PSI) 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. Speed The line transmission speed is given in bits per second. For direct connect the value, must be supported by the cable. Values are 1200, 2400, 4800, 9600, 19200, 38400, 56000, and 64000. The default is 56000. Type Enter DD (direct dial) if you always want to call the same host over a dial link. If you choose DD the remote host does not have to be adjacent and other nodes can be accessed through the remote host. Enter SD if you want to call more than one adjacent remote node over a dial link without reconfiguring. If you choose SD, no other remote nodes can be accessed through the remote host; it is an end point in the connection. Enter DC if the link is a leased line, private line, or other non-switched link.
