To Configure a Gatehalf Network Interface The Gatehalf Configuration screen (#40) in figure 9-2 is displayed when you press the [Config Network] key at the Network Transport Configuration screen (#42) with an NI type of 5 (Gateway Half). Refer to page 5-9 for information on the Network Transport Configuration screen.Figure 9-2. Gatehalf Configuration Screen Steps 1. In the Partner's IP address field, enter the internet protocol (IP) address of this gateway half's partner. 2. The IP subnet mask is optional. If entering one, tab down to the next field. In the IP subnet mask field, enter the number in the same format as an IP address. 3. Tab to the Home NI name field. Enter a name that is the same as one of the LAN, point-to-point, or X.25 network interface names of the node being configured. 4. Tab down to the Link name field and enter a link name to represent each individual hardware interface card. 5. Tab over to the Link type field. Enter DD for direct dialor DC for leased lines, private lines, or other non-switched links. 6. Enter the physical path of this node's Programmable Serial Interface (PSI) card. 7. Tab down to the next field. In the Transmission speed field, either leave the default or enter the transmission speed in bits per second as a number from 1200 to 64000. 8. If this is a dial link, enter the phone number of this gateway half's partner. 9. If this is a dial link, in the Security string field, either leave the default, or enter a value that HP nodes must use to gain dial link access to the node you are configuring. 10. Press the [Save Data] key. 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 Partner's IP This is the internet protocol (IP) address of the address node that will be the other half of the gateway half you are configuring. Enter the address in the same format as on the Point-to-Point Configuration screen. Partner's IP Allows you to specify the subnet mask of this gateway subnet mask half's partner gateway half. The 32-bit mask is grouped in octets expressed as decimal integers and delimited by either a period (.) or a space. 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. For details on deriving an IP subnet mask, see chapter 2. Home NI name The home NI name will be used by the software to determine which network address is the source network address when packets are sent over the gateway half. The home NI name cannot be either a gateway half or loopback NI name, but it can refer to any other type of network interface (LAN, token ring, point-to-point, or X.25 network interface). Link name Name that represents the hardware link. The link name can have up to eight alphanumeric characters; the first character must be alphabetic. The link name must be unique to both the node and the network. Link type The link type for a gateway half can be either DD for direct dial or DC for direct connect. Physical path The physical path of the gateway half's PSI card. See chapter 8 for information on the physical path. Transmission 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. Phone number Telephone number of this gateway half's partner gateway half. Enter the telephone number as a combination of decimal numbers (0 through 9), dashes, and the following special characters: / Separator used for automatic call units that have second dial-tone detect. E Optional end-of-number indicator. D Three-second delay (used for European modems and automatic call units that require built-in delays). # Defined by local phone system. * Defined by local phone system. Spaces, and left and right parentheses () are also allowed. To disable outbound dialing, enter an exclamation point (!) by itself in the phone number field. Security string This is a string containing up to eight alphanumeric characters, left justified, with no embedded blanks. The first character must be alphabetic. A value in this field is required if the remote (destination) node is an HP node (dial ID protocol is used). Remote HP nodes must use the security string to gain dial link access to the node you are configuring.
