The Gatehalf Configuration screen (#40) in Figure 9-2 “Gatehalf Configuration Screen” 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 Chapter 5 “Introductory Screens” for information
on the Network Transport Configuration screen. Figure 9-2 Gatehalf Configuration Screen

In the Partner's IP address
field, enter the internet protocol (IP) address of this gateway
half's partner. 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. 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. Tab down to the Link name
field and enter a link name to represent each individual hardware
interface card. Tab over to the Link type
field. Enter DD for direct dial
or DC for leased lines, private
lines, or other non-switched links. Enter the physical path of this node's Programmable
Serial Interface (PSI) card. 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. If this is a dial link, enter the phone number ofthis gateway half's partner. 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. Press the [Save Data] key. Proceed
to Chapter 10 “Validating 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] 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 address
This is the internet protocol (IP) address of the
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 subnet mask
Allows you to specify the subnet mask of this gateway
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 “Networking Concepts” - 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 “Configuring an X.25 Node”
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.
