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. 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
other network interface names of the node being configured (except gatehalf
or loopback networks). 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 of this 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 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, FDDI,
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 number corresponds to the slot location
of a node's programmable serial interface (PSI) card or,
Advanced Communication Controller (ACC) for N 4000 and
A500 systems. Recommended slot locations and physical path calculations
vary according to the type of HP e3000 system you are running. For the various platforms, physical path syntax (examples
only) look like: Series 9x7: | 48 | PSI | Series 9x8: | 56/44 | PSI | Series 9x9: | 10/4/16 | PSI | Series 99x: | 0/28/12 | PSI | Series N 4000: | 1/10/0/1.7 | ACC | Series A500: | 0/2/0/1.4 | ACC |
If you are unsure of the slot location or of the physical path
number to configure for your system, run the offline ODE MAPPER
utility, see your system documentation, or consult your Hewlett-Packard service
representative. - Transmission speed
The line transmission speed is given in bits per
second. For direct connect the value, must be supported by both adapter
and 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.
