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 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 [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.
