The Point-to-Point Configuration screen (#44) in Figure 7-2 “Point-to-Point Link Configuration
Screen” 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 Chapter 5 “Introductory Screens” for information on the Network Transport
Configuration screen. Figure 7-2 Point-to-Point Link Configuration
Screen

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. 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. Move to the Link Name
field. Enter a link name 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.) 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. Tab to the Speed field.
Enter the line transmission speed of this link. Tab to the Type field.
Enter DD for direct dial, SD
for shared dial or DC for direct
connection. Press the [Save Data] key to record
the data you have entered. 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." 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) name
Display only. - 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 LAN network; the node
portion must be unique for all nodes on a LAN
network.
There
are two methods of entering an internet protocol (IP) address within
NMMGR: Enter the fully qualified IP address
(for example, Class C, C 192.191.191 009). OR 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: 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.mmm.mmm 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 NS 3000/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 NS 3000/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

- IP subnet mask
An IP subnet mask is specified in the same format
as an IP address. 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 “Networking Concepts” for details on deriving an 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.
