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. 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, or slot and part of advanced communication controller (ACC)
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. Tab to the Card Type field. Enter LAPBMUX if ACC adapter is being used, or LAPB for a PSI adapter. Do not mix both Card Types under the same NI. 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.
There are two
methods of entering an internet protocol (IP) address within NMMGR: 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.
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.nnn.nnn 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. - Card Type
Specify LAPB if the adapter card used for this link
is a single port PSI adapter. Specify LAPBMUX if this link is using
one port on a multi-port synchronous MUX adapter card (ACC). Note: Card types cannot be mixed on the same NI. - 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,
and LAPBMUX card (ACC). 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 | Series 9x8: | 56/44 | Series 9x9: | 10/4/16 | Series 99x: | 0/28/12 | Series N4000: | 1/10/0/1.7 | Series A500: | 0/2/0/1.4 |
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. - 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.
