The FDDI Configuration screen (#201) in Figure 6-4 “FDDI Configuration Screen” is displayed when you press the [Config Network]
key at the Network Transport Configuration screen (#42) with an
NI type of 7 (FDDI). Refer to 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 FDDI card for which you
are configuring a link. This name must be unique to the node.
Tab down to the field called Physical Path of FDDI Device Adapter.
Enter the physical path number corresponding to the SPU slot number
where the FDDI device adapter is located.
Press the [Save Data] key to save the
FDDI link configuration. If you need to identify neighbor gateways,
press the [Neighbor Gateways] key and proceed to
the section in the chapter called "To Identify Neighbor
Gateways." Otherwise, 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] 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 FDDI network; the node
portion must be unique for all nodes on a FDDI
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.

- 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 the IP address comprise the network and subnetwork
portion.
- Link name
The link name can have up to eight alphanumeric
characters and the first character must be alphabetic.
- Physical Path of FDDI Device Adapter
The physical path number corresponds to the slot
location of a node's FDDI device adapter. 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.
