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 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.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.
- 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 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
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 |
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.
