The LAN Configuration screen (#41) in Figure 6-2 “LAN Configuration Screen” is
displayed when you press the [Config Network] key at the Network Transport Configuration screen (#42)
with an NI type of 1 (LAN). 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.
The proxy node is optional. Enter Y only if your network has internetworks (networks
with gateways) or non-HP nodes and you are not using domain name
services.
Move to the Link name field. Enter a link name to represent the LAN card
for which you are configuring a link. This name must be unique to the
node.
Move to the Link type field. Enter BT100 for a 100Base-T link, LAN for
a ThinLAN link, or VG100 LAN for a 100VG-AnyLAN link.
Tab down to the field called Physical path of LANIC. Enter the physical path number corresponding
to the SPU slot number where the LAN interface controller card is
located.
Tab down to the field called Enable Ethernet (Y/N). By default, ethernet is enabled. Change the field
to N if you do not want ethernet and
the ARP protocol enabled.
Tab down to field called Enable IEEE 802.3 (Y/N). By default, IEEE 802.3 is enabled. Change
the field to N if you do not want IEEE 802.3
and the Probe protocol enabled.
Press the [Save Data] key to save the LAN link configuration. If you need to
identify neighbor gateways, press the [Neighbor Gateways] key and proceed to the section in this 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 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.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 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.
- Proxy node
Establishing a proxy node is a way of placing node
name and address mapping information in a single location. If you
are configuring an internetwork or a network with non-HP nodes,
it may be easier to update your configurations if you have them
located in a central place, that is, the proxy node. On an internetwork, the
proxy node is usually a gateway. (It is not necessary to configure
a proxy node if you have configured domain names. See Chapter 12 “Configuring Domain Name Files” for information on domain names.)
- Link name
The link name can have up to eight alphanumeric
characters and the first character must be alphabetic.
- Physical Path of LANIC
The physical path number corresponds to the slot
location of a node's local area network interface controller
(LANIC) card. 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: | 1/10/0/0 |
Series A500: | 0/2/0/0 |
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.
- Enable Ethernet?
A Y in this field enables ethernet for the LAN. You
can enable either ethernet or IEEE 802.3 or both simultaneously. One
or the other must be enabled (both fields may not be set to N). Ethernet is enabled by default.
Disabling Ethernet has the effect of disabling the ARP protocol
and you will need to handle both name to IP and IP to station (MAC)
address resolution by other means.
- Enable IEEE 802.3?
A Y in this field enables IEEE 802.3 for the
LAN. You can enable either IEEE 802.3 or ethernet or both simultaneously.
One or the other must be enabled (both fields may not be set to N). IEEE 802.3 is enabled by default.
Disabling IEEE 802.3 has the effect of disabling
the probe protocol and you will need to handle both name to IP and
IP to station (MAC) address resolution by other means.
