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.
Figure 6-2 LAN 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:
Class A, B, C
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.
