HP e3000/iX Network Planning and Configuration Guide (36922-90037)

Chapter 8 141
Configuring an X.25 Node
To Configure an X.25 Network Interface
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:
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.
NOTE To obtain a class B or C IP address, contact Government Systems,
Incorporated (GSI). To obtain an application form, write GSI at the
address below. Allow at least eight working days for GSI to process an
IP address request.
