Configuring a LAN Node

Configure a LAN Network Interface

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.
