To Configure a Token Ring Network Interface

The Token Ring Configuration screen (#49) in Figure 6-3 “Token Ring Configuration Screen” is displayed when you press the [Config Network] key at the Network Transport Configuration screen (#42) with an NI type of 6 (Token Ring). Refer to Chapter 5 “Introductory Screens” for information on the Network Transport Configuration screen.

Figure 6-3 Token Ring 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 Token Ring 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 Token Ring Device Adapter. Enter the physical path number corresponding to the SPU slot number where the Token Ring device adapter is located.
NOTE: If the same Token Ring card is being used for both NS and SNA communications, you must use the same value for this field as is configured for the SNA Link.
Press the [Save Data] key to save the Token Ring 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 Network Transport 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.

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.mmm.mmm 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.

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.

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.




	NOTE: If the same Token Ring card is being used for both NS and SNA communications, you must use the same name in this field as is configured for the SNA Link.

Physical Path of Device Adapter

The physical path number corresponds to the slot location of a node's device adapter. Recommended slot locations and physical path calculations vary according to the type of HP 3000 system you are running. If you are unsure of the slot location or of the physical path number to configure for your system, see your system documentation or consult your Hewlett-Packard service representative.
