Configure a Point-to-Point Network Interface

1. 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.

2. 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.

3. Move to the Link Name field. Enter a link name to represent the Point-to-Point card for which you are configuring a link. This name must be unique to both the node and the network interface (NI). Up to 40 network links are supported per Point-to-Point (router) NI. (Up to eight network links are supported per screen. To configure additional links, save the current screen and then clear the screen to add additional links.)

4. Tab down to the Physical Path field. Enter the physical path number corresponding to the SPU slot number of the programmable serial interface (PSI) card, or slot and part of advanced communication controller (ACC) card.

5. Tab to the Speed field. Enter the line transmission speed of this link.

6. Tab to the Type field. Enter DD for direct dial, SD for shared dial or DC for direct connection.

7. Tab to the Card Type field. Enter LAPBMUX if ACC adapter is being used, or LAPB for a PSI adapter. Do not mix both Card Types under the same NI.

8. Press the [Save Data] key to record the data you have entered.

9. If you need to identify neighbor gateways, press the [Neighbor Gateways] key and proceed to the section in this chapter called "To Configure Neighbor Gateways."

10. If you have already configured neighbor gateways for this link or your network contains no neighbor gateways, press the [Link Routing] key and proceed to the section in this chapter titled "To Configure Node Mapping."

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

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.

1. Enter the fully qualified IP address (for example, Class C, C 192.191.191 009).

   OR

2. 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.

Card Type

Specify LAPB if the adapter card used for this link is a single port PSI adapter. Specify LAPBMUX if this link is using one port on a multi-port synchronous MUX adapter card (ACC).

Note: Card types cannot be mixed on the same NI.

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.

Link Name

The link name can have up to eight alphanumeric characters and the first character must be alphabetic.

Physical Path

The physical path number corresponds to the slot location of a node's programmable serial interface (PSI) card, and LAPBMUX card (ACC). 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:	1/10/0/1.7
Series A500:	0/2/0/1.4

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.

Speed

The line transmission speed is given in bits per second. For direct connect the value, must be supported by the cable. Values are 1200, 2400, 4800, 9600, 19200, 38400, 56000, and 64000. The default is 56000.

Type

Enter DD (direct dial) if you always want to call the same host over a dial link. If you choose DD the remote host does not have to be adjacent and other nodes can be accessed through the remote host. Enter SD if you want to call more than one adjacent remote node over a dial link without reconfiguring. If you choose SD, no other remote nodes can be accessed through the remote host; it is an end point in the connection. Enter DC if the link is a leased line, private line, or other non-switched link.
