Internet protocol information must be supplied for each configured NI. The key field in the IP Protocol Configuration screen (#156) shown in is the IP internet address, which is used in IP routing and datagram delivery algorithms. Data in the other fields are used for internal resource allocation and performance tuning. The IP Protocol Configuration screen is displayed when you press the function key for [Go To IP] at the Protocol Configuration screen (Figure 6-4 "Protocol Configuration Screen"). It is also displayed when you type the path name:

@NETXPORT.NI.NIname.PROTOCOL.IP

in the Command window of any screen and press the [Enter] key, where NIname is a configured point-to-point NI.

Press the [Save Data] function key to transfer the data displayed on the screen to the configuration file you are creating or updating. Verify that the data record has been created by checking that the Data flag is set to Y.

Fields

Store & forward buffers

This field allocates buffers to support store-and-forward over the network interface being configured. You do not need to allocate store-and-forward buffers if you are configuring a non-gateway node on this network. You must allocate store and forward buffers if you are configuring an internet gateway and packets from another network will be forwarded over this network interface. You can modify the number of store-and-forward buffers to allow performance tuning for different network types. However, HP recommends that you use 20 as the store-and-forward buffers. Consult your HP representative before modifying this value.

If store-and-forward is to be disallowed, set this number to 0.

Default value: 0

Range: 0-50

NOTE: If this is a gateway node, HP recommends that you use 20 as the store-and-forward buffers.

IP internet address

Enter the internet protocol (IP) address for the network interface being configured.

There are two methods of entering an internet protocol (IP) address within NMMGR:

  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.

Addresses are made up of a network portion and a node portion. The supported classes of network addresses have the following forms:
Class C:

C nnn.nnn.nnn xxx

Class B:

B nnn.nnn xxx.xxx

Class A:

A nnn xxx.xxx.xxx

where xxx is a value ranging from 000 to 255, representing the node portion of the address and nnn is a value ranging from 000 to 255, representing eight bits of the network portion of an address. Note the network and node values of all zeros or all ones are not allowed. These are special value. The leftmost group of nnn has the following ranges for each address class:
Class C:

192-223

Class B:

128-191

Class A:

001-126

Default value: None

IP subnet mask

The IP subnet mask masks a portion of the IP address for subnets. The subnet is specified in the same format as an IP address; that is, the 32-bit mask is grouped in octets expressed as decimal integers and delimited by a "." or a space. for example, a mask for a class A address with the subnet field being the first 8 bits of the node portion would be expressed as 255 255.000.000. The defaul is no IP mask.

Refer to the HP e3000/iX Netowrk Planning and Configuration Guide for more details on subnets.
