Internet Protocol information must be supplied for each configured
NI. The key field in the IP Protocol Configuration screen (#156)
shown in Figure 12-5 “IP Protocol Configuration Screen” is the IP internet
address, which is used in IP routing and datagram delivery algorithms.
The IP subnet mask field allows you to identify an IP subnet mask
for the NI named in the path. The store and forward buffers field
is useful for internal resource allocation and performance tuning.
The IP Protocol Configuration screen is displayed when you
press the [Go To IP] function key at the Protocol
Configuration screen (Figure 12-4 “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 gateway half
NI name.

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 node 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. Because you are configuring
a gateway half NI, enter the IP address of this gateway half's
partner gateway half. This is the IP address of the home network
for which the partner serves as a gateway half.
There are two methods of entering an internet protocol (IP)
address within NMMGR:
Enter the fully qualified IP address
(for example, Class C, C 192.191.191 009)
OR
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 nnn is a value ranging from 000
to 255, representing eight bit of the network portion of an address
and xxx is a value ranging from 000 to 255,
representing the node portion of an address.
The leftmost group of nnn has the following
ranges for each address class:
- Class C:
192-223
- Class B:
128-191
- Class A:
001-126x
Default value: None
- IP mask
The IP 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 default is no IP mask.
