The IP Protocol Configuration screen (#156) in Figure 7-10 “IP Protocol Configuration Screen” is displayed when you press the [Go To IP] function key at the Protocol Configuration screen (Figure 7-4 “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
X.25 NI.
This screen is used to supply IP protocol information for
the network being configured. Each NI has an IP address. The IP
Address field is a key element in IP routing and datagram delivery
algorithms. The IP subnet mask field allows you to identify an IP
subnet mask for the NI names in the path. The store and forward
buffers field is useful for internal resource allocation and performance
tuning.
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.
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:
001-126
Network and node values of all zeros or all ones are not allowed.
These are special values.
Default value: None, but a value must be
supplied.
- 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 default is no IP mask.
Refer to the HP e3000/iX Network Planning and Configuration
Guide for more details on subnets.
