The IP Protocol Configuration screen (#156) in Figure 5-5 “IP Protocol Configuration Screen” is displayed when you press the [Go To IP] function key at the Protocol Configuration screen (Figure 5-4 “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
LAN 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 named 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 modifying. 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 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. HP recommends
that you use 20 as the store-and-forward buffers. Consult your HP representative
before modifying this value.
You do not need to allocate store-and-forward buffers if you
are configuring a non-gateway node on this network. Leave the default
(0) in this field to indicate that this is a non-gateway node.
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 bits of the network portion of an address
and where xxx is a value ranging from 000 to 255, representing
the node portion of the 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 zeroes or all ones are not
allowed. These are special values.
Default value: No default, but a value must be
supplied.
- IP subnet mask (optional)
An IP subnet mask is used when configuring subnetworks.
The mask identifies which bits of an IP address will be used to
define a subnetwork. 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.
For example, a mask for a Class A network with the subnet field
being the first eight bits of the node part would be expressed as
255 255.000.000. The default is no IP subnet mask.
Refer to the HP e3000/iX Network Planning and Configuration
Guide for more details on subnets.
