Internet Protocol Configuration  

Internet Protocol information must be supplied for each configured NI.
The key field in the IP Protocol Configuration screen (#156) shown in
figure 10-5 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 10-4).
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: 

                             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 nnn is a value ranging from 000 to 255,
                          representing eight bits of the network portion
                          of an address and 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

                          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.
