Internet Protocol Configuration  

Internet protocol information must be supplied for each configured NI.
The key field in the IP Protocol Configuration screen (#156) shown below
in figure 6-5 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).  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 that network and node
                          values of all zeroes or all ones are not
                          allowed.  These are special values.  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 default is no IP mask.

                          Refer to the HP 3000/iX Network Planning and 
                          Configuration Guide for more details on
                          subnets.
