Address Resolution Protocol (ARP) Configuration 

The Address Resolution Protocol (ARP) Config screen (#111) in figure 5-7
is displayed when you press the [Go To ARP] function key at the Protocol
configuration screen (figure 5-4).  It is also displayed when you type
the path name:

@NETXPORT.NI.NIname.PROTOCOL.ARP

in the command window of any screen and press the [Enter] key, where
NIname is a configured LAN NI.


          Figure 5-7.  Address Resolution Protocol (ARP) Config 

This screen allows you to configure the information required for the
address resolution protocol (ARP). The ARP protocol exists on an Ethernet
LAN network to provide a means of exchanging addressing information
between Ethernet nodes.  With the concurrent configuration of IEEE 802.3
and Ethernet, both the probe and ARP protocols broadcast requests to all
nodes on the LAN to resolve the LAN station address of a given remote
node.

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 

Retransmission maximum    This is the maximum number of times that an ARP
                          request packet will be retransmitted.  If an
                          ARP reply packet for this request is not
                          received after this number of retransmissions,
                          the attempted address resolution is considered
                          to have failed.  This value is bound closely to
                          the retransmission timeout value described
                          below.  Taken together, they represent the
                          total time to report an address resolution
                          failure.

                          In general, the value of this field should be
                          kept low.

                          Default value:  2

                          Range:  1-10

Retransmission timeout    This is the time interval (in seconds) between
(seconds)                 ARP retransmissions.  The value should be set
                          large enough to avoid retransmissions in a
                          temporarily overloaded environment, yet the
                          value should be small enough to receive a
                          timely failure report when a failure is
                          inevitable.

                          Default value:  1

                          Range:  1-10
