The Address Resolution Protocol (ARP) Configuration screen
(#111) in Figure 5-7 “Address Resolution Protocol (ARP)
Configuration Screen” is displayed
when you press the [Go To ARP] 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.ARP
in the command window of any screen and press the [Enter]
key, where NIname is a configured LAN NI.

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 as described.
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 (seconds)
This is the time interval (in seconds) between 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
