The Address Resolution Protocol (ARP) Configuration screen
(#111) in Figure 9-6 "Address Resolution
Protocol (ARP) Configuration Screen" is displayed when you press the
[Go To ARP] function key at the Protocol Configuration screen
(Figure 9-4 "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 FDDI NI.
Figure 9-6 Address Resolution Protocol (ARP) Configuration Screen
This screen allows you to configure the information required for the address
resolution protocol (ARP). The ARP protocol exists on a FDDI network to provide
a means of exchanging addressing information between nodes.
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 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. 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.
