The Address Resolution Protocol (ARP) Configuration screen (#111) in Figure 8-6 "Address Resolution Protocol (ARP) Configuration Screen" is displayed when you press the [Go To ARP] function key at the Protocol Configuration screen (Figure 8-4 "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 Token Ring NI.

[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 Token Ring 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.

Default value: 1

Range: 1-10
