Along with other protocol information, the Dial ID Protocol Configuration screen (#103) provides a means of verifying that the remote node is indeed the intended remote node and that both local and remote nodes have proper security access. This screen, shown in Figure 10-6 "Dial ID Protocol Configuration Screen", is displayed when you press the [Go To DIAL] function key at the Protocol Configuration screen (Figure 10-4 "Protocol Configuration Screen"). It is also displayed when you type the path name:

@NETXPORT.NI.NIname.PROTOCOL.DIAL

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

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

Maximum retransmissions per packet

(HP modifiable.) This is the maximum number of times that a dial ID protocol packet will be retransmitted. If the expected response to a packet is not received after this number of retransmissions, the link device it is using is closed. This value is related to the retransmission timeout.

Multiplying these values results in the total time that passes before a failure is reported (an error message will be recorded). HP recommends that you alter this value only upon the recommendation of your HP representative. However, note that if the value is set too low, dial connections may fail unnecessarily when response times are temporarily slowed by transient conditions such as an abnormally high volume of traffic. The higher the value, the longer it will take to be notified of a link failure if one occurs.

Default value: 2

Range: 1-10

Retransmission timeout (secs)

(HP modifiable.) The retransmission timeout is the time interval that passes between retransmissions of a dial ID protocol packet. Multiplying the values configured for maximum number of retransmissions per packet (described above) and retransmission timeout results in the total time that passes before a failure is reported (an error message will be recorded). HP recommends that you alter this value only upon the recommendation of your HP representative. However, note that if the value is set too low, dial connections may fail unnecessarily when response times are temporarily slowed by transient conditions such as an abnormally high volume of traffic. The higher the value, the longer it will take to be notified of a link failure if one occurs.

Default value: 5

Range: 1-10

Security on (Y/N)

A Y (Yes) value in this field indicates that security strings are to be exchanged and validated between the node being configured and a remote node.

When a dial connection is initiated by a remote node, the security string sent by the remote node is checked against the list of valid security strings configured for the dial ID protocol for this network interface. (See Related screens). When a dial connection is initiated by this node, the local dial ID protocol sends the destination's security string (as configured on this node) to that node. (Related screens, indicates the path name of the screen in which you can configure security strings.) If security validation fails, an error message is logged. (Refer to the NS 3000/iX Error Messages Reference Manual for a description of any error message received.)
