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 12-6 “Dial ID Protocol Configuration Screen”, is displayed when
you press the [Go To DIAL] function key at the
Protocol Configuration screen (Figure 12-4 “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.)
