Dial ID Protocol Configuration
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
connection is closed.
This value is related to the retransmission timeout
value discussed.
Multiplying these values results in the total time that
passes before a failure is reported (an error message is
recorded when the timer expires). HP recommends that
you alter this value only upon the recommendation of
your HP representative. The higher the value, the
longer it will take to be notified of a link failure if one
occurs. The dial ID protocol is in use after the physical
and data link levels have been activated and before
normal communication 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. 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.
