The NTP Server Edit window displays. Enter the required information:
Host: The IP address for the server to be used as host.
Min Poll Interval: Select a value from the drop down (the default is 3 (8s)).
Max Poll Interval: Select a value from the drop down (the default is 3 (8s)).
For both NTP Peers, and NTP Servers the Minimum and Maximum Poll rate
for NTP packets can be configured.
Both NTP Peers and NTP Servers support either manually configured Sym-
metric Key- ID/Key string pairs or the use of Auto- Key. However, these
choices are mutually exclusive and must be identically configured on both the
VersaSync and the NTP Peer or NTP Server. If the Symmetric Key-ID/Key
string pair method is selected the Key-ID must be first defined on the Sym-
metric Key page.
Enable Symmetric Key: Click to enable Symmetric Key, and then select an
option from the drop down menu that displays.
Note: Before you can choose an option in the Key field, you
must first set up symmetric keys through the Actions panel.
See "Configuring NTP Symmetric Keys" on page120 . Con-
versely, you may check the Autokey box below the Key field.
Enable Autokey: Click here if you want to use Autokey with this server. See
"NTP Autokey" on page115.
Note: When you configure NTP Autokey, you must first disable
the NTP service in the NTP Services panel, and then re-enable
it after the Autokey configuration is completed.
Enable Burst: This tells NTP to send a burst to the remote server when the
server is reachable.
Enable Iburst: The iburst function tells NTP to send a burst of queries instead
of one when the remote server is not reachable for faster clock syn-
chronization. This will occur if the connection was interrupted, or upon restart
of the NTP daemon. For additional information, please refer to public NTP
configuration documentation.
Mark as Preferred: Click here to make this server the preferred server. For
more information, see "Configuring "NTP Stratum 1" Operation" on
page106.
