6. Configure the following time (SNTP) server properties:
Time Server Port The port used by the SmartServer to receive time data. The
default value is 123, and it cannot be changed. Contact your IT
department to make sure that your firewall is configured to
allow you to access the time server on this port.
Time
Synchronization
Mode
Select the frequency in which the SmartServer is synchronized
to the SNTP server:
• Automatic. The SmartServer is synchronized every 1 to 15
minutes and remains within 100 ms of the SNTP server.
This is the default, and it can be used for both LAN and dial-
out (modem and GPRS) connections.
• Sync when Dial-Up is active. The SmartServer clock is
synchronized when a dial-out connection is established. This
option can only be used for dial-out connections (modem and
GPRS).
• Fixed Interval. The frequency in which the SmartServer is
synchronized is based on the value in the Synchronization
Interval property. This option can only be used for Ethernet
connections.
• Disabled. The SmartServer is not synchronized with the
SNTP server.
Time
Synchronization
Interval
Set how often the SmartServer clock is synchronized with the
SNTP server. This option is only available if Fixed Interval is
the selected synchronization method. The default
synchronization interval is 12 hours.
Use As Select whether this time server is the Default or the Backup
time server. If this is the first time service created on the
SmartServer, this option is set to Default. If another time
service is currently designated as the default and you select
Default, the default designation will be removed from the other
time server when you click Submit.
