Configuring and Managing the SmartServer
8. Configure the following time (SNTP) server properties:
Property
Time Server Port
The port used by the SmartServer to receive time data. This default value
is 123, and it cannot be changed. Contact your IS 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. You have four choices:
Automatic. The SmartServer is synchronized every 1 to 15 minutes
and remains within 100ms 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.
