6. Configure the following time (SNTP) server properties:

Synchronization
Mode
Select the frequency in which the Segment Controller is
synchronized to the SNTP server:
•
Automatic. The Segment Controller 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 Segment Controller
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 Segment
Controller is synchronized is based on the value in the
Synchronization Interval property. This option can only
be used for Ethernet connections.
• Disabled. The Segment Controller is not synchronized with
the SNTP server.
Time
Synchronization

the SNTP server. This option is only available if Fixed

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
Segment Controller, 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.
