SNTP Mode
Select the synchronization mode from the drop-down list. The following types of
synchronization are possible:
–
Listen
With this mode, the device is passive and receives SNTP frames that deliver the time
of day. Settings in the input boxes "SNTP Server Address" and "SNTP Server Port"
have no effect in this mode.
In this mode, only IPv4 addresses are supported.
–
Poll
If you select this mode, the input box "Poll Interval[s]" is displayed to allow further
configuration. In this mode, the settings in the input boxes "SNTP Server Address"
and "SNTP Server Port" are taken into account. With this type of synchronization, the
device is active and sends a time query to the SNTP server.
In this mode, IPv4 and IPv6 addresses are supported.
●
Poll Interval[s]
Here, enter the interval between two time queries. In this box, you enter the query interval
in seconds. Possible values are 16 to 16284 seconds.
●
SNTP Server Address
Enter the IP address or the FQDN (Fully Qualified Domain Name) of the SNTP server.
●
SNTP Server Port
Enter the port of the SNTP server.
The following ports are possible:
–
123 (standard port)
–
1025 to 36564
●
Primary
The check mark is set for the SNTP server that you create first. If several SNTP servers
have been created, the primary server is queried first.
