NTP client
In server mode: NTP transmits the time in multicast or broadcast.
To add an NTP synchronisation source, follow these steps:
1) TIME menu > NTP > NTP client:
2) Add an NTP server

by clicking on
, and the following window will appear:
1
Enter the NTP address of the NTP client.
2
Poll interval: this is the period of time, in seconds, between two queries. The value shown in the NTP configuration
status table (see previous page) will be lower than the minimum value in order to enable quick
synchronisation.
Once synchronisation is complete, this value will increase in order to reduce network traffic and load on the time
servers.

3 (8 seconds) to 17 (36 hours 24 minutes and 32 seconds).

Enable and select a pre-defined symmetric key. See Chapter
4.5.2 NTP synchronisation
.
4
Before enabling this parameter, enter the autokey. See Chapter
4.5.2 NTP synchronisation
.
5
The Burst option should be enabled when the server can be reached. It activates the sending of 8 packets with
an interval of 16 seconds between the first and the second, then two seconds for the rest. This option improves
the stability of exchanges.
6
The iBurst option can be used to synchronise the server more quickly as soon as it starts up.
this option is recommended, as it enables the rapid provision of an active NTP service.
7
This parameter takes stratum N-1 servers as a reference base. This value can apply to a reference source such
as GPS. If this option is ticked for Netsilon, the user believes that this server is stable and nearby, and that it
serves as a priority reference.
1
The limit is set at a maximum of 5 NTP servers.
