NTP servers
You can configure one or more NTP (Network Time Protocol) servers to allow clock
synchronization with all computers on the same network as the transmitter. To view the
AUI’s
NTP Servers
page (see Figure 2.123), select
NTP Servers
from the
User Settings
options.
There are several functions available on this page - enabling NTP, monitoring NTP server
status and managing servers.
Figure 2.123: User Settings - NTP Servers
Enabling NTP
Enable the NTP function by selecting the
Enable NTP
checkbox. Disable by de-selecting the
Enable NTP
checkbox. Press the
Apply
button to activate any change.
Note:
The accuracy of the NTP synchronization is related to the distance to the server,
therefore Nautel recommends you choose servers in the same country as the equipment.
If this is not possible, attempt to connect to servers from the same continent.
Note:
The NTP clock synchronization polling interval varies between 64 and 1024 seconds.
To minimize network traffic, the interval will change depending on how much error
is accumulated between polling events and will be increased if the remote NTP server
becomes unreachable. The polling interval is also randomized slightly to avoid the
situation where a large number of requests are always arriving at the NTP server at
the same time.
