5.3.4.6 Restart NTP
The following screen appears after clicking on the Restart NTP function:
Restarting NTP Services is the only possibility of making NTP changes effective without having
to restart the entire Module 8029NTC. As you can see at the warning message, the currently
reachable stability and accuracy are lost due to this restart.
After a restart of the NTP service it takes a few minutes until the NTP service on Module
8029NTC is adjusted on an available NTP Server again.
5.3.4.7 Access Restrictions / Configuring the NTP Service Restrictions
One of the extended configuration options for NTP is the "Access Restrictions" (NTP access
restrictions).
Restrictions are used in order to control access to the System’s NTP service and these are
regrettably the most misunderstood options of the NTP configuration.
If you are not familiar with these options, a detailed explanation can be found at
