DGS-3610 Series Configuration Guide Chapter 23 NTP Configuration
23.2.6 Enabling/Disabling NTP Function
The function of command no ntp is to disable the NTP synchronization service, stop the
time synchronization, and clear relevant information of NTP configuration.
The NTP function is disabled by default, but may be enabled as long as the NTP server or
NTP security authentication mechanism is configured.
To disable the NTP, run the following commands in the global configuration mode:
Disable the NTP function.
ntp authenticate
or
ntp server ip-addr [version
version][ source if-name number][key
keyid][prefer]
23.2.7 Configuring Real Time
Synchronization for NTP
For higher accuracy, the interaction of eight messages will be completed consecutively
between the client and server during the first synchronization. In subsequent
synchronization, the time interval of NTP synchronization is one minute, that is, from the end
of this synchronization to the automatic initiation of next clock synchronization. When the
users want to implement real time synchronization manually, this command can be used.
To implement NTP real time synchronization, run the following commands in the global
configuration mode:
Enable real time synchronization.
Disable real time synchronization.
DGS-3610 series client system is set to conduct next synchronization in 30 minutes after the
completion of each synchronization. Real time synchronization will be triggered when new
servers are added and when the NTP clients stop synchronization. There is no effect to use
the command during synchronization.
Both the command to disable real time synchronization and the command to disable the
NTP can stop the clock synchronization (during the synchronization) or disable the clock
synchronization (between processes of synchronization). The difference is that the latter can
not only disable the NTP synchronization function, but also clear relevant NTP configuration
information.
