4.5.4.2 Disabling the NTP Service Function

Context
You can disable NTP services to prevent the device from being synchronized with the clock of
an external server or a symmetric peer, or when the device does not need to provide a clock
reference source for external clients.
The existing configuration is not deleted when the NTP service function is disabled.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
undo ntp-service enable
The NTP service function on the device is disabled.
By default, the NTP service function is enabled.
----End
Issue 01 (2014-11-30)
An unreliable clock server exists on the interface. After the NTP function is enabled, all
interfaces can receive NTP packets by default. However, an unreliable clock source makes
NTP clock data inaccurate.
The NTP clock data is modified when the interface is attacked maliciously.
