Disabling a Specified Interface from Receiving NTP Packets
Context
You can disable the interface connected
to external devices from receiving NTP packets in the following scenarios:
- An unreliable clock server exists on the interface. After the NTP functions are enabled, all interfaces can receive NTP packets by default. However, an unreliable clock source makes NTP clock data inaccurate.
- The NTP clock data are modified when the interface is attacked maliciously.
