Usage Guidelines

The ntp-service in-interface disable command provides a method for access control.

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. By default, all the interfaces can receive NTP packets after NTP is enabled on the device. However, an unreliable clock source makes NTP clock data inaccurate.
  • The NTP clock data are modified when the interface is attacked maliciously.

Example

# Disable VLANIF100 from receiving NTP packets.

<Huawei> system-view
[Huawei] interface vlanif 100
