No authentication key is configured to be trusted by default.
Examples
# Enable NTP authentication, specify to use MD5 encryption algorithm, with the key ID of 37 and key
value of BetterKey.
<Sysname> system-view

Default level
2: System level
Parameters
interface-type interface-number: Specifies an interface by its interface type and interface number.
Description
Use the ntp-service source-interface command to specify the source interface for NTP messages.
Use the undo ntp-service source-interface command to restore the default.
By default, no source interface is specified for NTP messages, and the system uses the IP address of the
interface determined by the matched route as the source IP address of NTP messages.
If you do not wish the IP address of a certain interface on the local device to become the destination
address of response messages, you can use this command to specify the source interface for NTP
messages, so that the source IP address in NTP messages is the primary IP address of this interface.
Examples
# Specify the source interface of NTP messages as GE0/1.
<Sysname> system-view
[Sysname] ntp-service source-interface gigabitethernet 0/1
