The ntp-service authentication enable command enables identity authentication for NTP.
The undo ntp-service authentication enable command disables identity authentication.
By default, identity authentication is disabled.
Usage Scenario
Identity authentication in NTP applies to a network requiring high security.
Precautions
If this command is the first NTP configuration command, the system automatically adds the ntp-service [ ipv6 ] server disable command in the configuration file to disable the NTP service. To enable the NTP service, run the undo ntp-service [ ipv6 ] server disable command. If this command is the last NTP configuration command to be deleted, the system automatically deletes the ntp-service [ ipv6 ] server disable command from the configuration file.
