Displaying And Maintaining Ntp - HP 5820X Switch Configuration Manual

NOTE:
After you enable the NTP authentication feature for the client, make sure that you configure for the
client an authentication key that is the same as on the server and specify that the authentication key is
trusted. Otherwise, the client cannot be synchronized to the server.
