NTP Configuration

1.4.1 Configuration Prerequisites
NTP authentication configuration involves:
z Configuring NTP authentication on the client
z Configuring NTP authentication on the server
Observe the following principles when configuring NTP authentication:
z If the NTP authentication function is not enabled on the client, the client can be
synchronized to a server no matter whether the NTP authentication function is
enabled on the server (assuming that other related configurations are performed).
z You need to couple the NTP authentication with a trusted key.
z Configurations on the server and the client must be consistent.
z The client with the NTP authentication function enabled is only synchronized to the
server that provides a trusted key.
