Both the NTP server and the NTP client must be enabled with NTP authentication and configured with the same authentication key, and the authentication key must be declared as reliable on the client side. Otherwise, NTP authentication will fail.
NTP client synchronizes to authenticated NTP servers to ensure that time service is reliable across the network. You must enable NTP authentication, and then configure basic NTP functions and specify the authentication key. Otherwise, the NTP authentication fails.
The system view is displayed.
NTP authentication is enabled.
The NTP authentication key is configured.
As the Secure Hash Algorithm 256 (HMAC-SHA256) algorithm provides higher security than the Message-Digest Algorithm 5 (MD5) algorithm, using the HMAC-SHA256 algorithm for NTP authentication is recommended.
The device that wants to synchronize its clock should declare its key as reliable.
When the client synchronizes to authenticated server, the authentication key must be declared as reliable only on the client side.
The configuration is committed.
