On a network that requires high security and runs the Network Time Protocol (NTP), enable the authentication function to prevent malicious attacks from changing the data of clock packets. Password authentication between NTP clients and servers can ensure that NTP clients synchronize time only with authenticated switches, improving network security.
Set the cipher-text key for HMAC-SHA256 authentication to xyz123 and specify the key as a trusted key.
