DGS-3620-28PC:admin#
76-15 config ntp trusted_key
Description
This command is used to specify the key ID which is trusted for the purposes of authenticating
peers with symmetric key cryptography.
If authentication is enabled, use this command to define one or more key numbers (corresponding
to the keys defined with the ntp authentication-key command) that a peer NTP system must
provide in its NTP packets, in order for this system to synchronize to it. This function provides
protection against accidentally synchronizing the system to a system that is not trusted, because
the other system must know the correct authentication key.
