Usage guidelines
In a network where there is a high security demand, the NTP authentication feature must be enabled for
a system running NTP. This feature enhances the network security by using client-server key authentication,
which prohibits a client from synchronizing to a device that has failed the authentication.
After you specify an NTP authentication key, use the ntp-service reliable authentication-keyid command
to configure the key as a trusted key. The key automatically changes to untrusted after you delete the key.
In this case, you do not need to execute the undo ntp-service reliable authentication-keyid command.
You can set a maximum of 128 keys by executing the command.
The authentication key, set in either plain text or cipher text, is saved to the configuration file in cipher
text.
Examples
# Set a plaintext MD5 authentication key, with the key ID of 10 and key value of BetterKey.
<Sysname> system-view
[Sysname] ntp-service authentication enable
[Sysname] ntp-service authentication-keyid 10 authentication-mode md5 simple BetterKey
