value: Specifies the MD5 authentication key string. If simple is specified, it is a string of 1 to 32
characters. If cipher is specified, it is a string of 1 to 73 characters.
Usage guidelines
You need to enable SNTP authentication in networks that require time synchronization security to make
sure SNTP clients are only synchronized to authenticated NTP servers.
Configure the same key ID and key value on the SNTP client and NTP server. Otherwise, the SNTP client
cannot be synchronized to the NTP server. After you configure an SNTP authentication key, use the sntp
reliable authentication-keyid command to set it 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 sntp-service reliable
authentication-keyid command.
You can set up to 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 an MD5 authentication key, with the key ID of 10 and key value of BetterKey. Input the key in plain
text.
<Sysname> system-view
[Sysname] sntp authentication enable
[Sysname] sntp authentication-keyid 10 authentication-mode md5 simple BetterKey
