SNTP authentication mode must be set to enabled for SNTP authentication to occur between the SNTP client and server. When the mode is set to enable, the SNTP client authenticates with the SNTP server before synchronization occurs. When the mode is set to disable, no authentication is performed on SNTP communications. SNTP authentication is set to disabled by default.
Use the set sntp authentication mode command to enable SNTP authentication on the SNTP client.
This example shows how to enable SNTP authentication mode:
System(rw)->set sntp authentication mode enable
