Before synchronizing, NTP compares the time reported by several network devices and does not synchronize
with one that is significantly different, even if it is a stratum 1.
The security features of NTP can be used to avoid the accidental or malicious setting of incorrect time. One such
mechanism is available: an encrypted authentication mechanism.
Though similar, the NTP algorithm is more complex and accurate than the Simple Network Time Protocol (SNTP).
IMPORTANT:
Enabling this feature results in synchronizing the system clock; therefore, it may affect
all sub-systems that rely on system time.
Commands
The following commands allow the user to configure NTP or show NTP configurations.
timesync ntp
This command is used to update the system clock using NTP.
Syntax
timesync ntp

Options
broadcast
Sets ntp client to operate in broadcast mode.
unicast
Sets ntp client to operate in unicast mode.
Usage
The default mode is broadcast.
[no] ntp
This command disables NTP and removes all NTP configurations on the device.
Syntax
[no] ntp [authentication
