Configuring Optional Parameters of NTP

Specifying the Source Interface for NTP Messages
If you specify the source interface for NTP messages, the device sets the source IP address of the NTP
messages as the primary IP address of the specified interface when sending the NTP messages.
When the device responds to an NTP request received, the source IP address of the NTP response is
always the IP address of the interface that received the NTP request.
