Description This command specifies the interface to receive NTP broadcast packets. Operating in
broadcast client mode, the device listens to broadcast packets from the server. When
receiving the first broadcast packet, it first enters a transient client/server model to
exchange messages with the remote server in order to estimate network delay. Then it
enters the client mode to listen to the broadcast packets and synchronizes the local
clock according to the received broadcast packets.
