Configuring NTP Multicast Mode

For devices working in the multicast mode, you need to configure both the server and clients. The
multicast server periodically sends NTP multicast messages to multicast clients. The devices working in
the NTP multicast client mode will respond to the NTP messages, so as to start the clock
synchronization.
The device can work as a multicast server or a multicast client.
A multicast server can synchronize multicast clients only after its clock has been synchronized.
The device working in the multicast server mode supports up to 1,024 multicast clients.
