Configuring NTP Multicast Mode
The multicast server periodically sends NTP multicast messages to multicast clients, which send replies
after receiving the messages and synchronize their local clocks.
For devices working in the multicast mode, you need to configure both the server and clients. The NTP
multicast mode must be configured in the specific interface view.
