Configuring NTP Multicast Mode

For switches 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 switches working
in the NTP multicast client mode will respond to the NTP messages, so as to start the clock
synchronization.
An H3C S5600 series Ethernet switch can work as a multicast server or a multicast client.
A multicast server can synchronize multicast clients only after its clock has been synchronized.
An S5600 series switch working in the multicast server mode supports up to 1,024 multicast clients.
