1.3.4 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 S3100-52P Ethernet switch can work as a multicast server or a multicast client.
