Configuring NTP Broadcast Mode

The broadcast server periodically sends NTP broadcast messages to the broadcast address

255.255.255.255. After receiving the messages, the AC working in NTP broadcast client mode sends a

reply and synchronizes its local clock.

For ACs working in the broadcast mode, you need to configure both the server and clients. Because an

interface needs to be specified on the broadcast server for sending NTP broadcast messages and an

interface also needs to be specified on each broadcast client for receiving broadcast messages, the

NTP broadcast mode can be configured only in the specific interface view.

A broadcast server can synchronize broadcast clients only after its clock has been synchronized.

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 ACs 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.
