The ntp-service broadcast-client command configures the device to work in NTP broadcast client mode.
The undo ntp-service broadcast-client command removes the device from the NTP broadcast client mode.
By default, the device is not configured in the NTP broadcast client mode.
On a synchronization subnet, when the IP address of a server or a symmetric peer is not determined, or when the clocks on a large number of devices need to be synchronized on the network, you can implement clock synchronization by configuring the broadcast mode.
On a specified interface on the broadcast client, run the ntp-service broadcast-client command to configure an interface on the local device to receive NTP broadcast packets. When the local device automatically runs in the broadcast client mode, the device can receive the synchronization packets sent by a broadcast server. For the configuration of the broadcast server, see the ntp-service broadcast-server command.
When the configuration is complete, you can run the display ntp-service sessions command to obtain information about sessions between the broadcast server and the local device.
