Description
Use the ntp-service broadcast-client command to configure NTP broadcast client
mode.
Use the undo ntp-service broadcast-client command to disable NTP broadcast
client mode.
By default, the NTP broadcast client mode is disabled.
Designate an interface on the local device to receive NTP broadcast packets. The local
device operates in broadcast client mode. The local device listens to the broadcast
packets from the server. When it receives the first broadcast packet, it starts a brief
client/server mode to exchange messages with a remote server for estimating the
network delay. Thereafter, the local device enters broadcast client mode and continues
listening to the broadcast packets and synchronizes the local clock based on the
arrived broadcast packets.
