Description
Using the ntp-service broadcast-client command, you can configure the NTP
broadcast client mode. Using the undo ntp-service broadcast-client
command, you can remove the NTP broadcast client mode.
By default, no NTP broadcast client service is configured.
This command is used to specify the local interface on the local device to
receive the NTP broadcast packets. The local device is run in client mode. It
first listens discreetly to the broadcast packets from the server. When the first
broadcast packet is received, the local device enables a short client/server
mode to exchange messages with the remote server in order to estimate
network delay. Then it enters the client mode to listen discreetly to the
broadcast packets and synchronize the local clock according to the coming
broadcast packets.
Example
Enable the interface Ethernet 1/0/1 to receive NTP broadcast message.
[NEC-PHILIPS] interface ethernet 1/0/1
[NEC-PHILIPS-Ethernet1/0/1] ntp-service broadcast-client
