Description
Use the ntp-service broadcast-client command to configure NTP broadcast
client mode.
Use the undo ntp-service broadcast-client command to disable the NTP
broadcast client mode.
By default, the NTP broadcast client mode is disabled.
Designate an interface on the local Ethernet Switch to receive NTP broadcast
messages and operate in broadcast client mode. The local Ethernet Switch listens
to the broadcast from the server. When it receives the first broadcast packet, it
starts a brief Client/Server mode to switch messages with a remote server for
estimating the network delay. Thereafter, the local Ethernet Switch enters
Broadcast Client mode and continues listening to the broadcast and synchronizes
the local clock according to the arrived broadcast message.
Example
# Configure to receive NTP broadcast packets through Vlan-Interface1.
