undo ntp-service broadcast-client
View
VLAN interface view
Parameter
None.
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 Switch to receive NTP broadcast messages and
operate in broadcast client mode. The local 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 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 via Vlan-Interface1.
