Parameter
X.X.X.X
: Multicast IP address, which is a Class D address.
Description
Using the
ntp-service multicast-client
command, you can configure the NTP
multicast client mode. Using the
undo ntp-service multicast-client
command,
you can remove the NTP multicast client mode.
By default, no multicast client service is configured and the X.X.X.X is
224.0.1.1.
This command is used to specify an interface on the local device to receive the
NTP multicast packets. The local device is run in client mode. It first listens
discreetly to the multicast packets from the server. When the first multicast
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 (multicast-client) mode to listen discreetly to the
multicast packets and synchronize the local clock according to the coming
multicast packets.
