Description
Using the ntp-service multicast-server command, you can enable the NTP
multicast server mode. Using the undo ntp-service multicast-server command, you
can disable the NTP multicast server mode.
By default, no multicast service is configured, IP address is 224.0.1.1, and the version
number is 3.
With this command, you can specify an interface on the local device for sending NTP
multicast messages while the local device is running in multicast server mode to
periodically send multicast messages to its multicast clients.
Example
Enable the interface Ethernet 0 to send NTP multicast messages, given the multicast
group address is 224.0.1.1, key 4 is used for encryption, and NTP version number is
3.
