keyid: The key ID carried in the messages transmitted to the multicast clients, which 

is in the range of 1 to 4294967295.

 

ttl: Defines the Time-To-Live (TTL) period of multicast packets.

number: NTP version number in the range of 1 to 3.

 

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.

 

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.
