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.

ttl-number: The TTL period of multicast packets, which is in the range of 1 to 255.

version: Defines an NTP version.

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

Description

Using the ntp-servicemulticast-servercommand, you can enable the NTP multicast server mode. Using the undo ntp-servicemulticast-servercommand, 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.
