The ntp-service manycast-client command enables the NTP manycast client mode.
The undo ntp-service manycast-client command disables the NTP manycast client configuration.
By default, the manycast client service is disabled.

Usage Scenario
An interface can be specified on the local device and used to send NTP manycast messages after a timeout period elapses. The local device runs in manycast client mode and periodically sends manycast messages to a manycast server. Based on the message sent by the manycast server, a dynamic client-server association is established.
In VS mode, this command is supported only by the admin VS.
Precautions
If this command is the first NTP configuration command, the system automatically adds the ntp-service [ ipv6 ] server disable command in the configuration file to disable the NTP service. To enable the NTP service, run the undo ntp-service [ ipv6 ] server disable command. If this command is the last NTP configuration command to be deleted, the system automatically deletes the ntp-service [ ipv6 ] server disable command from the configuration file.
