Usage Guidelines

Usage Scenario

A local device automatically runs as a broadcast client once it is configured to receive NTP broadcast messages on a current interface.

If a device is configured to send NTP broadcast packets through an existing interface, the local device automatically runs a broadcast server to transmit broadcast messages periodically to broadcast clients.

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.
