Usage Guidelines

Usage Scenario

When the clock of a device on the network needs to be synchronized in unicast server/client mode, the command can be run, and the remote server specified by ip-address is used as the local clock server. The local device runs in client mode. In this mode, the local client can be synchronized to the remote server, but the remote server cannot be synchronized to the local client.


# Configure the server to provide the synchronizing time for the local device. The NTP version number is 3.
