not the preferred one.
This command sets the remote server specified by X.X.X.X or server-name as the local
time server. The X.X.X.X is a host address and cannot be the IP address of the
broadcast, multicast or reference clock. In this configuration, the local device can
synchronize to the remote server but not the vice versa.
Example
# Configure the local device to synchronize to the server at 128.108.22.44. NTP version
3 is used.
