NTP Client Configuration with IPv4 Address

NTP client, user can configure an association with a remote server. In this mode the client clock can synchronize to the remote server

After configuring the NTP servers, wait a few minutes before you verify that clock synchronization is successful. When the clock synchronization has actually happened, there will be an ‘*’ symbol along with the interface while you give the “show ntp peers” command.
