1th Chapter ntp1.1 NTP IntroductionNTP, Network Time Protocol, is a protocol that is used to synchronize the time of each computer in a network. Its purpose is to synchronize the computer clock to the World coordinated UTC, its accuracy in the LAN up to 0.1ms, in most places on the Internet its accuracy can reach 1-50ms.1.2 NTP server-side deployment1.2.1Environm

It provides high-accuracy time correction (less than 1 milliseconds on LAN versus standard, dozens of MS on WAN)Typically, time synchronization occurs as follows:(1): The NTP client issues a Time request packet (UDP packet) to the

settings. 3. Cisco Equipment If you want to sync the Cisco device's time, you can use the following command in global configuration mode. The code is as follows: # NTP server The NTP-enabled device from other manufacturers has its own parameters for network time. If you want to sync the device with the
dedicated port of 123. Over time, the computer clock tends to drift. Network Time Protocol (NTP) is a way to ensure that your clock remains accurate. It provides a time synchronization mechanism between routers, switches, workstation and servers. NTP server is often used in IT system environments with time synchronization requirements.

ObjectiveNTP, Network Time Protocol, is a protocol that is used to synchronize the time of each computer in a network. The consistency and accuracy of time is important, whether it is a private computer or a server cluster that is built at work.
