III-2-3. BASIC SETTINGS – SYSTEM TIME
The System Time represents the date and time. The system uptime defines the passing time after the
system boots up. There is no battery on the switch and hence the system time cannot be saved in the
system. Users can configure the time zone and system time manually by synchronizing the time with the
browser or by enabling the “NTP” service to get the time from a NTP Server.
NTP
Network Time Protocol (NTP) is a clock synchronization protocol, which is used to synchronize the
system time with the NTP server. NTP is one of the oldest Internet Protocols in use from 1985 until now.
It works based on a client-server model, but it can also be used in peer-to-peer relationships. The NTP
application on the switch is follows the client-server model and the switch plays a role in the NTP Client.
