Network Time Protocol
Network Time Protocol (NTP) enables devices connected on local and worldwide networks to
synchronize their internal software and hardware clocks to the same time source. The IX20 device can
be configured as an NTP server, allowing downstream hosts that are attached to the device's Local
Area Networks to synchronize with the device.
When the device is configured as an NTP server, it also functions as an NTP client. The NTP client will
be consistently synchronized with one or more upstream NTP servers, which means that NTP packets
are transferred every few seconds. A minimum of one upstream NTP server is required. Additional
NTP servers can be configured. If multiple servers are configured, a number of time samples are
obtained from each of the servers and a subset of the NTP clock filter and selection algorithms are
applied to select the best of these.
See
Configure the device as an NTP server

server.
