5.12 NTP/SNTP CONFIGURATION
The equipment has an NTP/SNTP client, meaning that it can synchronise time-related
information by accessing NTP servers. The NTP [3] protocol is a standard that is widely
used in TCP/IP-based networks. It admits the use of several NTP servers simultaneously,
and the option of using authentication.
The SNTP variant means a faster synchronization but less accurate and, on the other hand,
it is necessary to run it periodically.

The general usage parameters are:
• Enable. Enables/disables the execution of the NTP client. The client is operative
when the option is selected.
• Protocol. This sets whether the NTP or SNTP client is used.
• Authentication keys. Tabulate information allowing the definition of different
authentication codes to be used subsequently in communicating with the different
NTP servers.
The NTP client supports the configuration of multiple NTP servers to carry out
synchronization. Each has a set of customized parameters that determine the access
procedure:
