Time Synchronization with SNTP

2.28 Time Synchronization with SNTP
EDS500 devices can synchronize date and time with a time server via the Simple Network
Time Protocol. This time information is used in Syslog messages and the internal log
(command <show log>).
The SNTP time can be used in timestamps by the telecontrol protocol IEC 60870-5-104.
After a synchronization the up-to-date time is displayed in the system overview (command
<show system>). If the time zone is set to cet-cest then winter and summer time are toggled
automatically; otherwise the displayed time is always winter time. Time is synchronized with
the server every 24 hours.
The default value for time zone is: cet.

If the synchronization with the time server should fail, a new attempt is started every minute.
The default value for all further synchronizations with the time server after the first successful
synchronization is: 24 hrs.
The interval between two synchronizations can be set by a command.

Monitor

The EDS500 devices support the monitoring of an IP address or IP route in respect to
reachability and existence. This can be achieved by the configuration of a so-called monitor
that can also be used to control the interfaces (Chapter 2.31, "IP Routing").
The IP address is periodically checked with an ICMP echo request (ping). If three successive
requests fail then the state of the monitor changes to not available. The first successful reply
rates the address as available again.
The monitor can also be used for the checking of a route the existence. Dynamic Montes are
usually handed by a routing protocol like RIP (refer to Chapter 2.31, "IP Routing")
