■ Internal GPS – The source of time is the internal GPS. In this case only RipEX Time zone
and Daylight saving parameters below are active.
○ Source IP
Default = empty
IP address of the NTP server, which provides Time source. Date and Time will be requested by
RipEX from there. More NTP servers can be configured, the more servers, the better time accur-
acy. If the Time source is a RipEX over Radio channel, only one source server is recommended,
since the Radio channel could be overloaded.
○ Minimum polling interval
List box: 1min to 2h 17min
RipEX polls the source server in order to synchronize itself in the set period or later.
○ RipEX Time zone
Select RipEX Time zone from list box.
Default = (GMT +1:00) Central Europe
This time zone is used for conversion of internal Unix epoch time to "human readable date&time"
in RipEX logs..
○ Daylight saving
List box: On, Off
Default = On
If
On , Daylight saving is activated according the respective rules for selected RipEX Time zone.
• RipEX NTP server
Information about the status of internal NTP server in the RipEX
○
State
■ not synced - not synchronized
■ synced to GPS - synchronized to internal GPS
■ synced to NTP - synchronized to NTP server
○ Stratum
1 to 16 (1=the best, 16=the worst, 8=when internal time in RipEX is set manually)
The stratum represents the quality and accuracy of time, which the NTP server provides.
○ Delay [ms] This is the delay of packet (1/2 round trip time), which RipEX received from the NTP
server while asked for synchronization. This delay is compensated in the RipEX NTP server.
○ Jitter [ms]
The Jitter of received times when RipEX asked for time synchronization from NTP server(s).
SNMP
You can read more about SNMP in RipEX (MIB table description incl.) in Application note "RipEX SNMP
Configuration Guide" here: http://www.racom.eu/eng/products/m/ripex/app/snmp.html
List box: On, Off
Default = Off
If On , RipEX works as a standard SNMP agent. i.e. it responds to "SNMP GET Request" packets re-
ceived from even several SNMP managers on any of its IP addresses. It transmits SNMP traps as per
its configuration (Settings/Device/Alarm management or Routing/Backup).
• Community name
Default = public
