○ Manual – Values can be set manually.
■ Hello packet period [s]
Default = 60 sec, [Max=3600]
When the set period expires, the next Hello packet is transmitted. To avoid the collisions,
there is a jitter of approx. 5%.
■ Hello packet success rate [%]
List box: possible values
Default = 87.5
When a lower percentage of Hello packets than set has been delivered to the counterpart,
the unit switches to the next alternative gateway in the line. (The info about successfully
delivered outbound Hello packets are carried by received Hello packets)
■ RSS [-dBm]
Default = Off [255= Off]
Hello packets carry the info about average RSS (saved in respective Statistic table) on each
radio hop on its way. When any RSS on the way is lower than the set one, the unit switches
to the next alternative gateway in the line. Each individual packet is evaluated.
■ Test when lower priority
Note: This menu item has been renamed to improve understanding. It read "Lower priority
path checking" until FW ver. 1.4.x.x. Its functionality has NOT been changed.
List box: On/Off
Default = On
If On, the alternative path is tested, even if it is lower priority than the currently active one
(Hello packets are transmitted). Advantage – if the active path fails, system switches only to
a functional alternative. Disadvantage – when e.g. GSM for backup is used, Hello packets
used for testing are charged. When Off, the respective alternative path is tested only when
its priority is higher than that of the active path.
Note 1: the number of Backup paths is not limited. The number of Alternative routes is min.2 and max.
16 (active ones). There can be more than 16 Alternative routes defined, only the active ones are tested.
Note 2: When Optimization (Settings/Radio/Optimization) is “On”, UDP packets with both source and
destination port 8886 are not transferred over the network, they are discarded in the end RipEX. UDP
packets with source port 8903 are not optimized, even if Optimization is “On”.
Note 3: When SW key Backup routes or Master key expires, Backup path configuration is lost.
