USER GUIDE - Rev. 3 (January 2018)
•
Strict.
This option allows users to inhibit the accessibility test in the presence of
traffic. If the option is not activated, the test will only be executed when the period
of time indicated in
frequency
without traffic has passed. When the option is
enabled, the test will be performed regardless of whether traffic is present or not.
In the figure given as an example in the Ping Keep Alive configuration, connectivity
of the IP addresses 192.168.1.5 and 192.168.1.10 is verified every
15
minutes by
sending
2
ICMP packets of 29 bytes (28+
1
). In case of failure, the behaviour is
Single
and, in this case, if there is no response to the "Ping Test", the equipment
will be rebooted.
To prevent "Ping Test" failures occurring due to the simultaneous reception of
traffic, the equipment will check the activity through the WAN interface for 30
seconds prior to executing the "Ping Test". If the reception of traffic is detected,
the "Ping Test" function will not be executed.

Tunnel submenu
A tunnel can be defined as a virtual connection which emulates an end-to-end connection
between two nodes connected through a complex network, which may be public like
Internet or private.
To configure a tunnel, it is necessary to define the start and end points of the tunnel and the
traffic to be sent through it.
