1_All the chosen wired connections are detected failed
Sams as back up mode, you have to choose at least one WAN port. If there are are multiple WAN ports
chosen, the system will transfer traffic to 3G/3.5G USB dongles when all the chosen wired connections are
detected failed.
2_Bandwidth of the chosen wired network is over the pre-defined threshold
After you decide which WAN ports needs 3G/3.5G dongle backup, the system will enable the bandwidth
threshold configuration as the red column shows.
You can decide 3G/3.5G USB dongle backup when WAN port is disconnected as well as 3G/3.5G dongle load
balance.
Must click the box first to enable the bandwidth threshold configuration.
(1)Set Threshold to start load balance:
The following figure uses 10000Kbits as threshold, which means that if the system detects the bandwidth
of WAN1 is over 10000 Kbits, 3G/3.5G USB dongle will start the load balance.
(2)Set Threshold to stop load balance:
Observing the daily bandwith usage, you can find that bandwidth usage is dynamic. If you already set
bandwidth thresholds for load balance, we recommend that you could set the limit for bandwidth
threshold to lower the USB port sensibility and avoide high frequency of enabling or disabling 3G/3.5G USB.
