Failover & Failback
Auto failover/failback ensures always-online network connectivity. When primary WAN link (WAN1)
fails, all traffic will switch over to the backup WAN (WAN2) seamlessly.
Again, when the primary link is restored, traffic will be handled over from WAN2 to WAN1.
WAN Port Service Detection Policy
WAN1 (Primary): Choose a desired WAN as the primary WAN Link from the list.
WAN2 (Backup): Choose a desired WAN as the backup WAN Link from the list.
Keep Backup Interface Connected: Enable if want to keep the backup WAN (WAN2) interface
always connected to the Internet.
Connectivity Decision & Probe Cycle: Set a number of times and time in seconds to determine
when to switch to the backup link (WAN2) when primary link (WAN1) fails and vise versa.
Example, Auto failover takes place after straight 3 consecutive failures in every 30 seconds meaning
all traffic will hand over to backup link (WAN2) after primary link fails to response in total of 90 seconds,
30 seconds for 3 consecutive failures.
Note: Failover and Failback follow the same Connectivity Decision & Probe Cycle rule to failover from WAN1 to WAN2
or fallback from WAN2 to WAN1.
Failover/Fallback Rule Decisions:
1. Probe by Ping: Enable Ping to the gateway or an IP address
Gateway: Internal system will wait for responses to the pings from the gateway of the WAN.
Host: Internal system will wait for responses to the pings from a fixed IP address.
2. Probe by Signal Strength: Enable to measure the LTE signal strength
Minimum RSRP / RSSI: Set a minimum requirement for RSRP and RSSI for initiating
automatic WAN failback or failover procedures.
