What impact does the order of the interfaces have in the Network->Interfaces list?  If Network->Failover defines the priority order of use what does the order in the Network->Interfaces do?

Hello,

Thank you for contacting Teltonika Crowd Support.

Kindly be advised that ordering interfaces in Network - > Interfaces list will enable you to specify the primary WAN interface. A WAN interface that is higher on the list will have a higher priority than the ones that are lower, i.e., the device will always use the WAN interface with the highest priority as long as it is available. If the primary WAN interface goes down, the device will start using the WAN interface with the second highest priority and so on. The same applies when ordering interfaces in Network - > Failover. It is important to note that changing the WAN interface order in Network - > Interfaces will also change the interface order in Network - > Failover and vice versa.

The major differences between Network - > Interfaces and Network - > Failover are as described below:

1. When failover is disabled, the WAN interface selected as the primary WAN interface in Network - > Interfaces will be used as the primary WAN interface for as long as it is active (status showing "Running" in green) regardless of whether the WAN interface has internet access or not. A secondary WAN interface will only be used once the primary WAN interface goes down (status showing "Stopped" in red). This is not the case when failover is enabled as the failover feature does not only check whether the primary WAN interface is active (status showing "Running" in green) but also checks whether a specific host is reachable via the primary WAN interface. By default, failover uses google DNS server (8.8.8.8) to check whether an interface has internet access. If the primary WAN interface is active (status showing "Running" in green) but does not have internet access, the router will then switch to a failover interface which will have the second highest priority under Network - > Failover.

2. When failover is enabled on interfaces that are under Network - > Failover, only WAN interfaces with failover enabled will take part in providing secondary WAN connectivity when the primary WAN interface goes down or does not have internet access. The selection of the secondary WAN interface will be based on the interface priority. However when failover is disabled, all active WAN interfaces will take part in provision of secondary WAN connectivity based on their position in Network - > Interfaces list.

Warm regards

Wesley

Thanks for that.  I could not find any explanation like that in the manuals.
