Detect Dual WAN in use

[Maverickcdn]

Put a couple mins in searching but couldn't find the exact answer. I can locate how to detect which WAN is primary (wan0_primary=1) but...

How to check if Dual WAN is enabled (either native or DualWAN failover script) in nvram? assuming its wans_dualwan but what are the specific values for enabled vs disabled (wan none)?

TIA

I believe the contents of that variable is an array of per-interface values:

Thank you, suppose Ill just make the script logic

[ "$(nvram get wans_dualwan)" != 'wan none' ] && dual_wan='enabled'

When I have dual wan on it says both are connected. When I have wan fail over on it shows primary as connected and secondary as hot failover or cold failover if it doesn’t have an ip

That is currently part of what I do in the Dual WAN Failover is reading that nvram value. Specifically the second value being none, the first one can be wan lan or usb I believe.
