Notification on failover

Installing and Using OpenWrt Network and Wireless Configuration

I've got failover working and mwan3.user is being invoked but only on ifup, ifdown, connected and disconnected.

So right now when "wan" goes down I get a disconnected but when there is no ACTION when the failover to "wanb" occurs.

So is there an ACTION when a failover actually happens and I just missed it?

Switching to wanb happens right when you see ACTION=disconnected (no additional actions are logged).

You can check the current status using mwan3 policies and
iptables -t mangle -nvL mwan3_policy_<policy_name> .

The active interface in the policy should change as well as the firewall mark in the iptables rule.

Thanks for the explanation!
