mwan3 with NCM (+virtual interface) tracking issue #16966

Open mydogteddy opened 3 years ago

mydogteddy commented 3 years ago

I am not sure if this is known, I have been configuring mwan3. I have an Huawei cpe pro 2 router connected to the WAN port of a Belkin-3200.

I use mwan3 in the Belkin-3200 and have created a fall-over to an Huawei E3372s dongle working in NCM mode

The Huawei E3372s creates 2 interfaces named in my case HuaweiNCM which I have defined however the Belkin-3200 when using the Huawei E3372s creates another virtual interface which it names as HuaweiNCM_4

I have found the only way to get this working properly is to include both interfaces in the members and then to include both of these members into the policy.

I could not get this to work without including the virtual interface in members etc.

I don't know if this is the correct way to configure this but as far as I can tell it's the only way.

I believe this is a generic problem of mwan3 handling those automatic virtual interfaces

Further advice would be gratefully received.

same happens to me, i put a cron to restart mwan3 10 mins after reboot, which brings wwan back to online, but after wwan dhcp expires, if it doesn't get it renewed in time, it sometimes goes back to disabled.
