Mwan3 on switches

Installing and Using OpenWrt

Hi,

mwan3 docs give example configs for "eth" devices but on switches it looks different.
The actual switch I want to use mwan3 on is Zyxel GS1900-10HP. Its ifconfig output looks like this (abbreviated):

How can I use mwan3 in that way, that two ports (e.g. lan2/lan3 or lan9/lan10) are used as two WAN ports for mwan3?
Does somebody have an example configuration for mwan3 on switches?

Issue is that the mwan3 docs say that a physical port must be used. And I don't have space left for full GUI. Hence the docs are not clear.

You can use the following how-to to split ports:
