Telling which ethernet a user is connected?

Say I have 2 pppoe servers on 2 ethernets… On winbox, I see the users sorted in a tree… Like this:

--- --- --- and so on... So, it's pretty easy to tell which ethernet they are connected to... But what I need is a command I can use that tells me the same information via console... I need to get this result via ssh...

“ppp active print detail” tells me alot of stuff, but not the ethernet :cry:

this would be useful for me too
