Will JunOS show the ae as down, then?

[channel-group N mode on] with IOS just enables portchanneling unconditionally.
Wouldn't that, in conjunction with a JunOS without an "lacp" stanza
under the ifd / interface stanza (lacp passive) work just fine? I've
mostly only been doing JunOS-JunOS LACP lately, though I've done it
quite a bit with Cisco-Cisco in the past.

LACP is worth running on your links if it works, IMO.

Maybe try setting active on the JunOS and Cisco sides?
