Both (see below)

That's a typo on my part.

I've seem something similar to this before, where a port-channel 
wouldn't come up between a Cisco IOS and IOS-XR box if one end was 
"switchport trunk" and the other "switchport access". This confused me 
slightly - I didn't know LACP was aware of the trunk/access nature of 
the "upper" interface.
