I read this before in one of CiscoLive 
ISR not support LACP 

[Elliot Dierksen]

ISR 4K's definitely support LACP.

Hello!

ISR 4000 series routers do support LACP (at least on relatively modern IOS-XE software). Here is an example from my lab with an ISR 4331 router running IOS-XE 16.09.04 connected to a Catalyst 3850 switch using an LACP port-channel.
