RT-AC87U LACP (802.3ad) Link aggregation possible?

[NightsEvil]

I have recently flashed the most recent available merlin firmware (380.68_0) to my ASUS RT-AC87U router and was wondering if there was finally a way to use LACP in conjuncture with my SG-200 Cisco switch and Qnap TS-653PRO nas for better throughput.

I had read some info here: https://github.com/RMerl/asuswrt-merlin/wiki/Link-Aggregation
But was not sure if this would work on my device, any advice?

LACP work fine in last stock firmware 3.0.0.4.382.50702 ONLY between Lan2-3-4 ports, between Lan1-2 only static mode
