S8000 Link Aggregation in LACP 802.3ad mode

Hi Everyone,

I have bought a S8000, because the switch is able to manage the link aggregation (announced in product description) but I'm not sure if the S8000 can support the LACP 802.3ad mode, I have connected my ReadyNas RN312 in mode LACP with layer 2+3, and I can't reach my NAS in this mode. I'm not able to check in which mode the S8000 is working when the  Link Aggregation :-(

1) How can I know if the S8000 supports or not the LACP?

2) Where can I find the enabled Link aggregation mode in the S8000 Web UI?

Thanks
