This model switch only supports Static LAG

If your bonded NAS ports are configures as LACP ( sometimes called "Active") LAG, they are not compatible standards and a loop will form, causing network loss

Also, since your EERO and PC have only a single 1gig port to the switch, there is very little benefit in enabling LAG to the NAS, your other devices simply wont be able to take advantage of the aggregated bandwidth
