I am trying to set up link aggregation to my Synology DS720+. I have the Synology set to Static Link Aggregation, and have ports 21 and 23 set as shown below. However, as soon as I plug in both cables, one goes straight to blocked. [Screenshot 2024-12-14 at 12.36.07]

Update - not sure it if is valid or cosmetic, but changing from MSTP to RSTP allowed both ports to show as up and not blocked. My Synology is up and reachable, but it is worth noting that it no longer shows up in the “Devices” list, or on the Map.

Link aggregation...am I doing something wrong?
