- The nebula switch enables RSTP to prevent a loop in the ring topology by default. If your topology is a ring topology, one of the ports will be blocked by RSTP. If the ring topology is not your expected topology, please check your connections.
- If you set LACP but the connecting device hasn’t set LACP, Nebula will show blocking on the dashboard. Please set LACP on the connecting device.
