This table contains information about the VSF links. An VSF link is a logical interface for the connection between VSF member devices. To use an VSF link, you must bind at least one physical port to it. These ports are called 'VSF physical ports' or 'VSF Ports'. The physical ports assigned to an VSF link automatically form an aggregate VSF link. An VSF link goes down only if all of its members' physical ports are down.
