This operational-state field reports the actual current state UCS Manager has observed for this FC monitoring session, as opposed to what was administratively requested. For an FC SPAN-style traffic-monitoring session that copies frames from a source port or VSAN to a designated analyzer port, this is the value a monitoring dashboard would poll to detect that the connection has actually gone down (for example a link failure), even if the admin state still says it should be up. A healthy instance normally reads 'up' or 'online'; if the cable behind this specific port is unplugged, this value would flip to something like 'link-down' within seconds.
