Cisco Endorsed by Nilo Noguera. Roberto Salazar about 9 years 1 month ago. non-blocking refers to the the port's access to the backplane or the line card's ASIC interface to the ports.When a line card is sadi to be non-blocking it usually means that for all it's ports it has full b/w to the backplane.In some line card, due to h/w designed are said to be blocking line card or over-subscribed.his usually means that for x number of ports it shares an interface to the ASIC hence does not have full b/w access to the backplane. some example of a blocking or (oversubscribed) line card are WS-X4418-GB, WS-X4448-GB and there are some 6500 line cards that escapes my mind right now.
