1. A packet forwarding control method, comprising:
determining a candidate core backbone (CB) set corresponding to a port extender (PE) device in accordance with a predetermined first selection rule by a CB when a plurality of CB devices are connected via horizontally cascaded ports within a virtual system to form a ring topology; and configuring first blocking entries corresponding to the respective PE device on the CB device upon determining the CB device belongs to the candidate CB set, and wherein the first blocking entries are for preventing the receiver-uncertain packets sent from the respective PE device being forwarded via designated horizontally cascaded ports.
