Abstract
A method and apparatus is provided for preventing the counterfeiting of a network-side Media Access Control (MAC) address. The method includes: receiving a message from a user equipment (UE) and resolving the message from the UE in order to obtain a MAC address of the UE; learning the MAC address of the UE if the MAC address of the UE is different from a known MAC address of a network-side equipment; learning the MAC address of the network-side equipment; and generating a MAC address learning table by utilizing the learned MAC address of the network-side equipment and setting the MAC address learning table to be a static address table, and/or filtering messages having source MAC addresses being the MAC address of the network-side equipment and from other user-side ports by utilizing the learned MAC address of the network-side equipment.
