<p>The invention discloses a method and an apparatus for providing service for users with duplicate MAC address. The method comprises: step A: searching whether a learning entry having an address the same as a source MAC address exists in an MAC address table according to the source MAC address of an Ethernet data frame received from a user port, if yes, implementing step B, otherwise, carrying out normal learning and forwarding; step B: checking whether a replacement operation is carried out for the source MAC address in an MAC address replacement table, if the replacement operation is not completed, selecting an unused replacement entry in the MAC address table to replace the source MAC address and implementing step C; and if the replacement operation is completed, directly implementing the step C; and step C: forwarding the Ethernet data frame according to the replacement MAC address in the replacement entry. With the technical solutions provided in the present invention, the broadband access service still can be normally provided for users when two or more users have the same MAC.</p> |
