Abstract
A method, an apparatus, and a system for controlling access of a user terminal, where the method includes receiving, by a controller, an authentication packet sent by an access switching node through an established data tunnel; obtaining, by the controller, a source media access control (MAC) address of the authentication packet; after access authentication implemented on a user terminal, determining, from a maintained correspondence between MAC addresses of user terminals and interface identifiers, an interface identifier corresponding to the MAC address of the successfully-authenticated user terminal, where the interface identifier identifies an interface connected to the user terminal; and sending, by the controller, the determined interface identifier to the access switching node through an established control tunnel, and instructing the access switching node to enable the interface corresponding to the interface identifier.
