Abstract
(EN) A method ,system and apparatus for preventing from counterfeiting the MAC address, in which after certification apparatus receives the source MAC address and the access port information relating to the certification request sent from access apparatus, it judges whether the source MAC address has been counterfeited; if so, have a corresponding process to it. The present invention don’t need that the access apparatus distributes the MAC address to every access port in order to reduce the system workload. At the same time, when the user modifies the access port or source MAC address, it don’t need that the access apparatus reconfigures the MAC address so as to save the system workload, reduce the user operation and tend to the service development.
(FR) L’invention concerne un procédé, un système et un appareil visant à empêcher la contrefaçon d’une adresse MAC. Selon l’invention, après avoir reçu une adresse MAC source et des informations d’accès de port associées à une demande de certification envoyée par un appareil d’accès, un appareil de certification détermine si l’adresse MAC source a été contrefaite ; le cas échéant, celle-ci fait l’objet d’un traitement approprié. L’invention ne nécessite pas la transmission de l’adresse MAC par l’appareil d’accès à chaque port d’accès, ce qui permet de réduire la charge de travail du système. De plus, lorsqu’un utilisateur modifie le port d’accès ou l’adresse MAC source, l’invention ne nécessite pas que l’appareil d’accès reconfigure l’adresse MAC, ce qui permet de réduire là encore la charge de travail du système, de minimiser l’intervention de l’utilisateur et de favoriser le développer des services.
(ZH) 本发明公开了一种防止MAC地址仿冒的方法,在认证设备收到接入设备发来的与认证请求相关的源MAC地址和接入端口信息后,判断该源MAC地址是否存在MAC地址仿冒,若存在,则对其进行相应的处理。本发明同时公开了一种防止MAC地址仿冒的系统、接入设备和认证设备。本发明无需接入设备对每个接入端口进行MAC地址分配,减少了系统工作量;同时,在用户更改接入端口或源MAC地址时,也无需接入设备重新配置MAC地址,在节省系统工作量的同时,简化了用户操作,方便了业务开展。
