Methods, system and apparatus to protect network virtual local control in Ethernet network in a ring. The present invention relates to a method, system and apparatus for protecting a network virtual local control in a network in Ethernet ring.The method comprises: in a process to create a field of Ethernet automatic protection switching (EAPs) devices we defined as nodes of the Ethernet network provide a way to process messages received in the VLAN control according to the additional information in a The message of the protocol, which can be used to distinguish between different types of messages of the protocol.And then open the function of routing of doors in a ring inside the VLAN control.According to the present invention, when a field is created, the occurrence of broadcast storm and the phenomenon of packet loss is prevented by taking a series of measures, such as closing the function of routing ports in the ring within the VLAN control protocol messages, and a Ecebu00edveis are established to control the VLAN.In such a way that messages protocol are not processed, and therefore, the normal operation of the VLAN control is ensured after opening the function of routing of the doors in the ring within the VLAN control.
