<p>The present invention discloses a method and an apparatus for maintaining the saved information of the node in an Ethernet ring network, wherein when a protection switching request on a non-virtual channel sub-ring needs to be eliminated, the node on the non-virtual channel sub-ring deletes the node saved information in all ports on the non-virtual channel sub-ring of the current node, and does not save the received node saved information in the no-request protocol frame. The method and apparatus of the present invention solve the problem that the address table can not be updated properly when the non-virtual channel sub-ring switches back.</p> |
