Abstract
A method, system and controlling bridge (CB) for acquiring port extension (PE) topology information, and a method and system for processing an upstream port, wherein, the method for acquiring the port extension (PE) topology information includes: a CB receiving a link layer discovery protocol (LLDP) message sent by the PE, and perceiving an attachment of the PE; the CB receiving Extended Port Create message sent by the PE, and instantiating corresponding instantiated ports inside the CB. By adopting the above-mentioned technical scheme, the topology information of the PE connected to the CB can be obtained and a channel for forwarding data can be established, effectively.
