Abstract
Provided are a method and device for transmitting a packet. According to an example of the method, a Controlling Bridge (CB) device maintains a mapping entry representing a correspondence between a Port Extender (PEX) device and a Media Access Control (MAC) address of a host connected with the PEX device in a mapping table. The CB device receives a first data packet transmitted by a first PEX device, and determines a mapping entry in which the MAC address of the host matches a destination MAC address of the first data packet by querying the mapping table. Then, the CB device transmits the first data packet to a second PEX device in the mapping entry.
