Abstract
A method for creating a port group, includes generating, by a first software defined network (SDN) controller, the specified identifier according to a device identifier of a first forwarding device in a preset path, a device identifier of a last forwarding device in the preset path, and a device identifier of a specified forwarding device in the preset path; and sending, by the first SDN controller, the specified identifier to a second SDN controller, so that the second SDN controller creates, on the specified forwarding device, a specified port group corresponding to the specified identifier. Therefore, the first SDN controller needs to interact with the second SDN controller only once, to create a port group on the specified forwarding device that is directly controlled by the second SDN controller, and thus the port group creation process is simple.
