The invention discloses a configuration circuit of a switching chip and a parameter configuration method of the switching chip. The circuit comprises the switching chip and a logic chip, and the switching chip comprises at least one interface; the logic chip comprises a configuration module, the configuration module is used for carrying out parameter configuration on at least one interface, the logic chip is connected with the switching chip through a first channel, a second channel and a third channel, and the configuration module is connected with the switching chip through the third channel; after receiving the mode configuration signal sent by the first channel, the switching chip determines to use a first mode to carry out parameter configuration on each interface in the at least oneinterface, and the first mode is a mode for carrying out parameter configuration by using a configuration module; after the switching chip receives the reset signal sent by the second channel, the parameter of each interface is set as an initial value; and after receiving the configuration parameter signal sent by the third channel, the switch chip sets the parameter of each interface as a parameter value corresponding to the configuration information.
