Abstract:
1. A method for implementing low power consumption for a data switching device, wherein the data switching device comprises a wake-up physical port and a non-wake-up physical port, the method comprises: controlling an upper layer logic component in the data switching device to enter into a low power consumption state, when a current state parameter of the data switching device satisfies a preset dormancy configuration condition, wherein the upper layer logic component comprises at least one of a central processing unit (CPU) and a network processor; detecting whether an energy consumption state of a transmission medium corresponding to the wake-up physical port is active, wherein the detecting comprises: waking up the upper layer logic component in the data switching device to enter into a normal working state if the energy consumption state of the transmission medium corresponding to the wake-up physical port is active; wherein an energy consumption state of a transmission medium corresponding to the non-wake-up physical port is active is not used as a condition for waking up the upper layer logic component.
