An apparatus for implementing low power consumption for data switching device includes a dormancy management module that controls an upper layer logic component in a device to enter a low power consumption state when a current state parameter of the device satisfies a preset dormancy configurationcondition; detects whether an energy consumption state of a transmission medium is active; and wakes up the upper layer logic component in the device to enter a normal working state if the energy consumption state of the transmission medium is active. When a preset condition is satisfied, upper layer logic components such as a CPU, a network processor and an optical module in the device, properly stop full-time operation to save energy.
