PROBLEM TO BE SOLVED: To appropriately monitor normality of a frame transmission path in a communication device.SOLUTION: A communication device 100 includes: a test frame generator 20 for generating a test frame having priority information and for changing the priority information on the basis of each test frame; a plurality of flow queues 61 on which each priority of input frames is set; a queue extraction unit for extracting the priority information of the test frame; when a test frame is input, a distribution unit for distributing the test frame to one of the plurality of flow queues 61 according to the priority information extracted by the queue extraction unit; and after inspecting normality of the test frame output from a flow queue 61, a test frame discard unit 23 for discarding the test frame. |
