Abstract

The embodiment of the invention relates to a network port loop detection method and system. The method comprises the following steps: receiving and responding to a first data reading instruction, and reading at least one first module controller identification group from a first system controller; receiving and responding to a second data reading instruction, and reading at least one second module controller identification group from a second system controller; processing each first module controller identification group and each second module controller identification group; in response to the fact that the first processed first module controller identification group is the same as the first processed second module controller identification group, determining that a loop exists in a first on-load interface of the first Ethernet switching equipment and a second on-load interface of the second Ethernet switching equipment; and displaying the loop relationship between the first on-load interface and the second on-load interface. According to the embodiment of the invention, the network port loop relationship between the Ethernet switching devices can be automatically detected.

Description

technical field [0001] The invention relates to the technical field of display control, in particular to a network port loop detection method and a network port loop detection system. Background technique [0002] At present, LED display screens are widely used in various occasions in our daily life due to their high visibility and low power consumption. The application of the LED display is inseparable from the LED display control system. The LED display control system typically includes a system controller (such as a sending card) and a plurality of module controllers electrically connected to the system controller (such as a receiving card, scanning card), and each module controller is used to carry one or more LED light board modules in the LED display body. [0003] In practical applications, in order to realize the display of large-scale LED display screens, multiple system controllers are required. At the same time, in order to ensure the stability of the LED display...
