Embodiment Construction

[0024] method embodiment

[0025] In this embodiment, a method for detecting a port of a switch chip based on a tagged VLAN is provided.

[0026] The method includes: step S102, connecting the ports of the signaling flow subcard and the media flow subcard of the tested board to the backplane; step S104, connecting each port of the signaling flow subcard and the port of the media flow subcard One carries out self-loop; Step S106, CPU sends data packets through the port between the signaling flow daughter card and the CPU, and the port between the media flow daughter card and the CPU, and receives the data packets at the port sending the data packets; and the steps S108, compare the quantity of the transmitted data packets with the quantity of the received data packets containing the same port label at the ports of the transmitted data packets respectively, and when the two are the same, judge that the port of the tested board is working normally; otherwise judge that the tested...

Abstract

The method includes steps: S102, connecting ports of signaling flow sub card (SFSC) and media flow sub card (MFSC) in board to be tested to backboard; S104, making loop for each port of SFSC and each port of MFSC; S106, through port located between SFSC and CPU and port located between MFSC and CPU, CPU sends out data packets (DP) as well as receives DP from the port, which sends out DP; S108, carrying out comparison between number of DP sent from the port, which sends out DP, and number of received DP of containing same port label; if the sent number is identical to received number, then the method determines that port of board to be determined works normally; otherwise, there is fault in the port of board to be determined. Implementing fault detection for quick switching chip in high efficiency and low cost, the invention can detect fault port in a switching chip precisely. The invention is suitable to fault detection for batch product of a switching chip especially.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a label VLAN-based switch chip port detection method and device. Background technique [0002] Usually, after the single board is processed, some or all of the switching ports of the chip will fail due to the switching chip device or hardware. Therefore, it is necessary to find these defective single boards or sub-cards in the early stage of the single board test, so as to avoid problems difficult to locate caused by the faulty single board in the later stage. [0003] With the rapid development of network communication, Ethernet switching chips integrating multiple contents play an increasingly important role in network communication. How to speed up the development speed of Ethernet switching chips and shorten the verification cycle is the main problem currently facing question. [0004] For the detection of switching chips, although the traditional special-purp...
