A method and device for automatic testing of debug ports

Abstract

The present invention discloses an automatic testing method for a debug port. The method comprises: a transceiver loopback module is inserted into a debug port of a main control card; the main control card sends a port switching command to at least one in-position service card according to a certain frequency; and the service card that receives the port switching command switches a serial port of the current card onto the debug port, and sends out testing data from the serial port according to a fixed data transmission frequency, and sets a time threshold of receiving testing data, and compares received testing data with the sent testing data if the testing data is received within the set time threshold of receiving the testing data, and records a testing result of the current card to be passed if the received testing data is consistent with the sent testing data. The present invention further provides an automatic testing apparatus for a debug port. The apparatus provided by the present invention adds the transceiver loopback module and performs an effective automated test on a whole hardware line connected to the debug port on the service card by time difference mating, and the testing result appears clear. During a batch inspection, the inspection efficiency is improved.

Description

technical field [0001] The invention belongs to the field of data communication, and in particular relates to a method and a device for automatic testing of a debug port. Background technique [0002] With the high-end development of communication equipment, the application of rack-mounted architecture on communication equipment is becoming more and more common. In order to view information conveniently, rack-mounted communication equipment will design a debug port on the main control card. It can be switched to the serial port of any business card, which is convenient for monitoring or viewing the business card after the equipment fails. Such as figure 1 As shown in the figure, the Debug port is located on the main control card of the whole machine, and is connected to the CPU serial port of other service cards through a bus on the backboard, so as to realize the same function as the local serial port of the service card. [0003] As the production quantity of communicati...

Problems solved by technology

[0004] The main purpose of the present invention is to provide a method and device for automatic testing of debug ports, so as to solve the problem that the CPU system on the service card cannot perceive whether the card is connected to the existing communication equipment when the debug port of the existing communication equipment is automatically tested for hardware quality. On the debug port, the information of the main control card and the service card cannot be synchronized
