Method, device and system for configuring pre-emphasis for interconnection equipment and network device

Abstract

The invention discloses a method, a device and a system for configuring pre-emphasis for interconnection equipment and a network device so as to be used for improving the universality of the pre-emphasis configuring method. The method for configuring the pre-emphasis for the interconnection equipment comprises the steps that a local terminal port and an opposite terminal port negotiate to establish a virtual switch unit (VSU) after connection between the local terminal port and the opposite terminal port is detected to be established, and the local terminal port is configured to be a port of a virtual switch link (VSL); a local terminal sequentially selects a group of pre-emphasis parameters from a pre-emphasis configuration table to configure a chip connected with the local terminal port, and continuously sends test messages to the opposite terminal within a preset length of time by using each group of the configured pre-emphasis parameters; and the chip is configured according to the effective pre-emphasis parameters selected by the opposite terminal port, and the effective pre-emphasis parameters are selected by the opposite terminal port according to a test result of the received test messages.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method, device, system and network equipment for pre-emphasis configuration of interconnected equipment. Background technique [0002] An interconnection port refers to the situation where two ports on two network devices are connected through a physical transmission medium (such as a copper cable module or an optical module), such as figure 1 As shown, port A on device 1 and port B on device 2 are connected through a physical transmission medium, and packets sent from port A directly reach port B through the physical transmission medium, and vice versa. Two network devices connected through interconnection ports can be called interconnection devices. [0003] Existing access and aggregation switch devices have optical ports. In order to realize short-distance interconnection of switch devices and save costs, copper cable modules are usually selected for ...

Problems solved by technology

Its advantage is that it can quantify the signal quality of the sending end, which is more intuitive. The disadvantage is that it is impossible to test each model of product. For products of the same design, due to PCB (Printed Circuit Board, printed circuit board) differences, chip differences or case (shielding cover) , the container used to insert optical modules or copper cable modules) differences will lead to indivi
