Abstract

The embodiment of the invention discloses an ether port auto-negotiation and network communication equipment. According to a port mode list arranged in advance, from a first port mode, an ether port chip A of a first communication equipment begins to establish a link by the auto-negotiation method of the present port mode and an ether port chip B; if the establishment is failure, the link is switched to a next port mode in the port mode list, until the link is successfully established by the auto-negotiation method of the present port mode and the ether port chip B, and the present port mode is determined as the port mode of the ether port chip B. Consequently, the physical port of the ether port chip A is controlled by switching different port modes for carrying out auto-negotiation with the opposite terminal port, and the invention can fully perform the chip characteristics for supporting multiport modes, enhance interconnection between internal modes of the equipment and boards, improve flexibility of interconnection between equipments, and avoid complexity and cost of software forced arrangement, and avoid trouble of manually operation, and simplify the arrangement of equipment.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a method for self-negotiation of an Ethernet port and a communication device. Background technique [0002] In existing communication devices (such as switches, routers, blade servers, gateways, etc.), there are many types of ports used for inter-board interconnection and inter-module interconnection. In terms of the most commonly used Ethernet ports, there are also different media and different speeds. port mode, such as 1000BASE-X, 1000BASE-T, 100BASE-FX, 10GBASE-SR, etc., the Ethernet port of some chips can support multiple port modes. [0003] In the IEEE specification, some port modes define the auto-negotiation mode, such as 1000BASE-X, 10 / 100 / 1000 / 10GBASE-T, etc. Through the auto-negotiation mode defined in the IEEE specification, the communication device can use the self-negotiation mode supported by its own chip The port mode information is communicated to the o...
