Report negotiation method, device and system

Abstract

The embodiment of the invention discloses a method, a device and a system used in message negotiation, wherein after a port in passive OAM mode receives an 802.3ah Hello message sent by an active port, bit-by-bit analysis of the OAM configuration field in the message is completed; if the passive port supports the corresponding function of a bit but the active port does not support, the function is shielded. The embodiment of the invention ensures that the passive mode port can furthest ensure that the OAM configuration mode of the passive mode port keeps synchronization with an active mode port; moreover, both ports do not need to be set at the same configuration, thereby simplifying port configuration.

Description

Technical field [0001] The present invention relates to the technical field of network communication, in particular to a message negotiation method, equipment and system. Background technique [0002] Ethernet technology is simple and easy to use, low in price, and bandwidth can be continuously improved. Whether as a business or as a network structure, it has been widely used in enterprise networks, metropolitan area networks, and wide area networks. However, the maintainability and operational capabilities of traditional Ethernet are relatively weak. With the gradual expansion of the scope of Ethernet promotion, the demand for Ethernet OAM (Operation Administration and Maintenance, operation, management and maintenance) functions is becoming stronger. [0003] IEEE 802.3ah is a protocol for point-to-point fault detection based on Ethernet (hereinafter referred to as "802.3ah"). 802.3ah detection has two working modes: active and passive. The device in the active mode will initia...

Problems solved by technology

[0004] Devices from different manufacturers have different capabilities to support various functions stipulated in the 802.3ah protocol, mainly reflected in whether they support the functions of variable request and response, link event, one-way, and loop, and the current protocol does not stipulate that different manufacturers 1. Different devices must support the above functions exactly the same during the 802.3ah interworking process. If the functions supported by the two devices are different during the negotiation process, the two parties will not be able to negotiate successfully.

[0005] As shown in Figure 1, assume that device A supports variable requests and responses, while device B does not support variable requests and responses. During the negotiation process, if the support for functions must be completely consistent, the two parties will not be able to negotiate successfully.
