Embodiment 1

[0061] See image 3 , Is a flowchart of an embodiment of a method for detecting interface connections between devices of the present invention. The method specifically includes:

[0062] This embodiment is described based on an Ethernet interface, and the interface working parameters supported by the Ethernet include at least one of a rate, a duplex state, and a flow control parameter. Among them, the rate includes 10M, 100M, 1000M, and 10G; the duplex state includes half-duplex state and full-duplex state, and the flow control parameters include full-duplex flow control and no flow control. For example, the interface working parameters supported by Ethernet include but are not limited to: 10M, half-duplex working mode; 100M, full-duplex working mode; 1000M, half-duplex working mode; 100M, full-duplex flow Control working mode, etc.

[0063] The device in this embodiment includes a first device and a second device that communicate with each other. The first device and the second ...

Embodiment 2

[0077] In this embodiment, the interfaces on the first device and the second device are divided into multiple groups according to their functions. For example, the 8 network ports in the first device are divided into two groups, and the 4 network ports in each group can be mixed at will, but No intermixing between the two groups. The 8 network ports in the second device are also divided into two groups, each group of 4 network ports can be mixed at will, but the two groups cannot be mixed. In this case, the recommended working parameters of the four network ports in the same group can be set to the same speed and duplex state, but different groups have different working parameters. As long as the network cable connects the two interfaces of different groups on the first device and the second device, it can be detected and alarmed.

Embodiment 3

[0079] This embodiment is described based on PCIe (PCI Express), QPI (QuickPath Interconnect) interface or RapidIO interface. The PCIe is a high-performance communication link interface for personal computers and servers. It can not only realize the interconnection between two devices on a single board, but also interconnect the two devices through cables. For example, servers and flash storage arrays both provide PCIe interfaces to the outside, and they can be interconnected through PCIe cables.

[0080] The working modes supported by the PCIe protocol include, but are not limited to, bit width parameters and / or rates, where the bit width can be 1x, 2x, 4x, 8x, 12x, 16x or 32x, and the rate supports 2.5G, 5G and 8G, and multiple Kind of combination.

[0081] In this embodiment, the first working parameter is set in the link control2 register of the first interface, and the second working parameter is set in the link control2 register of the second interface; respectively, in the l...

Abstract

The invention discloses a method and a device used for detecting inter-equipment interface connection. The method comprises the following steps of setting the recommended working parameter of a first interface as a first working parameter; obtaining the second working parameter of a second interface by auto-negotiation operation; judging whether the second working parameter is equal to the first working parameter or not; if not, warning to indicate that connection is not matched; if so, setting the recommended working parameter of the first interface as a third working parameter; sending the third working parameter to the second interface by the auto-negotiation operation; receiving the third working parameter sent by second equipment via the second interface; and enabling the first interface and the second interface to communicate via the third working parameter. According to the invention, whether the second working parameter obtained by the first interface is equal to the set first working parameter or not is judged to judge the matching relationship of the interfaces, the problem that the interfaces are likely to be subjected to mixed insertion in the prior art is solved, the manual operation miss probability is reduced, and the maintainability and the reliability of the communication equipment are improved.

Description

Technical field [0001] The present invention relates to the field of computer and communication technology, and in particular to a method and device for detecting interface connections between equipment. Background technique [0002] Communication devices often need to be interconnected to exchange information, such as figure 1 As shown, it is a typical interconnection scenario between communication equipment frames, which includes a center frame and three service frames (service frame 1, service frame 2, and service frame 3). Each frame has a switch board. The switch board of the frame is connected to the switch board of the center frame through an Ethernet interface to achieve business convergence. [0003] It is often necessary to follow certain rules in the distribution of interconnection interfaces of communication devices. For example, a device must be connected to the designated interface of another device, and cannot be connected to any one of multiple interfaces at will, o...
