Ring network configuration detection method and device

Abstract

The invention provides a ring network configuration detection method and device. The method comprises the following steps that an adjacent node receives an ERPS protocol message sent by a first node, wherein if the first node is a master node, the ERPS protocol message carries master port identification and direct connection receiving identification, and if the first node is not the master node, the ERPS protocol message carries common port or adjacent port identification and forwarding receiving identification; the adjacent node judges whether port role identification carried by the ERPS protocol message is not the master port identification and receiving mode identification carried by the ERPS protocol message is the direct connection receiving identification; if yes, the adjacent node determines that configuration of the port role identification of the adjacent port is wrong. The ring network configuration detection method and device solves the technical problem that a ring network manager cannot know whether configuration of nodes in a ring network is right or not in the prior art, ring network communication failure caused by wrong configuration of the nodes in the ring network is avoided, and the communication quality of the ring network is guaranteed.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of Ethernet, and in particular to a ring network configuration detection method and device. Background technique [0002] With the widespread application of Ethernet in LANs, the scale of Layer 2 networks is getting larger and larger, and the commonly used spanning tree technology is insufficient in terms of expansion and convergence speed. Extreme company proposed the ERPS protocol ring network protection technology in 2003, achieving 50ms switching performance. The basic idea of ​​Ethernet ring network protection: by simplifying the network, decomposing the network into the most basic unit of the ring, simplifying the calculation, and finally achieving the purpose of fast convergence. The emergence of ERPS technology has solved the problem of spanning tree very well. ERPS Ethernet ring network protection protocol is a special link layer protocol, which is specially used to constr...
