Detection processing method and device for host computer confliction and network device

Abstract

The invention provides a detection processing method and device for host computer confliction, and a network device. The detection processing method for the host computer confliction comprises the following steps of: automatically correcting a local end IP (Internet Protocol) address in a BFD (Bidirectional Forwarding Detection) pair according to the quantity of devices in a current stacked topology; constructing a BFD session according to the quantity of devices in an original stacked topology, the quantity of the devices in the current stacked topology and an opposite end IP address before correction and the local end IP address after correction in the BFD pair; and reserving an optimal stacked topology according to the successfully constructed BFD session. The detection processing device comprises a correction module, a construction module and a decision module. The network device comprises a detection processing device for the host computer confliction. The embodiment of the invention quickly and effectively solves a problem of the confliction between double host computers and ensures the maximization of a network service.

Description

technical field [0001] The present invention relates to communication technology, in particular to a host conflict detection and processing method, device and network equipment. Background technique [0002] Stacking refers to combining more than one device to work together to form a "combined device" to provide as many ports as possible in a limited space. Users can manage the "combined device" to realize the Management of all devices in the stack. In a switch stacking system, all single devices are called member devices, and member devices are divided into master (Master) devices and slave (Slave) devices according to different functions. Among them, the master device is elected by roles and is responsible for managing the entire stack system. Only one member device in a stack system can be the master device at a time. The slave device belongs to the master device and operates as its backup device. In the stack system, all slave devices except the master device are slave...

AI Technical Summary

Problems solved by technology

When a stack split occurs in the topology, two devices with identical configurations will appear on the network, which will cause the network to fail to work normally and cause dual-host conflicts

[0003] In the prior art, bidirectional forwarding detection (Bidirectional Forwarding Detection; hereinafter referred to as: BFD) detection method is usually used to detect dual-host conflicts in the stack system, and a BFD link is added to the stack topology. Priority to choose to reserve or shut down the stack system; and if the stack system of the member device with the highest priority is not the optimal stack system, the problem of dual-host conflicts cannot be effectively resolved, and the maximum network service cannot be guaranteed
