A method and device for handling multi-master device conflicts

Abstract

The invention provides a method and a device for processing conflicts of a plurality of main equipment. After an IRF (Impulse Response Function) system is cracked and a plurality of Active member equipment is detected, the quantity of network member equipment of the IRF system of each Active member equipment is calculated to keep the IRF system with the more quantity of the network member equipment at an Active state; other IRF systems are transferred to a Recovery state; single-board fault information of the IRF system is collected and the IRF system with a single-board fault is transferred to the Recovery state; previous main equipment is searched in a plurality of the Active member equipment; the IRF system of the previous main equipment is kept at the Active state; and the other IRF systems are transferred to the Recovery state. According to the method and the device disclosed by the invention, when the IRF system is cracked and the conflicts of a plurality of the main equipment exist, the influences to a network are reduced to the minimum.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method and device for processing multi-master device conflicts. Background technique [0002] Intelligent Resilient Framework (IRF, Intelligent Resilient Framework) system is to connect multiple devices through cables to form a logical device. Each device in the IRF system is usually called a member device, and the link between each member device is called a stacking chain. road. In the IRF system, an active (Active) device will be elected, and other devices will be used as backup (Slave) devices. Due to the internal mechanism of the IRF system, the Active device will send a notification message carrying its own device information (such as the Active device ID) inside the IRF system, and each member device will record the Active device information locally. Record the IRF system ID. The IRF system ID recorded by each member device in the same IRF system i...

Problems solved by technology

At this time, the service port of the IRF with a small active member number cannot work normally due to a board failure, and the service ports of other IRFs are also closed because they are in the Recovery state. At this time, a network interruption occurs.

like image 3 As shown, Port1, Port2, and Port3 are all on the same board. When this board fails, the network will be interrupted.

[0007] 3. If the IRF with the smaller active member number is the standby device before the stack link breaks, the IRF needs to be upgraded to the active device after the split. Since the control plane in the entire IRF system needs to be controlled by the active member, It will cause the IRF with a small number to temporarily interrupt the network during the process of upgrading to the master
