Embodiment 1

[0039] This embodiment provides a processing flow after the split of the IRF system, aiming at the topology structure of the IRF system in which the MAD detection link performs MAD detection through an intermediate device. In the following, the embodiment of the present invention will be described in detail by taking the LACP MAD detection manner as an example.

[0040] The topology of the IRF system in this embodiment can be as follows figure 1 As shown, LACP MAD is run between the member devices in the IRF system and the accessed intermediate devices, and the MAD detection is realized by carrying the ActiveID in the extended LACP protocol message.

[0041] Different from the existing technology, when the IRF link fails and the system splits, the downlink port of the device in the Recovery state after the election failure is not in the disconnected state, but keeps Up and sets its state to Block (blocked) , so that it can still exchange MAD detection packets with the device ...

Embodiment 2

[0059] This embodiment provides a processing flow after the split of the IRF system, aiming at the topology structure of the IRF system in which the MAD detection link does not pass through an intermediate device to perform MAD detection. Hereinafter, the embodiment of the present invention will be described in detail by taking the BFD MAD detection manner as an example.

[0060] In this embodiment, the BFD MAD detection function is enabled on all member devices in the IRF system. When the IRF system is normal, only the MAD IP configured on the master takes effect, so the BFD session is in the down state.

[0061] After the IRF link fails and causes the system to split, set the state of the monitoring port (that is, the port connected to the MAD detection link) to Block on the isolation group device, so that the MAD directly connected between the isolation group and the operation group On the detection link, MAD detection packets are still exchanged normally.

[0062] When th...

Abstract

The invention discloses a fault processing method based on an intelligent resilient framework (IRF) system and equipment thereof. The method comprises the steps that: when the equipment in the IRF system detects multi-active conflicts and determines that the equipment self is in a recovery state, a port of a multiple access device (MAD) detection link of the equipment self is kept up, in addition, the port is set into a block state, and the MAD detection messages are exchanged with operation state equipment through the MAD detection link; when the MAD detection messages sent by the operation state equipment are not received in the preset time, protocol messages are sent to the operation state equipment through other ports of the MAD detection link port, and response messages returned by the opposite end are waited; and when the response messages returned by the operation state equipment are not received in the preset time, the uplink service port is closed, and the downlink service port is opened. When the fault processing method and the equipment are adopted, the complete isolation between a user network and an external network caused by the current operation state equipment fault after the IRF cracking occurs can be avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an IRF system-based fault handling method and equipment. Background technique [0002] IRF (Intelligent Resilient Framework) is a software virtualization technology. Through this virtualization technology, the hardware resources and software processing capabilities of multiple devices can be integrated to realize the collaborative work, unified management and uninterrupted operation of multiple devices. maintain. [0003] figure 1 and figure 2 The basic IRF topology structures are respectively shown, wherein, device 1 and device 2 are connected through stack ports to form an IRF link, and at least two devices form an IRF system. Normally, one member device in the IRF system acts as the Master (master device), and other member devices act as slaves (standby devices). Such as figure 1 or figure 2 As shown, in the IRF system, two devices are virtualized into o...
