Description
Technical field
The present invention relates to network communications technology field, particularly a kind of processing method of multi-primary apparatus conflict and device.
Background technology
Intelligent elastic framework (IRF, Intelligent Resilient Framework) system, be by cable multiple devices to be coupled together to form a logical device, wherein each equipment in the IRF system is commonly referred to member device, and the link between each member device is called stacking link.In the IRF system, can elect primary (Active) equipment, miscellaneous equipment is as (Slave) for subsequent use equipment.Because the internal mechanism of IRF system, Active equipment can send the notification packet that carries equipment of itself information (for example Active device id) in the IRF internal system, each member device can be at local record Active facility information, in addition, also can record the IRF system identifier in each member device, the IRF system identifier of each member device record in the same IRF system is identical.
If when occurring stacking link fracture in the IRF system, may cause to occur a plurality of Active equipment in the IRF system.As shown in Figure 1, suppose in this IRF system, to comprise two member devices: member device 1 and member device 2, (state 1) member device 1 is Active equipment before the IRF stacking splitting, member device 2 is Standby equipment.Behind the IRF stacking splitting between member's equipment 1 and the member device 2 (state 2), 2 of member devices can re-elect certainly as Active equipment, because member device also is in the Active state 1 this moment, this may cause network to work.All be in the Active state and produce conflict for fear of member device 1 and member device 2, existing settling mode is generally: allow Master member number minimum IRF and continue normal operation (namely maintaining the Active state), other IRF moves to the Recovery state, and close under the Recovery state all physical ports of other except reserved port among the IRF, to guarantee again forwarding service message of this IRF.
Yet there is following defective in above-mentioned settling mode:
Have more member device if the primary member under 1 conflict situation numbers large IRF, the member device service port in this IRF all can be closed.As shown in Figure 2, an IRF who is formed by three member devices merging may occur and be closed, and another IRF only has a member device to keep the Active state, so will cause the IRF systematic function can not obtain maximum performance.
2, when service port and stacking link port are in the same veneer, if primary member numbers little IRF because this single board default causes stacking splitting, current detection is after the multi-Active conflict, be to allow primary member number little IRF continue normal operation, other IRF can move to the Recovery state.This moment, primary member numbered little IRF because single board default causes service port to work, and other IRF have also closed owing to being in Recovery state service port, at this moment network will occur interrupt.As shown in Figure 3, Port1, Port2, Port3 are in the same veneer, when this single board default, will cause that network interrupts.
If numbering little IRF, 3 primary members before stacking link fracture, are stand-by equipment, this IRF need to be upgraded to host apparatus after division so, because the control plane in the whole IRF system all need to be controlled by primary member, then can cause the little IRF of this numbering to rise the temporary transient interruption that causes network in the process of leading standby.
