Problems solved by technology

[0005] 1. BFD packets are sent before the stack system splits. Since the VSL link does not split most of the time, uninterrupted detection will undoubtedly cause a huge waste of bandwidth resources and CPU resources. When the detection time is at the millisecond level and especially when stacking more devices
[0006] 2. Extending the BFD message for active role election increases the complexity of protocol processing and poor compatibility with other manufacturers.

Embodiment 1

[0058] Embodiment 1. A stacking system composed of two member devices performs stack split detection;

Embodiment 2

[0059] Embodiment 2: A stacking system composed of multiple member devices performs stack split detection.

[0060] In the first embodiment, if image 3 As shown in the figure, in a stack system composed of two member devices, member device A has higher activity priority due to its better performance and richer functions, and device B has lower performance and lower activity priority, and the detection method uses the standard The BFD detection protocol is used for detection. The MAC address of device A is MAC_A, and the MAC address of device B is MAC_B. To further illustrate the steps, combine image 3 For the stacking system shown, the quick detection process for stack splitting is as follows: Figure 4 shown, including the following steps:

[0061] Step 401: The interface module of member device A and the interface module of member device B respectively create VLAN interfaces for the member devices they belong to, and set the created VLAN interfaces to be closed. For e...

Embodiment 2

[0069] In embodiment 2, such as Figure 5 In the stack system shown, there are four member devices, device A, device B, device C, and device D. The activity priorities of the four member devices are device B, device A, device C, and device D in descending order. Among them, device B has the best performance, so the activity priority is set to the highest, and the IP address of the VLAN detection interface is set to the lowest. combine Figure 5 For the stacking system shown, the quick detection process for stack splitting is as follows: Figure 6 shown, including the following steps

[0070] Step 601: The interface modules of device A, device B, device C, and device D create VLAN interfaces for the devices respectively, and set them to be closed. These four VLAN interfaces have the same VLAN ID and are named VLAN1, VLAN2, VLAN3, and VLAN4 in turn.

[0071] Step 602: The interface modules of the four member devices bind IP addresses to the created closed VLAN interfaces acc...

Abstract

The invention discloses a stacking and splitting quick detection method, which comprises the following steps: A, each set of member equipment of a stacking system establishes a virtual local area network (VLAN) interface, configures address information on the VLAN interface and sets the VLAN interface to a closed state; B, the member equipment generates an address resolving table comprising the address information of other sets of member equipment according to an established stacking detection link; C, when a certain set of member equipment detects that a virtual exchange link has a fault, the member equipment starts the closed VLAN interface, establishes a bidirectional forwarding detection (BFD) session on the started VLAN interface, encapsulates a BFD detection message according to the address information in the address resolving table and interacts with the member equipment at the opposite end; and D, the member equipment of which the local BFD session reaches a hand-shaking finish UP sate compares a selection rule according to set main equipment, and when the member equipment is determined to be slave equipment by comparing source address information in the received BFD detection message with target address information, the member equipment closes all service interfaces. The invention also discloses a stacking and splitting quick detection device.

Description

technical field [0001] The present application relates to the field of data communication, in particular to stacking technology, and in particular to a method and device for quickly detecting stack splits. Background technique [0002] Stacking technology is to connect multiple network devices (the network devices are usually switches) together to form a stacking system through stacking cables, so as to provide as many ports as possible in a limited space; these network devices in the stacking system are collectively called stacking Member devices of the system. With the continuous improvement of network stability and equipment reliability requirements, the applicant proposed a virtual switching technology (VST, Virtual Switching Technology) for high-end network equipment on the basis of traditional stacking technology. Virtual switching technology is a technology based on a stacking system that virtualizes multiple physical devices into a single virtual device. The stackin...
