Embodiment 1

[0023] figure 2 It is a flowchart of a method for updating a port index in a multi-device system according to the first embodiment of the present invention. The multi-device system includes a master device and one or more slave devices. Such as figure 2 As shown, in step 200, the main device detects whether the ID of any device in the system has changed; if so, go to step 202 to update the port index of the device whose ID has changed; if not, go back to step 200.

[0024] In the above step 200, the main device detects whether the ID of any device in the system has changed, which means that the main device detects whether the ID of any device has changed in all devices including the main device in the multi-device system. In addition, detecting whether the ID of a device in the multi-device system is changed by the master device may be actively detected periodically or non-periodically. The method for judging whether the ID of a certain device has changed is to compare whether...

Embodiment 2

[0039] Figure 4A It is a schematic diagram of the equipment of the second embodiment of the present invention. The device is used to implement figure 2 The method. A plurality of the devices can form a multi-device system. Such as Figure 4A As shown, the device includes a detection module 400 and a port index update module 402. The detection module 400 is used to detect whether the ID of a device in the multi-device system has changed, and the detection is performed by comparing the ID of each device in the multi-device system before and after the detection. The port index update module 402 is configured to update the port index of the device whose ID has changed according to the changed device ID for the device whose ID has changed in the system, and the port index is used to obtain port configuration data.

[0040] When the detection module 400 detects that the ID of a device in the system has changed, it will notify the port index update module 402 to update the port inde...

Embodiment 3

[0047] The third embodiment of the present invention provides a multi-device system. The multi-device system is composed of multiple devices described in the second embodiment of the present invention. When the device described in the second embodiment of the present invention is a switching device, the multi-device system is a stacking system.

Abstract

The embodiment of the invention relates to a method and a device for updating port index and a multiple device system. The method includes: detecting whether ID (identity) of any device changes in the multiple device system or not by comparing the ID of each device in the multiple device system before the detection with that after the detection; updating the port index of the ID changed devices in the system according to the changed IDs, wherein the port index is used for accessing port configuration data. By the method, the problem that accurate port configuration data cannot be found through the port index due to changing of device ID is solved.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method, equipment and multi-equipment system for updating port indexes. Background technique [0002] The device ID (Identifier, identifier) ​​is used to identify member devices in a multi-device system. One such multi-device system is a stacked system. Stacking refers to combining multiple switching devices with the same hardware structure that support stacking features to logically form a whole switching device. [0003] Each switching device in the stacking system is called a member switching device, which specifically includes a master switching device and one or more slave switching devices. The master switching device is responsible for allocating the IDs of all member switching devices including itself. The configuration file including the ID and all or part of the port configuration data is stored in the main switching device. The main switching device manages the ent...
