Embodiment 1

[0023] figure 2 It is a flowchart of a method for updating a port index in a multi-device system according to Embodiment 1 of the present invention. The multi-device system includes one master device and one or more slave devices. Such as figure 2 As shown, in step 200, the master device detects whether the ID of any device in the system has changed; if yes, enter step 202, and update the port index of the device whose ID has changed;

[0024] In the above step 200, the master device detects whether the ID of any device in the system has changed, which means that the master device detects whether the ID of any device in the multi-device system including the master device has changed. In addition, the master device may detect whether the ID of any device in the multi-device system has changed either periodically or aperiodically. The means for judging whether the ID of a certain device changes is to compare whether the values ​​of the IDs of the devices in the multi-device...

Embodiment 2

[0039] Figure 4A It is a schematic diagram of the device of Embodiment 2 of the present invention. The device is used to implement figure 2 the method. A plurality of said 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 any device in the multi-device system has changed, and the detection is performed by comparing the IDs of each device in the multi-device system before and after the detection. The port index updating 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 ind...

Embodiment 3

[0047] Embodiment 3 of the present invention provides a multi-device system, and the multi-device system is composed of multiple devices described in Embodiment 2 of the present invention. When the device described in Embodiment 2 of the present invention is a switching device, the multi-device system is a stacking system.

Abstract

Embodiments of the present invention relate to a method and a device for updating a port index in a multi-device system, and a multi-device system. The method includes: detecting whether a device ID of a device is changed in a multi-device system, where the detecting is performed by comparing device IDs of each device in the multi-device system before and after the detection; and for a device whose device ID is changed in the system, updating a port index of the device according to the device ID after the change, where the port index is used to acquire configuration data of the port. The embodiments of the present invention solve the problem of failing to find correct port configuration data by using the port index because the device ID is changed.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, device and multi-device system for updating port indexes. Background technique [0002] A device ID (Identifier, identifier) ​​is used to identify member devices in a multi-device system. One such multi-device system is a stacking system. Stacking refers to combining multiple switching devices with the same hardware structure that supports the stacking feature to logically form a whole switching device. [0003] Each switching device in a stack system is called a member switching device, including a master switching device and one or more slave switching devices. The master switching device is responsible for assigning the IDs of all member switching devices including itself. A configuration file including the ID and all or part of the port configuration data is stored in the master switching device. The main switching device manages the entire stack system according to co...
