Embodiment 1

[0030] by figure 2 The matrix stack system shown is an example, in figure 2 The stacking system shown includes the following three stacking groups: stacking group 1 to stacking group 3 . The slots in each stacking group from stacking group 1 to stacking group 3 are connected in a ring, and the first group of internal stacking ports (identified by R-P1) and the second group of internal stacking ports (identified by R-P2) are all set. R-P1 and R-P2 of two adjacent slots in the same stacking group are interconnected through stacking links to form a ring connection between slots in the stacking group. by figure 2 Take stacking group 1 as an example. In stacking group 1, Slot1 is adjacent to Slot2, Slot2 is adjacent to Slot3, and Slot3 is adjacent to Slot1. According to the R-P1 and R- P2 is connected through a stacking link, then R-P2 of Slot1 is connected to R-P1 of Slot2 through a stacking link, R-P2 of Slot2 is connected to R-P1 of Slot3 through a stacking link, and R-P2 ...

Embodiment 2

[0067] by image 3 Stacking system shown as an example, the image 3 The stacking system shown includes the following three stacking groups: stacking group 1 to stacking group 3 . The Slots in each stacking group from stacking group 1 to stacking group 3 are connected in a chain, and all have the first group of internal stacking ports (identified by R-P1) and the second group of internal stacking ports (identified by R-P2), Among them, for the Slots at both ends of each stacking group from stacking group 1 to stacking group 3, only the stacking port in one group is valid, and the stacking port in the other group is invalid, and the valid stacking port identifications of the two ends of the Slot in each stacking group are different. However, both R-P1 and R-P2 of the Slots between the two ends of the stacking group are valid. by image 3 Take stack group 1 as an example. In stack group 1, R-P1 and R-P2 are set for Slot1 to Slot3. The effective stack port of Slot1 is R-P2, an...

Embodiment 3

[0098] by Figure 4 The matrix stack system shown is an example, in Figure 4 The stacking system shown includes the following three stacking groups: stacking group 1 to stacking group 3 . The Slots in each stacking group from stacking group 1 to stacking group 3 are connected in a chain. The Slots at both ends of each stacking group have only one stacking port in the group, and the Slots between the two ends of the Slots in each stacking group are provided with two Intra-group stacking port. by Figure 4 The stacking group 1 shown is taken as an example. In stacking group 1, Slot1 is used as the Slot at one end of stacking group 1, and a stack port in the group (identified by R-P2) is set. Slot3 is used as the Slot at the other end of stacking group 1. Set a The stack port in the group (marked by R-P1), and Slot2 is used as the slot between the two ends of the stacking group 1. Set two stack ports in the group, marked by R-P1 and R-P2 respectively. In stacking group 1, R-...

Abstract

This application provides a topology discovery method and device for a matrix stacking system. The present invention is applied to the network communication technology. In the present invention, the topology information in the stacking group is collected first, and then a stacking group master device is elected from each stacking group to represent the stacking group where it is located to collect topology information of other stacks to realize The topology information in the stacking group and the topology information between the stacking groups are classified to collect topology information, which can quickly and accurately realize the collection of topology information in the matrix stacking system, and realize topology discovery in the matrix stacking topology structure.

Description

technical field [0001] The present application relates to network communication technology, in particular to a topology discovery method and device for a matrix stacking system. Background technique [0002] The essence of stacking is to combine more than one switching device to work together to provide as many ports as possible in a limited space. Multiple switching devices that support stacking are interconnected to form a combined device. The combined device is called a stacking system (Stacking), and each switching device that forms the stacking system is called a member device (Slot). After multiple Slots form a stacking system, it becomes a whole in terms of management and use. [0003] see figure 1 , figure 1 A schematic diagram of the stacking system. exist figure 1 , the stacking system consists of 9 Slots, namely Slot1 to Slot9. Among them, each Slot is configured with two external stacking ports, which are respectively recorded as the first stacking port (P1...
