Automatic switch configuration method for hierarchical topology and medium

Abstract

The invention discloses an automatic switch configuration method for hierarchical topology and a medium. The method comprises the following steps: setting all ports started by a switch to be in a BLOCK state; for each switch, dividing all switches connected with an upper-layer switch into different VLANs, acquiring an IP network segment of each VLAN from an upper-layer main switch, and setting the IP network segment as a high priority; selecting a switch with the highest priority and the smallest MAC address from each small system as a main switch; in addition, dividing other ports in the small system into the VLAN1, and enabling the equipment connected with the VLAN1 to acquire the IP network segment from the main switch; acquiring, by the main switch, the IP network segment of the VLAN1 from the upper-layer main switch, and configuring the IP network segment for other switches and terminal equipment; and if the switch loses the connection with the main switch, returning to the initial starting state for reconfiguration. According to the invention, automatic network configuration can be realized, network redundancy processing is carried out through real-time network monitoring and intervention, and extra cost does not need to be increased.

Description

technical field [0001] The invention belongs to the technical field of switch configuration in data communication, and in particular relates to a switch automatic configuration method and medium for hierarchical topology. Background technique [0002] In important communication and control equipment, the flexibility of the communication system is crucial to the flexibility, stability and business of the entire system. Due to changes in the environment, the switch configuration usually needs to be changed to ensure normal communication between devices. This often requires professional knowledge and rich experience. Some human errors may cause the entire network to be unavailable, seriously affecting system stability and service availability. In order to ensure the flexibility of these switches, it is usually handled with a large layer 2 network or pre-configured. [0003] in: [0004] Large Layer 2 network: It means that all devices are in a subnet for communication. This...
