Method and system for ensuring switch to carry out automatic learning on intelligent electronic equipment ports

Abstract

The invention discloses a method and a system for ensuring a switch to carry out automatic learning on intelligent electronic equipment ports. The method comprises the following steps: analyzing an SCD (Science Citation Database) file to generate an application identifier configuration table, wherein lists of application identifiers, names of intelligent electronic equipment and names of the intelligent electronic equipment ports are stored in table items of the application identifier configuration table; analyzing a massage entering each port of the switch in real time to generate an application identifier switching port table, wherein lists of the application identifiers and port numbers of the switch are stored in table items of the application identifier switching port table; and generating an intelligent electronic equipment port table by the application identifier configuration table and the application identifier switching port table, wherein the lists of the application identifiers, the names of the intelligent electronic equipment, the port numbers of the switch and the names of the intelligent electronic equipment ports are stored in table items of the intelligent electronic equipment port table. The invention provides the basis for implementing more application functions of the switch.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and system for automatic learning of ports of intelligent electronic equipment by switches. Background technique [0002] With the increasing scale of power grid and the rapid development of network communication technology, smart substation, as an emerging technical field, is an important driving force for the development of smart grid. Based on Ethernet communication technology, smart substation provides a higher level of information sharing between primary equipment, secondary equipment and secondary equipment, and Ethernet switches are the core equipment for building Ethernet. Each port of an Ethernet switch is directly connected to a device on a network, and generally works in full-duplex mode. The switch can connect many pairs of ports at the same time, so that each pair of network devices that communicate with each other can transmit data without conflict...

Problems solved by technology

[0003] Generally, the switch implements the learning function by parsing the source address and forming a MAC address table. However, this MAC address table can only match the ports of the switch with the MAC addresses of the intelligent electronic devices, and cannot display the relationship between each port of the switch and the intelligent electronic device. The corresponding relationship between the ports of the electronic equipment, and it is also not conducive to the operation personnel to view the message subscription relationship in the network
