Address table maintenance method, device and equipment

Abstract

Embodiments of the present invention provide a method, device, and equipment for maintaining an address table. The method includes: obtaining first index information from a delete operation instruction; deleting a plurality of target MAC address entries corresponding to the first index information from a hardware MAC address table; The target index information linked list corresponding to the index information, and generate the address aging message corresponding to the MAC address entry corresponding to the multiple linked list elements except the linked list head in the target index information linked list, and notify the CPU of the maintenance software MAC address table, In order to make the CPU delete target MAC address entries in batches from the software MAC address table. By simulating and generating multiple address aging messages corresponding to multiple target MAC address entries, the maintenance of the hardware MAC address table and software MAC address table is realized, and the software MAC address can be obtained from the software MAC address table without relying on the structure of the hardware address table and the hardware hash algorithm. Delete target MAC address entries in batches from the table to reduce the difficulty of development and maintenance of network devices.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and equipment for maintaining an address table. Background technique [0002] A Media Access Control (MAC) address is also called a physical address, and is an identifier for identifying a network device node in a local area network. During the physical transmission process of the network, the communication between different network devices can be realized through the MAC address. Taking a switch as an example, each port of the switch has the function of learning and aging dynamic MAC addresses. Each port learns the MAC address carried in the data frame, and stores the MAC address in the hardware MAC address table. [0003] At present, in addition to the hardware MAC address table and the software MAC address table stored in the database, another software MAC address table matching the hardware MAC address table will be established in the network...

AI Technical Summary

Problems solved by technology

For some network devices, it is usually difficult to know the hardware MAC address table structure of the switch chip and the corresponding address access method, or there is a certain difference from the access method in the current address table maintenance scheme. In these cases, it is obviously difficult to create Shadow MAC address table for maintaining MAC address information

In addition, some network devices do not support the block-level query method, so the current address table maintenance scheme cannot be used to maintain MAC address information
