Problems solved by technology

[0006] Although the existing technology can realize the reading of MAC address table entries, there are also the following problems: due to the chip hardware design, the switching chips provided by different manufacturers have very different processing methods for reading the address table, and there is no uniform rule
MAC address entries cannot be displayed in the dictionary order of the VLAN+MAC format generally expected by the network management system
In addition, routing devices and other devices have many slots, and there may be switching chips from various chip manufacturers in the slots, which may cause inconsistencies in the efficiency of reading table items. The method of entry is very inefficient and consumes a lot of processor resources, so frequent reading of a large number of address table entries will greatly affect the performance of the device

Embodiment Construction

[0058] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0059] In the present invention, the flow of a method for managing MAC address entries is as follows figure 2 shown, including the following steps:

[0060] Step s201, creating a data structure for storing managed MAC address entries.

[0061] The type of this data structure can be selected according to needs, such as adopting a data structure based on AVL (Adelson-Velsky Landis) balanced binary tree, which is used to store MAC address entries existing on all switching chips in the routing device, different The MAC address entries in this data structure are arranged in lexicographical order.

[0062] Step s202, acquiring the MAC address entry stored in the switch chip.

[0063] Step s203 , updating the local MAC address entry according to the acquired MAC address entry of the switching chip.

[0064] Through this step, th...

Abstract

The present invention discloses a management method of a MAC address table item, which comprises the following steps that the MAC address table item stored by the switch chip is got, the discrepancy table item of the MAC address table item and the MAC address table item get last time is got; a local maintenance MAC address table item is updated according to the discrepancy table item. The presentinvention also discloses a MAC address table item management device. Through using the present invention, the MAC address table item based on the lexicographic order is automatically generated and maintained on the routing device, the discrepancy of the MAC address table item on the switch chip of different manufacturer is overcome, and a good open framework is provided for the routing device maintenance and expansion.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for managing MAC (Media Access Control, Media Access Control) address entries. Background technique [0002] With the development of data communication technology, the networking requirements for routing and switching integration on routing devices are becoming more and more obvious. This type of networking can simplify the network layer and reduce networking complexity and maintenance costs. [0003] The technical solution often used at present is to fix the switch port or integrate the switch module on the routing device. As the device network becomes more and more complex, the maintenance personnel propose to query and display the Ethernet address of a certain switch port or switch module of the routing device in lexicographical order. Network conditions, troubleshooting and resolution of related issues. [0004] In the MAC address entry...
