Embodiment Construction

[0039] In the method for updating the MAC address table provided by the embodiment of the present invention, when a new MAC address table entry is learned, it is determined whether the address table entry needs to be transferred to the external memory according to the number of address table entries in the internal address table. Avoid frequent transfer of address table entries between internal address table and external memory. The flow process of the inventive method is as Figure 5 As shown, the execution steps are as follows:

[0040] Step S11: A new address entry is learned.

[0041]When a network device in the network, such as a switch, receives a message, it obtains the source MAC address, VLAN number and corresponding port number in the message, and realizes that the internal address table learns a new MAC address entry. Generally, learning of MAC address entries in network devices is implemented by hardware. The learned new address entry generally refers to an addr...

Abstract

The invention discloses an updating method, device and network equipment of a media access control address table. The updating method comprises the following steps: when learning new address table entries, judging whether the number of the address table entries in an internal address table is more than the set upper waterline; when the number of the address table entries in the internal address table is larger than the set upper waterline, transferring at least one address table entry except the new address table entries from the internal address table to an external storage until the number of the address table entries in the internal address table is less than the set lower waterline; and when the number of the address table entries in the internal address table is not more than the set upper waterline, avoiding the address table entries in the internal address table from being transferred to the external storage. By utilizing the method, the frequent transferring of the address table entries between the internal address table and the external storage is avoided, the memory occupancy rate is reduced, and the system performance of the network equipment is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and network equipment for updating a Media Access Control (MAC) address table. Background technique [0002] Each node in the Ethernet corresponds to a MAC address. When the switch receives an Ethernet message, it extracts the source MAC address in the message, and stores it in the hardware together with the port number connected to it and the Virtual Local Area Network (VLAN) number. Among the entries, this hardware entry is called a MAC address table. When the message needs to be forwarded to the node, according to the destination MAC address of the message, the port number connected to it is searched in the MAC address table, and the message is forwarded from the port. [0003] figure 1 The figure below is a schematic diagram of the working principle of the MAC address table in the switch. Among them, the MAC addresses of node 1, node 2, and ...
