Description

 Automatic configuration method and device for static medium access control address table

 The present invention relates to the field of network communication technologies, and in particular, to a method and an apparatus for automatically configuring a static medium access control address table. Background technique

 In the process of Layer 2 switching, the NE needs to use the Medium Access Control (MAC) address table. The fields of the address table include the outgoing port, the destination MAC address, and so on. For the virtual local area network (VLAN, Virtual Layer 2 switching of the Local Area Network). The VLAN ID field is also required in the MAC address table.

 When a network element receives a data packet from a port, it first reads the source MAC address in the packet header of the data packet, so that the source MAC address of the device is connected to the port, and then reads the destination MAC address in the packet header, and The corresponding record is found in the MAC address table according to the MAC address, so that the data packet is copied to the destination port indicated by the record, and the layer 2 exchange is completed.

 In the prior art, there are two ways to form a MAC address table: a self-learning mode and a static configuration mode. The self-learning mode is implemented by the network element by using a flooding mechanism. Specifically, if the MAC address cannot be obtained in the foregoing process. If the record is found in the table, the network element broadcasts the data packet to all the ports. When the destination network element responds to the network element, it can learn the port corresponding to the destination MAC address and record the MAC address to the MAC address. In the address table, a MAC address entry is formed. In the static configuration mode, the user enters and configures the MAC address entry by using the network management system, and sends the MAC address entry to the network element by means of a command. The NEs are saved in the MAC address table. These entries are called static MAC address entries.

The static configuration mode does not form a broadcast storm. The static configuration mode is mainly used to prohibit forwarding of unnecessary data packets, rapidly forming a MAC address table, and MAC address table. There are other scenarios with special requirements, as well as scenarios where non-destructive business switching needs to be completed.

 In the existing technology of configuring a static MAC address table of a network element, the user needs to know in advance: the port with the physical link in the network element, the port of the peer network element of each physical link, and the VLAN interface included in the port. And the peer network element MAC address. According to other constraints, the user determines the static MAC address entry set of the network element according to the mechanism of the Layer 2 switching, and then inputs the entries to the network element through the network management system, and the network element stores the MAC address into the MAC address. In the table. This process needs to be done manually, so the workload is large, and the configuration is inefficient and error-prone. Summary of the invention
