Stack establishing method and communication equipment

Abstract

The invention discloses a stack establishing method and communication equipment, and belongs to the communication field. The stack establishing method comprises the following steps: first communication equipment sends a stack pairing message to second communication equipment in an existing network through an existing network public channel; the first communication equipment receives the pairing response message sent by the second communication equipment, wherein the repairing response message is used for noticing the first communication equipment that the second communication equipment and the first communication equipment have a same stack serial number; according to the pairing response message, the first communication equipment establishes stacks comprising the first communication equipment and the second communication equipment. According to the stack establishing method disclosed by the invention, by an existing network public channel, the communication equipment is paired and the stacks between the paired communication equipment are established, so that the communication equipment which needs stack establishing is free of interferences of a physical position and a network, and thus, the physical-region-crossing or network-crossing stack between the network equipment is realized.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method for establishing a stack and a communication device. Background technique [0002] With the continuous development of network technology, the requirements for the security of network equipment and the number of ports are also increasing. In the prior art, two or more network devices are connected through stacking technology. On the one hand, it can play a role of spare backup between network devices to ensure data security, and on the other hand, it can play a role in port expansion. . [0003] In the process of implementing the present invention, the inventor found that the prior art has at least the following problems: [0004] In the prior art, one or more direct links need to be established between stacked network devices to transmit stacked protocol messages and data messages. For network devices that cross physical regions or cross networks, during the stac...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, one or more direct links need to be established between stacked network devices to transmit stacked protocol packets and data packets. It is difficult to build a direct link, therefore, it is impossible to achieve cross-physical region or cross-network stacking between network devices
