Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] Such as figure 2 As shown, the embodiment of the present invention provides a method for sending messages in a dual-machine ring stacking system, including:

[0025] Step 101: When a dual-machine ring stacking system is established or the current stacking system is changed from a non-dual-machine ring stacking system to a dual-machine ring stacking system, bind the two stacking ports included in the stacking device into one logical port, so that The dual-machine ring stacking system cannot form a loop;

[0026] Step 102: When the stacking device needs to send a message, it sends the message to a neighbor stacking device of the stacking device through a logical port of the stacking device, and the message is other messages exce...

Abstract

The invention discloses method and device for sending message in a dual-machine annular stacking system, belonging to the field of communication. When dual-machine annular stacking system is built, or the condition that a non-dual-machine annular stacking system is changed into the dual-machine annular stacking system in the current stacking system is monitored, a stacking device binds two self-comprising stacking ports into a logical port so as to make the dual-machine annular stacking system not form a loop circuit on the logical level; when the message needs to be sent, the stacking device sends the message to an adjacent stacking device through the logical port, and the message is other message except information message. The device comprises a binding module and a transmitter. For the invention, entire bandwidth can be used in the dual-machine annular stacking system.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for sending messages in a double-device ring stacking system. Background technique [0002] A stacking system refers to the combination of multiple stacking devices to logically form a whole switching device. The network topology of the stacking system includes chain connection and ring connection. Ring stacking system: The dual-machine ring stacking system can form a ring at the logical level to generate a broadcast storm. In order to avoid the broadcast storm in the dual-machine ring stacking system, it is necessary to break the ring formed in the dual-machine ring stacking system. [0003] For example, see figure 1 , stacking device SW_1 includes stacking ports A and B, stacking device SW_2 includes stacking ports 0 and 1, stacking port A of stacking device SW_1 is connected to stacking port 1 of stacking device SW_2 through stacking link C, and the stacking o...
