Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0037] In the IRF, the active AC is responsible for running, managing, and maintaining the IRF, and the standby AC is responsible for backing up data.

[0038] Such as figure 1The shown IRF network includes AC1, AC2, and switch 3. Among them, AC1 is the active AC, and AC2 is the standby AC. Port aggregation is performed on physical port 4, physical port 5, physical port 6, and physical port 7 to obtain an aggregation group, that is, physical port 4, physical port 5, physical port 6...

Abstract

The embodiment of the present application provides a message forwarding method and device, which are applied to a switch. The method includes: receiving a preset protocol message sent by an AC in the IRF; the preset protocol message includes the active and standby attribute information of the AC; if The active / standby attribute information indicates that the AC is the standby AC. When receiving the first data packet sent by the wired client to the wireless client, select a physical port from the aggregation group on the switch side except the physical port connected to the AC. Port; send the first data message to the AC connected to the selected physical port; if the active and standby attribute information indicates that the AC is the main AC, when receiving the second data message sent by the wired client to the wireless client, the slave Select a physical port from the physical ports connected to the AC in the aggregation group on the switch side; and send the second data packet to the AC. By applying the embodiments of the present application, the impact of data packets on the stacking link can be reduced, and the reliability of the stacking link can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message forwarding method and device. Background technique [0002] IRF (Intelligent Resilient Framework, Intelligent Resilient Framework) connects multiple ACs (Access Controllers, Access Controllers) together through stacking links, and virtualizes them into one device after performing necessary configurations. In IRF, multiple physical ports on a switch are aggregated into an aggregation group, that is, an aggregation group includes multiple physical ports. Wherein, the physical port is a port through which the switch sends data packets to the AC in the IRF. [0003] Based on IRF, the processing of data packets, especially the processing of data packets sent from the wired side to the wireless side is as follows: the wired client sends data packets to the wireless client; Select a physical port among the multiple physical ports in the aggregation group...
