摘要： A method and member device for forwarding service messages in an Intelligent Resilient Framework (IRF) system and an IRF system. In the method, each member device in the IRF system is allocated to at least two virtual devices, and at least one stack link for each virtual device is configured in order to connect interface boards among different member devices. When it is determined according to a forwarding entry of an interface board in a first member device receiving a service message that the service message is to be transmitted to a second member device, the service message is forwarded via the at least one stack link configured for the virtual device of that interface board.

摘要： A method for controlling flow and a chassis switch in a stack system are provided. The stack system includes multiple chassis, each of the multiple chassis includes a main control board and an interface board, traffic flow and control flow in each of the multiple chassis are independent of each other when each of the multiple chassis operates normally. In the method, when a main control board in a chassis in the stack system is unavailable, control flow to be transferred to a destination interface board is switched to a traffic flow channel corresponding to the destination interface board from a control flow channel, and the control flow is transmitted to the destination interface board through the traffic flow channel.

摘要： The invention provides a stacking system and a method for traffic switching in the stacking system, comprising: when newly joined devices in the stacking system make the daisy chain topology change to ring topology, block a stack port of one of the newly joined devices; after the devices in the stacking system perform another topology convergence process, the master restores the configuration of the newly joined devices; after the configuration of the newly joined device one of whose stack ports is blocked is restored, it sets its blocked stack port to the forwarding state, calculates the shortest path based on the ring topology, and sends first notification packets for topology change from daisy chain type to ring type through its two stack ports; each device that receives the first notification packets re-calculates its shortest forwarding path respectively and switches the traffic, and then forwards the first notification packets. This invention can prevent traffic interruption that occurs when the topology of a stacking system changes from daisy chain to ring.
