Abstract
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.
