Abstract

The embodiment of the application provides a port switching method, a main control board card, a service board card and a switching device and relates to the technical field of communications. The method comprises the following steps: the main control board card of the switching device determines at least one standby port on the switching device, wherein the at least one standby port is differentfrom a main port currently used on the service board card of the switching device; the main control board card sends standby port information of the at least one standby port to the service board card; and when determining the main port is in an unavailable state, the service board card switches the currently used main port to a target standby port in the at least one standby port according to thestandby port information. When determining that the current main port is in the unavailable state, the service board card can directly and quickly switch the currently used main port to the target standby port to work based on the standby port information, thereby avoiding the technical problem of port switch behind time as switch of the main control board card takes too long.

Description

technical field [0001] The present application relates to the technical field of communication, and specifically relates to a port switching method, a main control board, a service board and switching equipment. Background technique [0002] The spanning tree protocol is a layer-2 ring-breaking protocol commonly used in Ethernet networks, and is used to reduce the forwarding path in a broadcast domain to a tree structure. [0003] At present, when the switching device communicates with other devices based on the spanning tree protocol, the main control board of the switching device can control the corresponding port in the service board on the switching device to process the message based on the spanning tree protocol. However, when the network status changes and the corresponding port in the service board needs to be changed, the main control board can determine a new port for the service board to process the message based on the received protocol message processing, but su...
