Problems solved by technology

[0004] In a switch that does not implement hot backup of the control plane protocol, the master / standby switchover process will cause the link of the control plane protocol to be disconnected, and the process of sending BPDU packets from the master to the line card will be interrupted. When the port of the non-root switch does not receive the When sending BPDU messages, it will consider that the network structure has changed, and recalculate the spanning tree, which will cause network vibration and abnormal data forwarding

Abstract

A switching control method and device, a switch, and a computer-readable storage medium, the switching control method comprising: the line card does not receive a bridge protocol data unit message from the main control within a first preset time and is currently in the active / standby mode During the switching process, the line card forwards the locally buffered bridge protocol data unit message to the non-root switch every second preset time. In the solution provided by an embodiment of the present invention, the line card continues to send BPDU messages when the main controller is in active / standby switchover, so that the non-root switch does not detect network link disconnection and does not perform spanning tree calculation again.

Description

technical field [0001] The invention relates to communication technology, in particular to a switching control method and device, a switch and a computer-readable storage medium. Background technique [0002] The basic principle of the spanning tree protocol (Spanning Tree Protocol, STP) is to construct a network topology by passing bridge protocol data units (Bridge Protocol Data Unit, BPDU) between switches, and eliminate loops in the network. [0003] After STP converges, the root switch in the network needs to send BPDU packets to other non-root switches every 2s, and the non-root switches will forward the packets from ports other than the receiving port. If the switch does not receive the BPDU message from the root switch, it thinks that the network topology has changed, stops sending BPDU messages, and starts looking for a new root node (that is, the root switch). [0004] In a switch that does not implement hot backup of the control plane protocol, the master / standby...
