Method and device for isolating switch ports

The invention provides a method and device for isolating switch ports, and relates to the technical field of communication. The method comprises the following steps: an operation and maintenance platform generates an isolation instruction based on an identifier of a target switch and an identifier of a target port input by a user; the target switch is a switch of a to-be-isolated port in the storage area network, and the target port is a to-be-isolated port of the target switch; the isolation instruction comprises an identifier of a target switch, an identifier of a target port and a target isolation port command for isolating the port of the target switch, the isolation instruction is used for indicating the first server to issue the target isolation port command to the target switch, and the first server is a server of a storage area network; and the operation and maintenance platform sends an isolation instruction to the first server. By pre-storing the isolation port commands of the switches of different
