摘要： A mirror packet control device includes a processor that detects a notification of a completion of movement of a first virtual machine from another device to the mirror packet control device. The processor refers, upon the detection of the notification, to first correspondence information to identify a transmission source that transmits a first mirror packet to the first virtual machine. The first correspondence information includes a first item associating first identification information of the first virtual machine with second identification information of the transmission source. The processor transmits a first deletion instruction to the transmission source. The first deletion instruction instructs deletion of a second item included in second correspondence information stored in the transmission source. The second item associates the first identification information with identification information of a first port of the transmission source through which the first mirror packet is transmitted to the first virtual machine.
