Abstract
A repeater device in a communication network includes a microcomputer configured to determine whether the repeater device will function as a mirroring switch that generates and transfers a mirror frame, or as a mirror-transfer switch that transfers the mirror frame. When the repeater device functions as a mirror switch and performs port mirroring, the repeater device adds monitor port and destination port information of the mirroring switch to the mirror frame. When the repeater device functions as a mirror-transfer switch, the repeater device adds sender port and destination port information of the mirror-transfer switch to the mirror frame. A monitor device in the communication network uses information in the mirror frame to identify a mirror source device in the network.
