Abstract
An apparatus and method for port mirroring in a plurality of Peripheral Component Interconnect express (PCIe) interfaces includes, for each PCIe interface, output transmission ports for transmitting data to a central processing unit (CPU), receiving input ports for receiving data from the CPU, port-mirror-in (PM_IN) ports, and port-mirror-out (PM_OUT) ports provided in a PHY layer instance. The PM_OUT ports of each PHY layer instance is coupled to the PM_IN ports of a next PHY layer instance such that the PHY layer instances of the plurality of PCIe interfaces are connected in a ring bus architecture for mirroring one or more ports of the output transmission ports or the receiving input ports of a first active PHY layer instance can be mirrored to output transmission ports of a second PHY layer instance.
