Abstract
Port mirroring is achieved between ports on separate devices in a stack of communication devices by establishing a protocol for communications within a cascade connection forming the stack in which an indication is given of whether the communication is being sent to the mirror port in addition to its intended destination. This avoids increasing the volume of traffic in the cascade connection as would be the case if the original and mirror copy were sent separately.
