5.10.3 Port Mirroring
Port mirroring function will copy the traffic of one port to another port on the same switch to
allow the network analyzer attached to the mirror port to monitor and analyze packets. The
function is useful for troubleshooting. To solve network problems, selected traffic can be copied
or mirrored to a mirror port where a frame analyzer can be attached to analyze the frame flow.
The traffic to be copied to the mirror port can be all frames received on a given port (also
known as ingress or source mirroring) or all frames transmitted on a given port (also known as
egress or destination mirroring). The port to which the monitored traffic is copied is called
mirror port.
