Port Monitoring
You can configure port mirroring on this page. 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 is selected as follows:
All frames received on a given port (also known as ingress or source mirroring).
All frames transmitted on a given port (also known as egress or destination mirroring).
Port to mirror is also known as the mirror port. Frames from ports that have either source (rx) or destination
(tx) mirroring enabled are mirrored to this port. Disabled option disables mirroring.
