Mirroring
Configure Port Mirroring on this page.
To debug 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 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 disables Mirroring.

Label Description
Port The logical port for the settings contained in the same row.
Mode Select mirror mode.
Rx only: Frames received at this port are mirrored to the mirror port.
Frames transmitted are not mirrored.
TX only: Frames transmitted from this port are mirrored to the mirror
port. Frames received are not mirrored.
Disabled: Neither frames transmitted nor frames received are
mirrored.
Enabled: Frames received and frames transmitted are mirrored to the
mirror port.
Note: For a given port, a frame is only transmitted once. It is therefore
not possible to mirror TX frames for the mirror port. Because of this,
mode for the selected mirror port is limited to Disabled or Rx only.
