4.3.30 Mirror
To debug network problems, selected traffic can be copied, or mirrored, on a mirror
port where a frame analyzer can be attached to analyze the frame flow.
The traffic to be copied on 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
on this port. Disabled disables mirroring.
Mirror Port Configuration
The following table is used for Rx and Tx enabling.
Items
Description
Port
The logical port for the settings contained in the same row.
Mode
Select mirror mode.
Rx only Frames received on this port are mirrored on the mirror port.
Frames transmitted are not mirrored.
Tx only Frames transmitted on this port are mirrored on 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 on the
mirror port.
Note: For a given port, a frame is only transmitted once. It is therefore not possible to
mirror mirror port Tx frames. Because of this, mode for the selected mirror port is
limited to Disabled or Rx only.
