4.18 Mirroring Configuration
Configure port Mirroring on this page.
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 on
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.
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 Tx frames
on the mirror port. Because of this, mode for the selected mirror port is limited to
Disabled or Rx
only.
