5.10.3 Port Monitor
– Mirror Configuration
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 to
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.

Description
Port
The switch port number to which the following settings will be applied.
Mode
Drop-down list for selecting a mirror mode.
Rx only
: only frames received on this port are mirrored to the mirror port. Frames
transmitted are not mirrored.
Tx only
: only frames transmitted from this port are mirrored to the mirror port. Frames
received are not mirrored.
Disabled
: neither transmitted nor received frames are mirrored.
Enabled
: both received and transmitted frames are mirrored to the mirror port.
Note
: for a given port, a frame is only transmitted once. Therefore, you cannot mirror
Tx frames to the mirror port. In this case, mode for the selected mirror port is limited to
Disabled
or
Rx only
.
