This dialog allows you to configure and activate the port mirroring
function of the device.
Select the source ports whose data traffic you want to review from the
list of physical ports by checkmarking the relevant boxes.
You can select a maximum of 8 source ports. Ports that cannot be
selected are displayed as inactive by the device, e.g. the port
currently being used as the destination port, or if you have already
selected 8 ports. Default setting: no source ports.
Select the destination port to which you have connected your
management tool from the list element in the "Destination Port"
frame.
The device does not display ports that cannot be selected in the list,
e.g. the ports currently being used as source ports. Default setting:
port 0.0 (no destination port).
Select "On" in the "Function" frame to switch on the function. Default
setting: "Off".
