Port Mirroring
Port mirroring (also called port spanning) is a tool that allows you to mirror the traffic from one or more ports
onto another port, without disrupting the flow of traffic on the original port. Any traffic that goes into or out of
the Source Ports is duplicated at the Destination Ports. This traffic can then be analyzed at the Destination Port
using a monitoring device or application. The network administrator typically utilizes this tool for
diagnostics, debugging, or fending off attacks

Select Enable or Disable to enable/disable port mirroring.
Source Port
This is also known as Monitor Port. These are the ports that you
want to monitor. The traffic of all source/monitor ports is copied to
destination/analysis ports. You can choose a single port, or any
combination of ports, but you can only monitor them in Rx or TX
only.
Click the check box of the Port ID, RX, Tx or both to select the
source ports.
Destination Port
This is also known as Analysis Port. You can analyze the traffic of
all the monitored ports at this port without affecting the flow of
traffic on the port or ports being monitored. Only one RX/TX of the
destination port can be selected. The network administrator
typically connects a LAN analyzer or Netxray device to this port.
