Port Mirroring Configuration
Port mirroring is a method of duplicating traffic seen on a particular port and sending it to
another port. This is used for analyzing traffic using a network sniffer. The port being
monitored is called the Mirrored port and the port used to analyze the traffic is called the
Analysis port.
Figure 23. Port Mirroring Screen
Select Port Mirroring from the Switch Configuration menu and then from the action line select
<edit>. By default port mirroring is disabled. Use the <spacebar> to enable port mirroring.
The screen above will now be displayed. Again using the <spacebar> select the Mirroring
State. There are three options:
•
RX: Received packets are only sent to the Analysis port
•
TX: Transmitted packets are only sent to the Analysis port
•
Both: Received and Transmitted packets are sent to the Analysis port.
Next using the <tab> key navigate to the Analysis port and select which port, using the
<spacebar>, is to be the Analysis Port. Again using the <tab> key scroll down through the
port list to select which port(s) is to be mirrored. Make the selection using the <spacebar>
which is indicated by a ‘*’. Ensure that the Port Mirroring Configuration is saved by selecting
<apply> in the action line. Please disable Mirroring State when finished, as Mirroring is very
CPU intensive.
