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.
