Configuring Port Mirroring
You can configure Port Mirroring on the SonicWALL NSA 2400MX to send a copy of network packets seen
on one or more switch ports (or on a VLAN) to another switch port called the mirror port. By connecting
to the mirror port, you can monitor the traffic passing through the mirrored port(s).

A VLAN trunk port can be mirrored, but cannot act as a mirror port itself. VLAN trunk ports are used to pass
traffic to other networking devices. By comparison, traffic arriving on a mirror port has already been handled or
sent to its destination, and the mirror port does not forward it again. Typically, the traffic is passed from the mirror
port to a computer where the administrator can use an application, such as Wireshark, to view the traffic content.
