4.3.5 Port Sniffer

The Port Sniffer (mirroring) is a method for monitor traffic in switched networks. Traffic through a port can be monitored by one
specific port. That is, traffic goes in or out a monitored port will be duplicated into sniffer port.

Figure 4-3-5:

Port Mirror application

Configuring the port mirroring by assigning a source port from which to copy all packets and a destination port where those
packets will be sent.
