Port Mirroring This lesson covers port mirroring, which is also known as a Switch Port Analyzer (SPAN) port. Port mirroring allows devices to see copies of the data that's going through a switch. It is able to capture and analyze packets and set up devices to capture data. SPAN ports are useful in that we can take data and figure out the type; i.e. and HTTP packet or perhaps a malicious packet.
