Port Mirroring

Port Mirroring This lesson covers port mirroring. Port mirrors are also known as Switch Port Analyzers and are commonly referred to as SPAN ports. Port mirroring can be set up on switches, routers and other devices. It allows us to set up ports that have all the data mirrored to it, captures network data and allows for IDS (Intrusion Detection Systems). Port mirroring takes all data and send it to where it needs to go as well as making a copy and sending to whatever devices are on a SPAN port.
