 ## Switched Port Analyzer (SPAN)
 Port mirroring is used on a network switch to send a copy of network packets seen on one switch port to a network monitoring connection on another switch port.
-Can be used by network engineers or administrators to measure performnce, analyze and debug data or diagnose errors on a network.
