Port Mirroring
Network engineers or administrators use port mirroring to analyze and debug data or diagnose errors on a
network. It helps administrators keep a close eye on network performance and alerts them when
problems occur. It can be used to mirror either inbound or outbound traffic (or both) on single or multiple
interfaces. Port mirroring is used on a network switch to send a copy of network packets seen on one
switch port (or an entire VLAN) to a network monitoring connection on another switch port.
The following table describes the labels in this screen.
