To indicate which program is needed to open it
Answer:
The switch technology that the network administrator will need to use to configure a switch to copy traffic that occurs on some or all ports to a designated monitoring port on the switch is called port mirroring. To best illustrate how port mirroring works, I will use an example.
Explanation:
Assume we have two PCs connected to a switch. We also have an analyzer or a monitoring computer connected to the switch. If PC 1 sends a message to PC 2, we can configure port mirroring which is also known as SPAN to allow a copy of the message sent to PC 2 to be sent to the monitoring computer. A copy of this information will not be sent until this feature in enabled on a switch. It is that simple.
Thus, if a network administrator enables this feature on a switch; all network packets sent to all ports of a LAN or an entire VLAN from a single source port will be copied to a monitoring device or a sniffer for packet analysis. The key point here is to send the traffic information that originates from a single source host to several other host devices on the network and then back to the monitoring port of the switch.
