Port mirroring does the following:
•Monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from one port to a monitoring port.
•Can be used as a diagnostic tool and/or a debugging feature.
•Enables device performance and monitoring.
Port mirroring is configured by selecting a specific port to copy all packets, and different ports from which the packets are copied.
Before configuring Port Mirroring, note the following:
•Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets, from a monitored port to a monitoring port.
