Configuring Port Mirroring
You can enable the device to do port mirroring of network traffic (packets) passing (incoming, outgoing or both) through a specific port. When port mirroring is enabled, the device copies all traffic passing through the specified port and sends it to a specific port for analysis or monitoring.
To configure port mirroring through the CLI, use the port-monitor command on the port interface that you want to mirror.
