Mirror

The Switch allows you to copy frames transmitted and received on a port and redirect the copies to another port.
You can attach a monitoring device to the mirroring port, such as a sniffer or an RMON probe, to view details about
the packets passing through the first port. This is useful for network monitoring and troubleshooting purposes.
