Port Mirroring
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 mirrored 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. To view the
Port Mirroring window, click Port
Mirroring in the Administration folder.
