3.4 OVERVIEW: PORT MIRRORING
The Matrix device allows you to mirror (or redirect) the traffic being switched on a port for the
purposes of network traffic analysis and connection assurance. When port mirroring is enabled, one
port becomes a monitor port for another port within the device.

The following types of ports can participate in mirroring on the Matrix Series device:
• Physical ports, including front panel and FTM-1 ports
• Virtual ports, including Link Aggregation Group (LAG) and host ports. For details on
configuring ports for link aggregation, refer to Section 3.5.
3.4.2 Active Destination Port Configurations
Each Matrix DFE-Gold Series device supports three mirroring destination ports, which can be
configured in a many-to-one mirroring configuration (that is, many destinations mirrored to one
source port).
