Configuring Port Mirroring

Configuring 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.

Supported Mirrors

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 "Configuring LACP" on page 4‐55.

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).

Purpose

To review and configure port mirroring on the device.
