4.2.7 Overview: Port Mirroring
The Matrix E1 allows you to mirror 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 switch. When configuring port mirroring on
this device, note that
• Only one mirror is allowed per device;
• Only one mirroring session is allowed at a time;
• Traffic mirrored includes both received and transmitted packets;
• Unknown protocol packets and broadcast packets can be forwarded out the monitor port when
mirroring is enabled.
For details on how to specify port designation in the CLI syntax, refer to Section 4.1.2.
