Port Mirroring

This section describes the Port Mirroring feature, which can serve as a diagnostic tool, debugging tool, or
means of fending off attacks.

Overview

Port mirroring selects network traffic from specific ports for analysis by a network analyzer, while allowing
the same traffic to be switched to its destination. You can configure many switch ports as source ports
and one switch port as a destination port. You can also configure how traffic is mirrored on a source port.
Packets received on the source port, transmitted on a port, or both received and transmitted, can be
mirrored to the destination port.
