Port mirroring
Port Mirroring is used to configure, enable, and disable the monitored port. When enabled, network packets being
sent and/or received on a target port are duplicated and sent to a monitor port. By attaching a network analyzer to
the monitor port, you can collect detailed information about your network performance and usage. Port mirroring is
disabled by default.
NOTE: See the ―Troubleshooting tools‖ appendix in the N8406-023 1Gb Intelligent L3 Switch Application
Guide for information on how to use port mirroring.
The following table describes the Port Mirroring Configuration commands.

Description
Adds the port to be mirrored. This command also allows
you to enter the direction of the traffic. It is necessary to
specify the direction because:
If the source port of the frame matches the mirrored
port and the mirrored direction is ingress or both
(ingress and egress), the frame is sent to the mirrored
port.
If the destination port of the frame matches the
mirrored port and the mirrored direction is egress or
both, the frame is sent to the monitoring port.
Command mode: Global configuration
Removes the mirrored port.
Command mode: Global configuration
