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 N8406-026 10Gb Intelligent L3 Switch
Application Guide for information on how to use port mirroring.
The following table describes the Port Mirroring Configuration commands.

port-mirroring monitor-port <port
number> mirroring-port <port number>

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.
