Port mirroring
Command: /cfg/pmirr
[Port Mirroring Menu]
mirror - Enable/Disable Mirroring
monport - Monitoring Port based PM Menu
cur - Display All Mirrored and Monitoring Ports
The Port Mirroring Configuration Menu 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.

Command
Description
add <mirrored port> in|out|both
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.
rem <mirrored port>
Removes the mirrored port.
delete
Deletes this monitored port.
cur
Displays the current settings of the monitoring port.
