Configuring Port Mirroring
Mirror mode enables you to duplicate to another port all of the traffic originating from or terminating at
a single client device or access point. It is useful in diagnosing specific network problems. Mirror mode
should be enabled only on an unused port as any connections to this port become unresponsive.
Note
The 2100 series controllers, controller network modules, and Cisco WiSM controllers do not support
mirror mode. Also, a controller’s service port cannot be used as a mirrored port.
Note
Port mirroring is not supported when link aggregation (LAG) is enabled on the controller.
Note
Cisco recommends that you do not mirror traffic from one controller port to another as this setup could
cause network problems.
Follow these steps to enable port mirroring.
