Configuring Port Mirroring

You can enable the device to do port mirroring of network traffic (packets) passing (incoming, outgoing or both) through a specific port. When port mirroring is enabled, the device copies all traffic passing through the specified port and sends it to a specific port for analysis or monitoring.

To configure port mirroring through the CLI, use the port-monitor command on the port interface that you want to mirror.

To configure port mirroring:
1. Open the Port Mirroring page (Troubleshoot menu > Troubleshoot tab > Debug folder > Port Mirroring).
2. From the 'Enable Port Mirroring' drop-down list, select Enable:

3. From the 'Direction' drop-down list, select one of the following:
In = mirrors incoming traffic
Out = mirrors outgoing traffic
Both = mirrors incoming and outgoing traffic
4. From the 'Source Port (Port to Mirror)' drop-down list, select the port that you want to mirror.
5. From the 'Destination Port' drop-down list, select the port to where you want the mirrored (copied) traffic to be sent.
6. Click Apply.
