Configuring Port Mirroring
The GbE Interconnect Switch allows you to copy frames transmitted and received on a port
and redirect the copies to another port. You can attach a monitoring device to the mirrored
port, such as a sniffer or an RMON probe, to view details about the packets passing through
the first port. This setting is useful for network monitoring and troubleshooting purposes.
NOTE: You cannot mirror a fast port onto a slower port. For example, if you try to mirror the traffic from
a 100-Mb/s port onto a 10-Mb/s port, you can cause throughput problems. The port from which you are
copying frames must support an equal or lower speed than the port to which you are sending the
copies. Also, the target port cannot be a member of a trunk group.
To configure port mirroring:
1. Highlight Configure Port Mirroring on the Configuration menu.
2. Press the Enter key. The following screen is displayed.
3. In the Source Port field, toggle to the number of the port from which you want to copy
frames.
4. In the Source Direction field, toggle to the desired direction.
5. In the Target Port field, toggle to the port that receives the copies from the source port.
The target port is where you connect a monitoring or troubleshooting device such as a
sniffer or an RMON probe.
6. Toggle the Mirror Status field to Enabled.
7. Highlight APPLY and press the Enter key.
NOTE: To save the configuration settings permanently, you must enter them into NVRAM using
the Save Changes option on the main menu. Refer to the “Saving Changes” section earlier in this
chapter.
