Configuring the GbE Interconnect Switch Using the Web-Based Management Interface

Configuring Port Mirroring

When you select Port Mirroring from the Configuration menu, the following screen is displayed.

The GbE Interconnect Switch allows you to copy frames transmitted and received on a port, and to 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.

IMPORTANT: You cannot mirror a faster 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 you are copying frames from should always support an equal or lower speed than the port to which you are sending the copies. Also, the target port for mirroring cannot be a member of a trunk group. A target port and a source port also cannot be the same port.

To configure a mirror port:

1.Select the Source Port from which you want to copy frames.

2.Select the Source Direction, either Ingress, Egress, or Either.

3.Select the Target Port that receives the copies from the source port. This is the port where you would connect a monitoring or troubleshooting device, such as a sniffer or an RMON probe.

4.Select Enabled in the Status field.

5.Click Apply.

NOTE: To save the configuration settings permanently, you must enter them into NVRAM using the Save Changes option on the Maintenance menu. Refer to the section, “Saving Changes,” earlier in this chapter.
