Port Mirroring Configuration

The Port Mirroring Configuration screen allows you to configure a specific switch port to monitor up to two specified ports or two MAC addresses. You can specify port-based monitoring or address-based monitoring. In a stack configuration, you can monitor ports that reside on different units within the stack.

For more information about the port mirroring feature, see “Port Mirroring (Conversation Steering)” on page 1-82.

Figure 3-28 shows an example of a Port Mirroring Configuration screen, in a stack configuration, where port 12 (in stack unit 3) is designated as the monitoring port for ports 5 and 6 of stack unit 4. When installed as a standalone switch, the screen does not display the (Unit/) field designation.

Choose Port Mirroring Configuration (or press i) from the Switch Configuration Menu screen to open the Port Mirroring Configuration screen.
