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 1-97.
Figure 3-29 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 to open the Port Mirroring Configuration screen.
