Port Mirroring Configuration screen
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 Chapter 1.
Figure 79 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.
To open the Port Mirroring Configuration screen:
➨
Choose Port Mirroring Configuration (or press i) from the Switch
Configuration Menu screen.
