As shown in the Port Mirroring Configuration screen example (Figure 3 "Port
Mirroring Configuration port-based screen example" (page 19)), port 23 is
designated as the Monitor Port for ports 24 and 25 in Switch S1.
Note: The Unit value (in the Unit/Port field) is not configurable when the
switch is operating.
The Monitoring Mode field [ - > Port X or Port Y - > ] indicates that all traffic
received by port X
or all traffic transmitted by port Y is currently being
monitored by the StackProbe attached to Monitor Port 23.
The screen data displayed at the bottom of the screen shows the currently
active port mirroring configuration.
