For trafficmonitoring to work, you need to attach anetwork analyzer to one port and use it tomonitor the traffic of other ports in the stack.To set up traffic monitoring, you need to set ananalysis port (the port that is connected to theanalyzer), and a monitor port (the port that isto be monitored). Once the pair is defined, andyou enable traffic monitoring, the Switch takesall the traffic going in and out of the monitorport and copies it to the analysis port.CAUTION: The analyzer port should have ahigher bandwidth than the mirror port.Otherwise, the Switch may not be able to copyall traffic effectively during periods of hightraffic.
