Port Mirroring
The Switch allows you to monitor traffic going in and out of a particular port. For traffic monitoring to work, you need to attach a network analyzer to one port and use it to monitor the traffic of other ports in the stack.
To set up traffic monitoring, you need to set an analysis port (the port that is connected to the analyzer), and a monitor port (the port that is to be monitored). Once the pair is defined, and you enable traffic monitoring, the Switch takes all the traffic going in and out of the monitor port and copies it to the analysis port.
CAUTION: The analyzer port should have a higher bandwidth than the mirror port. Otherwise, the Switch may not be able to copy all traffic effectively during periods of high traffic.
