monitoring to work, you need to attach a

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
