Port Mirror
The Port Mirror function can be used to monitor data being transmitted through a specific port. This is done by
setting up another port (the mirror port) to receive the same data being transmitted from, or both to and from, the
port under observation. Using a mirror port allows the network administrator to sniff the observed port to keep tabs
on network activity.
