Using Diagnosis
The EDS provides two important tools for administrators to diagnose network systems.
Mirror Port
The
Mirror port
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. This allows the network administrator to
“sniff” the observed port and thus keep tabs on network activity.
