3.13 Using Diagnosis
The Weidmüller switch provides three important tools for administrators to diagnose network
systems.
3.13.1 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.
Perform the following steps to set up the Mirror Port function:
STEP 1
Configure the Mirror Port function from either the Console interface or Web Browser interface. You
will need to configure three settings:
