Using Diagnosis
The PT-7728 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.
Take the following steps to set up the
Mirror Port
function:
STEP 1
Configure PT-7728’s
Mirror Port
function from either the Console utility or Web Browser
interface. You will need to configure three settings:
Monitored Port
Select the port number of the port whose network activity will be
monitored.
Mirror Port
Select the port number of the port that will be used to monitor the
activity of the monitored port.
Watch Direction

y
Output data stream

out
through

y
Bi-directional

out through
, PT-7728’s port.
