Using Diagnosis
The EDS-510A 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.
Perform the following steps to set up the
Mirror Port
function:
STEP 1
Configure the EDS-510A’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
Select one of the following three watch direction options:
Input data stream
Select this option to monitor only those data packets coming
in
through
the EDS-510A’s port.
Output data stream
Select this option to monitor only those data packets being sent
out
through
the EDS-510A’s port.
Bi-directional
Select this option to monitor data packets both coming
into
, and
being sent
out through
, the EDS-510A’s port.
STEP 2
Be sure to activate your settings before exiting.

.
