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-7828’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 two watch direction options:
y
Output data stream
Select this option to monitor only those data packets being sent
out
through
PT-7828’s port.
y
Bi-directional
Select this option to monitor data packets both coming
into
, and
being sent
out through
, PT-7828’s port.
STEP 2
Be sure to activate your settings before exiting.
•
When using the Web Browser interface, activate by clicking on the
Activate
button.
•
When using the Console utility, activate by first highlighting the Activate menu option, and
then press
Enter
. You should receive the
Mirror port settings are now active! (Press any key
to continue)
message.
Ping
The
Ping
function uses the
ping
command to give users a simple but powerful tool for
troubleshooting network problems. The function’s most unique feature is that even though the
ping command is entered from the user’s PC keyboard, the actual ping command originates from
PT-7828 itself. In this way, the user can essentially sit on top of PT-7828 and send ping commands
out through its ports.
To use the Ping function, type in the desired IP address, and then press
Enter
from the Console
utility, or click
Ping
when using the Web Browser interface.
